Depending on what you think reality is, maybe the universe below Planck´s scale does not exist. If for you reality means what can be observed, then you can say the universe below planck´s scale does not exist, the universe would end in the planck´s scale. That why planck´s lenght sometimes is defined as a quantum of space, and planck´s time a quantum of time. Space and time would not exist in scales smaller than planck´s scale, but obviuosly for that you must assume that reality is only what can be observed.

Thats very interesting Atlantis, it gives a certain mystifying effect if you try to think about how vast things really are if you take into consideration what cant be observed.
Some infinities can be considered bigger than others if one defines a particular set of values for a given infinity. As another example (in addition to Hilbert's Hotel), consider a circle with an infinite radius as opposed to a sphere with an infinite radius. Obviously, the sphere represents a "bigger infinity" because it includes a 3rd dimension absent from the circle.
"True/Absolute/whatever-adjective-you-fancy" Infinity is another story. By definition, it is infinite in all and any values, therefore nothing can be "bigger."
