Will there be a day when the stars will vanish from the night sky?
WE USED TO BELIEVE THAT THE STAR WERE ETERNAL and the Universe was infinite and immutable, but we now know that this is not the case.
From vast clouds of cosmic gas, stars condense, ignite and burn themselves to death. Even the Universe had a moment of birth and one day it too will die. But surely, as long as there is a Universe to house them, there will be stars?
Maybe not. Could it be that, one day, mankind’s distant descendants will gaze at the night sky and see a starless carpet of perfect black?
A new study suggests that the best days of the Universe’s star formation are long behind it and that most of all the stars that will ever be born already have been and are now creeping into old age.
