Environmental Outlook: Gravitational Waves And The Big Bang Theory
Physicists are calling the findings of a recent experiment that may have provided a glimpse of what happened an instant after the Big Bang “huge," "extraordinary" and "spectacular." Claims that scientists at the South Pole have detected signs of gravitational waves in the fabric of space-time are renewing hopes of finding a complete theory of how the cosmos began. Some cosmologists say this is one of the biggest discoveries in the field in 20 years. Others argue more direct evidence is needed. For this month’s Environmental Outlook, Diane and her guests discuss possible proof of the Big Bang Theory.
