The Top 10 Space and Physics Stories of 2014

A spacecraft photographs itself approaching a comet in deep space

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. Here are my selections for the top ten stories from this year, with a look forward at what [...]

Shocked Physicist Learns His Big Bang Theory Is True [Video]

Andrei Linde Hears BICEP2 Results

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. Physicists announced this morning that they have discovered imprints of gravitational [...]

Merging Black Holes May Be Detectable by 2017

LIGO gravitational wave observatory

In his indispensable 1994 book Black Holes and Time Warps, physicist Kip Thorne wrote of the tantalizing discoveries that awaited in the coming century. In particular, the existence of gravitational waves—ripples in the very fabric of space and time caused by the motion, and especially the collision, of extremely massive objects—might soon graduate from theoretical [...]
