The universe of the film starts with a bang. In this universe, time is relative, and the events of the universe happen before anything. The universe of the film is a single, vast, interconnected system of space/time. There is a Big Bang, with an infinite number of subsequent events that occur, and a beginning. This universe is infinite and connected, it doesn't exist in isolation like a bubble on the surface of a pool of water. Instead, all the matter and energy of the universe is interconnected. The universe is a vast ocean of interconnected space/time, just like a giant pool of water. There are many different universes within the same universe, which can be seen as multiple universes within the same system of space/time. Each universe has a different set of laws, and these are not necessarily the same laws as in our universe. For example, the universe of the film contains no gravity. The universe of the film may contain no time. The universe of the film may contain no space, and so on. The nature of these laws is a topic of debate. Each universe has its own unique set of values, and these values may be the same as in ours, or the same as in our universe, but their relationship is not known. For example, our universe contains our values, and the universe of the film contains values, but the values in our universe are different than those of the universe of the film. A very simplified representation of the film universe: The Big Bang happens, with an infinite number of universes that are connected through space/time. The universe of the film is only one of these universes, and this universe is connected to a very small number of other universes. All these other universes are connected through space/time, just like the film. This infinite number of universes in the film is connected to just one universe in ours, and this universe is connected to just one universe in ours. This one universe is the Big Bang, and it causes an infinitely many different events in the universe of the film. Each event within this universe happens before the one before, so the events within the universe of the film are not "in the film" - they exist in a separate, but still interconnected universe. The Big Bang is infinite, connected and has its own set of laws. The value "1" is the value in the film universe, and this value is identical to the value contained in the film universe, but it is not identical to another value in this film universe. For example, in the film universe, the value "2" is identical to the value "2" in our universe, but the value "1" is not identical to the value "1" in our universe. The value "0" in our universe does not exist in this film universe, and is an "in-film" value.
