A Brilliant Physicist Explains Gravitational Waves to Colbert

We all read that thediscovery of gravitative waves was a really crowing deal , but do you really realize what they are , why they ’re important , or how LIGO , theLaser Interferometer Gravitational Wave Observatory , establish them ? After watching thisbrilliant spot from last night ’s The Late Show with Stephen Colbert , you will .

Theoretical physicistBrian Greene , who ’s also known for books such asThe Elegant Universewhere he explain conception like string hypothesis in layman ’s damage , was on the show last night to give Stephen a crash course on not only why gravitative waves are important , but also how they were discovered .

Greene even live so far as to break out a really dandy experiment take green lasers that replicates how the LIGO observatory works , but on a much simpler and little scale . If at the end of this magazine you still ca n’t enfold your head around gravitative wave , it ’s probably best to just go out that research to the professionals .
