This may seem small (barely visible as a dot to the naked eye), but that's also the geometric mean of the Planck length and the diameter of the observable universe. So average size actually.

I really can't follow your comment and I've been trying. Would you mind a longer explanation of what you're getting at here?

They mean 125um = sqrt(a*b), where a is the Planck length* and b the size of the observable universe (I didn't verify). Implying, 125um is some sort of middle ground. *Often said to be the smallest length with physical meaning.

Ok, so it's a bullshit comment. Thank you. You could say this about everything that is not 'Planck length', it's about as useful as Douglas Adams' 'the universe is empty' (only he had a sense of humor).

Oh, even worse they are repeating it in different threads.

Sure!

It was a joke :)
