Why do we care how many universes there are and how they’re arranged?
- We want to know!
- It would be amazing if there were multiple universes.
- The soft anthropic principle is most satisfying if there are many universes with different properties.
Why do we care how many universes there are and how they’re arranged?
Question: Is there a reason the universe is the way it is, or is it just arbitrary?
A few of these attributes are: number and topology of dimensions (like space is 3-dimensional, not 2- or 4-dim), conservation of energy (energy can’t wax and wane, either arbitrarily or according to some rule), four forces and their properties (why not more or fewer forces; why gravity not both attract and repel, electricity only attract, etc), has the particles w/properties that it does.
