Keep in mind that on Earth-scale, movement through the fourth dimension would be pretty easy to notice. There's a lot of stuff on Earth, so seeing objects bounce in and out of view would be a pretty big deal.
But our universe as a whole is almost entirely empty space, with visible objects appearing to make up only about 5 percent of the universe's total volume. Noticing 4D things flit in and out of our 3D universe might be difficult at that scale.
- limomium 6y agoSo what about subatomic particle scale? Would it look like particles spontaneously appearing and disappearing? Quantum tunneling through obstacles? (they actually went around in another dimension)
- jayd16 6y agoI understand what you're saying but it doesn't make sense to me why this would be a rare occurrence. How could all the varied matter we perceive be so perfectly smooth and inertia free along the 4th dimension that we see no collisions resulting in movement along a 4th dimension?
