A Multiplicity of Universes: Fact or Fiction
A multiplicity of universes, the multiverse, is a fashionable concept that has become increasingly popular in connection with the fictional world of superheroes. There is however a physical (as in Physics) base to it. Arguably, it all started in 1957 with the publication of Hugh Everett's thesis "Theory of the Universal Wavefunction" (check out Many-worlds Interpretations and also The Many Worlds of Hugh Everett III: Multiple Universes, Mutual Assured Destruction, and the Meltdown of a Nuclear Family). Some links about this work:
Parallel worlds, parallel lives
Interview: Parallel lives can never touch
Hugh Everett: New film tackles "many worlds" theory of quantum mechanics
BIOGRAPHICAL SKETCH of HUGH EVERETT, III
Are we closer to a 'theory of everything'?
Mathematically speaking, the idea is connected to Hilbert Spaces (see, for example, Hilbert Spaces With Applications, Introduction to Hilbert Spaces with Applications or Hilbert Spaces, Wavelets, Generalised Functions and Modern Quantum Mechanics). Universes can split but they cannot merge. The entire concept is not time-symmetric and it is linked to quantum gravity (see, for example, Euclidean Quantum Gravity, Foundations of Quantum Gravity or Knots and Quantum Gravity). It also contradicts Special Relativity (see, for example, Relativity: The Special and the General Theory or Introduction to Special Relativity). Very speculative work indeed, but... hard to prove wrong! The stuff of Science Fiction. Do we live in a multiverse?
