Re: Pair Instability
There is going to be a black hole behind the expanding wavefront we're seeing now.
A Pair Instability Supernova is a supernova that doesn't leave behind a black hole or neutron star. The supernova is so violent that it obliterates the core before it can collapse into a black hole, therefore there is nothing left from which a black hole can be formed. Therefore if this is a pair instability supernova, there will not be a black hole.
