What would happen if we consider Energy as Dimension ?????
on other way can we consider Energy as Dimension ???????

In relativity, energy and momentum are sometimes treated as a 4 vector, similar to treating space and time as a 4 vector.

Some related structures: the "mass shell" and "relativistic phase space".

I main by Dimension that why we do not consider that object move in spacetimeenergy dimensions ????

You can regard energy as being one of the states of a system, which makes energy a part of a phase space
http://en.wikipedia.org/wiki/Phase_space Motion is usually regarded as a change of position with time, so it would generally be the wrong word to describe the rate of change of energy with time, for instance. (A possible exception would be in the context of some phase space of which energy is one of the variables, one might then talk about motion in this abstract phase space).

i was actually thinking about this while i was pondering over superstring theory, and was surprised at how this would fit into the superstring theory.
As we all know, superstring theory tells us that the universe is made up of fundamental blocks of vibrating strings of energy. And that the frequency of the vibration of these strings determine the physical composition of the particle or sub particle. And for each positive vibrating string, there is a counterpart of it (antimatter). Now, we also know that there has to be a total of 11 dimensions (10 space and 1 time) in order for the superstring theory to work (a possible 12th dimension has emerged recently) and that these dimensions are in the form of a theoretical shape called the CalabiYau shape (the reason that we cannot see these extra dimensions is because they are so minute. Imagine you were holding a piece of paper from afar. It would seem like it only had 1 dimension, length; but if you were small enough and you climbed onto the piece of paper, you would actually find out that is it in fact 3 dimensional, length, width, thickness). And the strings travel through these shapes, and the vibrational patterns of the string is also determined by the CalabiYau shape. Which leads on to the exciting part. As we know, we cannot create, destroy or alter any dimensions. And we also know that we cannot create, destroy or alter energy. We may be able to change the FORM that energy travels through, but not alter it. Now, if energy was a dimension, then the vibrating strings would be a dimension as well. And since they are the fundamental blocks that create this universe, it leads us to believe that they are the fundamental dimension of the universe. For example: Since that energy is our first and fundamental dimension, a string that it creates would be seen as a two dimensional object; and this has been proven by theoretical calculations (since it cannot harvest any 3 dimensional properties and isn't a 1 dimensional object); and these strings form subparticles, which later form particles, then atoms etc. which are all 3 dimensional objects. I am still working on this theory, and I know it is an utterly mad idea, but aren't most good ideas, mad? Anyways, this is just my point of view. I'd be glad to hear some rebuttals =).
