| − | It says that no theory has ever unified gravity with electromagnetism. While not proven, Kaluza-Klein theory was developed decades ago and does exactly this. One other thing is that it says e=mc^2 cannot be derived from first principles. Could someone explain what is wrong with current derivations.

Could someone explain what is wrong with current derivations. Also this part doesn't seem to make any sense. I tried rewriting it, but it was reverted and my addition put in a footnote, so I'm guessing I misunderstood it. |
