Are Early Galaxies Indicating a Future Dead Universe?

[Timboo]

If early galaxies are already dead and we see them then we seem to be in an age where we are heading for a dead Universe, in my opinion what do you all think?

In a sense we are. The concept is called heat death. It refers to the time when all the stars run out of fuel and stop shining.

But it won't happen soon. Estimates are up to 10¹⁰⁶ years (10 with 106 zeros after) for that to happen.

But in only 5 billion years or so, the sun will become a red giant and swallow the Earth. Hopefully, we'll move elsewhere before that happens, or our doom will come then.

I meant this article, shows it is happening sooner. Like it’s coming now

Yes, it is happening now, it will just take a while to finish. If my doom happens long after I'm already dead, it's not something that will upset me.

Nothing is coming to kill you. Star formation stopping in our galaxy wouldn't be a problem for us even if it did happen - our star is already formed and has about ten billion years left on the clock. And the most likely thing is that there's just something funny about gigantic galaxies in the early universe that makes them stop forming stars. Clearly star formation didn't stop everywhere - we're here.
