Series of experiments could shed new light on the ‘multiverse’
WHAT IS THE MULTIVERSE THEORY?
The term ‘multiverse’ was invented in December 1960, by Andy Nimmo, then vice chairman of the British Interplanetary Society.
It is based on the theory of eternal inflation, which suggests that shortly after the Big Bang that formed the universe, space-time expanded at different rates in different places.
According to eternal inflation theory, this gave rise to bubble universes that may function with their own separate laws of physics.
The idea of other universes out there may seem strange, but scientists say it can help solve some problems of fundamental physics.
For instance, the long-standing mystery of why nature appears to be fine-tuned for the emergence of life can be explained by the picture of a multiverse.
Some scientists argue that intelligent observers exist only in those rare areas in which the conditions happen to be just right for life to evolve.
The rest of the multiverse remains barren, but no one is there to notice it.
