swanneOtherwise you'd have to put up with Zeno's paradox[...]
Zeno's paradox was solved rigorously centuries ago.
Aristotle (384 BC−322 BC) remarked that as the distance decreases, the time needed to cover those distances also decreases
Today there is still a debate on the question of whether or not Zeno's paradoxes have been resolved.
We can (and do) have that and still know perfectly well that space is not quantized in any way.
The Planck length is about 10−20 times the diameter of a proton, and thus is exceedingly small, it is considered the smallest length possible, see quantum foam.
And so space, may be that nothingness, the canvas on/in which all something exists. If this is not true, that there is no such thing as an area of nothing, that all that exists is modes of something, meaning space/vacuum is somethingness, a type of energy or matter

We already know that energy and matter are the same thing

My guesses at the image:
-Time is the rate at which form reacts to information.

So if a particle has the property of a wave, while it is a wave, it is still a particle? If so, I understand perhaps a single discretely valued quanta, turning into a wave like object, while energy and all is conserved, and so in a way you would say yes even when a particle becomes a wave "its still that particle" just in a different form? Is a photon an electromagnetic wave? Or electromagnetic particle?
I personally tend to lean towards the idea that space its self is the "nothingness" in which all energy exists.
But how does energy arise within an infinite sea of nothing, how is it possible to get something from nothing? Quantum mechanics shows us that even a completely empty vacuum is fluctuating with vacuum energy.
mbkennelHow is this known? Is there clear experimental disproof against any such kind of theory or only certain classes of such? (and what are they?)
When you say "quantized" do you mean some kind of analog to having a non-zero commutator?
ImaFungiSo your criticism of my responses have been due to your belief that space is infinitely divisible? Meaning that if you touched your two fingers together there exists an infinite amount of space between them? The same infinite amount as if you held them two inches apart? and as infinite as the distance between two galaxies?
ImaFungiTo put my thoughts on this more simply. Are all the fields that exist physically in reality quantized?
Does this disprove loop quantum gravity and if so is LQG dead?

Yes, any discreetness of spacetime would cause the speed of light to depend on wavelength (very high energy light would travel at nearly c, and lower energy light would travel at less than c).
I was thinking along these lines when I said I don't know on page 1, but if this has been settled I'd like to learn more about it. Any references you care to share on this?
"The brief answer to this question is, 'Nobody knows.' Certainly there is no experimental evidence in favor of such a minimal unit. On the other hand, there is no evidence against it, except that we have not yet found it.

ArbitrageurDoes this disprove loop quantum gravity and if so is LQG dead?
And has this determination been made since 1999 when this article was published which seems to indicate uncertainty on the topic of quantized time?
Is time quantized? In other words, is there a fundamental unit of time that could not be divided into a briefer unit?
I also found his lectures entertaining.

Just dig around for Haramein, N. (2012). Quantum Gravity and the Holographic Mass.
His seminars are mind warping as well. When you find the papers and seminars, should link them in. I would, but like I said, I've done it so much, I look like a Fanboy!
The seminars are actually really really entertaining, from the ancient archaeology stuff to the physics.
