They found that even though the Universe was producing stars at a much quicker rate about 10 billion years ago, it only used a minute fraction of the Universe's hydrogen and helium. Which means that although star production has decelerated down, it can keep going for a very, very long time.
The scientists also used the data to forecast that future Earths are more likely to appear within galaxy clusters and dwarf galaxies, which have yet to use up all their gas formaking stars and accompanying planetary systems. Our Milky Way Galaxy, instead, is all tapped out.
Planet Earth is in the first 8 percent, and who really knows what the next 100 trillion years, and the other 92 percent of livable planets, will bring. As the Space Telescope Science Institute puts it: "That's plenty of time for literally anything to happen on the planet landscape."
Literally anything, except us being around to see it L. The study has been issued in Monthly Notices of the Royal Astronomical Society.
