Antonio, I centered this thread to be discussed by you (but everybody can psot if they want to).

I don't like the idea that time is a special dimension. Einstein didn't think time was special or anything, it's just one more dimension. The only thing is that we are not used to consider time a dimension, but we do change of speed in time (when we change in speed in space we do so in time).

What I mean is why is space in one 90º to time, if time is just as the other dimensions?

I don't mean by this that time should be at the same axis as space. What I do mean by this, is that each of the four dimensions (3 of space and one of time) should be at 90 degrees from each other. Imagen there is a total of 360. Then there is this:

UP-DOWN 90º FROM LEFT-RIGHT 90º FROM FRONT-BACK 90º FROM PAST-PRESENT 90º FROM UP-DOWN.....And it all starts again.

What do you think?
