The consensus on most college campuses is that over time the universe will become a colder and colder place. This consensus is constructed on two major observations:
- Doppler shift of light from the most distant edges of the universe suggest that it was still expanding at a great rate of speed when those distant celestial bodies emitted that light. Matter that expands, like gasses in an engines chamber or in a shotgun barrel, cools.
- Empirical evidence of mass transport out of our universe and into, presumably, parallel universes. Classic examples of mass export include black socks disappearing inside of clothes driers (aka, mass teleporters), silverware evaporating inside homes with small children and frying spam. Incidentally, the original Atom Bomb involved frying spam until it shrank down to anti-matter. It was a great plan but it took 30 hours to detonate.
I want to add evidence to support the small, vocal minority. College students are pikers compared to German Shepherd pups. Zeus demonstrated the ability to lap up two ounces of milk and produce four ounces of golden liquid in ten different, difficult to reach places.
If you wake up 17 quadrillion years from now and do not need to turn up the thermostat, you can thank Zeus.
