| continuation:
We can't say how many dimensions the universe has, because these two reasons:
1) we are inside the universe, and so, can't see it (we can see other amtter and understand the 4d, we can see the reactions and way of behaving of energy and know its 3d.....)
2)if it were to have higher dimensions, we would probebly don't "percieve" them with our eyes or senses: we are reduced to 4d.
So the universe could be 5d or 6d, but we will probably never know. |
