“The age and size of the Cosmos are written in light. The nature of beauty; the substance of the stars; the laws of space and time – they were there all along, but we never saw them until we devised a more powerful way of seeing. The story of this awakening has many beginnings and no ending.”
So begins the fifth episode of this season’s Cosmos, with host, Neil deGrasse Tyson.
This is a great episode to watch and share with your entire family and your entire school. Interesting historical and scientific background about optics and photonics, well told.
