@Cardinal Am sure someone will post when fluther is going to die , tho i doubt that will happen .

In about 4 to 5 billion years when the sun goes nova and the born new red giant swallows the Earth and the other inner planets.

@AstroChuck ....that is if mankind doesn’t wipe everyone out by mistake.

AstroChuck's avatar

@mehmetaydin3- I didn’t say we’d be around then.

@AstroChuck BTW, recently you mis-spelled phonograph…............or did you? Am I the only one to appreciate your humor?

AstroChuck's avatar

No. I didn’t misspell it. What’s sad is mine is broken and I have all this porn lying around and nothing on which play it.

I have it on ultimate authority that the world will end in exactly…

Well, when one closes their eyes for the last time, that’s pretty much the end of the world for anybody, innit?

AstroChuck's avatar

Actually, I want to change my answer. I say the end will come when the San Francisco Giants win the World Series.

@AstroChuck Don’t forget the Cubs.

@jonsblond- True. It’s been a while since the Cubs won a series, but San Francisco has yet to win one so Chicago will get no sympathy from me.

Aethelwine's avatar

@AstroChuck Me either. I’m a football fan. :P

What do you mean by “world”? The universe? the earth? mankind? one’s own individual consciousness?

When rats can dunk

DrBill's avatar

In about 127,000 years.

That is when the Earth’s orbit will decay to the point that it will spiral into the sun.

People, people, people. Don’t you know the world has already ended? We’re just going along imagining it’s still around.

@AstroChuck – It will happen much earlier. The Sun is growing brighter at a rate of ten percent every 1.1 billion years. In one billion years’ time, as the Sun’s radiation output increases, its circumstellar habitable zone will move outwards, making the Earth’s surface hot enough that liquid water can no longer exist there naturally. At this point, all life on land will become extinct. See

But humanity will have ventured into space living on many Earth-like planets in our galaxy.

@mattbrowne- I only was referring to the end of the world (meaning the Earth), not its lifeforms.

ratboy's avatar

Just as soon as it’s finished.

mattbrowne's avatar

@AstroChuck – It’s still unclear whether Earth as a planet will or will not survive the red giant phase. There’s a chance that Mercury and Venus get pulled into the Sun, but Earth does not. In this case Earth will circle a white dwarf for hundreds of millions of years. The end of the Earth is then related to the decay of protons. Of course there are other scenarios. When Andromeda merges with our galaxy things could also get stirred up a bit.

Proton decay? How do protons decay?

mattbrowne's avatar

It might be a consequence of unification theories. The ranges seem to vary between 10^31 and 10^36 years. See

Recent experiments at the Super-Kamiokande water Cherenkov radiation detector in Japan give a lower limit of the proton half-life of 6.6×10^33 years.

Early grand unification theories, which were the first consistent theories to suggest proton decay postulated that the proton’s half-life would be at least 10^31 years.

wundayatta's avatar

The Wiki article said that proton decay has not yet been observed, so I don’t understand how the Super-Kamiokande water Cherenkov radiation detector can give us a lower limit of proton half-life. But then, there’s an awful lot I don’t understand, so this is not surprising.

mattbrowne's avatar

@daloon – Even without observation some of the hypothetical unification theories suggest the decay. More research is needed.
