difference between universe and multiverse
Answers
A Universe is everything which has been and will be observable from a certain point. For example, we cannot currently see the outer edges of our Universe, but some day we may be able to. In general, our Universe is seen as being either the shape of a sphere (traditionally) or a regular dodecahedron[1] (a twelve-sided polyhedron, hypothetically). We cannot travel outside our Universe, and it expands no faster than the speed of light.
A Multiverse is the concept that there are more than one Universes. Perhaps they would be parallel, and an identical copy of you or me would be reading Quora in another Universe, just as you are now. Additionally, encapsulated within the Multiverse theory is the idea that new Universes are being formed continually, which increases the odds that a Big Bang would indeed form our universe at some point in time. It would even be possible that there were different dimensions across the Multiverse, and physics behave much differently in the different Universes.
An Omniverse is a set of all Universes. Thus, the Omniverse may only include our Universe, or if there is indeed a Multiverse, it would include those as well.
An easy way to think about this is by looking at the prefixes:
Uni means 1.
Multi means more than 1.
Omni means all.
The only difference between 'UNIVERSE AND THE MULTIVERSE' is
A SINGLE is called Universe ( Uni means 1) and MANY are called Multiverse.( Multi means Many)
