Gamma Ray Bursters: Electrons, Anti-Electrons & Mass Exploding

[verdigris]

When an electron and anti-electron come together a gamma ray is produced.
So are gamma ray bursts just the product of lots of electrons and anti-electrons coming together? I gather that at least twice the mass of our Sun is required for a gamma ray burster to form,so if we have two masses and one mass is all electrons and the other is all antielectrons and these merge - what an explosion they would produce.Also,if several large charged masses were orbiting each other and gradually coming together we could get a longer duration of gamma ray bursting.And maybe supermassive black holes are just huge numbers of charged gamma ray burster masses exploding, but because of their really high gravitational pull,the gamma rays can't escape and stay in the supermassive hole.Surely nature is this simple?

Try Google for gamma ray bursts - there is a tremendous amount of information available.

When a positron (anti-electron) and electron combine in mutual annihilation, two gamma rays are produced, each roughly of 0.511 MeV, the rest mass of the positron and electron.

In the gamma-ray bursts of stars, the source is nuclear fusion reaction on a collosal scale. Looking at this spectrum -

- one can see energies in the MeV and GeV range, which indicates nuclear and possibly particle interactions beyond electrons.
