space to go to next dimension and press a to switch to 4d aThese are two tesseracts, you can see them from all directions, as a 4th dimensional object can be seen from all possible directions at once, take a regular 3D cube we can only see it from one angle/direction at once and there is depth, now with a fourth dimensional object (in this case a tesseract) it can be seen from all directions at the same time. We live in the third dimension but dimensions can have dimensions in them. in the third dimension (ours) we have the 2nd, and 1st dimension inside it The same goes with the fourth dimension the third, 2nd, and 1st dimension are inside them and so on and so fourth. So basically dimensions have every lesser dimension inside them that is the basics of the fourth dimension.
sorry my bad i meant that the 4th dimension is where you can see all of the angles of an object, say you are on the fourth dimension and your looking at a wall you would see the inside corners of thee wall from any angle and it would seem like the object is moving but the 4th dimension for us is time so you're seeing the object from every state it has been in and will be in press space for next dimension 1st is 2d, second is, 3d fourth is 4d. press a for tesseract also the first dimension is essentially just a line
