there are believed to be up to 11 dimensions, There is mathematical evidence to show the plausibility of more dimensions, but our human bodies are unable to sense 8 of those dimensions, more see in their direction.
We can only think of x,y,z, time is theorized to be one of the other dimensions, but we are only aware of it, I don't think you can point into the future or past, we are only aware of it.
But we cannot see past that, this would be like trying to draw a 2D stick figure standing up out of the page. And if that stick figure could think, it would have no concept. of what up and down were.
So extending this, we can be aware of this dimension but not physically travel through it, even though we constantly exist in it.
