It is important. Based on a lot of comments, people seem to think "oh, well, universe dead, I guess." Which is far from the truth. There are still millions of galaxies forming millions of stars, and that is going to continue into the indefinite future. This is saying that statistically, the younger the universe, the more stars that are created. And they bright, hot, short-lived stars, that, once dead, will give birth to many new stars (who will also generally be bright and short-lived, just less so). This means that the universe produces a great deal of young stars shortly after its inception, but that eventually gives way to many more long-lived stars that are actually habitable for life. The universe is very much in its hayday, right now. We're living evidence of it.
