New Big Bang evidence Also Hints That We May Exist In A Multiverse

The multiverse is the hypothetical set of infinite or finite possible universes that together comprise everything that exists and can exist: the entirety of space, time, matter, and energy as well as the physical laws and constants that describe them.

The first direct evidence of cosmic inflation - a period of rapid expansion that occurred a fraction of a second after the Big Bang - also supports the idea that our universe is just one of many out there, some researchers say.
