Why can’t we get smaller than the plank length?
In: Physics
As a theoretical, of course you could. You could have a half Planck, right? Theoretically, you can divide any number in half… in reality, though, we don’t do that.
In practice, it’s meant to represent the smallest feasible distance. It’s the distance light travels in a Planck unit of time, which is the smallest unit of measurable time. With these values, we can have the smallest divisors to work on quantum mechanics and other very small maths.
It’s a real thing, but for most of us, it’s used as the “infinitely small” distance or time.
