Brian Cox: 'Multiverse' makes sense
The presenter and physicist Brian Cox has said he supports the idea that many universes can exist at the same time.
The idea may sound far-fetched but the "many worlds" concept is the subject of serious debate among physicists.
It is a particular interpretation of quantum mechanics - which describes the often counter-intuitive behaviour of energy and matter at small scales.
Prof Cox made the comments during an interview with Jim Al-Khalili for Radio 4's The Life Scientific programme.
