A video clip that caunght my attention

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.
