Heat Death
Last night I was reading the New Scientist's article on photographing black holes, particularly the one presumed to be at the center of the Milky Way. I then took off on a Wikipedia spree in the following order:
- Solar System
- Milky Way
- Galaxy
- Dwarf galaxy
- Great Attractor
- Dark flow
- Timeline of the Big Bang
- Universe
- Ultimate fate of the universe
- Heat death of the universe
