We're going to focus on questions where you can't learn the answers because they're unknown.

First of all, the 100 billion galaxies within range of our telescopes are probably a minuscule fraction of the total. However, recent theories in physics, including one called string theory, are now telling us there could be countless other universes built on different types of particles with different properties, obeying different laws.
