thanks for that. i appreciate that u can only really get to grips with the sub-atomic world by understanding the mathematics which describe particles and forces but it is still interesting to know which phenomena are well understood by science and which are not. please don't let my ignorance...

Can't say I really follow what's been said so far (thanks for trying) but I was just wondering, has anyone ever postulated a charge equivalent of the Higgs particle or are you all satisfied that charge is intimately linked with quarks and electrons without any need for an external field. Also is...

thanks for responding but perhaps i should have mentioned I am not a physics graduate so i need an explanation in layman's terms although i appreciate that translating concepts in particle physics into everyday language is often difficult/impossible .

to the untrained eye electrons and protons seemed to be very different, different size, mass and composition but they have the same quantity of charge (ignoring the sign). why is this? An even more fundamental question: what is it about an electron or proton which gives it its charge in the...

thanks for the speedy reply . so is it true to say that nearly all, if not all, modern rockets accelerate to a speed higher than the exhaust velocity?

i was having a discussion with a friend recently and he seemed to think that you cannot accelerate to a speed which is faster than the speed of the accelerating force coming out of the back of the rocket. but i thought it was the case that u could get to very high speeds in space even if you...
