In the philosophical system of Metaversalism, the Metaverse (sometimes also called the Omniverse) refers to the abstract realm consisting of all mathematically precise, consistently describable objects/structures/theories.
Person A: "Did you know, from your own subjective point of view, your consciousness can never cease to exist."
Person B: "Why is that?"
Person A: "Because no matter what happens to you, there will always be some possible world in the Metaverse in which you continue existing. If you no longer exist here, then you will only find yourself there, in those universes."
One particular term often used to characterize any hypothetical future form of the Internet. Coined by Neal Stephenson in the book "Snow Crash".
