ALL the evidence shows our universe emerged from a single event: an eruption commonly known as the Big Bang.
What preceded that point is a mystery.
But it has significant implications.
It’s about the fate of our universe.
We know space is expanding. We can see that in the way all the galaxies around us are moving outward. But how far can it extend?
What happens next?
Will the universe merely boil away into the void as its component parts get further and further apart?
Or will it reach some kind of tipping point, where space turns around and begins to contract on itself?
The late Stephen Hawking had his own ideas. Now astronomers may have discovered one of the critical telltales that could prove his notions to be true.
