Many scientists talk about how our universe has 4 dimensions of space-time; the 3 physical dimensions we see, and time, our fourth dimension. This is a theory I don't understand and personally think it is majorly flawed and illogical, since these same astrophysisists then talk about the theory of how the gravity of the planets, stars, and everything else in space creates a warping effect in the "fabric of space-time". This warping is not something visible to the naked eye, so it is not in the 3 dimensions we percieve, and it is also not time itself being warped, so it isn't in any of the 4 dimensions talked of. This means that for this warping to exist wouldn't there have to be at least five dimensions? I am just wondering what you think of this, and how many dimensions you believe space has. Also, for those who know what the string theory is, I am wondering what your thoughts are on that, as I know of it, but don't really get it.
