This is just a note to myself, really. Author’s knowledge, if you like, but if you find it useful, that’s even better.

The Planck Scale: The Boundary Where Physics Breaks Down

At a certain scale, reality stops—it doesn’t just slow down or get weird, it completely stops.

There exists a physical boundary so small that below it, our standard concepts of distance, position, and existence itself cease to carry any meaningful definition. What makes this scale truly staggering isn’t just that we cannot see it; it’s that we have mathematical proof that something is happening there—something our two best theories of the universe are explicitly forbidden from agreeing on.

Welcome to the Planck scale.
