The Universe as an Experiment.
18:06 - 27:35 (09:28)
The way physicists tend to think of the universe is like an experiment on a table; the planet, which is a giant thermodynamic system, must respond to the trigger of excessive energy use to create a large scale civilization. Climate change cannot be avoided because it is a natural reaction, not something to be prevented.

Summary
The complex technological society might not survive the shift to a new state caused by pushing the climate too hard, warns the speaker. Newton's laws of gravity also come into play in this context.

Physicists have a problem with the fine-tuning phenomenon.
21:14 - 23:02 (01:47)
Summary
Physicists have a problem with the fine-tuning phenomenon. Their solution, the anthropic principle, suggests that we just happen to live in a mediocre universe that supports life, but there could be other universes that don't.

Summary
The Kardashev Scale is a theoretical model that categorizes civilizations based on their energy usage. A Type one Civilization would be capable of harvesting all the energy from its home planet.
