One day trillions of year from now the last red dwarf will flicker out of existence leaving a completely dark universe filled with evenly spread out atoms.
The video implies that no new stars are being made in order for all the stars to burn out. But aren't new stars being formed in nebulas and the universe is increasing in size. So how will all the stars burn out?
Eventually, the gas that forms new stars will be exhausted or so thinly spread out that new stars cannot form. In the Milky Way, for example, only about 10% of the original star-forming material remains. The increase in the size of the Universe merely stretches the distance between galaxies and has no bearing on star formation.
@TeHTwist97 In 5 billion years the sun would be a red giant you know? And why are you asking this question? The sun has no solid surface so what would there be to land on?
Great movie as always. Your movies are very informative. I also really like your voice, Imo your vids are one of the best if not the best space videos on YT.
This is so fascinating, I myself dream to become an astronomer and study the vast and fascinating universe. I alos dreamed of finding extraterrestrial life when I become an astronomer :D
I really appreciated this video and the effort you put into this video, great narrating and very good quality. It reminds me of Cosmos and that of course is saying a lot. Not to say I don't appreciate all your other videos too!! Great channel, my best source for space news.
Another great video. A question though: why would red dwarves be the last thing left burning in the sky? If they are producing helium, couldn't Helium stars form with the helium created?
The helium produced is bound up inside the star -- red dwarf stars don't explode, so there is no way for the helium to be dispersed into space to form new stars.
So there is hope for mankind! In fact we can all become GODS and have our own Red Dwarf and we can live for a trillion years or maybe more. Of course to become such a GOD you have to firstly become an athiest. Then you advance science, an athiest's tool kit., and become physically immortal, like Dr. Who. Believers in GOD must, of course, DIE after say 3 score & ten = 70. Ha Ha Ha! Or the sooner the better, for them - and we athiests. Ha Ha Ha..
You and Einsten seem to have thought the same thing....insofar as the Universe being static. Indeed now we know its a much more dynamic place than we ever dared imagine..... Get use to the idea Tony and stop repeating yourself..... It's NOT static.... God knows we're only beginning to realize how dynamic it truly is..............
@tdarnell... If you put an Earth like planet, with a similar moon around it, in a much closer "habitable zone" orbit around a Red Dwarf. Could that Earth like world last 500 billion to 1 trillion years or more since the Red Dwarf lasts over a trillion years? I'm assuming the answer is Yes?
You have such wonderful taste. The music on this and your other video's is just the best! That Cling piece along with the opening animation and your voice just brought the hair up my arms. Just beautifull Thank you for this!
Even after the darkness falls and all the stars have gone out, the smallest particles will still dance a quantum jig. Darker and darker the universe will grow, and even these particles will fail. One by one, all will decay into photons speeding their way to nowhere, the universe will grow calm. But, there will still be photons on journeys unknown. Perhaps one will disturb a waiting singularity...
..can't get it pass my head..i mean..we humans..70-90 yrs old..a red dwarf..just a couple trillion years old..it just crazy when you think about it..i mean something that can live for trillions of years..not sure if i can even count that high before my measely 80 years is up???..probably not...lol..
We need to advance and proceed, and i think one day we will be able to communicate with alien civilisations. But right now we are just not advanced enough. We are getting closer, by discovering and cataloguing more and more planets. But we have few candidates for life among the thousands we discovered, and we are not sending signals to them, also it will take much time for our signals to reach them, thousands or even millions of years. But we are not ready for that.
At the end of the video it's saying that eventually all stars will burn out and the sky will be dark. But don't new stars form all the time, so won't there be new stars after the old ones burn out?
@jaybow1982 Stars fuse their fuel into heavier elements, such as hydrogen to helium, etc. While the Sun won't go past helium, the giant stars burn all the way to iron. Fusion of iron does not produce energy, so when the universe builds up a bunch of iron, it won't be able to make new stars.
@Obelisk155 aah ok then, thanks for answering my question :)
And I was just wondering, when stars explode, then could the material from them create new stars? Or is the material that comes from supernovas all iron or heavy elements?
The material from supernovas, along with existing gas clouds, can and does form new stars. In fact, all of the material on Earth that's heavier than helium comes from supernova explosions before the birth of the Sun.
Actually, the Sun is large enough to begin helium burning at its core. This, in fact, is what will cause the Sun's expansion into a red giant. Helium will fuse into carbon and oxygen, but the core will not get hot enough to initiate carbon burning. The Sun will ultimately collapse into a carbon-oxygen white dwarf.
So what happens to a red dwarf after it's hydrogen is used up? Are they large enough to fuse helium? When they do eventually burn out; what happens to them?
Yeah, so when they burn all their hydrogen, then it will be a big ball of helium (I take it that they are too small to fuse helium) so there will ultimately big chunks of helium strewn throughout the universe??
I'm confused, the illustration at 2:45 shows that the radiative zone is on the outside of the blue giant star. Is this mislabeled, or truly reversed compared to a sunlike star?
i dont understand how they can tell what the layers of the sun (or any stars) are made of.. like a math equation can't just make it up, is it a theory or something??
In the largest sense, of course, it *is* theory, because we haven't actually sent instruments into a star. But let's be clear that "theory" doesn't mean "wild guess". We know a great deal about the behavior of gases and also about nuclear reactions, among other relevant processes. That allows us to write equations that describe the internal structure, and make predictions (such as neutrino emission rates) which have been verified by measurement.
So, quick question, do the dwarf stars have a lower gravitational field compared to the sun? How close would the earth have to be for it to get a moderate heat consistency from a dwarf star? Just curious..
So uh... you should probably work for the discovery channel or NatGeo or something along that line. You have the PERFECT voice for documentaries. Would you ever think of making a longer...almost short film style video about space? That'd be interesting to see what you'd come up with.
It's ok about not saying "keep looking up" just say it twice, next video :)... the thought is there :) also, thanks for a fantastic video...i've always been interested in the stages of a star's lifetime.
@farrell360 I think brown dwarf stars have just slightly too small of a mass to ignite. Some have suggested that gas giant planets like Jupiter are technically brown dwarfs. But I wouldn't call such planets a brown dwarf unless it had no rocky core.
Tony, your videos are some best on this site. I love seeing new ones on my sub page.
Majority of what you say in your videos I already know because, like you, I'm a astronomy geek. But I really enjoy the way you splice your images together and the tone of your voice (no homo). It lets me dream about the cosmos while I watch your videos.
According to modern science, our sun is too small to go supernova, and also too small to collapse, and red dwarfs are even smaller, that's if modern science is right.
Dear Tdarnell, could you elaborate on the possibility on life on planets around red dwarfs? it would seem a good spot, since it gets so much time to evolve. Do red dwarfs have coronal mass ejections? If not, then would that increase the amount of life-supportable planets, since they now no longer require a magnetic field?
if all the planets and stars are getting sucked into a supermassive black hole,where is the stuff going? Is it converted to some other form of energy?
Are they the best candidates for life? I would think so. They have long formidable lifespans, and they're very plentiful.
I don't want to jump the gun too soon, because I'm not a professional astronomer, but I'm betting that the majority of red dwarf stars (class M4V and up) have a habitable planet like Earth with developed life forms.
@pashedmotatos I wouldn't think they were, as they are much smaller, dimmer and cooler than the Sun, with a smaller gravitational pull and so very small chances of a planet warm and bright enough for life.
@ArmourTheLlama But the habitable zone is much further in, making the gravitational pull in a red dwarfs' habitable zone powerful and almost equivalent to the pull of the Earth and Sun. And the Sun's apparent magnitude is -26.74 in luminosity. A red dwarf's luminosity viewed in the habitable zone of a potential life-bearing planet would be around 23-25 apparent magnitude [with an average of 24]. That's only slightly dimmer in degrees than the Sun. The star would appear about 3x bigger, though.
@schizotypalgrasp Once a Red Dwarf fuses all of it's Hydrogen into Helium, the red dwarf will simply become a white dwarf, skipping the Red giant phase altogether, unlike more massive stars, such as the yellow dwarf we call the Sun. This is because a Red Giant is not massive nor dense enough to fuse its Helium.
The ending terrified me, when you said the sky will be dark. It's such a scary thought to thing of the universe ending like that. Even though all of us will be dead long before that, i wish i could live on to see the ending of the universe, although it scares me it would be the greatest experience in the world
I thought black holes take in stars and planets and expel them; thus creating newer stars and planets. So how ill everything die out if black holes will always be creating. The newly creating will just start the same system.
Is it posible for the universe becoming completly dark?New stars are being born all the time in our galaxy and not only ofcourse.Could that process simply stop?
@Alexandru017 Look up entropy :) The universe will at some point be to unorganiced, so matter will no linger form since the energy has reached its lowest state. This is know as "heat death". This is one of a few theories about the end of the universe.
@gt6303c unfortunately not, they are closer to their star than Mercury to our Sun. But that doesn't "destroy" their habitability. Within their habitable zones, life can exist if the atmosphere developed a convection of heat perhaps through water vapor to the dark side, where it is radiated off into space again.
@gt6303c Yes, the planet Gliese 581g orbits a red dwarf and falls withing a habitable zone that could support liquid water but is not tidally locked to our knowledge. Gliese 581's habitable zone lies about where Venus is in relative distance from the star. Red dwarf's habitable zones are obviously much closer than that of a main sequence star like Sol but usually not anything extreme as to make life impossible.
@tdarnell Whew, just in the nick of time -- I was worried for a minute there that I would not be seeing the meteor shower tonight!
Thanks for taking the time to make these videos for us. I know how much of a hassle it must be to edit them together sometimes, but it always brightens my day to see another one in my inbox. =)
@tdarnell : LOL... you know now there are going to be a bunch of conspiracy people thinking you are trying to tell us something, by not ending with "keep looking up"...HAHA!
@tdarnell Personally I think the way the video ended works better. It ended with all the red dwarfs dying and pretty much the end of the universe. What am I going to keep looking up at? I think it just worked better being kind of a sad note to end on, to leave that out anyways.
Great Video, I'd like to know what you think about the upcoming remake of Cosmos too!
@gamedismantler Check out Space Fan News #27, I talk about that. The punch line: I think the show will be good, but I'm nervous. Some things don't need a remake, they were perfect the first time.
perfect timing for a Tdarnell video. I was feeling pretty low checked youtbue and this beauty was waiting in my sub box like a shinning piece of gold in a sea of chaos... Thank you sir.
It's about the size of Jupiter and it's the darkest exoplanet yet discovered. It's quite an interesting find. I imagine we might well see a video about it from Mr Darnell.
The Universe is so beautiful. I have read that certain Red Dwarfs could burn for an extremely long time. Here's a wikipedia quote on the subject:
"Recent astrophysical models suggest that red dwarfs of 0.1 solar mass may stay on the main sequence for almost six trillion years, and take several hundred billion more to slowly collapse into a white dwarf."
@spiderskater3 New stars do form, but the universe's supply of hydrogen can't last forever, not to mention as the universe expands, the energy within it is spread over greater distances, so things get colder. So sadly, all stars will eventually run out of energy.
One day trillions of year from now the last red dwarf will flicker out of existence leaving a completely dark universe filled with evenly spread out atoms.

@schizotypalgrasp Once a Red Dwarf fuses all of it's Hydrogen into Helium, the red dwarf will simply become a white dwarf, skipping the Red giant phase altogether, unlike more massive stars, such as the yellow dwarf we call the Sun. This is because a Red Giant is not massive nor dense enough to fuse its Helium.

Trillions of years?! but the Universe is only into the billions :|

@sheldonlt it's analogous to that you might live 70 or 110 years, but since your birth, the universe aged just about 15 years or so..

The ending terrified me, when you said the sky will be dark. It's such a scary thought to thing of the universe ending like that. Even though all of us will be dead long before that, i wish i could live on to see the ending of the universe, although it scares me it would be the greatest experience in the world

I thought black holes take in stars and planets and expel them; thus creating newer stars and planets. So how ill everything die out if black holes will always be creating. The newly creating will just start the same system.

Is it posible for the universe becoming completly dark?New stars are being born all the time in our galaxy and not only ofcourse.Could that process simply stop?
Alexandru017 6 months ago
@Alexandru017 Look up entropy :) The universe will at some point be to unorganiced, so matter will no linger form since the energy has reached its lowest state. This is know as "heat death". This is one of a few theories about the end of the universe.

Is it possible for a planet to be in the habitable zone of a red dwarf and not be tidally locked to the star?
gt6303c 6 months ago 5
@gt6303c I don't think so, I also think the size of the planet plays a factor.
poodlelord 6 months ago 2
@gt6303c unfortunately not, they are closer to their star than Mercury to our Sun. But that doesn't "destroy" their habitability. Within their habitable zones, life can exist if the atmosphere developed a convection of heat perhaps through water vapor to the dark side, where it is radiated off into space again.
Helge129 6 months ago
@gt6303c Yes, the planet Gliese 581g orbits a red dwarf and falls withing a habitable zone that could support liquid water but is not tidally locked to our knowledge. Gliese 581's habitable zone lies about where Venus is in relative distance from the star. Red dwarf's habitable zones are obviously much closer than that of a main sequence star like Sol but usually not anything extreme as to make life impossible.

@tdarnell Personally I think the way the video ended works better. It ended with all the red dwarfs dying and pretty much the end of the universe. What am I going to keep looking up at? I think it just worked better being kind of a sad note to end on, to leave that out anyways.
Great Video, I'd like to know what you think about the upcoming remake of Cosmos too!

@gamedismantler Check out Space Fan News #27, I talk about that. The punch line: I think the show will be good, but I'm nervous. Some things don't need a remake, they were perfect the first time.

@blastardinc what do you find so interesting on some ~1kly distant star's planet and why do you call it "black jupiter"?
mykhal 6 months ago
@mykhal
It's about the size of Jupiter and it's the darkest exoplanet yet discovered. It's quite an interesting find. I imagine we might well see a video about it from Mr Darnell.

Nice explanation. Are the radiative an convective zones "switched" in medium and large stars?
fredochs 6 months ago
The Universe is so beautiful. I have read that certain Red Dwarfs could burn for an extremely long time. Here's a wikipedia quote on the subject:
"Recent astrophysical models suggest that red dwarfs of 0.1 solar mass may stay on the main sequence for almost six trillion years, and take several hundred billion more to slowly collapse into a white dwarf."

spiderskater3 6 months ago
@spiderskater3 New stars do form, but the universe's supply of hydrogen can't last forever, not to mention as the universe expands, the energy within it is spread over greater distances, so things get colder. So sadly, all stars will eventually run out of energy.
