Why Does QM Use Complex Numbers? Imaginary Time.

Explore how imaginary time—a mathematical sleight of hand that transforms black hole geometry into something more tractable—became central to our understanding of quantum mechanics and what it might reveal about reality itself. Discover why physicists from Minkowski to Hawking reached for complex numbers to solve some of the universe's deepest puzzles, and what that tells us about the nature of space, time, and the fabric of existence.
