What Was Happening Before the Big Bang? w/Brian Greene | Joe Rogan

Summary by Krater

Brian Greene discusses the origins of the universe, cosmic inflation, and repulsive gravity on The Joe Rogan Experience, suggesting that the Big Bang may have been triggered by repulsive gravity in an early chaotic universe.

Answers: What happened before the Big Bang?

• cosmic inflation
• origins of the universe
• repulsive gravity
• Einstein's equations
• dark energy
• cosmological models

What it concludes

• Einstein's equations allow gravity to be repulsive as well as attractive.
• Uniformly spread energy throughout a region of space yields repulsive gravity.
• The expansion of the universe is currently speeding up rather than slowing down.
• Repulsive gravity in an early chaotic universe may have triggered cosmic inflation and the Big Bang.
