Gravitational waves – Andrei Linde and InflationPosted: April 24, 2014
You might recall a gentle excitement reported in the news last month about a huge breakthrough in physics. The discovery being reported was the confirmation of primordial gravitational waves, which to be fair, may not mean much to you or anyone else not involved in cutting edge cosmology and physics. Even if you have little interest in the detail of the discovery and its implications I implore you to at least watch the first video below. It is the moment that Andrei Linde is surprised with the news that such waves have been confirmed. Linde was the physicist who initially proposed the idea of inflation (the huge expansion that the universe went through in the tiniest fraction of a second after the big bang) which is now confirmed by the discovery of these waves. Even if you dislike physics, watching a man and his wife receive confirmation of their life’s work is a genuine joy.
If that has whetted your appetite to understand what the fuss is all about then this video from Veritasium does a good job of explaining the discovery and why is is so fundamental to our understanding of the big bang and subsequently the universe.
