Okay, so uh
many, many, many, many, many times smaller than the diameter of a proton.
And
It is conceived of as sort of the physical limit.
Beyond which, things like quantum mechanics and general relativity
Don't work.
Okay.
So I
Right.
The math of uh
Right.
So there is nothing especially magical about the Planck length itself, except that our theoretical physics structure uh doesn't explain what happens before it.
Okay.
So a lot of what people are trying to do to figure out the uh origins of the universe, the Big Bang and so forth, is talking about that era.
It's often called the Planck time or the Planck era, when the universe itself had a diameter of smaller than that Planck length.
That there's a lot of uh really creative mathematical and physical uh thought processes going on to try to explain it because our existing
Quantum mechanics and general relativity do not apply very well and those smaller sizes.
So in that case, Brian O'Brien, I love saying that.
Brian O'Brien, I mean, what a guy.
Okay.
