in particle accelerators, we've seen the electromagnetic force and the weak force unified. How? Do W+, W-, Z, and photons dissappear, to be replaced by another fermion, or what?

Back to SetAI in post #3 I'm not asking how many dimensions we have thought about, I'm asking how many dimensions have been proven to exist scientifically. You can think about all the dimensions you want, but if only four dimensions really exist, what good is all your guesswork? The...

i've seen talk jof 4d, 5d, 10d, and even 26d space when talking about string theory. Have any experiments been conducted to show those extra dimensions exist, or are the extra dimensions just theoretical; just the best explanation for the behaviors of particles and strings we've observed in...

i've seen talk of 4d, 5d, 10d, and even 26d space. Have any experiments been conducted in these extra dimensions, or have any experiments been conducted in 3d to show these dimensions exist? Or, are these extra dimensions just the best existing explanation for the quantum force of gravity?

how do strings exist in our reality? Let's just say, for the purposes of this argument, that a string was broken and stretched until it was perfectly straight (i understand this could never actually happen). That filament, then. Would it exist in one, two, or three dimensions?

okay, the electromagnetic force affects antimatter and matter oppositely. (and I'm just guessing the same could be said for the electroweak and weak forces as well.) Now, does gravity affect antimatter the same way it affects matter? Or, maybe i should say, does gravity act as a repellant...

thanks for all the replies, fellas. But tell me something, has GPS or laser technology ever been tested at relativistic speeds?

How do we know the speed of light is constant? If the behavior of light can be described by particle theory, and if the perceived speed of a non-light particle is affected by the relative motion of the observer, then it doesn't make sense to me how light is always observed to have the same...
