Photon Electron

[Little Bang]

Suppose that I had a small sphere made from a material that is a perfect reflector. It will reflect any photon no matter how high it's energy. Someplace on the inside of the sphere I have an antenna for injecting photons. I start injecting photons with as much energy as I can muster. When the energy density inside the sphere is equal to the energy density of a single electron is it possible that electrons and positrons start appearing, annihilate and reappearing to do it again and again?

My best guess would be no. But then I can't imagine anybody being able to set that test up in the first place, so what's the point of the question?

The point is that may have been something like the BB if matter could be created that way.

Little Bang: have you seen this NASA report ? http://www.dailygalaxy.com/my_weblog/2012/12/image-of-the-day-nasa-captures-earthly-anti-matter-explosions-video.html

 

A gamma ray (high energy photon) burst has been suggested with predicted energy E = 511,000 ev that resulted from collision of electron (e-) with positron (e+). Gamma ray bursts with extreme energy have been observed and are believed to be very soon (matter of milli sec) after Big Bang event and it does appear such high energy bursts of 'photon' energy can result in production of both electrons and antimatter positrons. So, perhaps your 'perfect reflector' is the inner most boundary of a Black Hole, the 'space' of the Black Hole, for 'space' is nothing more than the inner most boundary of that which contains.
