Woops - ah well I shall continue in here: I have read some theories of a 5th dimension on these forums but none of them agree with my theory. I shall try and explain it as plainly and simply as possible. I propose that a 5th dimension, is the Matter itself. Assuming we have four dimensions already - length, height, width and time. (X, Y, Z, T). Ok - time does not seem, to most people, to define a location in space as the other dimensions do - yet those locations must exist for a certain amount of time to be definable in the first place. Hence if one is to assume that time is a dimension - then it seems that the Matter itself must also be considered a form of a dimension. None of the others could exist without time, just as without the matter itself being present - nothing could exist. Length, Height, Width and Time all exist within Space (some argue that space and time are one in the same in this form). It is that Space, which is the Matter. Thus, 5 dimensions: X, Y, Z, T and M. Some may argue that X + Y + Z = M. This is not true - for X + Y + Z will only define a location. We must somehow incoorporate M into the equation. The matter itself must first be measured and identifyable. For this, I am hoping some of you more experiance physicists out there will share their views I know this concept is highly controversial, so I shall be prepared to argue any points made by any skeptics among you. Thank you, Chris Scerri
