Currently the expansion is still accellerating, so I don't think a collapse is going to happen anytime soon, if at all.

New theories about the ultimate fate of the universe arise all the time—and almost all of them fade into obscurity within months. I'm still going with Occam's Razor (i.e. the Universe will last forever, but will be rendered useless by the heat death). 80—90% (perhaps even more) is made up of dark matter and dark energy; I very strongly doubt that it will all one day contract.

I shall be dining alone at table 42 in the Restarant At The End Of The Universe.

I guess no one of you read the article. It's talk about a phase transition of the Higgs field that wold make particles more heavy, bringing the collapse of the Universe.

The article is a bit annoying because the author speaks as if he has never heard of the well known latest astronomical data showing that the universe expanding at an accerlating rate.

However if these equations are right then it implies that this accelaration in expansion that is being observed wont stop the future big crunch.

Further: it implies that there is no need to invoke dark matter.

Regular matter is enough to pull the universe back to a singularity because regular matter itsself will suddenly get a billion times more massive. You dont need extra unseen matter to apply the gravitational breaks to stop and reverse expansion.

But it's nothing to be upset about.

Its actually reassuring. The universe is running down and would need a big crunch to rewind it. And this is a way to get that big crunch.

And it wont happen before christmas. So dont worry!

I read the paper in arXiv. It is a statistical argument.

I will believe the collapse is underway when the various galaxies start heading in to a crunch point.

I've read the paper, and found it to be lacking in factual data - while the maths may imply a certain outcome, there is no vetted observation to back it up.

Interesting read, but it's certainly nothing to panic about.

The end of the universe is definitely nothing to worry about. We'll all be dead before the universe considers ending.
