The title of this video is "When will time end?"
This video describes the theories that scientists have had over the years about time.
I have learnt that
- Entropy, based on the second law of thermodynamics, holds that states of disorder tend to increase, from neat orderly starting points, are all headed to states of high entropy or disorder.
- Nature fight entropy by constantly rebuilding (reassembling) matter and energy into lower lower states of entropy in cycles of death and rebirth.
- Stars shine because gravity crushes matter into their cores.
