From the video
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.
