dimensions

we know the uses of dimensions.certainly as they are there,we are there. if we would have lived in 1 dimension space then we would have moved in one direction and we would have become flat

2] if we would have lived in 2D space then we would have gone back and forward but not up and down

3] as we have live in more than 2D including 3D we can move up and down.

4th dimension and 5th dimension are geometrically different and astronomically different

in space 4th dimension is of time.i want to state that why cant waves be the 5th dimension of space. note- i mean the em waves. we cant go with the sound as sound needs a medium of transmission in space--- solid/liquid/gas. but EM waves transmit without the need of medium

we say space is 3d with time 4th d. but every body in space has tendency of transmitting em waves either the paticles of alpha,beta,gamma

the dimensions can be called as the sides of object. now according to this defination, EM waves though are'nt the real sides of object but we can say they come out from the edges. likewise time goes with space so, it is a part of space like wise the EM waves are a part of cellestial objects..
