Creditable theories of quantized space?

Question

Are there any creditable theories of space being quantized like energy and time (Planck time)?

Answer 1

There are credible theories, but nothing yet to tell us what it's really like at that scale, and what it would mean for space to be quantized.

Answer 2

There are many physicists who ascribe to the theory space-time is quantized, now referred to as quantum foam, or space-time foam. It was first proposed by John Wheeler in 1955 as the foundation of the fabric of the universe, and to provided a description of subatomic space-time turbulence at distances of the Planck length.

I'm hoping when the LHC cranks up to full operation we may embark on a journey that will turn physics on it's head, just as Newton did to ancient physics, Einstein to classical physics, and quantum theory to the understanding of the ultra small.
