"A long time ago, in a galaxy far, far away..." there was a type 3 civilization.
DarKool81 that met a .7 civilization..........The End
That met a category 10 Kaiju

If we live in an open Universe, the size of the universe is infinite. Therefore, it doesn't make any sense to talk about the total number of alien civilizations in the entire universe. It only makes sense to talk about the density of alien civilizations. That is, number of civilizations per galaxy, for example.
Eugene Khutoryansky The universe has no edge but it is finite, space time is curved
Leonard Greenpaw What you are referring to is the closed Universe model, which is also a possibility.
***** The open Universe model is one of the possibilities in cosmology, and in this model the universe can be both infinite and expanding simultaneously.
Eugene Khutoryansky They probably meant observable universe.
Dan Albl No, I mean the entire universe. Think of an open universe as an infinite number of points along an infinite line. You can have the distance between each point and its two neighboring points increase with time. In this case, the Universe would be infinite, and yet the distance between the neighboring galaxies would still be increasing with time.
I really appreciate the separation of each microphone between the left and right channels. Sounds great!
Keels Boswell really? I hated that
Johny Bänger Do you have good-quality headphones?
Keels Boswell I have
I agree with Banger here.
Keels Boswell I have too but it is really annoying! (Audio Technica ATH-M50)
What if we are the most advanced civilization in the Universe? Everything is possible.
Could be true , so many questions and answers ...
+Ozzy Considering our very young age, I Highly doubt that.
+ty hamilton
Despite there being a number of at least self aware species all across our planet (dolphins, elephants, a few variants of great apes, etc), we're the only one to have developed technology of any kind.
Aliens will NOT be able to explore the universe, or even reach our level of tech unless they're of these three things:
1) have the ability to construct; they have limbs, or whatever that is needed to manipulate tools or resources
2) have a desire to even build tools to help them in the first place
3) have a desire to explore, like us.
If this is not the case, and the aliens are kind of lame, they might end up never actually leaving their world until they are either killed off by a random asteroid, or by overpopulation.
Even if they did manage to get into space, what's to say that they'd build anything more advanced than their most basic constructions? If anything, they might just stop trying when they figured that nothing could go faster than the speed of light (a lot of people these days here at home seem all that uninterested in proclaimed 'ftl drives,' since there is supposedly no real feasible way for them to exist).
If FTL really is impossible, I seriously doubt that anyone would get anywhere fast, ever.
Think how far we have come in such a short period of time. Now imagine a civilization(other then giant crystal lol) Working at it for a million, a hundred million, a billion years. The only thing impossible , is that such a thing as impossible exists. :)
+Ozzy I really don't think that's possible.
Lol when you said Dyson sphere I first thought of the vacuum cleaner... that is actually a clever name for their product
0.7,lol we are so bad . . .
RRGeada I'd give us a 10 on the F'ed up Scale! :)
Hey I gotta say, it's higher than I expected.
RRGeada Hey... like they said we're only 50,000 years in. Just babies lol
babies with very bad habits
***** not everybody have that instinct... look at those fighting because something that no one knows (wars), look at those killing people do you think they care in doing better??
Wouldn't a planet size space station collapse under its own gravity if it wasn't a sphere?
***** My thought , exactly! No way, it would not. Any mega project such as a planet-sized space station will have to take into account its own gravity.
Jacob K you guys are thinking inside the box man. We have no idea what aliens could do
***** maybe they would have some super material to sustain the stations weight ?
***** You simply start by polarizing the hull plating thus reinforcing the structural integrity field. :P
***** it depends on size of the planet/space station.
You'd really need to build a very large space station to generate enough gravity to collapse on itself. A space station size of Earth won't have enough mass to collapse on itself, it'll be barely one third the mass of earth generating half of Earth's gravity.
Keep these podcasts/videos coming!
If your interested in the fermi paradox: in a nutshell made two really really good videos about that topic.
Yes they did good channel
Johny Bänger femi paradox ... almost sounds like it's about how feminazis don't even agree on their own made up numbers or something
Qawn LELEK
It's the Fermi paradox, named after scientist named Enrico Fermi.. And not Femi..
Tamajit Das Woops, typo. Sorry.
Qawn LELEK Well, i hope you only mean feminazis and not the feminist movement.
Love this video, almost cried , I really hope we find life on another planet. This is something I dreamed about since I was a little kid. I always looked up at the sky an thought is somebody up their 😂😂😂😂. Thank-you for a great video.
I love seeing Trace geek out.
OMG I needed to hear this! These have been my thoughts exactly on alien life.
What's the scale called where their are type 1, type, and type 3 civilizations?
Please let me mix your audio. I could fix those panning issues in a moment and touch up the eq, peaks, and compression a bit. From Philadelphia, I've interned (and have a residency) at some famous studios since school ended, and am now trying to get all of the work I can. I would do it for free, and I can certainly handle it. I love the shows - heard Michio Kaku touch on this a few years back. Great stuff.
This video was kinda off topic but damn, learned a lot of useful material! :D
Stereo sound to the max.
GREAT VID! THANKS TRACE!
Regarding Dyson Sphere detection....
How could you detect infrared emitted from it?
Presumably the Sphere would be designed to capture ALL forms of energy being emitted from the star, so that would include heat energy. The exterior side of the sphere would be ice cold, because the heat has been absorbed before reaching the exterior.
Hey Trace! maybe you can make a video about manipulation of gravity? if you want I can share certain information on questions you make for part of the video :)? Anyways what i believe do to experiments I am trying to do hypothesis and equations i made using superconducting material that it is not possible to create anti gravity but .. you can direct the propagation of gravity in other words directing the propagation of gravitons and with equations I have made in hypothesis the normal propagation of gravitons is 64C and it is possible to attract gravitons to one area through certain frequencies and rotations of the superconductor and in other ways discharge these gravitons to compress and decompress space RECURSIVELY because gravity affects gravity in a recursive way
not only that but I believe that if someone can achieve the compression and decompression of space which essensially is attracting and pushing away gravitons effectively distorting space then someone can create a device that is sensitive to gravity and sensative to these distortions if you have a device sensitive enough to the distortions you can effectively map any part of the parsec we are in
and I am trying to work on making a device that effectively creates a gravity distortion to bring an object toward it or move it away and notice im not saying push away because gravity/gravitons is the thing that tells matter which way to move
and I will be doing an experiment very soon that is based off work and equations i made (based off machs principle; the principle of inertia) and designs that fit within the law of relativity I checked it over with my professors and collegues multiple times we believe that the experiement that is to be done will most likely work and is a 90 percent chance of success and if not we do believe that we are still on to something if it works it could effectively compress and decompress space around an object affecting the space around it in a recursive manner and something that could detect the recursive distortions so hopefully if that is done we can measure the strength of a distortion that came across passing by earth determine its size and its width with predictions of what a warp drive is capable of distorting and then come up with equations from the data that will allow us to measure the distance from the point of origin where the distortion occured in space where we cant see with telescopes and effectively then predict how much compression and decompression of space itself it would take to initiate a warp drive by measuring the initial distortion of gravitons/space when first understanding the original device me and my team is trying to create that will attract and push away gravitons and again that if achieved even on a small scale will effectively compress and decompress space then can be scaled up to the be fit on a ship and with the compression and decompression of space there would be no need for rockets to get into space. what we the phenomon that we are trying to create is a transient mass shift and the device can achieve a transient mass shift of 24% when it reaches a 100% shift it can begin to direct the propagation of atoms and molecules upwards removing all effective atmospheric pressure above the object when that atmospheric pressure is 0 and the bottom of the craft is 8 square feet for example at sea level there will be 1,411.2 pounds of force applied onto the craft itself from the bottom and here is what is nice if you can comperes or decompress space in a region you can counter the effect of inertia if inertia is caused by gravity then pulse it at the persons body so if there is a 200 pound male on the craft which has no fuel and only energy being used then he will be accelerated into space at a speed of 38,758.4 feet per second from the force at and near sea level without his body taking stress because the device will pulse the gravitons at him in a specific direction creating a transient mass shift equal and oppisite to the shift applied from the gravity of earth
if you have a question of what a transient mass shift is , think of a physical mass shift when someone pushes you or when you are pressing down with your pencil on a paper that is a physical mass shift but a transient mass shift is a shift from a magnetic field or from gravity and so the person will have zero or near zero g-force applied onto his body even accelerating at near that speed in a second and reaching escape velocity without fuel needed an atmospheric drive which directs the propagation of gravity upwards which in turn directs the propagation of the atoms upwards so they "fall" towards the sky and then use the atmospheric pressure below the object to propel it into space. and then when getting into space the object can rapidly compress space infront of it stopping it from moving forward and then slowly dial down the energy used to attract the gravitons allowing the gravity to flow back into the void when reaching near the ISS or the moon
we predict that a drive that is slower than light speed can be near a celestial mass and move around but if the craft is to be initiate a faster than light travel then it has to exit the solar system first and then go out a bit even farther away from the solar system before initiating a faster than light drive because the distortion of space and gravitons will be so massive that if its near a celestial mass it could possibly tear a planet apart entirely and if you are about 1 million kilometers away from a celestial mass traveling near the speed of light you might effect the planets orbit around its parent star...not good at all even if its a few inches and so as you get closer to a celestial mass the speed has to slow down but it most likely will be safe to initiate a drive at 20% the speed of light after you pass twice the distance between a planet and its moon/moons and as you get farther away the drive can increase the percentage of speed and when exiting the solar system then a faster than light drive can be activated... of course .-. this will only be possible if the few experiments we are doing now work.. which is tedious at times but fun to work with my friends and professors :) if the device works then we predict about 2 years for an atmospheric drive to be made 10-15 years for a sub luminal drive to be made and how ever long it takes scientists to figure out fusion or contain an antimatter reaction to sustain an FTL drive and for any aliens that have a warp drive they can most definately see almost immediately someone/something distorted space and pinpoint the origin of the distortion and follow the following distorion it will be like you lit a massive beacon
and when we figure out one day in the far future how to create a jump drive to jump from one place to another then we can have beacons which create massive spacial distortions which will be like a beacon for massive ships to jump onto and the ships will of course be shielded from the distortion effects because they can create it so they will be fine just imagine that... party A lights a beacon and party B initiates a warp jump and appears a few hundred kilometers off the bow of the beacon xD
One question. What i the time lord civilization rated?
The videos aren't viewable on mobile! Please change the left and right separation.
would it make sense to say that we are looking for ourselves, like is that a number in the statistic ?
How to start a war
1. Talk about religion
2. Wait.........
What about the Giant void 6-10billion light years away and 1billion light years across, could that be a type 3 civilization covering many galaxy's with Thier Dyson spheres, since we can't see the stars would it not look like a void to us ?
What happened to the episode with why we need to move to mars?? I was watching it then it stopped and I could not find it off of youtube anymore. conspiracy '0'
This is pretty cool and fun to ponder.
I read somewhere that the universe is so vast, that there is a chance that somewhere, life evolved to be identical to us.
The answer to this episode could live in your other episode on stopping light...maybe they communicate and travel in ways we are unable to detect
The aliens came here, saw our religious broadcasts and decided we were all insane, so they put up a quarantine in case we were contagious.
Interstellar travelling: Warp-drive! Please talk about that's possibilities!
And about the film Interstellar! :D
It's a massive topic
So what's in between solar systems and galaxies? Voyager 1 is outside our solar system, but what is that space in between called and is there anything like astroids, comets... planets, or is it just empty darkness?
Guiseppe Montenegro its called space. space is whats inbetween them.
That is an awesome Noble Gas shirt, Trace.
I have a question, What exactly are processed foods? What does it mean if something is processed?
You know you're a true Dnews/Test Tube fan if you watch this channel.
I think considering the number of potential happy coincidences that you need to allow multicellular and intelligent life to appear, and the amount of time required statistically for some of them to occur, we might also be one of the first technological civilizations in the galaxy, or even in the universe, give or take a few thousands of years.
I'm not sure type 2 or 3 civilizations would bother with radio communication. It's just far too slow. Are there any studies of faster/efficient transmission technologies? Or at least studies/discussionout possible methods aliens might use to communicate. I know there's the laser one, but since it's light, one would assume we'd run into to time delay issues. Love the channel!!
Protoss and zerg bio-signatures can be found in a place called the Koprulu Sector, which is about 6000 lightyears away from Earth.
These episodes are making me really want to watch some Star Trek.
I love this channel!
I've got so many questions but I'll try to cover like 3 or so
1. How is it possible for the sun to burn when there is no oxygen in space and how the heck can they be able to consume the energy of the sun
2.they say the universe is infinite maybe it isn't I mean they haven't made telescopes to see long enough maybe there is something or it is round or idk
3.if they say the universe expands where does it expand to I mean like it grows but where does it grow
the fuck have I been smoking the last time xD
arber beqa the sun uses nuclear fusion to produce energy. It’s not like a fire lol
I am sad because I will never be able to meet aliens or go to space and experience all of this at the rate we are going now. :(
MAYBE: When a civilization learns to harvest vacuum energy (or some other abundant energy of that sort) their simulations become so detailed that the civilization goes virtual (because it's much more fun to create a universe than to explore an existing one) and it _alienates_ itself and goes byebye. Maybe there are giant computers floating in the middle of space, trying to stay away from novas and stuff...
Do a week on dinosaurs like is it possible to use genetic modification with present animals to make animals from the past? Or can we de-evolve birds into dinosaurs
we need to develope or evolve to communicate telepathically. or build something like that thing from the movie contact
TestTube News you guys always have good stuff, but you gotta do something about the volume of your videos. The volume is too low.
The Death Star - though called "space station" is actually a giant starship!
A Dyson sphere can actually be many of small mechanics surrounding a star absorbing its energy, an example of size would be a multitude of satellites. It is a newly created idea that it is a "Star trek/star wars" machine.
The original concept of a dyson sphere was actually misinterpreted by star trek. It was more of a cloud of satellites in several orbits. Much easier to build than a single solid shell.
Let me present an hypothesis. That the universe itself is a living organism, in which different galaxies try to produce life of their own, in their own way, so as to produce the most intelligent life form as quickly as possible, on all possible planets of different start systems, so they can quickly build type 3 civilizations and ultimately rule the universe.
Silly suggestion but the aliens could look somewhat like us. Its been done in media like Doctor Who (TimeLord) or Asobi no iku yo (Cat planet cuties: Catians). As explored in both some life forms may be hostile whereas, like in the case of Asobi no iku yo, some may want to trade and form relations with us. Both could be possible.
Good stuff
The sound was not balanced for the physicist, I was hearing him from the left speaker and it was really knowing hard to listen lol, but good subject!
Given that you said the galaxy is 100,000 light years across then if there are any advanced alien races in the galaxy they would have to be technical for less than 100,000 years or we would have heard them if they discovered radio.
I watched this one video that had said we actually have received a transmission from another civilization but took years to decode cause it was a message within mathematics and once they had actually decoded it they learned it was a sos message from another civilization asking for help. They said that the civilization was just about advanced as ours having limited space travel capabilities. They said there was widespread famine and death and had no means to evacuate the remaining population and that the crisis was of there own doing. The ex-soviet who was head of some space organization said that the rest was confidential and that the crisis that the civilization was within could had possibly been caused by a nuclear war. He also added that when they sent the message sabertooth tigers were still roaming the Earth.
It is very hard for alien life to come in contact with Us. The universe is just huge. To get to a civilization Type 3 it would take us decades! The universe is pretty old and we are quite young as a species if an alien species has already got to the Type 3 civilization , they might know the existance of earth and humans but might not want to contact us in order for humans to be able to continue their life cycle.
Type 1 is a global civilization shopping for planets in its immediate neighborhood. We're at the premises of becoming one. The internet is actually an example of type 1 technology: A type 1 communications and information system.
Trace in my right ear, Ian in my left ear. Next time make the tracks mono! 😅
Awesome!
I never completely understood the concept of Dyson sphere, as in, of we put a giant bak around the sun, where will we, rest of plants and animals life get their sunlight from?
i believe it was more of, consuming energy directly from sun without letting any waste away, and transmit it to earth. I dont think living that close to sun would be a good idea. Priyanka chopra is already too hot!
Star Trek's Prime Directive is a very good reasoning.
god i love this channel
They had one good look at us and decided they didn't want anything to do with us. Honestly, I understand them.
this video made my feel like an ant trying to scream to a titanosaur
"you're not even type 1 bro..." ahahaha
i feel like they have talked about this same topic like 5 times before
my question: if a type2 civilization can harness the energy of a star would a successful hydrogen fusion machine make humanity a type 2 since we essentially created a star
We have found them. 1. Just look up at the night sky and do the math (Drake equation). 2. If this doesn't work for you then check out SETI and check out how hard it is to decode wireless data. The amount of transmissions that we've been picking up for years are truly massive. Decoding these transmissions would be difficult even if they were intentionally sending them straight at our receiver. So instead we've been looking for obvious signals that would likely only be transmitted by a similar technologically advanced civilization as our own (triplets and gaussians). 3. More than 90% of the universe can only be seen as the shadow of the gravimetric fields of dark matter and energy.
The universe is full of life we have not seen: we cannot see it yet, or cannot interpret what we are seeing.
But if there are planets that have existed since the beginning of The Big Bang shouldn´t their sun be dead by now? But maybe if they are a type 3 civilization they probably have figured out how to travel to other planets and galaxies. Because we have only "used" half of the lifetime of our sun so we have time on us to figure out how to travel to other galaxies.
yeah i mean having hands with fingers and thumbs does help in making inventions. kind of hard to make a car with fins
How do you know we haven't found aliens in our present or past?
NitroAgent 64 Well, if we had "found" aliens in our present or past, we would know about it. Finding implies the knowledge of something, right?
Unless you're thinking of the conspiracies. But that wouldn't be a scientific way of thinking about this.
NitroAgent 64 Whats to stop the government from hiding information.
What about a type 4 civilization? *mind blown*
I think maybe they're probably too shy around Earthlings now. I do predict that at some point they might be on their way to earth to announce all the mistakes mankind has made through the years, decades and centuries and what we can do to fix them.
There is the distinct possibility that FTL travel is actually unattainable.
Isn't nuclear fusion harnessing the power of the sun sense that is what runs the sun so wouldn't that mean we could jump from a .7 to a 2 with that tech sense we are getting closer and closer to making a nuclear fusion reactor
Once we hit type one ... Would other civilizations then recognize us?
I mean, I doubt it. What we find really advanced could be really stupid to others. Our vision of type 3 could be their vision of 0.1
+Thraxus TheAwesomeness yeah, they could consider time travelling back in time and harnessing the power of the universe type 0.0001 for all we know. They may even know how to break laws of conservation of energy and matter.
There aren't many advantages to being a naturally evolved meat creature when it comes to star-hopping. IMHO any entities that decide to leave home will probably be entirely engineered for the job.
What would be really interesting is if aliens could somehow figure out how to construct themselves at a great distance without leaving home. For example, sending powerful pulses of laser light into a distant atmosphere, generating a particular molecule that could then respond to another pulse, eventually building a system complex enough to begin processing data and replicating the senders, or at least constructing sensors and transmitters.
Another likely mode of travel would be nano-scale devices traveling close to light speed. Perhaps the makers would have figured out a method of communication that's instantaneous, and could blast these probes all over the place and receive a constant flow of data. We'd miss them as they passed by, but they'd see us.
Maybe our next level-up will reveal what we're now blind to. I'll leave that to our offspring, the AIs.
Final thought: I think the idea of aliens using stars for power doesn't make much sense. Space is expanding rapidly and increasingly -- surely there will be a way to tap into this energy source, such that the aliens could siphon vacuum energy in unlimited quantities and remain almost as dark as a lonely singularity.
Type 4? Consume energy from the whole universe?
I would say type four would probably be harnessing the all the energy of the local group.
Maybe using a sphere to collect energy is not the best way? There may be something better--different.
This guy knows more than he's telling. He probably knew about the "megastructure star" while doing this interview.
Simply put, these alien civilisations probably exist but are too far away for us to feasibly contact in a short amount of time. Even if there were thousands of advanced civilisations in just our own universe there's still little chance that any of them are very close to us physically.
If we've only been listening for the last 50 years wouldn't it be fair to assume that there are no alien life forms at the same stage as us within a distance of 50 light years.
We have found aliens, just play.. basically any video game ever.
I was about to say there's none in Assassin's Creed, but then I realized there are.
Theirs other galaxies out their in space and it must be alien life their to
I'm so nerdy for alien stuff O.o
the majority of life on our planet exists beneath the surface it could be that may be where most life exists everywhere else
What if black holes are the 'Dyson spheres'? Sucking up all the energy from the galaxy.
message to whoever is mixing the audio on this .. the left and right are uncomfortably pand to far apart
Wouldn't a civilization that could harness energy from a star sacking out all of its energy; then cause the star to collapse into a singularity creating a black hole? Which would be half cool and half EXTREMELY dangerous.?
I look forward to meeting our alien neighbors
I look forward to seeing Trace wearing the same shirt tomorrow.
I wonder if they've seen us and been like 'Xbox one is so 30,000 years ago'
Because we're always expecting them to look like us and not like some sort of parasite or strange creature
0:30 "They should be talking to us"
That's a *completely* *absurd* assumption.
Any advanced civilization capable of long distance space travel has moved beyond radio waves as a means of communication as the laws of physics make it impractical as a means of communication across such long distances. We can listen for radio frequencies until the end of the time and the best we're ever going to get is a transmission from a very young civilization like ourselves. Any species that can travel a million light years though space has found a way to not have to wait a million years for a data transmission. We're not listening in the right place and we're probably unable to even if we wanted to. With our current knowledge the only means of instant communication across such vast distances seems to be in the process of quantum entanglement.
Sorry to burst their bubble but type 3 do not exist. The project that was being done found no such signature. :(
Pulling energy... What is this a dragon ball spirit bomb?
4:31 & 4:35 omg yes! Lol, that's similar to what I had in mind. The Official Alien Correspondence Committee (TOACC) is just disgusted with us, the new alien race and is ignoring us.
Why are we so worried about space and aliens and we don't even know what is going on at the bottom of the sea
They are already here people. They were here way before we were.
wait wait wait ..what if aliens were once humans but then expanded in there galaxy and evolved like that (with big eyes and all that)
so solar powered doesn't make us type 1? in a realistic manner
