I REALLY enjoy the use of wiki as the linked source

[-] OwenEverbinde@lemmy.myserv.one 8 points 7 hours ago

It has a delicious sort of passive aggressive vibe to it.

[-] i_dont_want_to@lemmy.blahaj.zone 161 points 15 hours ago

Global warming now: I sleep

Sun exploding in billions of years: real shit

[-] SkyeStarfall@lemmy.blahaj.zone 41 points 15 hours ago

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

[-] Zron@lemmy.world 26 points 14 hours ago

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.

[-] SaharaMaleikuhm@feddit.org 11 points 12 hours ago

Fool. Dinosaurs 2.0 just means more oil, the cycle will repeat and nothing ever changes.

[-] Zron@lemmy.world 10 points 11 hours ago

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.

[-] MutilationWave@lemmy.world 2 points 8 hours ago

Spot on. And before plants we had mushrooms the size of trees covering the land.

[-] LaserTurboShark69@sh.itjust.works 108 points 16 hours ago

Obviously we should just move to the moon since it doesn't orbit the sun

Thank you. 30 years of misunderstanding cleared up in a few minutes. Sometimes I don't think the internet was a mistake.

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.

[-] slingstone@lemmy.world 2 points 7 hours ago

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.

[-] Danitos@reddthat.com 15 points 14 hours ago* (last edited 14 hours ago)

I'm pretty sure the Sun's mass is way above 1.4 times the Earth's mass, thought.

[-] ILikeBoobies@lemmy.ca 16 points 14 hours ago

It’s supposed to be 1.4 times the mass of the sun

[-] don@lemm.ee 5 points 13 hours ago

Yeah, you’re both correct, botched that one.

[-] FooBarrington@lemmy.world 1 points 13 hours ago

But if it had 1.4 times the mass of the sun, we'd have way bigger problems than a measly supernova

[-] chemicalwonka@discuss.tchncs.de 23 points 14 hours ago

This X account is from a Space Karen simp

[-] Thorry84@feddit.nl 16 points 13 hours ago

It could even be a Space Karen alt, sounds cringe enough

[-] HEXN3T@lemmy.blahaj.zone 47 points 17 hours ago

Why not just make the Sun immortal lol

[-] mipadaitu@lemmy.world 28 points 16 hours ago

It's possible with our current tech.

https://youtu.be/pzuHxL5FD5U

Extraordinarily expensive, but we could theoretically do it without inventing anything groundbreaking.

[-] Swedneck@discuss.tchncs.de 33 points 16 hours ago* (last edited 16 hours ago)

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.

[-] HawlSera@lemm.ee 1 points 8 hours ago

I mean it's worth it to be able to rewrite the laws of physics on the fly, we could even make the human soul real and rez everybody!

[-] mipadaitu@lemmy.world 9 points 15 hours ago

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.

[-] Swedneck@discuss.tchncs.de 2 points 2 hours ago

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.

[-] kubica@fedia.io 11 points 16 hours ago

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.

[-] flicker@lemmy.dbzer0.com 2 points 12 hours ago

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.

[-] user224@lemmy.sdf.org 3 points 14 hours ago
[-] tacosanonymous@lemm.ee 2 points 14 hours ago

Wow. Those smart mfers came up with the dumbest idea I’ve ever heard.

[-] MutilationWave@lemmy.world 3 points 8 hours ago

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.

[-] HEXN3T@lemmy.blahaj.zone 6 points 16 hours ago
[-] mipadaitu@lemmy.world 10 points 15 hours ago

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

[-] drew_belloc@programming.dev 5 points 17 hours ago

Finally someone asking the real questions

[-] introvertcatto@lemmy.blahaj.zone 23 points 16 hours ago

Just move Earth to the other galaxy to orbit different star.

[-] apj2k36@lemmy.ml 12 points 15 hours ago
[-] introvertcatto@lemmy.blahaj.zone 6 points 15 hours ago

First time I heard of this movie. Might watch sometimes.

[-] UnderpantsWeevil@lemmy.world 4 points 15 hours ago

Just move Earth to the other galaxy

Can't move it to another galaxy because their stars will be going out, too.

[-] introvertcatto@lemmy.blahaj.zone 6 points 13 hours ago

Just move it to another universe.

[-] VubDapple@lemmy.world 5 points 17 hours ago

They haven't thought it through enough.

[-] kautau@lemmy.world 14 points 16 hours ago* (last edited 16 hours ago)

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

[-] KingJalopy@lemm.ee -1 points 16 hours ago

In five billion years The sun will explode It's in the bible It's a fact

And no one will know That we were ever here It's a fact It's a fact

So rest assured in knowing That what you do don't matter Some one can do it better anyway It's a fact
