LIGO Livingston Observatory An investigation by the LIGO Scientific Collaboration and the Virgo Collaboration has significantly advanced our understanding of the early evolution of the universe. Analysis of data taken from 2005 to 2007 has set the most stringent limits yet on the amount of gravitational waves that could have come from the Big Bang in the gravitational wave frequency band where LIGO can observe.
