So I get that a Planck length is the smallest length measurement that we have. But why?
I know it has something to do with gravity and speed of light in a vacuum. But why? Is it the size of the universe as early as we can calculate prior to the Big Bang? What is significant about it?
All the videos I see just say it’s a combination of these three numbers, they cancel out, and you get Planck length – and it’s really really small. Thanks in advance!

It’s the point at which our understanding and ability to do calculations within physics stops being reliable.
