  • gotta wonder what planets have existsed before us and thrived only to die, its interesting

  • I DON'T WANNA DIE!!

  • This is only a prediction.....It does not mean this will happen. The sun will likely NOT turn into red giant. However, Venus may be inhabitable even though it is the hottest planet right now.

  • what do u mean its only a prediction?!?! a prediction after seeing the result of trilloins of other suns die out and create nebulas and white dwards!!!

  • - NOT!

  • I heard the tidal effect the Earth has on the Sun will ultimately destroy it. do you think this is the most likely outcome

  • There has been some research that hints that even if the Sun doesn't become big enough to consume the Earth, Earth's gravity will still cause plasma to bubble up and engulf it anyway. No matter what the specific outcome, though, it's bad news for habitability. Luckily it's still a long time off.

  • what if the sun just came from red giant going to white dwarf.

  • lolz k eventualy the matter left from the planetary nebula from our dead sun will yes will indeed help make new stars as it gets blown off and eventualy collapses into more new birthclouds to form new suns and possibly new planets like another earth and perhaps more new life and also since mars and the other giant planets will be far away they will survive however planets like jupiter will just collapse and be stripped to their core like saturn will be.

  • We better evolve to some sort of super humans.

  • Or better yet just stop fighting each other and start working to colonize other planets and star systems.

  • Will our sun help make new stars?

  • Perhaps. Some of the material shed by the Sun will end up mixing back up into deep space and could one day begin coalescing into new stars. Typically, though, we think of supernovas from much more massive stars than the Sun as the ones that help trigger new star formation.

  • It's so tragic when you think about it.

  • thats scary when that in about 5 billion years the humman race may become extict.

  • maybe .. but 5 billion years is a long time ..

    we could become advanced enough to move to another planet by then .. even if we do hit the 5 billion mark .. theres many other catastrophies that could end us aswell

  • Wait, can't we terraform Mars before the Sun turns into Red Giant?

  • There have been a lot of proposals written up about terraforming Mars. There are a lot of technological challenges, plus the fact that when you make Mars warm enough for humans to live comfortably on, oxygen in the atmosphere starts hitting escape velocity and leaking off into space, making it a poor long-term choice for terraforming.

  • I feel that floating cities on Venus is preferable.

  • Mars may Terraform by itself during the Red Giant phase

  • will this eva happen 2 the other planets r will somthing simular hapeeen?

  • i cant wait for this to happen

  • in a thousand years man never gets smarter, he learns more from others experience

  • well now that i know the sun wont die or burn the earth i can continue worrying about meteors hiting us ^_^ thanks now i have 1 fear less i just pity the ppl that actually see this in the future

  • well be in a happyer place b4 that happens

  • Here's another question. How can they have a picture of the milky way galaxy. I mean we are init you can't take a picture of the outside of a box if your inside it. DO they take pictures of similar galxies? Or do they take pictures of what they see and use digital imaging to mkae the picture? Or is there something the government is hiding?

  • Some sources use images of other galaxies, but the Spitzer image you see of the Milky Way from outside is an artist concept, based on the maps we've done. The basic technique used is to measure the number of stars at any given distance in all directions. Sort of like standing in a single city block and seeing how many buildings you can see in each direction, and counting how many blocks away each one is. You can get a good idea of the city grid even though you can't see everything.

  • no.. the milky way is a spiral galaxy

    they take a picture of PART of the milky way (obviously we cant take a picture of our own galaxy)

  • heres a question if all galxies have ablack hole at the center then why do pictures of galaxies have a bright center. S3cond is that because it is sucking up light and what happens to the items sucked up

  • The centers of galaxies have millions of stars clustered in them, so the light from them shines very brightly between the central black hole and the observer. As for what happens to things that enter a black hole, that's still the subject of a lot of ongoing research. That could be your doctoral thesis! :)

  • Are you an astonomer or something?

  • I'm not an astronomer by training (I actually majored in liberal arts, though I was a geology minor), but instead I specialize in understanding the results the working astronomers get and finding ways to explain them in plain English. Folks who work here actually come from all sorts of different backgrounds!

  • don't worry human race was already vanish at that  time,

  • thank u this was a very extremely useful information lol.i ll take this in consideration in 5 billion years.

  • Good thing we won't live to see the day it all happens.

  • You're all naive, we will have died out by then evolution wise! Lol!

  • 1:56 lol

  • if the sun dies we all do cause most plants will die wich is food for a lot of animals that we eat and that will decease causeing a high demand for meat and greens which we will not get a lot of and the population will decrease dramaticly till we are all extinct

  • We also have 30,000,000,000 years before Andromeda collides w/ the Milky Way. The 2 galaxies will become massive black holes, swallowing each other in a giant maelstrom.

    Good luck!

  • actually, the Andromeda and the Milky way will collide to make another galaxy. The supermassive black holes from both of them will transform in one and keep the galaxy from falling apart

  • The Human Torch We Live Through ALL OF THIS THAT BASTARD XD

  • COCKROACHES WILL SURVIVE!!!

  • haha lmfao sounds lyk ur more worried about crockcroches den urself lol

  • is that our futrue?

  • noooooooo y is this the future in a billion years?

  • Because stars don't last ever,including the Sun.

  • No need to worry, guys. We have 10,000,000,000 or so years left before it hits the fan.

  • the sun never die peeps

  • hey hey everybody clam down it might cool to see the planets

    we might live in Jupiter. wait what about our beautiful air

    i don't want to move

    i hope that will never happen

  • i feel lyk a nerd o_O lol only jokin

  • Scientists estimated that all the living creatures would have died out before the Sun dies out.

  • You know who's going to survive all of this mess don't you?? The frickin' cock roaches. HAhaha. They manage to survive everything. J/k of course.

  • and mercury will be the first planet to experience this

  • uh! that black hole seems very scary!

  • its okay the sun might last forver

  • it better be 5 billion yrs later

  • listen that will never happen

  • actualy guys to elaberate it one last time lol true our sun will indeed cause our oceans to evaporate and boil our atmosphear away but there is another twist lol like the fact that the sun is not big enough to go supernova the dying future sun we will only see as spirits also wont be powerful enough to keep the eternal foundation of our system together so in other words the less mass/power there is in its super hot core the less gravity there is to hold it all together.

  • yeah true only stars 8 times bigger than the sun will die as a supernova

  • yay! that was interesting

  • wad about global warming??

  • They should make a movie about this. But have it happening in modern time.. like, some tragic event causes the sun to explode and turn into a white dwarf in only a year's time, and the people of earth have to find a way to do something about it.

    it'd be like the day after tomorrow.  yeah that'd be an epic movie.

  • good idea , but first sun will transform to red giant ;]

  • Wait... If sun turns into a WD, Wouldn`t the magnetic field decrease, making all of rhe planets go away, flying ( SWOOOOOOOOOOOOOOOOOOOOSH!)

  • Magnetic fields don't have much effect on orbits, and since the white dwarf will be about the same mass as the Sun currently is, the gravity won't change much, either.

  • actuaualy as the sun looses more energy it will since its gravity to hold the solar system depends o the amount of mass lol the less mass and power there is in the dying sun the less gravity there is to hold the eternal foundation of our solar system together.

  • Lol it will actually get hot enough to evaporate our oceans and atmosphere in 1 billion years. Well actually in half a billion years as the carbon dioxide will have long escaped the atmosphere after we run out of fossil fuels (well that's only in the next few hundred years) and the

    atmosphere then empties of it's C02. We'll lose all vegitation and then we will die.

  • The CO2 doesn't just disappear from the atmosphere like that. Look up "the carbon cycle".

  • That's true, but if we were able to get rid of most of the Nitrogen starting in a billion years or so (which is all the time that life has left on Earth), we would be able to live under the intense heat of the sun for about 4 billion more years after that.

  • Your saying people in 2109 will die?

  • omg

    amazing and incredible

    mightbe we could just shift home to pluto

    wait, i heard that NASA revealed that there will be an asteriod hit in 2019

    very less time

    ENJOY LIFE

  • By then we might even find a way to teleport our entire planet via worm hole :)

  • Lol i think we just get our sunbeds out and enjoy the sun til we eventually die :D

  • who cares stars change size all the time

  • Wow. That's scary. My great great great great great great...etc...grandchildren are gonna suffer.

  • Ok i'm offishly scared out of myself.

  • You'll die eventually anyway, this way would just be a much more awesome way to go.

  • well to speed up earth we don't have the tech right now but only time will tell.

  • how do i get to narnia?

  • Why couldn't we use the many comets and asteroids to gently nudge earth's orbit outwards? Suppose we could land a device on each large one that was clever enough to very gently alter the objects orbit so that it intersected the earths orbit in such a way that it tended to speed up the earth moon system?

  • Then we would have no sun and we'd be frozen and light-less anyway... Why don't you let the people from a few million years into the future work out the solution?

  • actually we gotabout 3 bilion years because the andromedagalaxy will collide into milky way and create a super elliptical galaxy making ours the biggst galaxy in local group :D well it might send us off orbit

  • i think the people in earth will be smart by then. we will move to another solor system will keeping warm :P

  • are u sure?

  • TOTALLY

  • But considering that our galaxy is 100,000 light years across, I doubt that just one generation could make it out of our solar system to find another. There would have to be some kind of craft and people, as weird as it seems, would have to reproduce along the way. This would take a very looong time.

  • what a bummer

  • 5 billion years we don't have long

  • swallows the earth whole? OM NOM NOM!! :D

  • Lol, the sun will engulf Earth, thus consuming it.

  • thank you Dr., I really enjoy your videos. Now excuse my ignorance if this is not related to astronomy, but do you think you could make a video explaining the relativity of time ?

  • Unfortunately, college-level courses have a hard time explaining relativity correctly, so it's not likely we can get something understandable into the format of these videos, but I've asked Dr. Brinkworth to see if she can come up with anything. But there are a couple of good text-based explanations online if you search for it with something like "plain English" in the search field. :)

  • i know! we can make a some big big huge devise that will get attach to the earth and will balast off like rocket expect the earth will be the rocket and we will move away from the sun at the sun will far away as normal and earth won't have to die!=]

  • it'll still freeze cuz no heat????????

  • Thats smart!! Your a smart one, arent you. But unfortunately it will be impossible to make a huge devise and "attach" it to the Earth! lol

  • thats what people said about flying before planes were invented

  • a white dwarf is basically a giant diamond!

  • we are gonna be dead in 3 billion years

  • human being live about 120 years thats a centry

  • you have a present time life time you will die before hey dont be afraid its our fates to die so what its just a death you wont feel a thing no after life is good you cant think this is boring because you dont have a brainYAY

  • if the sun dies we won't be in earth

  • 5 billion years well try to find a planet lol

  • haha get him the planetary jacket

  • So we basically have 5 billion years huh?

    Gnarly.

  • wrong we have a little more than 3 billion because of the andromeda galaxy

  • Damn.

    Why God? Why?!

  • Because there is no god

  • Why should we care about anything beyond earth's orbit? Knowing about other stars doesn't solve world hunger.

  • Dude stfu nobody cares about world hunger. Knowing stuff is all that matters. =D

  • 'cos 90% of the stuff you take nowadays for granted (tech specially) that helps in many mnay ays are a biproduct of space investigation (telescopes, astronauts, ships etc brought to dayly use) so as you can see we can do more than your simplisctic view of the whole thing Mr. genius... ¬¬

  • We`ve got to get out of town by sundown!

  • We should build a circular dome thing around the earth that gives off heat and light and then attach rockets to the earth and push it to a new star! Sounds pretty complicated and expensive but in 5 billion years I think we will be smart enough to pull it off.

  • You mean like an artificial environment? Probably possible. And if the world was gonna end soon, I think everyone would temporarily make everything free so we don't die. But that's around 3-5billion years, so we might have evolved or died off. The rockets would most likely be too hot and just kill us, so that is not likely. Best way is to just move.

  • We should move to Neptune :)

  • Yes. Neptune roxers boxers.

  • dude neptune is made out of gas how could we step on it we'll get crushed before we even get to breathe!

  • IMPOSSIBLE.

  • human race will not survive as a single planet species.

  • yeah and even if they do - they wont have long to escape -- especially the actors and actresses who stand and watch disasters happen not run XD - omg a car is comin toward me!! lets se how this unfolds XD

  • how fast will the sun's size increase when it dies?

  • aout 8 times

  • hope im a cyborg by then.

  • perhaps as the sun gets hotter, the habitable zoge gets bigger, and mars will be the "new earth", then titan, ganemade or europa, mabye even pluto, but i doubt it. wonder if by then, if we are still alive, have the tech to harvest dead stars of their resources.

  • heheh the sun will become the new face of the Earthen daytime sky and belive me being around and looking up at a sky full of bright burning plasma is gonna be HUGE.

  • ohh crap is a girl sorry.......it didn't see her chest

  • did guy is so young and his a doctor,,,,crazyyyy

  • 1. I actually believe that it's possible that Earth will not just stand still ,the sun may expand out its orbit.

    2. There is a very small chance humans or anything else will be alive to see this. Humans will ether kill themselves off through war or some other ignorance. Or die from the suns gradual warming prior to the red giant phase.

  • Not to mention the likelihood of meteors, ice ages, or disease killing us off before the sun reaches the red giant phase.

  • the earth's habitat would be long long gone before this sun's process initiates...the Earth would completely cool down in about 500-600 million years and literally making all the oceans dry...Even some how Sun stays there in the same its in right now forever it cant be changed :/ EVERYTHING IN UNIVERSE FINALLY DIES

  • Honestly, that jupiter and pluto idea dosent seem so bad. In fact if we lived all the way out there, without an atmosphere none of us would be here. BUT, if pluto did have a atmosphere, our bodies would be evolved to withstand that kind of cold. ALthough, we arent there, so SUCKS FOR US.

    Kidding. I bet humans will not last the 5 bil years it will take before all this. So, again, no need to worry!

  • meh actualy thats more better for us unless u wanna become a mini version of satan and be burned to a crips or possibly be devoured by the face of that huge deamon beast

  • hahahaha

  • MORE BETTER?

  • *laughs*

  • why couldnt we be where jupiter was :(

  • its obvious if we were in jupiter's spot then we wouldent be able to live on Earth lol.

  • BURN BABY BURN!

  • Y COULDNT WE BE WHERE PLUTO WAS >:(

  • is there u point wen all life on Earth will be destroyed besides that?

  • What's the time lapse between Reg Giant and White Dwarf? Would it be long enough that something like one of the moons of Jupiter or whatever would be able to develop life due to the new heat source?

  • The last set of numbers I saw implied that the Sun would be a red giant for several million years. That's enough time for some primitive life to evolve on one of the moons of Jupiter (which will most likely be in the habitable zone then), but probably not long enough for complex, intelligent life to rise up.

  • Guys, don't worry about this. 5 billion years?? We would be dead by then! You don't have to worry about that cause surviving after 5 billion years is impossible! Just enjoy life because after 5 billion years we would already be dead.

  • it will die but like whoo we will die of old age or sickness but the sun will die like in 5,000,000,000 years mabe aliens on earth nah jk

  • You people dont think in god he made the sun in a way so it will not die so i think you are wrong how can you tell us how the moon got bigger in 5/4/2006 well a comet gravity push the moon to the Earth well can you solve it Spizerjim?

  • hate to break it to you, but the sun was made by condensing nebula, not god, and it will definitely not last forever.

  • Hahaha I would trust world renowned astronomers before I would trust some religious text.

  • that's exactly what i was thinking!! so im not worried.

  • The whole point of space exploration is that one day we'll have to move to another planet & we are in the beginning stages of looking for near habitable planets.Once the sun dies we can't be here so we have about 5 billion years to do so but with the andromeda collision coming even sooner doesn't this mean we now have to find a new galaxy to live in.I thought moving to a new planet was plausible but a new galaxy is probably impossible if you know the distances between them.Are we doomed?

  • There is a video which maintains that the collision of the two galaxies will be catastrophic. But why exactly should it be? The space betwenn the stars is so large that probably no star of the andromeda galaxy will actually hit one of the milky way. so what?

  • i thought it would turn into a black hole, then how are black holes formed

  • Nope. Not enough mass in the Sun to form a black hole. Black holes only form from extremely large stars.

  • Why can't the merged atoms merge again and what is the next chain of nuclear fusion.

  • I'm no expert but this is how I understand it. Once the material that constitutes the mass of the sun has been turned into carbon the heat still generated by the sun is not sufficient to fuse the heavier atoms (this actually does happen in super nova which is where all heavier atoms come from according to Fred Hoyle's calculations) so in effect not enough gravity + heavy atoms = no heat = no fusion = a cooling, shrinking, white dwarf. Fairly sure that's right

  • There's a lot going on. The bigger the atom, the more energy required to fuse it. So, as anothergazman says, a star the size of our Sun is simply too small to fuse anything bigger. But even with huge stars, once they start fusing anything heavier than iron, the nuclear forces are so strong that they blow the star apart. One of our scientists likes to carry around an iron skillet, holding it up and saying "This killed a star!" :)

  • thats cuz iron for most larger stars is an unfuseable elemant lolz any large star bigger than our sun that tries to fuse this element will fail compleatly therefore causing it to self destruct in on itself lolz for this to happen to our sun lolz not only will it need more mass but will need a ignition temprature of 6million degrees for the carbon and oxygen fusion to ignite.

  • cuz our sun is not actualy large enough lolz

  • Thank you sun hang you can do it try to produce helium but I wander if humans will devolope powers then.

  • Yeah, I have a question. What happends when a brown dwarf star goes into the oort cloud? =\

  • There was a hypothesis floating around in the '80s that proposed that a brown dwarf or undiscovered planet might occasionally pass through the Oort Cloud, knocking a lot of comets into the inner solar system and increasing the bombardment rate of Earth, and that would cause mass extinctions. However, no observational evidence could support the theory, and we now think there aren't any brown dwarfs close enough to interact with our solar system.

  • lol 2:06 Mars turns into an earthlike planet

  • That's actually Titan...

  • lolz actualy thats Mars followed THEN by Titan.

  • 5 billion years, lets get ready already.

  • did you get this from me or another user?

  • sorry this is my old user, im glok6, not 13GVU

  • We actually pretty much the same question from three different people over the course of a week. We figured that was our cue to answer it. :)

  • REALY INLIGHTNINTG

    THANK YOU

    AMAZING!!!

    but we know that the sun is loosing "volume"

    then the magnetic fields will be weaker and then what

    the planets will crush to each other ???

    and then what will happen to the earth???

    :(

  • Changes in the Sun's magnetic field shouldn't affect the orbits of the planets. It could change the amount of radiation hitting the planets, but it shouldn't cause any collisions.

  • This was a great video. Thank you

  • By the time the sun dies we will most likely have the technology to colonize another planet. Or perhaps just live in space stations.

  • and where the hell are we gonna go..and how are we even going to leave?

    lolol

  • lool 5 billion years..

    in 5 billion years we have no more water and with the cuntinuing of global warming...

  • isnt there a 3rd possibility that the suns gravity becomes weaker and earth escapes the gravity of the sun?
