History of the Universe
We still dont know how physics works in this era yet. We have some idea, but dont know for sure how the universe is going to end yet. The observable universe We know whats going on base on
- ur knowledge of
physics

Inflation and Gravitational Waves
SLIDE 11
What are Gravitational Waves?
SLIDE 12
- Space-time tells matter how to move
- Matter tells space-time how to curve
- Gravitational Waves: Ripples in the fabric of space-time
- Black Holes: The final fate in the collapse of matter
Einstein’s Theory of General Relativity
