The Flat Universe?

19 Oct 2011

At ... it seems that in recent years cosmologists have discovered the universe is flat - or purportedly so. This is in spite of its apparent accelerating expansion. Why should it expand flatly? Why would the Big Bang be wholly one dimensional - why not spray outwards? The blame is being put on dark energy.

Over at the headline reads, 'Dark Matter mystery deepens' - and has a similar theme. At dark matter is likewise a mystery. The problem is that computer simulation models predicted it should bunch and clump together whereas in reality it does not appear to behave in such a way (paper published in The Astrophysical Journal).
