All 7 Dimensions Explained in Detail (From 0D to Infinity)

What would happen if a human body was dragged through the 0th, 1st, 2nd, 3rd, 4th, 5th, 6th, and 7th dimensions? In this science documentary, we explore dimensions explained visually - from a mathematical point with no size, to a one-dimensional line, a flat 2D world, our 3D illusion of depth, 4D spacetime, the block universe, branching timelines, many-worlds theory, and the idea of all possible realities. Using physics, geometry, Flatland-style thought experiments, coordinate systems, perception, time, and higher-dimensional metaphors, this video shows why our universe may be far stranger than it appears - and why the human brain struggles to imagine dimensions beyond the world we can see.
