Astronomers have found that the rate of star birth is 30 times less than it was 11 billion years ago.
What this means is that the vast majority of stars that will exist in the universe are already here and that we will only likely see a maximum of five percent more in the future. The more time passes, the slower star formation becomes. The discovery lends credence to the idea that in billions of years time we could be looking at a cold, dark universe in which all the stars have burnt out.
"We are clearly living in a universe dominated by old stars," said study leader David Sobral. " All of the action in the universe occurred billions of years ago."
In its youth, the universe was a roiling soup of star ingredients, with new stars forming rapidly. But now it’s much quieter, and things are not expected to get more exciting anytime soon.
