Workings and Explorations of the Universe Part 1

(This)... "will require critical thinking on your part to start with the most basic observations assumptions of nature to develope a deeper understnading of why the 3rd rocky planet from a yellow star, in a spiral galaxy, in a nondescript part of the universe, has creatures upon it that ponder the meaning of life." (from Dr. Brian Murphy's syllabus: Spring 2009 AS102 Mordern Astronomy).

Light and Matter:

"I would say that light is not matter, and if a glass of water overflows when you shine a light on it, then odds are you bumped the table. Also note that in that experiment, if light were matter, then the water should continue to overflow until the glass is empty of water and full of light. Somehow I doubt that happens."

Physicists have for the first time stopped and extinguished a light pulse in one part of space and then revived it in a completely separate location. They accomplished this feat by completely converting the light pulse into matter that travels between the two locations and is subsequently changed back to light. http://www.physorg.com/news90077438.html
