Time and space theories
[edit]I am sixteen and completely fascinated with time travel and quantum physics.Please dont disregard me becuase of my age. I have read a few books and numerous article on time and space. all of these say time and space are connected and most refer to time as the fourth dimension of space. my question is, has anyone ever proposed a theory that time is not connected to space at all, that time is not the fourth dimension of space, rather that time has its own set of dimensions? or perhaps space is actually a dimension of time? My second question is, if one takes away all ways to measure time, does time then cease to exist at all? If anyone has any information on these topics, i.e. books articles or whatever, i would greatly appreciate where to find them.
children are all knowing, we do not learn anything, only as we age do we remember what weve always known.

- All experimental evidence is that space-time has a Minkowski geometry - time is a fourth dimension, but does not act like the others because you cannot exceed the speed of light in any frame of reference. In consequence, you can't go backwards in time. Re. 'if one takes away all ways to measure time, does time then cease to exist' - within the context of modern physics, that is a rather meaningless question. You can measure time with three sub-atomic particles (perhaps less - but two doesn't seem enough to me), so time has meaning as long as there are at least that many particles in the universe - which had better be the case or your computer doesn't exist. Removing time from the universe isn't possible - it's equivalent to asking if space disappears when nobody's looking. I suppose that gets into such meta-physics as the observer effect in quantum mechanics and what counts as an observer. Your interest in physics should be cultivated, and I recommend Hawking's A Brief History of Time if you haven't read it already, but if you have questions not directly related to an article, please place them at the Wikipedia:Reference desk.
