I was pondering the exact same thing as I was watching the show,
but the theory got blown away by the end of the show, as it was
revealed that GRB's are not produced by supernovas ( not powerfull
enough for the distances involved) but what may be termed
hypernovas (30X+ larger). If I got it correct the result is not a
neutron start, but a black hole.

As Bart would say "Whoa Mamma!"
