Okay, so it’s a clickbait title. Sue me.
But the fate of the universe is hanging in the balance!
You see, in recent decades the reigning scientific cosmological theory, the Lambda cold dark matter model (Lambda-CDM for short), has suggested that the physical universe started with a Big Bang that was so energetic that the universe will keep expanding forever, resulting in the eventual heat death of the universe—a “Big Freeze” in which matter and energy are so thinly spread throughout such a vast space that everything is cold and dead.
Sounds grim. And a lot of people don’t like it. That’s why there is considerable excitement about new findings suggesting that the universe may have a very different fate. You can read all about it in this article from BBC Sky at Night Magazine:
“The Universe may end in a ‘big crunch’ after all,” by Ezzy Pearson and Chris Lintott
“Big Crunch” is the nickname for the idea that eventually the universe will stop expanding, and will start collapsing in on itself again until everything comes together in a singularity, which is an incredibly small hot dense state like the one that existed just before the Big Bang. This would open the door to the possibility of an oscillating universe, in which the universe goes through an ongoing cycle of expansions and contractions, one after another, like pearls on a string. A lot of people like this idea much better than the idea that everything ends in the dead, dead death of the universe.
So which theory is right?
