Global warming now: I sleep
Sun exploding in billions of years: real shit
Yeah it's like, human civilization has been around for less than 0.001% of the time it will take for the sun's output to meaningfully change to such a degree that life on earth will become impossible. I think it's more productive to worry about other things first
Earth will become uninhabitable way before the sun explodes.
Last estimate I read was like 500 million years before the sun gets hot enough to start negatively effecting the water cycle, and then it just gets dryer and more inhospitable from there.
Of course, we’re artificially making things hotter way faster than that, so probably a few hundred years before large mammals have a hard time maintaining homeostasis due to the temperature.
Maybe we’ll get dinosaurs 2.0 and they’ll have enough time to get smart enough to realize we used all of the cheap energy and doomed them to die on a hot, barren rock.
Fool. Dinosaurs 2.0 just means more oil, the cycle will repeat and nothing ever changes.
Oil is mainly from plants that dyed million of years before dinosaurs even existed, before the bacteria and fungus that break down plants and wood evolved.
That’s why it’s a finite resource. You need all of that organic matter, unbroken by chemical digestion, to be heated and crushed for millions of years.
Spot on. And before plants we had mushrooms the size of trees covering the land.
The sun exploding is practically enevitable, climate change is stoppable, but it requires actual work which is bit too much effort.
The average population couldn’t make the effort of staying home and playing XBox… so yeah, humanity’s fucked

Obviously we should just move to the moon since it doesn't orbit the sun
Well about that... https://youtu.be/KBcxuM-qXec
Thank you. 30 years of misunderstanding cleared up in a few minutes. Sometimes I don't think the internet was a mistake.
Why not just make the Sun immortal lol
It's possible with our current tech.
Extraordinarily expensive, but we could theoretically do it without inventing anything groundbreaking.
tbf i feel this applies to basically all of space-everything, we can do it with current technology, it'd just be a project the likes of which has never been even remotely considered before, probably taking hundreds of generations to start making progress on.
We just need to start working when there are obvious signs of problem, not something gradual that is too subtle, the sun has to start blinking or for us to catch the message.
I'm sure if we just turn it off and then turn it back on again, it'll be fine for another couple billion years.
Kinda, but also there's stuff that we need to learn new physics for, like FLT travel.
We can create some math saying it's technically possible, but we have no idea how to create the things we need to make it work.
Then there's hibernation. We see it in some animals, but we need to know new things about biology to make it work in people.
There are many categories of "possible" and some of them mean we just need enough people working on it. And some of them mean we need to learn new fundamental science to be able to even start to understand what it takes.
but we don't need FTL travel, we could travel the universe perfectly fine with just generation ships.
Like i said, we can do basically anything it's just that it will require many many many generations single-mindedly working towards it.
Wow. Those smart mfers came up with the dumbest idea I’ve ever heard.
What's dumb about it? It sounds crazy but if it works it's not stupid right? Deeper in the article they suggest that using a lot more calcite than diamond would be far less expensive.

what
To be fair, there's a big difference between "extending the lift to trillions of years" and "extending the life forever."
No matter what we do, there's an end date to existence. Best we can do is huddle around a supermassive black hole for the last few trillion years until time itself ends.
Helium extraction lol
Finally someone asking the real questions
It won’t explode as if by supernova because it’s below the Chandrasekar limit of ~1.4 times the sun’s mass needed for that to occur.
It will, however, enter its supergiant phase, and will expand its diameter to engulf the three inner planets. Many hundreds of billions or even hundreds of trillions of years later it will collapse into its stellar dwarf phase.
E: Sun, not earth. There’s a bit of difference, I guess.
I'm pretty sure the Sun's mass is way above 1.4 times the Earth's mass, thought.
It’s supposed to be 1.4 times the mass of the sun
Yeah, you’re both correct, botched that one.

From what I can find with some quick searching, the red giant phase should only last about a billion years. The white dwarf stage should last much longer (tens or hundreds of billion years) as the sun slowly cools.
You're absolutely right that there won't be a supernova, though. The sun will shed much of its mass in the form of a planetary nebula, but it won't explode or implode.
I REALLY enjoy the use of wiki as the linked source
It has a delicious sort of passive aggressive vibe to it.
And not even something esoteric, good old entry on the entire planet of Mars!
Just move Earth to the other galaxy to orbit different star.
See Patrick gets it!
Just move Earth to the other galaxy
Can't move it to another galaxy because their stars will be going out, too.
Just move it to another universe.
This X account is from a Space Karen simp
It could even be a Space Karen alt, sounds cringe enough
I'm pretty sure its his alt, not that i have much proof.
Im surpriced muskas didn't deleted that function until now.
Considering they were his idea (or he claims they are) I doubt he will.
Likely he deletes some community notes...
While true, as the sun expands in old age the habitable zone will move outwards in our solar system.
We only realistically have about a billion years left on this rock. Twice as far in the future as the Cambrian explosion is in the past (500 mya).
They haven't thought it through enough.
Considering their username I’m guessing it’s some random grift to either give Elon money or scam people out of money by convincing them Elon will give them money it they just transfer a lil sip into some crypto wallet somewhere
