Our home – our planet, our Solar System and indeed our entire Universe – has a finite lifespan. All that is will be destroyed, either in fire or, as observations suggest now seems more likely, in a lingering, depressing ‘heat death’. The stars will all go out, and the expanding cosmos will be no more than a colossal, black and freezing void in which nothing of interest ever happens again. The laws of nature insist upon it.
Interesting thought experiment on the inevitable demise of our universe and how it could be saved. I’m always fascinated by reading about the vast scale of the universe and the fact that we still know so very little about it.
