RU-vid Servers won’t last that long. But if it is backed up constantly on Hard Drives it could be real if the Solar System won’t be affected by the colision with the Andromeda Galaxy. Or as the other dude said,if the sun is facing us while doing a reaction like in 2012,we wouldn’t have anything working for like 10 years because of the Radiation it would emmit,we would do fine though.
Half of scientists doubt humanity will make it out of the 21st century, let alone 4.5 billion more years. In all probability, interstellar travel is also a pipe dream due to the insane amount of energy and time required to travel such distances. Humanity will in all likelihood just be a very interesting footnote species, joining the 99% of all life that has already gone extinct. The simple fact is that catastrophes happen enough by themselves to be a serious challenge for any species to last billions of years, and humans have a special knack for creating our own; as we've already seen with global warming, ocean acidification and deforestation, habitat loss, and diminishing potable water supply. It really will be a miracle if humanity survives long enough to contemplate a new home.
Avery Games. I am kind of a Christian, but I subscribed to aton. Now I know what your thinking, "How are you Christian if you subscribed to aton?" Yes you are correct, but I go to a Christian School.. and how the Bible says the earth is 6,000 years old,, I just.. kind of don't think that. All of the rocks I've seen and fossils, I think they are millions of years old. And the earth is not 6,000 years old to me.. it just doesn't seem right.. but yes, I believe what the Bible says, but that one thing it says I just think that it is false..
Anna Dunham I suggest you to challenge what you believe, put it to the test of science. If something is real its got to be provable. Keep your mind open and thinking outside the box, you will be very surprised with the results.
Fascinating video Anton. I think another way of looking at this would be as our Sun increases in size, calculating when Mars will be in the habitable zone, then Jupiter, Saturn etc.
we are also pretty certain that the sun will lose mass as well when it becomes a red giant.. less mass means everything orbiting it will move outward from it. u didnt account for this, u left its mass at 1. even a few % loss can make a huge difference in many of those closer moons & their temp. another thing u simulated adding 1 earth atm to to them, with the moons being smaller than earth 1 earth atm here =/= the same on a smaller body, like for pluto, 1 atm on pluto would be a massive amount & probably too much
I don't know about the planetary orbits. The sun will lose mass (in enormous pulses that will themselves be extinction level events for us if we're anywhere near it), but that doesn't necessarily mean the planets will move farther away. The current planetary orbits are the result of an incredibly complex system of interactions over billions of years, so it's really hard to say (imo) what would happen at that point. Some planets might move farther away, while others spiral into the sun. Good point about the atmospheres! Adding less than 1 Atm could make some of the outer moons habitable, since there'd be less of a greenhouse effect. But none of these objects would be as good as the Earth, since they're so small and exposed to cosmic radiation. We'd have to do some serious renovations on them.
Until now I never knew how long red giants stay in that state for, now I know. A billion years or so. Thank you for that and great video. Liked and subscribed! :)
@Omer Bekcioglu all the closer planets will be consumed by the sun when it becomes a red giant. So living in Mercury when the sun's a white dwarf is out of the question.
Anton, will the mass of the sun in 5 billion years still be "1 sun" (as of today)? I guessed it may be much lower. How much mass will it have lost after that time? Great videos, keep up the good work :-)
Serious question here: The sun expands to that diameter because it has exhausted its fuel and lost much of its density. This means that it can no longer maintain the sustained nuclear process by which it generates the heat it currently does. Wouldn't this mean that the "temperate zone" wouldn't expand like is being assumed here?
Is there any science fiction series which takes place 5 billion years in the future in the Sol system? That would be a cool series! Imagine, a protagonist living on a terraformed sedna, walking outside during the periapsis point, but having to go into a vault while climbing up to apoapsis and back down due to getting too far from sol. On Orcus, people live on a water world.
I wonder how long a full orbit of the sun would take on one of those 'habitable' planets in the outer solar system? A very long, long time, I'd imagine.
Another excellent video - spot on for my hobbyist level - not too dumbed down, not too esoteric - right in the habitable zone! (What's an "albedo"? Should I care?)

We can of course convert any matter, like the Earth or asteroids, into sun-orbiting habitats, and position ourselves wherever we like, even fairly close in.
"Europa must be just buggy or something" -maybe the game is simulating the enthalpy of vaporization of water here, same principle as water cooling AC units. Basically, energy is needed to evaporate the water and thus the surroundings cool down. Im not a 100% on this one though.
This blows my mind. Those outer solar system bodies are mind blowingly far away. To consider this is how far one must go for habitable temperatures really illustrates how large the sun will become
Wasn't there also an argument that the reason the star grows larger was because it's mass was reducing, gravity was weakening and thus the surface would balloon out. On the same topic of lost mass, lower effective gravity would also cause the planets orbits to expand outwards due to a weakened influence. As the star grows so does the orbits expand.
The thermal habitable zone here seems to obey inverse square law. Which is 50AU for 2500 sunpower star. Perhaps stars like R136a1 are emmitting deadly gamma rays that move the habitable zone out where it's cold but at least you won't get radiation sickness.
Actually, the sun will be losing mass during the red giant phase, causing the planets to move further away from it. So, given that the planets move far enough away, the moons of Saturn, Uranus, and Neptune might reach habitable temperatures for some time.
Nice info! Curious here, wouldn't our Sun loose mass, resulting in lower gravity and evntually pushing earths orbit further? Maybe, earth still remains in the habitable zone?
Here would be a fun simulation. What if a Type 1a supernova occurred in our solar system where the Sun is? Obviously the Sun will never, ever go supernova, but it would be interesting to see what would happen to the planets if it did. Like, which ones would be vaporized and which ones survive and stuff.
Stars such as gliese 710 come close to the Sun, I expect plans to be in place to migrate whole planets within the next billion years (if we make it through the great filter)
when the sun becomes a red giant would it also be putting out less energy as it is now? i think red giants are actually very cool. so the habitable zone may not shift all that much.
This only matters if you assume we'll be living "dirtside," on actual planets, 5 billion years from now, rather than in artificial orbiting habitats. Also, colonizing many Kuiper Belt objects like Sedna in an Earthlike fashion would be pointless because their elliptical orbits will only make them intermittently habitable.
Add just enough air to Triton to make it a good temperature. If the sun is bright as a red giant, that's only 2,700 solar luminosities. Imagine if you put R136a1 in there that shines with the force of 8.7 million suns.
Let's also not forget that the only reason Titan has an atmosphere and liquid lakes on its surface is its extremely low temperature. If Titan's temperature was, let's say, 25°C, its atmosphere and methane lakes would fly away into space, leaving a plain space rock behind.
I downloaded a pirate copy of this game last night to see what it was like. Its got heavy piracy protection and constantly asks you to buy the game, but after seeing the potential from just a couple of hours fiddling, I'm not only buying it when I get paid, I'm recommending it to my family and friends. See? Piracy boosts sales.
The remedy is to mine the Sun, making it less massive just fast enough to counteract what would normally be its natural increase in luminosity and size.
Europa is not bugged it is melting and evaporating or sublimating like a comet and thus is losing heat rapidly. once all the water is gone then it will heat up.
It’s interesting to think about, but has a serious flaw. We would of had to move out/away from earth before it turns into an oven. So it’s either we jump moon to moon in the habitable zone, or we travel to the final moon destination and endure the extreme cold. I find the moon to moon option to be the best bet, but who knows by this time we would of probably been extinct.
Great video, I love it! I guess we're gonna have to move to Mars, then Europa, then Titan, then eventually get to the planet with the biggest heart - Pluto and then even further to Eris, the goddess of discord, haha!
The best suggestion for humanity’s new home will definitely be in perhaps an earth like planet,such as a planet that is at least 4 or maybe even 5 light years away,and the best candidate I see is one which does either orbit Proxima Centauri or Alpha Centauri. We will need to have the advanced technology which will allow humanity to reach these distant worlds,much less colonizing them. Humanity needs to start making such preparations far in advance of what happens to the sun. Humanity in that time,providing that the solar system still exists will make all necessary preparations to travel to its future habitable earth like planet. I am positive that technology will be so far advanced which will allow us to survive on such habitable planets.
Wow! That will be very hot in 5 billion years from now but a wither, wither skeleton zombie pig men , a magma cube and a ghast will spawn in 4.5 billion years
All hypothetical because if we left earth when it started to get hot, these outer objects would still be far too cool. Would need to planet hop gradually.
Will de orbit not change when Sun will became less dense, not even mentioning the loss of mas? Also, Earth will tidally locked by then, so one could hide on the dark side?
Guys Here is the problem with this. This star we have isn't a red giant it's still as hot and emits as much light as the sun we have 5 billion years ago. So therefore this is unrealistic
Since we have a lot of time before that, could we build a planet, by crashing astroids & dwarf planets together to make Earth 2.0? I realize that this would be a difficult issue, but if we forced the collisions, would a planet that we could terraform be the result?
I like your video! Actually, The Sun will swells in size, it will became a red giant. It have some stages like: Main Sequence, Late Main Sequence, Subgiant, 1st Red Giant Phase, Red Clump it will shrinks in size, and the final stage is Asymptotic Giant Branch (AGB Star) It will became a Red Giant in 7.5 Billion years. And it will loose mass quickly. And it will reach 256× times its current size. It will reach Earth's Orbit of 1.85 AU because the Sun loose mass quickly. And after that it will became a White Dwarf. It will cools down for many billions of billions of years. And it will beacome a Black Dwarf.
There is this material that has high ability’s for long term space travel but it’s hard to collect if we keep collecting it we could possibly get to another solar system that has a planet habitable such as earth I believe that I’m pretty sure that scientists have found places similar to earth if humans may get smart enough and have the resources we might be able to escape certain extinction
Chooses arbitrary sun scale and arbitrary time in the future to demonstrate that the entuire solar system is completely uninhabitable. Wouldn't it have been more interesting to ask "When would planet xxx become habitable?
Saturn actually has 2 moons that we'll be habitable when the sun becomes a red giant, I forgot which moons but there is 2 moons habitable when the sun becomes a red giant, and one more, Pluto we'll also be habitable for some time, it won't be habitable till the sun becomes a dwarf, it well be habitable for a bit of time
