Watching this was an hour very well spent. Delightful and informative.
I have always had a little difficulty fully comprehending a universe expanding away from us in all directions when we are not the center of it. This guy presented it in a manner that fully clarified the issue, and he is an entertaining and brilliant speaker. His "take" on dark matter and energy is fascinating.
