The Speed of Light Reveals Something Strange About the Universe

Jul 12, 2026 Astrum Sleep Space
What would happen if you travelled near the ultimate speed limit of the universe? Spoiler: strange things start happening to space and time. This Astrum compilation explores the speed of light. Find out what the speed limit really means in 4D space, why it exists at all, and the strange ways light behaves when we’re not looking.

Alex Mccoan examines why causality has a fixed velocity through the lens of hyperbolic 4D geometry. By visualizing time as a fourth dimension and exploring relativistic effects like time dilation, this investigation challenges conventional perceptions of space, motion, and the way light interacts with the fabric of the universe.
