The Planck length is usually defined as the scale at which QM effects become dominant. This is what I am referring to.
I found one question, but that one has no good answers.
Now contrary to popular belief, space expands everywhere, and yes here where we are too. It is just that the matter that builds us up, and the things surrounding us, are held together by stronger forces, so space expansion does not expand us.
Now there come two theories to mind:
the Planck length is set to be relatively constant to the size of the matter that builds us up, like nuclei and atoms, this is what I see currently being the case
since the Planck length is the scale at which QM effects become dominant, and space itself is expanding, and space itself embeds the quantum fields, and its excitations, the elementary particles, as space expands, the scale at which QM effects become dominant, should expand too
Now I see some contradiction here. If space itself is the basis for the scale at which QM effects become dominant, then the scale should expand too.
- As space expands, should the Planck length too?
