Evidence of other universes DEC 13 2010
Cosmologists have discovered evidence that our universe has been "bruised" by collisions with other universes.
Today, another group says they've found something else in the echo of the Big Bang. These guys start with a different model of the universe called eternal inflation. In this way of thinking, the universe we see is merely a bubble in a much larger cosmos. This cosmos is filled with other bubbles, all of which are other universes where the laws of physics may be dramatically different to ours.
The findings are currently difficult to reproduce, but with better data on the way, scientists are hoping to get to the bottom of the matter in the next few years.
