One day the sun will die

[MagentaRocks]

For some reason I wondered what would happen if the sun dies. I looked it up and it turns out that the sun is half way through its life and it will die, by getting hotter and burning itself out in effect. It will also swallow the earth. It is likely to be a billion years before life on earth is wiped out - as the sun gets hotter the water around us will boil etc but it feels really weird to think that one day there will be nothing and no life anywhere.

I think I have freaked myself out during lockdown!

By then we’ll be on another planet and life won’t exist as we know it. It does make me sad though to think that all the stuff in the earth like bones, fossils etc will be gone : (

@sandpapercourtisan 🤣🤣🤣🤣

Bobbin I always wondered why Buzz Lightyear said 'To Infinity and beyond'! I used to tell my students we were part of some string theory replay with all our descendants looking at us.

I must admit to getting the collywobbles when I think about stuff like this; you can see why some people turn to religious belief (and that's from an ex RE teacher veering towards the atheist end of the spectrum).

Dont forget that super volcano in one of the national parks. Everyone will die when that erupts

Yellowstone, yep, that will be Dinosaur apocalypse take 2.

Its all talk anyway. Everyone knows we are characters in a huge Sims game.

The universe is always expanding... does that mean it ends somewhere? But then, what’s beyond that? Nothing? What is nothing? It hurts my head thinking about this stuff too much

Yellowstone is due to go off sometime in the next 500,000 years. When it does, life in most of N.America will be wiped out.

There is also a big precipice hanging off a Canary Island which when it goes plop is going send a tsunami to engulf New York City and points south.

Yep, just like every other star.

Love this post 😁 Totally on my thought process wavelength 😁

That's not good! Yellowstone is phenomenal though, probably the most amazing place I've ever visited, glad it decided not to erupt while I was there.

Could be tomorrow...

Just saying.

You can just see Trumpy boasting that now he has the biggest volcano. The best ashcloud...

...and as I was saying

La Palma, Canary Islands:

@MagentaRocks you need to read about the Fermi paradox waitbutwhy.com/2014/05/fermi-paradox.html

Super interesting

I'm old enough to remember Surtsey forming off Iceland #irrelvant .

We'll be long, long dead by then.

@Brahumbug If the universe is infinite, then there are infinite identical copies of you out there on identical planet Earths

But whyyyyyyyyyyy?

The set of integers is infinite, but there aren't two identical integers.

This reasoning has pissed me off ever since I was seventeen. To be fair, the most annoying part was that the next part of the argument was "and somewhere out there is a you who's being horribly tortured" and the celebrity on the tellyprog went "oooh, I don't like that idea, obviously the universe is finite" which GAAAAAAAAGH

(I think it was Steve Davis, but that may have been a different programme we watched in physics. This infinity one is suggesting Noel Edmunds to me but I don't know whether that's just lockdown-fever brain)

It's supposed be about 5 billion years before the hydrogen at the core is exhausted but what is more concerning is that in about 600 million years the CO2 levels on Earth won't be able to sustain trees or plant life and so they will die off, taking many animal species with it.

600 million years....hmm, I think I'll still sleep tonight!

At least his boasting is likely be short lived....

In any given Hubble volume of space there is a huge but finite number of particles. There are a finite number of combinations of those particles, just as there would be a limited number of ways you could arrange a pile of Lego bricks. Given a large enough volume of space then the combinations must repeat, after about 10 to the 10 to the 122 meters. Have a look at the work of Max Tegmark for a much better explanation.

OP - there is a video on youtube about the death of the universe. That’s quite a fascinating watch, especially as we’re still in the earliest stages of the universes life, according to the video. Can’t remember what it’s called, saw it a few months ago.

Try this TED on it - short and sweet. There was a BBC doc a while ago about it too.
