From humanity’s first, flawed foray to the surface of a comet to the celebrated discovery of (and less celebrated skepticism about) primordial gravitational waves, 2014 has brought some historic successes and failures in space science and physics.
Few people were as thrilled with the big physics news today as physicist Andrei Linde. One of the main authors of inflation theory--the idea that the universe expanded incredibly rapidly just after it was born in the big bang--Linde has reason to be excited.
If we live in a multiverse, then Where Is Everybody Else?
The imprint of gravitational waves created shortly after the big bang may offer direct evidence for inflation theory, according to a discovery by the BICEP2 experiment at the South Pole
