No, this makes zero sense to me. It also doesn't make sense to me that mass and energy are equivalent, but if we take photons and try to make electrons out of it, somehow we end up with a different spin. It also doesn't make sense to me why we shouldn't be able to make matter from energy...

Well.. doesn't the sum of this series 1-1+1-1+1-1... equal 1/2 according to mathematics?

Yes, thank you. That was exactly what I was thinking too. Well, those and the 4 dimensions of spacetime. Or don't we need those? Because again, if that is the case, what is then the difference between these 4 dimensions and these 4 forces? Is the difference purely semantics, to better explain...

Such as? Standard model. Does that qualify? If not, then what theories exactly do you mean? (If this is about the fact that I posted in 'beyond the standard model', that is solely because on similar forums where I have posted in the past, general models were for serious questions about...

So, I have some questions regarding 'dimensions' and 'parameters' in physics. (there are differences in the meaning between physics and mathematics, as far as I understand it) ---- As far as I understand it, we live in a 4-dimensional world, consisting of 3 space and 1 time dimensions. Yet we...
