What happens when space expands? |
Is there more space or does space just get bigger?
Is space being created or is there just more space between the space?
Does the Planck length increase or are there more Planck lengths?

It doesn't really matter -- it comes to the same thing.
Is space being created or is there just more space between the space?
Again, it amounts to the same thing either way.

More Planck lengths.

More Planck lengths.
Thanks. Does this mean that theories which have quantized space are
implying that space is being created so that there are more space
particles, elements, or whatever they would be called?

This is known as the space-stretch in cosmology. This stretch also
stretches light; thus the cosmological redshift.

space is nothing
it does not sttrech does not contract - nothing!!
all the properties are in particles and if you dont mind
all particles has rest mass.
spare your precious time!!
(may be not precious ?? !!)

Whip The expansion of space gives galaxies more elbow room. Best
experiment to prove this is to bake a raisin bread,and watch it through
the oven window get bigger and bigger,but not the raisins Bert
