ANN ARBOR, Mich.— Why is the universe magnetized? It’s a question scientists have been asking for decades. Now, an international team of researchers including a University of Michigan professor have demonstrated that it could have happened spontaneously, as the prevailing theory suggests.
The findings are published in the Jan. 26 edition of Nature. Oxford University scientists led the research. (more…)
The theory that our universe is contained inside a bubble, and that multiple alternative universes exist inside their own bubbles – making up the ‘multiverse’ – is, for the first time, being tested by physicists.
Two research papers published in Physical Review Letters and Physical Review D are the first to detail how to search for signatures of other universes. Physicists are now searching for disk-like patterns in the cosmic microwave background (CMB) radiation – relic heat radiation left over from the Big Bang – which could provide tell-tale evidence of collisions between other universes and our own.
