I’ve not read it yet, but it’s supposed to be new.  Link also goes to some other potentially interesting looking articles.

I read the link and the abstract, but not the paper that it is reporting on. The Big Rip predicts that accelerating expansion will result in the ripping apart of objects and particles, ultimately into their tiniest fragments of energy composition. The mathematicians who wrote the paper have extended the time line before the Big Rip might occur, and have cast some new doubt on the current age of our big bang universe as well, but in the grand scheme of things, this is not a significant finding IMHO, and doesn't take into consideration any possible interruption to the rate of the accelerating expansion, like bubble nucleation or something of that sort. It does lend some support to Einstein's curvature of space, but changes some of the details that have been used to predict the age of the universe.


You also mentioned some other interesting looking articles, and I took a look at this one: https://www.laboratoryequipment.com/news/2016/12/dark-matter-decreased-big-bang?cmpid=horizontalcontent


It should be true that there is less dark matter now than at the big bang. The article doesn't try to explain why, but I would be interested in participating in a discussion of some logical reasons, if someone were to start a thread in the NewTheories sub-forum (I won't hold my breath, lol).
