A second 'Big Bang' may be what ends the universe
The standard model of particle physics may be wrong about our universe dying slowly.
So would the death of a star or some other catastrophic event be needed for this to occur? Scientists don't think so.
According to them, all it would take is the destabilisation of the Higgs boson - or the God particle - which is thought to give all matter its mass.
Process could have already begun
What would follow is an explosion of energy that would destroy everything in the universe. But this shouldn't happen for trillions of years based on their models.
However, researchers also say that the process could have already begun. So what might cause the collapse of the god particle?
Professor Ruth Gregory of Durham University suspects that the curvature of space time around a black hole might instigate the collapse.
But without knowing where the Higgs boson is in our infinite universe, there's no way to know if the event has already occurred.
