- The Alpha Centauri system is a fascinating and complex star system located in the southern sky, approximately 4.37 light-years away from Earth. It consists of three stars - Alpha Centauri A, Alpha Centauri B, and Proxima Centauri - and is the closest star system to our own solar system. The Alpha Centauri system has long captured the imagination of scientists and science fiction writers alike, and has been the subject of numerous studies and missions aimed at better understanding its structure and properties. With the potential for habitable planets and the prospect of interstellar travel, the Alpha Centauri system holds great promise for the future of space exploration and our understanding of the universe.
Join me as we see every aspect of this trip and elaborate on many mind-blowing interstellar travel facts!
Alpha Centauri is one of the closest stars to Earth, and it's potential as a future home for humans is a topic of much debate.
we'll explore this topic and explore what research is being done to explore the possibility of human life on Alpha Centauri.
this technology is still in its infancy and is currently not feasible for interstellar travel.
Another option is to use solar sails. Solar sails are a type of spacecraft propulsion system that uses the pressure of sunlight to produce thrust.

People commenting saying humans will never be able to do it but look how far humans have come since the early 2000s technology wise it will only get more advanced.
But this is one of those, the more we know, the more we know it would be impossible.
Look at it this way, an Astronomical Unit is the distance from the earth to the sun which is tens of millions of miles. Now there are 63,000 AUs in a light year. Now multiply that by 4.3 and that is your distance you have to cover. If you can travel at the speed of light, it will take you about 4.3 years to arrive, BUT it's not possible to travel in a ship that fast - not even close. It will take you about 100,000 years to arrive traveling as fast as we can in space. Questions?
We are a self destructive species. Our greatest scientific gadgets are military weapons that can obliterate planets and we as a species keep putting each other in a cross hair. I don't think we will ever be a interplanetary or intergalactic species because we will eliminate life here because of our stupidity and greed.
The time dilation examples are wrong, the values are inverted. Time aboard the spaceship would pass slower than it would on Earth, due to the higher velocity of movement of the former.
That is what I thought as well.
I had to quit watching after that. Just lost interest after they got it wrong.
While we’re mentioning issues, the narrator pronounces Proxima weird. Emphasis on the wrong syllable.
How could they screw up something that important ?
@@tiborpurzsas2136 I know right. Was really shocked when I heard that.
As a Small Boy , Six Decades ago, I asked an Old Black Gentleman about the Night Sky and He explained that this was called " Alpha Centauri " ! Awesome !
Whats with the weird capitalization?
How come turtles or parrots aren't mentioned as potential passengers on deep space projects with their long life expectancy? They eat less and are lighter than humans, too.
16:53 time dilation has the inverse effects of how you described, as you speed up, time slows down
It's not okay to make factually incorrect content in this space with the number of actual physicists out there making videos, and the number of viewers who have a good grasp of the basics (even if we haven't got time to collate our own videos).
I was just thinking, somebody should tell the folks who made "Interstellar" they need to get better science consultants. Wait, what was that? Kip Thorne? Really? The guy who makes Insane Curiosity must be the smartest person in the universe! He's proven wrong every physicist since 1907, when some random no-name dude first theorized time dilation. I see a Nobel Prize in someone's future!" I suppose that according to multiverse theory there exists a reality where/when the science in this video is accurate. So he's got that going for him.
Fear not though.
I KNOW the second the fine folks at Insane Curiosity realize the error they will either edit the video or add a note in the description explaining how exactly they could have made it through research, writing, producing, editing and publishing without saying "Hmm, something seems off" It's not like they transposed a number somewhere. I mean, they (a science channel) got the entire concept wrong! Then again, if you hear it on CZcams, it must be true!
Thank you. I had to turn the video off after that. Pure trash
As far as interstellar goes, we dont really know what happens to time in a wormhole.
Funny whenever they show rockets design for high speed interstellar travel they never show /explain how the rocket would slow down once it gets to the planet. Your moving at a percentage of light, your going to need a lot / the same or equal amount of energy to slow down in the vacuum of space.
Maybe just Flintstone it.
You mean like what happens when it's time to say "whoa mule"?
Can you imagine thousands of years of "Are we there yet? Are we there yet?"
Do they even do that anymore? You're 20 feet away from your parents, in a 10 position heated/cooled reclining seat, refrigerated snack bar in the arm rest, TV screen in front if you, phone, headphones to drown out the chatter...
We MIGHT one day make it to Mars for a SHORT visit and that is it. Space is brutally hostile and it is impossible to maintain the delicate balance for human survival that far out.
We could have widespread space travel in hundreds or thousands of years.
Reality is we most likely will not attempt sending people to another system until we have established ourselves in our entire home system. Allowing refuel, or repair at a significant chunk of the distance.
At present, the closest star and exoplanet to us are impossibly far away. The fastest man made object so far, Parker Solar Probe, which doesn't carry any humans on it, and is using the sun's gravity for acceleration - would take 11,000 years to reach proxima centauri. Even if we could go 100 times faster, that is still over 100 years to get there. Humans don't live long enough to reach other stars in any foreseeable future. And, its interesting to think what sort of alien life form could and would make the journey from where they originate to here, considering the incredible distance. They'd need incredible tech and super long life spans, neither of which we have.
If we can figure out 1g constant acceleration then we could be at proxima centauri in less then 1 year. A long time would have passed on Earth 🤷🏽♂️
If the aliens are anywhere far past advanced where we are intellectually, which in all probability, they are, then they have supposedly, already made the trip to us, from their home world.
@@erichayes2890 You didn't respond to the points I made. They need either to live for (many) thousands of years or have tech WAY beyond what we have, or both. Which do you think they have? In either case, they will be nearly omnipotent compared to us.
@@BrianStDenis-pj1tq Who knows. You are right. Could be either one or the other or both. Who is to say. Note: I responded this time!
Even if we could reach other earth like planets, they have a good chance that they wouldn't be habitable. Like imagine an earthlike world twice as big as our own. The gravity would be too much. Or imagine a world with 2 stars. The lifeform there would have to adapt to high ultraviolet radiation, an adaptation we lack. We should concentrate our efforts on making life better in our own place in the universe
17:02 Isn't that time dilation backwards? Wouldn't it be 1 year on the spacecraft and 10 years for the earth observer? If time slows the closer to light speed then it seems the traveler would arrive back to a much older earth bound twin.
You are right. According to Einstein, if you travel even close to be speed of light for say, 5 years. 250 years will have passed on Earth.
Even if the technology to go at a significant fraction of the speed of light were to be developed, there would still be many problems:
1. No-one knows what parts of the spacecraft might break down, so probably at least two replacement parts of every essential component would be needed, which would be an enormous amount of extra weight.
2. There would have to be plenty of emergency procedures for the possible holing of the ship - any leak would have to be detected and mended very speedily.
3. Even though the craft would have to be almost perfectly hermitically sealed, some loss of materials would take place and so there would have to be extra supplies to cover this.
4. There are numerous possible health problems which could occur due to the journey and all the others which would happen naturally such as cancer. How would these be dealt with? What if the journey were compromised by too many of the crew being ill or dead to guide the ship.
5. What provisions would there be for unrest, say some of the crew want to end the journey and return to Earth? How would any social unrest be dealt with?
These are just problems off the top of my head. There will be many problems only experts know of and many which the first human explorers discover for themselves .
Sounds like cryogenics would solve a good portion of the human problems. That isnt too far beyond current tech
@@user-iv2iu2wf4w Maybe! Although they have been talking about cryogenics and, , "revivifying" dead people who had enough money to be frozen for a long time, at least since the 70s. As I understand it, there were problems in the cell damage caused in all three stages of the process, i.e. freezing, storing and bring them back to life. Although, I accept you're talking about cryogenically preserving live people, so that they can go to distant stars.
Don't sign me up. My wife wants me home for dinner.
BTW: your example of time dilation had the number of years reversed. 😳
We're talking about a trip of 11,000 years. That's longer than the time between the invention of writing and now. 11,000 years ago we were hunter-gatherers. 11,000 years from now, who knows what society and technology will look like on Earth. Nobody can predict that. Nobody could have predicted our current society 11,000 years ago.
One thing is certain: a group of people aboard a spaceship won't change much, societally, in that time, and definitely not the same changes as we who remain on Earth. The people who travel to Proxima Centauri won't even be members of the same civilization that remain here on Earth. Communication will be almost nil, since any exchange of messages will have a roundtrip timelapse of almost nine years. And with the cultural differences that would arise, what would we even talk about?
Imagine getting there and discovering there are no habitable places to land. Like...not even remotely habitable.
That would be messed up
When one side permanently facing the stat and the other constant darkness then there's a bearable temperature in the twilight zone between the 2 sides
Hundreds of years? What sane person would condemn their children (and subsequent generations), to spending their entire life trapped inside a metal box, just to take some rock samples?
Lolol yes that's right u made a good point. Who knows perhaps some ppl will go with the idea to collect samples but secretly thinking they will find an Eden reality where they can make their dreams come true😂
And more importantly, an awesome selfie.
I found the book ' A Journey ( or Voyage ) to Alpha Centauri ' at the town library in the late 1960's, it was a well thought out journey of a generation ship. I don't remember the name of the author, but now in my retirement I would be interested in reading it again, but haven't been able to track down a copy.
Look it up and the publishing date i.e. 1960s. It should be traceable unless it wasn't widely published or only published locally.
It does sound interesting. If for no other reason than to compare the details in the thinking from 60 years in the past to the ideas of today.
I have been of the opinion that much needs to be established in our own system before we will send people on that kind of journey. I think we need to have a self sustaining space economy before we can put people on a ship to go 4+ LYs away. We need to kind of build our way deeper into space. Create truck stops through the solar system. Habitats that can refuel and can increase or decrease speeds the ships will travel. Repair damages before the last of our Ort cloud is left behind. I could go on but boredom for you would be terrible. Basically build our way out into the galaxy. Everywhere we go is a new addition to the ever growing highway system we slowly build through the galaxy.
Forget it. The Jupiter II is already 25 years behind schedule and we couldn't afford it anyway.
@@jssomewhere6740 Exactly why I want to find it again, one chapter was devoted to speculation about an object travelling on a perpendicular course but crossing 100's of thousands of miles ahead, assuming it was another ship. Now we know interstellar space also contains some pretty quick junk. You are not boring when speculating about space, I, and then my wife and children became TREKKIES !!
@@krashdown5814 I believe we will extend out into the Galaxy. We may be the aliens we finally find in a million years. Cuz by then we may no longer recognize our descendents or they us. Humans have always looked for adventure, we are explorers. Especially in the beginning trips will be one way yet we will still go. I wish I could be around to see it. I'm hoping for boots on Mars before I let entropy have its way with me and I step back into the flow of time. I was little when Armstrong uttered his famous line. I'll be old when the first steps are made on Mars. That will be good.
This has to be the most beautiful voice I’ve ever had the pleasure of listening to
Steam populations, plenty of both water & heat in space?
The Jupiter 2 left Earth to go there back in the 1960s and still hasn't got there...."Danger! Danger,Will Robinson!! DANGER!!"
Jupiter 2 has been boxed up and stored decades ago after the phoney launch and parachuting onto a NATO controlled site in Antarctica.
No kidding! Check back again in about 50 to 80,000 years!
Do you mean the voyager 2?
@@zakariaabdimohamed7063 I was referring to the original "Lost in Space" T.V. show from the 1960s...the plot was the Space Family Robinson was going there when their ship the Jupiter 2 was sabotaged by Dr. Smith.
@@mikeburkhart8336 oh ok.
To put this into perspective, the furthest humans have been from Earth is the Moon.
The Moon, approximately 1.3 light seconds.
Proxima Centauri, approximately 4.37 light years.
Or roughly 1/106,079,908 th of the way there!
Is the narrator of Insane Curiosity videos a real person or AI? If it's AI, it's the best computer voice I've ever heard, if it's a human, what a great voice.
It' s real, we actually don't work with A.I. :)
Indeed. You have time dilation backwards and you said it would take 10s of thousands of years right after you said certain propulsion systems could tech a significant percentage of the SOL.
You need to reign in your writers.
@@InsaneCuriosity Oh that makes me happy, thanks. One of the best sounding voices for narrating videos I've ever heard. The tone, cadence, timbre....just perfect. Love this channel, keep up the great work.
It is a real Person, I Seen Who it Was on An Other Vedeo....
@@minombremiapedillo534 what does he look like?
Minute 17:00 is wrong , the faster you travel the slower the time passes so in your case you explained it wrong on earth would pass 10 years but only 1 on the ship at 90 percent of light speed
How many spaceman we need, up there, to have GPS?
You got the twin paradox wrong. Time is slower in the spaceship and faster on earth...
this is kind of big mistake
There are some errors in the video. The weakness of gravity has a greater influence on the time of the gps satellites then the speed. Their clocks are running 45 microseconds per day faster then the clocks on earth. On the other hand, the speed makes them slow down only 8 microseconds. This also means that a clock on a spaceship flying close to the speed of light will appear slower compared to a clock on the earth, not faster.
We will know alot more in 75,000 years when Voyageur II gets there.
We'll probably lose connection at that point.
@@ericgolightly8450it's a joke😊
Great video !
It’s very interested to me while watching “A Journey To Alpha Centauri “ as the beat scientific & educational documentary in CZcams.
Yes aliens from Alpha Centauri B have already visited EARTH WAY BK 1961 TO 1962 AND MET SPS BARNEY AND BETTY HILL FROM NEW HAMPSHIRE OF USA. PLS REFER YO YOU TUBE IN THAT YEAR.
I think at this point, if they could do a moon base and perhaps a Mars base, that would be an achievement in itself (the latter being a bit more difficult perhaps due to the amount of time -- moon base could be done much quicker probably since the moon is closer, and we've studied it a bit more (in person and with equipment). I think even a small scale test of say 20 people would be interesting.
Cool, love it.
Nuclear propulsion is a process that originates from reverse technology. When the craft from Zeta Retticulum landed at area 52, scientists had a look the structure of the craft and adapted it to our limits of understanding, control and development. That will still take time to fully develop
Reverse technology is not enough when our scientists are developing spacecraft. Zeta Grey is neither our friends nor galactic council member, yet they are pay more attention to area 52, underground facilities, and Antarctic bases.
However, Andromeda council have in charge of the largest interstellar gates on the earth for against their darkness experiments, and then Zeta Grey had lost many bases over the past decades.
The most advanced populsion systems are still controlled by galactic council and Arcturian. We don't trust Zeta Grey, they are on the black list of Andromeda galaxy.
In the year 1500, the concept of nuclear power and the atom bomb, or even the internal combustion engine seemed unheard of an insurmountable. Perhaps, in 2 to 3 centuries travel to other star systems will be as routine as traveling to other countries by plane.
It is unlikely that Proxima B has surface oceans or an atmosphere due to the flaring nature of the parent star.
There may be more suitable planets in orbit around Alpha Centauri A and B.
That is what I was thinking. Alpha Centauri A and B are more like our sun and if they had a rocky planet in the habitable zone then it has the potential of being more Earth-like.
Would there be orbital perturbations between A and B that would make potentially habitable planets wildly irratic? Agree with you about Proxima B
I don’t know where Proxima Centauri is really relative to our solar system. I guess what I would be curious to know is if the PC system is-in front, or behind us-so to speak.
Like since we know that our solar system orbits the center of the galaxy, would it be “faster” to launch a craft towards a system that is in effect behind us? So then as we moved toward it, it would also be moving toward us?
Of course this would make the return trip much longer I assume.
Bah! All this is mute. We already use probes for most of out space exploration. I don’t think that humans in space will ever be possible.
Eventually we’ll have to creat AI. Advanced enough bodies for them. Technically the AI on ship and the bodies could function as a whole of the same AI.
This is honestly the only way I see space explorations as feasible. As humans we have to take our whole environment with us. Food, water, oxygen, gravity being the main ones that come to mind.
Without gravity, any baby’s born in zero G- their development would be so unknown. They would obviously have very low bone density and muscle development.
2 games introduced in the video, I can recommend it to kids too!
the games inspires young generation to intersteller travel and encourage them learning science.
The Robinsons tried to make it there too and they ended up joining through space for a long time trying to find out where they are LOL
Cand ajungi aici, mergi la televiziunea planetara Centaureza si da-mi un apel. Sunt aproape, in munții Roco-Coco, vin repede.
Good answer. Thank you
I'm getting on board the next flight I can hardly wait
Engines are a nice thing, but leaving out the fuel Problem, the SpaceX Starship as proposed has the strongrst Engines we ever build, it can for some time Producer a thrust of 5G....but for a crewed Mission, the Limit except for short times is 1G,or the High-G Stress would be hazardous for the human body, if not after a long enough time out right lethal.
So faster Engines dont make the Trick as long as the Crew dont survive the G stress.
Imagine going on a mission for 10,000 years to another system and but then 200 years after they launched, we develop faster than light speed…. Would we pick them up? Or just leave them to themselves and have our ancestors greet them when they arrive in 9800 years. 😂
Let them make the trip and we'll greet them when they get there if they get there
You saw him answer that question on one of his older videos.Nice try attempting to be intelligent.
It would be our decendants, not ancestors...our ancestors are the people who came before us, our decendants are the ones who come after us...
What you could do is have some kind of solar panel renewable energy system attached to the solar sails to provide energy and light for plants inside the ship to photosynthesise and grow food for the crew members. The crew member give the plants CO2 and water and in return, the plants give you Oxygen and food. Water can be recycled through the ship and the plants so no water is lost and urine can be filtered back into water and faeces can be used to help fertilise the soil for the plants.
What if You Catch a Ride with A Traveling Astroid or Comet, Then While on the Astroid or Comet Attach a Few Rockets For Thrust and Drive The Astroid to Alpha Centuri at a Faster Method With The Astroids Perpolsion and Extra Thrust To Drive That Astroid Like a Space Plane....
I know others have said it, but the time dilation examples are wrong and backwards. The bigger issue I take is that there is no way we are getting to 90% the speed of light, but time dilation is still in play because of the high speed they will be going over the long period of time. Just like the GPS satellite issue.
Because of Proxima B being "earth" sized, I highly doubt we (people) would land on it, because you would need a ton of energy to get back off
Wow, only 4.3 light years away. Based on our technology, that would take us 6000 to 10,000 years to get there. I'm going to go pack my travel bag right now!
And half way you have to hit the break or you fly by your destination. So count for 12000 to 20000 years.
@@RogerJonker Good point.
wait for warp drive to be invented, it could make the trip faster than light, but it will take a long time to develop
@@nextlevelenglish5858 Almost as long as creating PEACEFUL FUSION!
@@johncipolletti5611 are you meaning coldfusion?
That's why I think it would be smart to design a space habit like a O'Neal Cylinder that's also capable of operating as a spaceship that way when you get there you already have a base of operation in which to operate from as you also would already have ships capable of coming and going to a planet or other places where you can safely land a ship.
Having been watched through this video, I learned "how great No Manns sky"is.
What if we get to proxima c-b and it is habitat by someone else.
It's highly unlikely we'll ever make it even to the nearest star system unless there is a revolution in propulsion which doesn't seem likely anytime in the next century or two. Unless the time to reach Alpha Centauri can be reduced to under 50 years. Anything longer would be impossible for humans to endure. Imagine being holed up in a tiny spaceship for even just decades. It would drive humans insane.
@jayclarke6671, exactly my thoughts.
They'll probably be giant arks propelled by inertial fusion engines. It could reach a significant fraction of the speed of light in a few months.
That would take an effort and a lot of money in research. But us humans are too busy killing each other in useless wars for any effort like that to take place !
Plus, where would be the nearest charging station, being as we are going all Electric? 😂
What about Warp drive?
We need a launch window n trajectory ? I mean I’m sure by then we will come up with some type of gps 😂😂
It takes light years to get in between the stars. Idk what GPS would do to help though.
Elite Dangerous has the most scientifically accurate representation of Alpha Centauri system out of any game by far, and in it its stated that Proxima B is uninhabitable, in fact all planets in the system are.
With such leaps and bounds in scientific discoveries it all seems only a matter of time. 🙉
Light Years Away 😁
To all our descendants who will reach the Proxima Centauri system after many centuries
Congratulations I hope you guys still can read this 🎊
2,000 years from now, nobody shall even remember that You Tube had ever existed. "For, behold, I create new heavens and a new earth: and the former shall not be remembered, nor come into mind" (Isaiah 65:17, KJV).
If people today are still reading the Bible from 2000 years ago, why wouldn't they have access to medias created today?
There is absolutely no way hat there will ever be an attempt to launch a mission to another star system until such time that warp drives are practical. A 400 generation mission? That's laughable.
How about a giant 1 or 2 generation ark?

So with solar sails, if they reach Proxima, would the photons have a reverse affect and blow the sails away from Proxima?
Was thinking the same😮
I guess it would slow the sail down at its destination. So it still works out.
No way is a space craft designed to take s crew of a size needed to go the distance spoken of,is launched in a single launch. The craft needed would require multiple launches and some assembly in Earth or more likely the Moons orbit. This craft will also require multiple propulsion types. Fueling would also be done in space. Chances are there will be more than one craft to act as a safe guard. The biggest problem is not propulsion it's shielding. Something that could be repaired or replaced during the trip. That doesn't cover even a small percentage of the challenges to make the spoken of trip.
It might be a large fleet of also large ships and arks.
@@ericgolightly8450 that is certainly a possibility. It would boil down to cost. Sending 250 people on a 4+ LY journey would represent a monetary cost of an unbelievable amount. Meaning the nation's of the entire planet would need to take part. There in lies the hard part. We have trouble agreeing to feed everyone. Convincing the devolved nations of the world that a significant % of their GDP needs to be given over in the name of exploration will be difficult to say the least.
I would love to explore an alien world such as "Planet Serpo". After reading the book "A Secret Mission To The Planet Serpo" I was fascinated of what Serpo like......

Is it possible to travel to the stars ? In a limited way, maybe. Let me be more clear. The nearest star (a binary system) is Alpha C, five light years away but there are at least ten stars within ten light years away. While staying within the laws of physics as we know them it would be at least that long to get there and that much to return. To go to almost light speed you would accelerate at one earth gravity for about a year. You could stand that, then for four to ten years you would coast at near light speed. En route your craft could be like a spinning wheel so centrifugal force would throw you out to the edge and so supply artificial gravity. When you get near then you turn the craft around and decelerate to the destination. So add two years to the trip. Then you spend what time you want exploring then return. What we don’t at present know is if interstellar space has anything solid in it that you might hit. At that speed it would hurt you. Expect Einsteinian time dilation so to you it wont seem so long as it will actually take. We have the Voyager probe out there now and it is fifty years old. Perhaps you want to send a very advanced AI to do the first survey trip. You might leave a string of relays to enable reporting back what you find. Then your near descendants will have contact with the nearest stars. That is all nearly possible. You still need a means of propulsion that needs no fuel. Atomic or maybe fusion energy could do that but then you still need to convert that energy to thrust. We don’t have that yet but we are working on it. That is at least more possible than scifi space warps or ftl drives. Hopefully that is in the future, then the light speed craft can be met when they arrive. I would not count on that. The idea of ftl travel may be the modern philosopher's stone. You think it could exist but its just not possible.
Only ten stars ? If you don’t plan to come back, maybe in a sleeper ship, it could be more. If the probes have a way to communicate back, they are AIs, and they don’t decelerate maybe they might reach out more. If they are just probes they would enter a cometary orbit and stay there collecting data. If there is anything interesting out there the probes could let us know.
That might be dangerous. Suppose the Easter Islanders had gone exploring and they contacted the Spanish ? The Galaxy could be, as Cxin Liu has said, a "Dark forest".
Solatr sai;s wont really work once you get to the outer solar system because the the light intensity from the Sun is stolidly low (lasers could augment this).
@16:43, your example explaining time dilation was incorrect, it`s effect to the astronauts vs. observers on earth was vice versa.
Awesome video and keep the videos coming till we get to a Type 1 Civilization in about 100 years in the future...
Interstellar space travel is a dream, never going to happen.
A trip to Alfa Centauri will take at least 50000 years at the speed of the Voyagers. A very very long time.
Just a blip in the grand scheme of things those numbers may just be what it takes to get to other stars maybe we can shorten it some but space it’s big we just need patience for this part of our species expansion
Because of the size that the ship would have to be it would need to be assembled in space because it would need to be gigantic. Next thing you totally missed it on explaining Time Dilation, the outcome would be opposite of the way you broke it down. Depending on the top speed of the spacecraft somewhere around the middle of the flight or beyond you need to start slowing down. It will not be like coming to a stop at a red light. You will need around the same amount of fuel to slow down as you did to speed up and like I stated you will need to start the slowing process a long time before you arrive.
We don't need to travel light years IOT find uninhabitable trap houses, we have plenty of those right within our own solar system.
My question is why would you even consider colonizing a planet around a dwarf star logic says you be looking for a son exactly like ours so your search should start there
So think about this:
Four hundred generations of people come and go during this trip. We're assuming the people who arrive are going to be interested in and capable of performing the scientific research we're hoping to accomplish. Why would they be interested in sending information back to a civilization they're not even a part of. A civilization that existed so long ago they feel no sense of connection. They might even feel animosity to the people of Earth who doomed them to fates they never would have wanted for themselves.
we dont have starships capable of getting there. not any time soon. its 4.367 light years away. any thoughts on when we could exceed the speed of light?
Yes, we need a whole new way of propulsion.

We will never achieve Interstellar Space travel until we take Rocket propulsion out of the equation. Wormholes, Warp, gravity wave. I know Science Fiction, but I can't fathom a 100-year trip to Proxima Centauri. Too many things can & will go terribly wrong.
Apparently you can use video games to simulate travel to Proxima B and other planets. Extended advertisements for two games - something about Starship Warlords and No Man's Sky - are almost word-for-word identical, proving that this narration was generated by GPT. But, in No Man's Sky, planets are procedurally generated, meaning that no two journeys to the planet will be the same. What's the point of that? And furthermore, there is no mention of SPACE ENGINE, which surely IS scientific and more accurate, at least to the extent of human knowledge. x
Unfortuately this video is not up to date. Some time ago, a 3rd planet was discovered in the Proxima Centauri system.
I just wondered why didn't they go back and fix it. I'm more astonished that they just let the mistake go uncorrected than the fact they made it. The site seems designed for kids or young adults who woul get confused.
11,000 years of nul-G. Hah. I don't think so. Blobs of jelly would be the landing crew.
The government taxes all trips to Alpha Centauri 50%
Can we build a telescope to see thru the atmosphere of proxima b?
We have already. The James Webb telescope can do it!
It would have to be huge, and somehow identify what it's made of.
@@ericgolightly8450 so it's not possible? :(
is it necessary that a planet closer to its sun will be tidally locked?
Southern sky, you say? Fantastic! I live in the South. If I hit the equator, have I gone too far? It can't be THAT far, right? I might need some money for gas...
What about ion propulsion
Wasn't this Star System mentioned in Hitch-hikers Guide to the galaxy?
😂😂
Guys, oNe issue with these interstellar travel is that if it will take like 1000 generations to get to the nearest star. Do you make tombstone or burial place in the spacecraft or do you toss the body out of the spaceship? Either of the option is not a good one. I do not know what to do. Tell me the right thing to do.
There are a few ideas that scientists and science fiction writers have explored. Some propose cryopreservation, freezing bodies to preserve them until they can be buried or otherwise handled upon arrival. Another idea is creating a designated area on the spacecraft for respectful and secure storage of remains. Alternatively, some suggest the idea of launching remains into space, though this raises ethical and practical concerns.
We will be lucky if we get to Mars let alone the Alpha Centauri star system
My gut feeling is when we get there we'll find conditions aren't condusive to us living there. I think it's a wasted trip.
So we should be prepared for return trip?😅
I love Science FICTION
If my calculations are correct I could fly there and back before I wake up in the morning
Conservatively with 200 years away from going to Mars this is probably at best $500 to 700 years away
Why do they put wings on a spaceship?
If there is a gas giant in Alpha Centauri I think it should be called Polyphemus
Solar sail? How do you stop at alpha centauri ( where the trisolarans live lol)
The Jupiter 2 had the technology to reach Alpha Centauri in about 5 years. And that was in 1997.
Such giant spaceship 🚀 Must be build in space ...
It will be a colony ship...of many people ...
LIGHT YEARS is a striate line if you did that to get there you would of missed the system by the time you got there
YOUR ALREADY LOOKING AT WHERE IT WAS 4 YERS AGO BEFORE YOU START THE TRIP
Praksimma Sintoori?
People from that planet PROXIME CENTAURI B have already reached our planet Earth way bk 1961 to 1962.
While the cryosleep is not possible for adult humans at this time. Human embryos are easily frozen.!
One method would be to develop machinery than can raise a human from embryo to adult, while training them for the mission.
20 years before arrival a few dozen embryos could be awakened and raised to adulthood during fight!!.
This would eliminate the vast Quantity of food needed to be stored .. and solve a plethora of other problems would be solved!!
And the ship could carry tens of thousands of embryos in a relatively small space.
Do you think some type of computer / machinery to raise embryos to adulthood be developed with current technology??
What about ion drive engines? They were successfully used to visit an asteroid not too long ago. The trick was to use a propulsion type engine for the initial thrust and get it to a certain speed then switch to ion drive which starts out slow but increases speed as it goes along. Plus it gathers ions from the space around it and doesn't need refueling. I would imagine we would send artificial intelligence long before we would send human space Travelers there. If the artificial intelligence found anything that was of Interest and worthwhile then we might send humans later on. I think Alpha Centauri B and C could be more promising because their stars are like our sun. I really don't understand NASA's current obsession with red Dwarfs.
