- The Solar Gravitational Lens will Map Exoplanets. Seriously, there's a real plan to do just that. Using the Sun to gravitationally lens an exoplanet into an Einstein ring turns the Sun into the most powerful telescope in our solar system. But it's not science fiction. Plans are underway at NASA's Jet Propulsion Laboratory to send solar sails to the solar gravitational lens focus to make the first ever image of an exoplanet's surface, and do it within our lifetime!

This is why humanity is suffering. Stooges believe anything. Please go look up long distance infra-red photography. Where is the curve?
These images would take at least 40 years to get
Does this type of lensing render the “Terrascope” obsolete?
It still seems like you could only image planets that are only in a single line from sgl to the sun. How many planets could be in such a line? Won't they orbit off the line? How long would they stay in focus?
humans will never escape the solar system you wont even colonize another planet. Its cool seeing images from space but only Jesus will set you free. Science and technology will hit a dead end soon and all will bend to God and he will make himself known to all.
Man this is insane. I feel like someone realizing the potential of the transistor for the first time. I never thought we could actually image exoplanets in my lifetime.
Gravitational lenses are not a new idea. fifty years ago the book Protector used one.
Imagine using lensing to view light that's left earth in the distant past. If light bends and failsmto escape blackhole, then some light bends 180° back to source. Timetravel anybody?
@@geraldfrost4710 neither were transistors when the silicone transistor was invented.
Same!
This means that intelligent life out there within 1000 light years is probably using this method to watch us.
That is one of the most inspiring science based videos I've ever watched. Hopefully it gets more people fired up about what is over the horizon. Thanks for the great insight.
Wow, thank you so much!
I agree wet you on every word .
Hear, hear!!
I cant wait until we use one of these to figure out whats up with tabby's star.
And one of the most frustrating. They have been postponing James Webb for years now, imagine how by much this thing will be delayed. And when it's finally there after decades of delays and travel, all we'll get is blurry images of barren planets similar to Mars, the Moon, or cloudy ones like Jupiter, Saturn and Venus.
imagine doing all that and discovering the planet is a perfectly smooth colour like uranus XD
c blocked!
Uranus is not smooth. The "surface" we'd see would be constantly changing, but you could hypothetically apply the same data gathering methods in really high concentrations to get high resolution in shorter periods of time. You can still learn a lot. Plus these would not be set up to look at one object. Even if it were possible to look at only one area of the sky w/ out any rigorous intervention, that's a colossal waste of resources. Space telescope technologies are usually quite versatile in their missions, to get bang for buck.
@@atlas42185 Link a photo of uranus that shows any surface features
@@isbestlizard
There's been a misunderstanding. What I thought you meant was the apparent surface of Uranus not what lies below the clouds, if there is a solid surface. I don't think there's any practical way, given current human technology, to observe what's below. So when i said "surface" I was referring to uppermost visible layers of the atmosphere. Like any gas, the atmosphere of Uranus is anything but smooth. Gases will remain in constant turbulence unless energy stops being added to the system. We have only very low resolution photos of Uranus so it appears a smooth blue marble, but I don't think you can describe turbulent fluids as smooth. I guess that depends on how much variability in surface topography you're willing to accept before calling it "not smooth."
Imagine if it was all just a spec on the sensor
There's so much work that goes unnoticed by the general population. Thank you so much for explaining with high level of detail what the researches are doing right now!

God, I love those rocket scientists and astronomers:
They achieve the equivalent of taking a photo of a Seals whiskers in Antarctica. Out of Washington.
I think that may even be an understatement compared to this idea
It's more like looking at a blood cell at that distance. We have satillites that can pretty much do what you suggested already.
12000 km vs 100 lightyears. Let's just get handwavy and take 1 lightyear to be about 10 trillion km(10^13 km). A planet similar to earth has a diameter of about 10^4 km, so we are talking 10^15 vs 10^4 km. An absolutely insane comparison, 1:10^11.
Even using a scale model of earth as a 1 mm sphere, that distance is 100.000 km. Or 2.5 revolutions around the earth. For good measure, take a 3 mm dust speck and place it on the moon. Then detect that speck from earth, that's what we talk about!
Even in analogies like this, earth itself becomes too small to facilitate a scale model understanding! You almost need solar system level distances to provide an analogy for interstellar distances if you want any kind of toy shaped representation of celestial bodies together with distances between them....
That is one of the most complicated but yet most informative science videos I have ever watched (also not in my native language) I appreciate your effort and your very deep sense for detail and humor :) Keep going. I am looking forward for more content.
Wow, thanks! I'm so glad you enjoyed it!
@@LaunchPadAstronomy can't they search for applicable stars that already lense planets, we can observe millions if not billions of stars from our inner solar system, why bother to move to a position to use our own sun when we could use other suns if possible??

@@Nen_niN I love that quote too, i watched the movie about him.

@@Nen_niN
I threw away, without a stop,
My notion of time around the clock.
But it matters little, there's still a little,
A little time for ilusion.
Ilusion of not seeing,
This tick curtain in front of my being,
Hours pulling time from my hands.
It's my fault; The wind still blows,
The curtain rises,
My eyes? They don't.
I wrote this a few months ago, i was going through some hardships. Never shared it, i never liked the idea of translating it and making the rhyme disappear, but i do hope someone (if anyone) likes it.
That human beings have come up with an ingenious idea like this blows my mind and humbles me immensely. The collective imagination of all these scientists is inspiring.
Now imagine the capability of a Matrioshka brain and the civilization that would use it. Now imagine if some extraterrestrial civilization has already achieved this by now. The things they will be capable of...........I can't even begin to imagine. Humanity has been around for only 0.2-0.4 Million years. Human civilization, only for about 10,000 years. Imagine an alien civilization only 1 million years old. It would likely know of our existence today. Even if they are unable to reach us within this time, does not mean that they haven't already seen the night lights of Earth, declared us a threat and are redirecting their forces against us as you read. They might arrive in a couple of thousand years, and by that time, we will be aware of their existence (unless they hide their existence, assuming they can).
So the real question is this, if this mission succeeds and finds night lights on a planet relatively nearby (a few thousands of years of travel time by fusion technology), how would humanity, then, react? Immediately start preparing for defence? Probe further? Both? I envy the future humans who would get to partake in a planet-wide/system-wide discussion on such a system.
Now imagine, that what you're being told here: is idealistic bull sh!t. Just try to imagine, I know it must be hard, based on all the pseudo-science they presume.
@@matejmazur191 What "Psuedo-Science"?
el oh el.......
@@death_parade though I feel reluctant to even message you; nevertheless, I will humor you by saying that ignorance is the key to conventional science as it outright disregards and viciously attacks any possibility of a creator. If science, as it were, was a fair and unbiased practice, we as society, would have reached a near-utopian state. However our common enemy (Lucifer/iblis), has manipulated many in power through the power sin/lusts - works every time with carnal leaning mind. Their bodies overpower their morals (soul), their body's urge is too strong and their willpower is not enough to say no. You cannot trust individuals like this, because they have been made worse by evil. Nobody is born evil; that is fostered within a person. In conclusion, science disregards the now obvious and proven beyond reasonable doubt "spirit realm". The official acceptance of such, would lead to their undoing. Science is what they want science to be. Another trick.

Direct images of distant planets is literally the next holy grail.
Because none of us will live for any of the grail's beyond that.
No, such missions would be launched for dozens of Earth-like planet candidates to be checked out. It's the JWST mission of 2170 ...
This is absolutely incredible!! When you look back and wonder how the ancient scientists managed to get such a handle on reality and physics before any of our modern technology, you learn they were ingenious in working around their limitations, using ostensibly primitive tools. We are in but another phase of this; before we have more concrete ways of actually imaging planets, we are using our primitive workarounds with the aid of pure human ingenuity! Great video.
Thank you, and I quite agree it’s pretty impressive stuff!
Even if this takes another 250 years to arrive it's amazing to see how fast science and technology are progressing. This is incredible. Thanks for a great presentation. Scientists are awesome.
It will NOT take another 250 years this is present day technology.We'll get there faster with NTP,nuke rockets.
"Your friendly neighborhood astronomer" ?
*Closes the curtains*
With great resolving power comes great responsibility.
Surely Norman Osborn has the technology
Best astronomy video i have watched on youtube this year. Thanks bud!
Wow, thanks! I'm really flattered!
I agree!
This is fascinating! Thank you for this!It might not happen in our lifetimes, but is definitely something that will happen at some point in time.
We lived in a time period that allowed us to see surface of planets and their satellites in our Solar System with resolving power that wasn't even dreamed about 50-60 years ago. We have landed on Titan, Staturn's Moon! That is inspiring!
Yeah I'm 30 and don't see this happening in my lifetime. But unlike visiting these exoplanets themselves, this may be done in a century. So it's not as distant as a prospect.
I do not believe I've ever been this caught off guard by a video before. Bravo! The future is exciting!
Wait a second, this means THE ALIENS are watching my every move with their sneaky owl-like Supermassive Black Hole Gravitational Lenses!
Dont worry, depending on how far away these aliens are, we are still just a bunch of apes or even dimetrodons.
Yup, they're gonna find out who's naughty or nice
Well, when they receive the photons which are emitted (scattered) by you now...how should I say this....well, it won't be a problem for you anymore...
@@palfers1 All of the dimetrodons are nice
Viewing would not be realtime. They'd see deep into our past the further away they are. What'd be cool is capturing light from earth that has traveled out bent around a black hole or other massive object and returns giving us a glimpse of earth's distant past!
The technology and precision required to do this is so inspiring that we can do it.

@@karlharvymarx2650 Good, because defecation is our ultimate purpose. All living beings are just more complex way for universe to mix various materials into otherwise unlikely combinations, through never ending digestion and defecation cycles between countless living species.
@@6squall9 I've long thought defecation is evidence for the non-existence of God. Who in their right mind would design an anus and perianal hair that necessitates post-defecation cleanup. If I were designing a butt, I'd add an organ near the exit that encapsulates the poop in a biodegradable plastic bag, that would be intelligent design. But no, nature made us and cared so much she made us go around with poopy butts until we had to invent the bidet. Anyway, that's for making the Lion King Circle of Life play non-stop in my head.

This is fantastic.
James Webb was set back another 7 months this week so, no, I don't think I will see this come to fruition in my lifetime.
I've been waiting 60 years for a flying car so no, this isnt happening beyond studies to soak available funding.
F Janson there is a flying motorcycle now so you basically made it
That’s only because of the lack of vision & ineptitude of our politicians who can only see to the ends of their noses (terms)🙄‼️
Get Elon musk interested.. then it'll happen.
F Janson I think it was Elon Musk that said this, but it resonates with me as an “Ah ha!” moment.
He said helicopters are basically flying cars. Imagine a drone big enough to carry a person/people autonomously to a destination. Also there are some prototype flying cars, but you need an actual airport to takeoff and land, and there’s some assembly required every time you want to fly. I believe you need a pilots license as well for that.
There are so many cool ideas in this episode
There will be MAPS of exoplanets in my lifetime, that's incredible.
Forget maps, I’m thinking a hologram, or more realistically a rotating sphere you can hold in VR!
I am currently in the transition from CS to Astronomy/Astrophysics and seeing projects and ideas such as these are a huge inspiration for me as a potential contributor to these future accomplishments. Awesome video, I hope to see more in the future!
The more we learn it just seems like nature has created these puzzles for us to solve. it just all seems so perfect lol.

Did your heart skip a beat when Christian said there's a way to get there in 30 years?! : a few months to Pluto, passing Voyager in 7 years! Those sun vanes approaching the sun are some amazing tech concepts by themselves.
3:09 "instant light sail" hahaha, that cracked me up. Imagine you build something so great and it just sails away hahaha.
Wow! This video really gives us a hope. Enjoyed watching it! Nice job!
People told me 20 years ago this was so impossible that it would never become a reality. So I put it out of my mind. Silly me.
@Pouty MacPotatohead I choose cognitive dissonance in this specific case. Not about the tech, but more about to get this organized as a group.
So, overall in kinda think its doable enough (under my very optimistic assumption that all will be well social wise, my rationale says, meh.. I guess we still have some growing up to do)
And .. maybe the AI's (hey I can dream right) will get annoyed by us messing around slowly and inefficient, will devellop some kind of emotional bond like we have with pets or small children, and take the effort of helping us be more efficient and defuse silly behaviours that are baked into us because of historical reasons/evolution or even some brainfart moment of a creator if that is more ones' thing. Despite it being a burden for the AI's in a pragmatic sense. Maybe an general AI, or some of them are super interested in all kinds of stuff, including stories of origin. And there then are still around actually these "primates" that seem to have stewed their primodial soup, how awesome to study the subject creatures in their natural habitat,..if you are that curious and independant general AI that is..
So yeah tech and science and even resource (not talking about money) wise it can be done, practically and in a soceity context though ? ...
:)
And I want the Korona stuff sent away as far from earth as posssible, Im fed up with the current global debacle, regardless any metric.
Better to have the word regain its literal meaning of crown-like and let the crowns serve us for a bit, baking in the sun, providing some shade ;)
There is devide and conquer (great game btw from old haha) but there was also Solomon that did exactly the opposite -keep intact and save the situation-, and became synonymous with wisdom.
He wore a crown. Just sayin'
Im bored I guess, want to return to more normal things than the tubes.
Greetings.
@Pouty MacPotatohead yes.
There is nothing in current pysics or science in general from getting the project from the ground. And yes i think the bottleneck is a social one.
For starters, the low number of scientist engineers and other other critical people needed for such a insane complex project are currently not available.
Is that a tech issue or a social thing ? In my view more a social one. Sportpersons winning a game are national news.
The guys that finally cracked the bizarly difficult issue of the blue LED and ,all the implications and applications super quickly after that, ..uhm who were they again ? What country again..how long ago?
When I teached at a highschool in NL, the sciences department was tiny compared to other fields. When i used to ask students ,when they showed an obviously keen interest in the indepth idetails, and i also learned that many of these students were doing some really cool stuff 'just as a hobby' why they chose to study xyx and not any of the more beta science related things, most answered "it seems so difficult, and it takes a bit longer to finish and in the end I get paid less than by choosing this"
completely reasonbly and understandable.
A pity ? Maybe. Maybe we its overkill to have a whole section of society being in tech, i dont know. Im too biased to have an good idea. I do know that we quickly need lots of practical technicians as well as more and more people taking care of the retiring people. They need more medical personel and that medical person needs more effecient tools to deal with the workload.
Lost potential for those impossible projects, most certainly.
Combine that with much more effective fabrication and designing techniques and why is it so impossible tech wise ?
Will it take much effort and would it have setbacks and, well be sure of it. Any new way of doing stuff is bound to rough, and most stuff does not work the way you want. That is the standard. When doing a synthesis as a practical example, the first run even with a complete discription any experinentist does not expect it to work, too many dissappointments a person can handle right. But when it does work it is awesome. Let alone new stuff. And you "just" account for this low succes rate by having backup plan after backupplan and also have other groups doing similar research and keeping in touch and read until you fall asleep on the keyboard.
Tech is impossible until it is not..well sure. By definition. The same goes for anything.
I prefer tech is possible and doable when there are no intrinsic bottlenecks.
Need a wormhole for it ? Well.. that is a showstopper atm.. a huge swarm of small computers with low power consumption and a range of sensors and transmittors and actuators and updateable software and redundancy .. well put extra mylar gold foil to the gazzilion of phones were already churning out by the billions and youre done. Not really, but even gallium based more rubust chips are currently beginning to appear.
It is an huge undertaking, but no not impossible. And 40 years in oldschool style is not many itterations if an idea. Now 40 can be many itterations. Most will not pan exactly, who cares. If the end results are how to practially use solar sails and swarm tech and in that miniature formfactor even without self assembly, that does count as a win in my book.
We said the same about electricity or computer for the masses. Impossible and pointless. Pointless i could even find myself agreeing with. Impossible.. nah. A pain in the neck sometimes yeah..
:) tech has been around as long as homo sapiens has been around, it is part of us and vice versa.
Dealing with the increased pace of tech after tech is straining us i think, that couples back to my conversationw with these students, they often did want to start a business for example but were too hesitant to go into depth when actually they secretly wanted to. Science was not that polular with students during that time, but maybe it has changed. I dont know.

Tbh I do understand these people. Detecting exoplanets at all is insanity in and of itself, let alone directly imaging them. If you know how the radius of a planet compares to the distance to that planet, any notion of detecting it just seems utterly absurd.
Worse than detecting a fly in New York is for me, and I live in the Netherlands. But they managed to do it. Imaging is a whole new ball game altogether, and the fact you could do that with a cunning trick involving gravitational lensing is absolutely awesome! I never even imagined this being possible even before watching this vid.

Oh, and I assume we can also use this lensing technique to lens other wavelengths of the electromagnetic spectrum? Is there a practical way to do this with say, radiowaves, IR, N-IR etc?
I do also like the occasional humorous remarks in your videos :)
Thanks! In principle this will lens all wavelengths by the same amount. However, the corona becomes more of a problem at longer wavelengths so you'd need to back up further for IR and longer. The 650 AU distance is calculated based on λ ~ 1µm, which keeps it close to near-IR/optical.
Launch Pad Astronomy So if equipped with multiple instruments the sats can continue imaging the target after running out of visible light...? Awesome thought.
Your presentation is inspiring and provides a lot of hope that this project can start moving soon. Very exciting.
Thank you for the program!
From what I understand, gravitational lenzing can also be done with other celestial objects such as the planet earth with its atmosphere. You wouldn't have to be as far out and gets rid of many of the problems associated with looking directly at the sun. I hear that of course its much less powerful then using the sun, but a 500X increase is much better then the current system with a 0 increase not doing any lenzing. Cool worlds on youtube goes into it, wonder if there are any projects in the works exploring other options for lenzing going on? Great Vid, -Cheers
That’s actually what bothers me too. Is it possible to make small version of such telescope? What are the limitations? What results such ‘planetary-lens’ telescope would give us? What it would cost? Sounds like it would be very reasonable milestone before trying a solar version.
@@maximmakarov3855 Ah yes, have picked up a little more info on this subject, sense that last post. I have seen an in-depth proposal concerning a first attempt on a sun based telescope, and lets just say it seems way out of reach/current tech wise. Just ridiculous cost and time to reach the needed distance etc. On a brighter note though i have also seen a few new videos that they have been successful using our current telescopes to use distant (black holes, stars) with some success and are working on refining it and making some progress with new methods (software, and hardware to correct distortions). Exciting times I must say... anyway best of luck. -Cheers
@@mikein60fpstwitch.tvaliber73 exciting times indeed! Thanks for your reply!
one of the most interesting videos i have seen for many years... thank you
Glad you enjoyed it!
Every 10-15 seconds, I was like... "wow..." over and over repeating it... 😲
A well researched video, well done. I just subscribed.
35 years? I am way to impatient i wanna know Tomorrow!
So far, the most interesting video about space voyage I've watched. Thanks for the insight...hoping to see more.
One of the best science videos I’ve ever seen, subscribed after only one video. Standing ovation level appreciation.
Wow, thanks! I'm happy to have you along for the ride!
Within my, our lifetimes *facepalps
Face polyps?! yikes go get that checked out, Homie:P
I would love to see this become a reality, what a truly inspiring vision for the future. Sadly, I suspect we won't live to see this mission take place. While all the individual technologies might exist or be in development combining them all together in one expensive, long and complicated mission will take a really long time.
It's been years since I watched an inspiring video like this one. Thank you so much!!
2:15 I love the subtle nod at the comedy of the humane and unscientific concept in the common phrase " within your lifetime"
20:15 I was extremely surprised that the focus line always starts at 550 AU, regardless of how distant the target is. Is that simply because any potential target for this method is far enough away to effectively be "at infinity", and the real difference in where focus is is so small as to be irrelevant, or is there some more interesting reason behind this?
Oh, and thanks for the great video! About halfway in, I was feeling "this doesn't sound feasible at all" but that really turned around during the second half! Go team space! 🤩
Great question. Also i wonder how much faster nuclear propulsion can practically be than solar sails if any.
Wow! Very ambitious but really it's inevitable. Although the cost will be high, accessing the information held in the sun's Einstein ring will be transformative for astronomy. This is the ultimate telescope.
Agreed it's the most ambitious proposal I've seen so far. One of the many things I didn't get to talk about is that it could actually be affordable given mass production of off the shelf technologies and economies of scale. I don't think it's been fully costed out as of Phase II but my understanding is that avoiding the flagship mission approach could save several billion dollars.
@@LaunchPadAstronomy is there any possibility for international collaboration? Might make sense for a project of this magnitude. But I tend to think it's doable in the next 20-30 years if we prioritize it like with the original Apollo missions in the 1960's. This is a prestige project.
@@drinkxyz This project idea puts together a lot of technologies we've been working on and various entities (NASA, DARPA, NRO, ect. in the US alone) already have vested interest in. That will help a lot politically.
Actual money/resources wise... It is certainly doable with current launch technology, but would greatly benefit from in-orbit (or perhaps lunar) manufacturing infrastructure. That is the next big step we need, because it will make a lot of possible thing actually doable. I think that is probably the real aim of Artemis, not a "stepping stone to Mars" (because trying to live on Mars is a really dumb thing to do), but a start on our factories and shipyards in space. This exoplanet imaging project would be a much more worthy flagship project / goal.
The quality of this video is outstanding, brilliantly explained, very interesting. Subscribed
I was so blown away by this video that I had to subscribe to your channel. Putting this together must have taken a huge amount of effort and time. Thank you!
Wow, thank you Dan! It was my biggest video to date so I’m glad you appreciated it!
I think that next 20 years we will discover more about Cosmos.
Hey Christian! another great video, always wonderful to wake up early to your smiling face! cheers man
oh and I see that steal your face n the background lol
Thanks man, I really appreciate it!
Extremely well researched and informative, delivered in a clear, concise and inspirational manner. +1 sub.
Thank you, and I'm glad to have you along for the ride!
What a fascinating and well-produced video. Thank you!
Glad you enjoyed it!
This is all mind blowing....thank you sir for making this information available. Shout out also to the scientists that strive to make us understand the world and universe we live in. Much appreciate.
Thanks, I really appreciate it. And yeah, they're some amazing clever folks!
Sunday Aito and to those that popularise said good science here on YT so us plebs can try and get a handle on it. Cosmology is humanities greatest gift to itself.
Seems a bit too ambitious to me. I like the idea though.
It is. Currently the only basic studies are going on.
Ambition is what drives the frontier of science and technology. We couldn't possibly be too ambitious in my opinion.
@@etzie1728 yes with imminent economical crisis, these thing won't fly well until decades or a century in the future.
Too ambitious? Ya, like imagining vehicles that move without horses, devices to talk to people across an ocean, etc.
If possible it's possible it has to be done...!
Money and costs should be irrelevant...
This is incredible. Thank you for the video.
Your videos are awesome! Explaining in simple terms how very complex space missions (will) work is a state of the art. Thank you!
"My... err... our lifetime". lol. I can relate. I want to see it too, damn it!
this is truly a "physics hack"!
Indeed it is. It would be the first "application" of gravitational lensing :)
This is truly intriguing. Let's go!
Extremely well presented and interesting voice tone, good graphics also! well done!
The Total Perspective Vortex!
"Still not to scale" I love people with humor
Compliments for this video, especially the information on the status of these technologies. Thanks.
It's my pleasure, and I'm so glad you enjoyed it!
Just found your channel! Very nice graphics, and I for once understood everything👏🏼😁
Glad to hear that and I'm happy to have you along for the ride!
So freakin' cool! As a SLIGHTLY above average intelligent person, I love and appreciate truly intelligent peoples' work. I'm not smart enough to do it... but I'm smart enough to gain pleasure, from the beauty of their work! :-D
I wish my dad talked like this... this is less threatening.
Love your channel! Great mixture of well detailed content and cozy infotainment - no one wants to deconvolve this!
Thank you so much!
The quality of this channel is 10/10. Amazing info + visuals
Thank you so much!
30 years?
I'll be too old and too busy yelling at kids to get off my lawn.
Use the Clint method for that.
Imagine having the possibility to spy on our new interstellar neighbors
@@thenasadude6878 Get off my lawn!!
As scientists learned of the sheer scale of the challenge of imaging exoplanets directly, they began to find effective shortcuts which reduce the required financial investment and technology level to conduct such imaging.
This lead to the "wobble technique" and transit spectroscopy.
Each time we take such a shortcut, the nature of the technique usually necessarily limits the number of detectable objects.
Transit spectroscopy requires us to view the relevant star system at the correct angle by chance, for example.
The solar lens plan limits us in terms of requiring a mission for each target of observation, and having only one magnification level.
I find all this oddly satisfying.
In these, our self-destructive days of youth, we dance with death by misadventure, and yet, are gifted with the chance of a preview of the unimaginable knowledge and opportunity that awaits us.
If only we survive.
I believe that technology is a filter which selects for overcautiousness.
The species that take our laissez-faire attitude to technology inevitably destroy themselves too soon to colonise space on any noticeable scale.
The species that treat technology with the reverent respect it requires, either do not make the necessary technological leaps for space colonisation, or go to great lengths to conceal themselves.
Very interesting comment! The grand vision and the actual implementation in such scientific projects are often far apart due to the overall priorities of human societies . Some of this has to do with the stepchild position of science in society. We accept its gifts but most don't understand science and therefore the value of investing more in such projects is not appreciated. This also hampers best decision making processes since the objective reality of scientific method is not understood or given the weight it deserves. This may indeed be our demise. Possibly there are other civilizations out there who value science more and therefore understand the dangers better and navigate around them to mature and survive the great filter. Science teaches to observe and then judge the meaning or the rules governing. In some sense this is a prudent, cautious or humble approach to understanding the universe. Perhaps even as we contemplate building such a telescope others observe us with one of their own, monitoring our progress in fits and starts, taking bets on how long we will survive ...
This has got to be one of the BEST Sience Videos I have ever seen!!! You should be given a special award for this superb video!!! Didn’t have to think twice to subscribe.... I love this extremely creative idea, it’s genius!!!!
Wow, thanks! And I'm happy to have you along for the ride!
Amazing stuff, thanks! I work on the E-sail and we are working on a SGL mission with it!
