The limitations of the human brain mean some of the biggest mysteries of the universe may never be solved, a top scientist has claimed.
According to President of the Royal Society Lord Rees, questions about the big bang and the existence of parallel universes may be never be resolved because of the built-in limitations of mankind.
Lord Rees told The Sunday Times: ‘A “true” fundamental theory of the universe may exist but could be just too hard for human brains to grasp.
‘Just as a fish may be barely aware of the medium in which it lives and swims, so the microstructure of empty space could be far too complex for unaided human brains.’
Lord Rees’s prediction has been prompted by the failure of scientists to reconcile the forces that govern the behaviour of the cosmos with those that rule the ‘microworld’ of atoms and particles.
