One of the most startling scientific discoveries of recent decades is that physics appears to be fine-tuned for life. This means that for life to be possible, certain numbers in physics had to fall within a certain, very narrow range.

The most popular explanation for the fine-tuning of physics is that we live in one universe among a multiverse. If enough people buy lottery tickets, it becomes probable that somebody is going to have the right numbers to win. Likewise, if there are enough universes, with different numbers in their physics, it becomes likely that some universe is going to have the right numbers for life.

    From wikipedia: “The universe is all of space and time[a] and their contents,[10] including planets, stars, galaxies, and all other forms of matter and energy.”

    If not everything is in it, we dont call it a universe. Simple.

      The multiverse is the hypothetical set of all universes.[a] Together, these universes are presumed to comprise everything that exists: the entirety of space, time, matter, energy, information, and the physical laws and constants that describe them. The different universes within the multiverse are called “parallel universes”, “flat universes”, “other universes”, “alternate universes”, “multiple universes”, “plane universes”, “parent and child universes”, “many universes”, or “many worlds”. One common assumption is that the multiverse is a “patchwork quilt of separate universes all bound by the same laws of physics.”[1]
