How did the universe come into being? There are a multitude of theories on this subject. In a Physical Review Letters paper, three scientists formulate a new model: according to this, inflation, the ...

Superstring theory is not entirely beyond the reach of observation. It predicts a large negative cosmological constant and astronomers are pretty certain that the value is small positive. That's one ...
