We will have the collision with Andromeda Galaxy a few billion years before, so don’t worry :)
Colliding with andromeda won’t do anything. Galaxies are almost all empty space.
We’ll see.
No. We will not.
You won’t mortal
What if some alien civilization is watching the whole thing and taking bets
But it will be beautiful to watch!!
5 is a few
Nah, we will build a stellar engine prior and move ourselves wherever we want. We will have colonized all the Milky Way and most of Andromeda. It’ll be like a brother and sister finally meeting near the washer.
The sun is also slowly increasing in energy output. Earth will be too hot for complex life to exist in about 800 million years.
Space is so vast that the Earth and Solar System will survive.
Although the galaxies will plow into each other, stars inside each galaxy are so far apart that they will not collide with other stars during the encounter. However, the stars will be thrown into different orbits around the new galactic center. Simulations show that our solar system will probably be tossed much farther from the galactic core than it is today. Source
Tbh I think this shared experience kinda shows to me how we grow selfish as we grow up, we were quite aware that it will not affect us, but the thought of the world where we see so many people living ending one day like this haunted us, now we don’t care, we don’t care about anything that doesn’t affect us or people we know…
Personally I’ve always been into space exploration stories (I mean, Star Wars isn’t always exploration (I read the books, and some are about uncharted stuff a bit, like Outbound flight, and I do like Star Trek too) and kinda hope we’re at that tech by then. I also really enjoy stuff like Schlock Mercenary and videos like https://youtu.be/ulCdoCfw-bY which while showing a bomb, also talks about a way to use black holes to outlive Red and White Dwarves, which normally should be the last source of light and heat in the universe. A colony properly using the energy black holes would still contain could potentially last trillion of years longer than all stars.
What’s scary is that was already a few years ago, so it’s a EVEN CLOSER now!
There is a certain sort of ennui that comes with the realization that the heat death of the universe is inevitable, and no matter what you do, no matter how much you manage to make your mark on the world/solar system/galaxy/universe or how successful and prosperous your descendants may be, it will all eventually be lost to eternal entropic stasis.
Come join the last vibration
Whoa what do you call this crazy noodle haha you guys know how to party
Have no fear, the sun will not explode. You need about 8 times the mass of the sun in order for a star to explode in a supernova. The sun will expand into a red giant when it finishes fusing hydrogen into helium. When this happens the earth might be swallowed up in the expansion. After the sun finishes burning helium and continues up the fusion chain to iron the fusion in the core will fail and the outer layers of the sun will puff off into a planetary nebula. This won’t be a particularly violent event. The naked core leftover will be a white dwarf which is effectively just a molten ball of mostly carbon and oxygen gradually cooling off. It will take trillions of years to cool off.
too late. i hear the sun has already started exploding and that it’s allowing humanity to exist.
Humanity will either be long dead or colonizing other planets by then.
I read somewhere that the sun might expand a bit and become too hot for Earth in just 500 million years time, so it might be a shorter window than you’d think
You’re missing a zero. The sun will expand into the red giant phase in about 5 billion years.
The sun will get brighter in 500 to 600 million years to the extent that many plants won’t be able to survive due to disruption to the carbon cycle. Expansion comes later.
This is what I’ve heard, that basically if we were stomped back to single celled life today, evolution would not have time to bring back visible plants and animals before the earth became uninhabitable. So there’s no starting over. I admit it kind of depresses me.
DON’T PANIC!
let’s feed it more hydrogen!
Star lifting. Mine the metals and shit out of that star and it’ll potentially live trillions of years.
And no need to worry about political will. Thar’s gold in that thar sun!
Gold only forms in a supernova
Gold isn’t formed in the sun but plenty exists there for the same reason it exists on earth. Ancient supernova that provided the material for our star system.
But gold is just one thing they would mine there of course. My comment was referring to the value of the materials mined, not just the literal gold.
Is this a universal experience.
10 year old me: get me some science books what can we do to speed it up
Throw iron into it.
A lot of iron.
Atlantis is under water because water is immune to fire. Checkmate.
