[SPACE] GBH composed of e-/positron?

I'm maybe missing something here but what's stopping the electrons and positrons from annihilating? As far as I can tell, the author is treating them both as identical particles for the purposes of calculating degeneracy pressure.

The article looks otherwise OK to my (admittedly superficial) understanding but I just don't get the assumptions its based on.

I would guess that time dilation is stopping annihilation.

That only works if you magically will the whole thing into being. I mean, it wouldn't stop time dilation. It'd still be the largest bomb ever that's already exploding, but it could take a few hundred billion years for that explosion to actually expand from so near Rs.

Fortunately, there is no such thing as magic. So one needs to figure out how one of these came into existence.

1) The body consisted of ordinary matter that somehow decayed to e±. Well, nothing else will have nearly the same degeneracy pressure, so it would have collapsed before it'd have the chance. Not to mention, decay to e±, by whatever process, would be influenced by same dilation.

2) An e± cloud condensed into this body. That would annihilate long before it got to that density.

So either way, an e± cloud is an impossibility, making the paper a mathematical curiosity at best.

You had the chance to chew up their math, anyway don't waste your time, i agree, omg, 100%, damn thats scarey.

oh and we still cannot see what goes on below the event horizon.

Hmm... Wouldn't a light source from near Rs be redshifted ? Maybe we should look at very long wavelengths, such as ELF....

That being said, it's better to think that it's just mathematical curiosity. I mean, an universe with it's density being the critical density is pretty much the largest blackhole there could be :P
