American theoretical physicist and string theorist Brian Greene discussed nine types of parallel universes (multi-verses): 1-The quilted multiverse works only in an infinite universe. With an infinite amount of space, every possible event will occur an infinite number of times. However, the speed of light prevents us from being aware of these other identical areas. 2-The inflationary multiverse is composed of various pockets where inflation fields collapse and form new universes. 3-The brane multiverse follows from M-theory and states that each universe is a 3-dimensional brane that exists with many others. Particles are bound to their respective branes except for gravity. 4-The cyclic multiverse has multiple branes (each a universe) that collided, causing Big Bangs. The universes bounce back and pass through time, until they are pulled back together and again collide, destroying the old contents and creating them anew. 5-The landscape multiverse relies on string theorys Calabi–Yau shapes. Quantum fluctuations drop the shapes to a lower energy level, creating a pocket with a different set of laws from the surrounding space. 6-The quantum multiverse creates a new universe when a diversion in events occurs, as in the many-worlds interpretation of quantum mechanics. 7-The holographic multiverse is derived from the theory that the surface area of a space can simulate the volume of the region. 8-The simulated multiverse exists on complex computer systems that simulate entire universes. 9-The ultimate multiverse contains every mathematically possible universe under different laws of physics.
