+ - Dark Energy not necessary after all?-> 1

Submitted by ttnuagmada
ttnuagmada (1064148) writes "'Dark energy', which researchers have spent years trying to fathom, isn't necessary to explain our universe after all, according to a new solution to Einstein's theory of general relativity. This challenges the notion that dark energy makes up 76% of our universe, as many cosmologists believe."

Dark Energy not necessary after all?

  • Well, one of the problems with applying Einstein's general theory to cosmological problems is that the textbook version really doesn't work very well in that context. Einstein's implementation of a general theory was devised around the assumption that it'd have to reduce to special relativity over small regions, and as a result, it tends to come with some additional baggage that doesn't really work in the context of modern cosmology.

    Einstein originally constructed his general theory around the assumption

An optimist believes we live in the best world possible; a pessimist fears this is true.
