The universe will develop ceaselessly and turn out to be ever cooler and darker, and finally all that will probably be left glowing very distantly from one another will probably be these red dwarf stars that final for trillions of years.

Supermassive black holes are more likely to be the final reservoirs of matter in all the universe. But even they’ll finally evaporate. Credit score: NASA/JPL-Caltech/Judy Schmidt.
Hello people, tune in each week of 2023 for the very best in astronomy from Astronomy Editor Dave Eicher, delivered to you by Celestron. Dave’s weekly video collection will cowl all the most recent sky occasions, scientific outcomes, overviews of cosmic mysteries, and extra!
This week, we’re speaking about one of many greatest questions in all of astronomy: How will the universe finish?
For a very long time now, we’ve identified by experiments and observations and satellites that the universe started 13.8 billion years in the past with a Huge Bang. For many years, nevertheless, there was a contentious argument about how the universe would finish: Would there be sufficient mass to halt the enlargement of the universe, collapse again to a singularity, and have possibly repeated Huge Bangs?
Right now, the evidence leans in a single course: The universe will expand forever and turn out to be ever cooler and darker, and finally all that will probably be left glowing very distantly from one another will probably be these red dwarf stars that final for trillions of years. And finally we’ll have a really chilly and darkish and quiet place that may come to a cease. Scientists name it the warmth demise of the universe — or extra colloquially, the Big Freeze.
Nevertheless, scientists can’t but fully rule out that risk that the universe’s enlargement could one day come to a halt. Both approach, don’t fear — that’s many trillions of years sooner or later.
