Hey, I'm kinda confused...

So electrically charged particles constantly emit photons. What's their wavelength? And how is it possible that they emit like really many of these all the time, but for example when an electron and a positron are annihilated, there will be only two gamma ray photons?

If a neg and a pos particles exchange photons, why can't two positives as well? What's the difference between electron and positron? What exactly makes one negative and the other positive?

@Mostwantedo These are VIRTUAL particles. They have all possible wavelengths, and they disappear before they violate the uncertainty principle restrictions. Two positive particles DO exchange virtual photons -- this results in the repulsive force that they "feel".

This is an introduction. It is good, but not for me. My theory is that we started out as a jet and are accreting into a disk. The center of the universe isn't the origin of it's existence, but the location of the axis normal the jet emitter. And we may be flitting away from the source like a forming smoke ring, meaning the center axis might not point directly at the source even though it was caused by it.

@BlueDemeter One theory is that membranes in higher dimensions are essentially slapping each other causing big bangs within, maybe even multiple big bangs at a time. Another theory is that the big bang happened as a quantum fluctuation.

Hot and Fast!

@flamingo0123 It should, since this is all nonsense. The universe is far easier than generally assumed.

@antipoti Why? Its a massive load of BS.

[Nomasain]

@BlueDemeter It's good to remain sceptic. To me this video is full of BS.

does he have boobs?

@gwendance that's not part of the standard model. dark energy, dark matter, antimatter, asymmetry, super symmetry, extra dimensions, quantum gravity, wormholes, micro black holes, etc. are all separate topics.
