Scientists Discover The 'Smoking Gun' For The Big Bang Theory
Following the Big Bang nearly 14 billion years ago, the universe began to expand. In a conference that took place this past afternoon, scientists announced that they now have direct evidence of this event.
The primordial cosmic microwave background radiation that continues to spread through space to this day holds the key to this ancient event.
Using the South Pole Telescope and the BICEP instrument, scientists detected gravitational waves in the universe’s fossil radiation. Even more amazing, they also found that the telltale polarization signals are much stronger than expected.
Physicist Marc Kamionkowski, at Johns Hopkins University, said about the discovery:
“If these results hold up...then we’ve learned only that inflation has sent us a telegram, encoded on gravitational waves and transcribed on the cosmic microwave background sky. It will be essential in the years to come to follow through with more detailed and precise measurements to infer fully what this telegram is telling us.”
Lawrence Krauss, a theoretical physicist at Arizona State University, said that the discovery, if verified, "gives us a window on the universe at the very beginning."
"It's just amazing," the AP quoted him as saying. "You can see back to the beginning of time."
