DO YOU KNOW WHAT HAPPENS WHEN 2 STARS COLLIDE?
ONE OF TWO THINGS:
They merge together to form a new, larger neutron star, or they collapse into a black hole.
The moment a pair of neutron stars collides and collapses into a black hole,
they're emitting a blinding gamma ray burst across the galaxy.
It shines at gamma ray frequencies with such intensity,
that it can be detected even at distances of up to 10 billion light years,
which is close to the edge of the visible universe.
