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.
