A Whole Spectrum of the Universe

[Hitchcoc · 9/10 · 12 July 2014]

This episode tells us that something overlooked by Newton could have led to the great science of astrophysics had he been just a bit more perceptive. He was investigating the light spectrum of basic sunlight, but didn't take it to the next level. It was discovered a hundred years later that all substances in the known universe are made up of the same elements. Once this was established, we could begin to define planets, stars, solar systems, galaxies, and other cosmic phenomena. Tyson takes us into a field of flowers and talks about light absorption. He talks about the many kinds of light, including microwaves and x-rays to see how the common objects of our lives can glisten with new being, given the proper instrumentation. This was a great episode, explaining something that I knew of but never understood.

Try to give too many messages

Light in astronomy is all but that message was lost between too much social commentary and pretended scientific method explanation.
