I haven’t seen anything about a negative cosmological constant… anybody got more info on that?
Edit: thanks for all the responses. Stuff has (of course) changed a lot since I took classes. I got some research to do

Oh boy is that scientists face gonna be red from embarrassment in 20.1 billion years when the universe doesn’t end. Just like all those other doomsday prophecies.

Not that we will be around for this, but it’s important to note this is just one of many theories and it’s based on dark matter. Recently other studies suggested dark matter might only be an illusion. https://phys.org/news/2025-10-dark-energy-cosmic-illusion.html

Waaaaiiit I swear the universe was supposed to expand forever. Has the consensus changed?
“It’s important to note that this is far from a certainty – **not a prediction**, but one possible future if the recent hints can be validated.”
„Reverse big bang?“ Did they change The Big Crunch as preferred science geek verbage?
If this were to prove to be true, it seems to suggest that the crunch would culminate in resetting the stage for yet another Big Bang to occur. Also the idea that objects could – in theory – converge/collide with each other without being “seen” as the contraction of space-time would potentially happen faster than the speed of light from one object reaching the other is perhaps more mind boggling than the opposite scenario. Not that any living being would possibly exist by the time the crunch reached such a state to actually observe that phenomenon.
So the theory that time is just circular is true? Universe collapses in on itself and then blows back out in a big bang for it all to repeat once again
Why is this being discussed like it is news?
The Nobel prize was awarded to experimental confirmation of this fact in 2011.
“Predict” here is really misused and misunderstood for effect. The authors predict the universe will come crunching down in the same way as I predict that clouds would taste sweet if they were made of cotton candy. It doesn’t mean I predict the clouds actually taste sweet, it just means that if the assumptions of the model are correct (clouds are made of cotton candy), which is to be tested by experiment, then it will taste sweet. Every scientific model has to predict something, whether the model is accurate or not. The proof is in the pudding (empirical observation).
