This video clip explains the different theories of multi-universes.
Things I learnt from this video clip:
- I learnt about the bubble 'universes' model A.K.A. baby black hole universes.
- I learnt about the membranes and extra dimensions (the Brane-world model).
- And I also learnt about the many worlds picture of quantum mechanics (the many-worlds model).
P.S. I'm sorry if I misspelled anything.
