There are parallel universes: Physicists state multiverses interacting

Academics are challenging the status quo of the single universe theory by claiming many different universes coexist and they all affect each other.  Professor Howard Wiseman and Dr Michael Hall from Griffith University's Centre for Quantum Dynamics, and Dr Dirk-Andre Deckert from the University of California claim parallel universes are a reality and influence one another through quantum mechanics.

The experts claim quantum theory is a necessity to explain the multiverse ideas, but recognise the late Richard Feynman’s quote, who once said "I think I can safely say that nobody understands quantum mechanics”. As such, they have taken a different approach in an attempt to elaborate on their theory.  The team have developed the ‘Many Interacting Worlds’ theory which provides a new prospective.

Professor Wiseman said: "The idea of parallel universes in quantum mechanics has been around since 1957. "In the well-known ‘Many-Worlds Interpretation’, each universe branches into a bunch of new universes every time a quantum measurement is made.
