Our universe may one day be obliterated or assimilated by a larger universe, according to a controversial new analysis. The work suggests the parallel universes proposed by some quantum theorists may not actually be parallel but could interact – and with disastrous consequences.

Random quantum fluctuations mean the behaviour of particles and photons of light cannot be predicted exactly. The quantum equations that describe them contain a variety of different - and opposing - outcomes in their solution, such as a particular particle causing a bell to both ring and not ring in an experimental setup. Physicists then have to use an equation called the Born rule to calculate the probability of the bell ringing, and countless experiments have shown the rule works.
