My understanding of all this is that "space" and "time" does not exist. There is only quanta of energy (quantum field theory) from which we should be able to derive space and time. Which does not means there nothing smaller than planck length. But I learn all this by watching discovery channel so I would appreciate if somebody smarter can summarize idea that space and time derive from something else.
