There is a 50 per cent chance that time will end within the next 3.7 billion years, according to a new study. Some physicists believe that our universe - and everything in it - will continue to expand at an ever-increasing rate, splitting into newer universes as it goes.
This is known as theory of 'eternal inflation' and has spawned the idea of the 'multiverse' in popular science-fiction.
But a group of scientists have argued that the laws of physics do not work in a universe that is never-ending and continues to expand – it must end at some point. And Raphael Bousso, at the University of California, Berkeley, has worked out when this is most likely to happen.
His team’s argument is that in an infinite universe any event that can happen, will happen. Furthermore it will happen an infinite number of times.
The problem with this is that if there are an infinite number of instances of everything happening it is then impossible to determine the probability of them happening at all.
This means that the laws of physics, as we know them, no longer work.
