Thanks to Henson Shaving for sponsoring this video! Head to hensonshaving.yt.link/sV3xqyM and use code aperturethinking to receive 100 blades for free (2+ years worth). Just make sure both products are in the cart for the code to take effect.
Most people think of dimensions as directions. Left and right. Forward and back. Up and down. Maybe time, if they’re feeling generous. This framing is comfortable because it preserves the idea that reality is fundamentally stable, and that higher dimensions are simply extensions of what we already know.
But that assumption is completely wrong. In the next 30 minutes you’re going to question everything you thought you knew about the Universe. With each new dimension we explore, it’ll become clearer to you that the physical laws that bind us are not Universal. They’re local, conditional, dependent on the fact that we’re trapped in the 3rd dimension.
00:00 The Infinite Dimensions of Reality
00:59 1st & 2nd Dimensions
07:18 False Reality of Three Dimensions
05:54 Fourth Dimension
13:45 Fifth Dimension
15:43 Sixth Dimension
17:51 Eighth Dimension
22:36 Dimension 24
23:59 Extra Dimensions
25:27 Geometry After the Big Bang
27:07 Higher Dimensions Feel Unfair
29:16 The Double Slit Problem
32:26 Many Worlds & Branching Dimensions
34:38 Higher Dimensions Feel Existentially Unsettling
36:52 When Physics Actually “Breaks”
38:38 Stability Is a Byproduct of Confinement
