      Gravitational Waves at the Beginning of Everything

      Scientists from the Center for Astrophysics have found evidence of gravitational waves created mere moments after the dawn of the universe. These waves were created in a period of rapid expansion called cosmic inflation. This new evidence could prove the definitive confirmation of the inflation theory. It seems that finally, scientists can claim to understand the goings on at the beginning of everything. A Nature Video production.

      5 Essential Facts about Gravitational Waves from the Big Bang - The Countdown #44

      On March 17th, physicists with the BICEP2 experiment announced they had detected the remnant of gravitational waves in the cosmic microwave background, the light left over from the big bang. Although still needing confirmation, the discovery lends weight to the idea that the early universe underwent rapid expansion.

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

      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.
