Question: is this the only universe

Hi Travinator,
Interesting question!
Many scientists have theories on this subject, one man Hugh Everett III (google him) has a a theory he calls “many words”; stating that many universes exist. He believes each time we make a choice, the universe splits into parallel universes, and we actually make all of the possible choices we could have made, in different worlds, although we are only aware of our choice in our own world.

Everett’s theory involved a quantum mechanics notion called “superposition,” which basically says that a particle, such as an electron, can exist in billions of positions at the same time, but when measured — when observed and interacted with — it shows up only in one position. Everett said the person looking at the electron clones his or herself once for each of the billions of possible positions the electron could be in. The person will exist in multiple universes.
As I said Everett isn’t the only science with these theories but for the moment we do not have any definitive proof.
We can’t be the only universe out there, I’m sure one day we will have prove.
