Evidence Of Young Universe's Growth Spurt Is Discovered

Via Los Angeles Times:

Researchers focusing on gravitational waves find the first direct evidence for the theory of cosmic inflation, a faster-than-light expansion just after the big bang.

Scientists staring at the faint afterglow from the universe's birth 13.8 billion years ago have discovered the first direct evidence for the theory of cosmic inflation — the mysterious and violent expansion after the big bang.

The findings, made using radio telescopes at the South Pole, support the idea that our known cosmos make up just a tiny fragment in a much larger, unknown frontier that extends far beyond the reaches of light.

During this period of inflation, which happened just a fraction of a second after the big bang, the universe ballooned from smaller than an atom to 100 trillion trillion times its original size, at a rate faster than the speed of light.
