@steve reid,
Quote: Well I'd have to say
My doubling of speed ends if the doubling would exceed the speed of light
Your halving of distance ends if the halving would be less than the Planck lenght
The Planck length might be the smallest measurement with any meaning to us in this Macro world, but when you consider a proton, which is a subatomic particle that forms part of the nucleus of an atom and a proton is around 10 to 20 times smaller than a Planck length and add to that, the fact that protons are not fundamental particles and are composed of smaller constituents called quarks and gluons, then the Planck length in this micro world no longer seems so small.
This universe began as a singularity and will end as a singularity, the gravitational condensation of the photons which are the quantum of the electromagnetic energy from which all matter was created, does not stop at the Plank length.
At the singularity there is no space between the photons, [NO SPACE] there is no Big Bounce.
Because three-dimensional time as we know it, does not exist prior to the Big Bang: from the return of the universe to the supposedly infinitely hot, infinitely dense and infinitesimally small singularity of origin to the next Big Bang when three dimensional space and time would begin, it would appear that no time had elapsed, thus [As I believe] the erroneous Big Bounce theory.

Three physicists say they have done calculations suggesting that before the birth of our universe, which is expanding, there was an earlier universe that was shrinking. To arrive at their pre-existing universe finding, Ashtekar’s group used loop quantum gravity, a theory that seeks to reconcile General relativity with quantum physics.
These two seemingly fundamental theories are otherwise contradictory in some ways. Loop quantum gravity, which was pioneered at Ashtekar’s institute, proposes that spacetime has a discrete “atomic” structure, as opposed to being a continuous sheet, as Einstein, along with most us, assumed. In loop quantum gravity, space is thought of as woven from one-dimensional “threads.” The continuum picture remains mostly valid as an approximation. But near the Big Bang, this fabric is violently torn so that it’s discrete, or quantum, nature becomes important. One outcome of this is that gravity becomes repulsive instead of attractive, Ashetkar argued; the result is the Big Bounce.
Paul Steinhardt of Princeton University, a cosmologist who has explored some related concepts, wrote in an email that the new research “Supports, in a general way, the idea that the Big Bang need not be the beginning of space and time.” The universe “may have undergone one or more bangs in its past history,” he added. Steinhardt and colleagues have also proposed a bounce of sorts, but it’s different. It could turn out that the two scenarios are equivalent at some deep level, but that’s not known, he added. Steinhardt‘s scenario makes use of string theory, another attempt to reconcile General Relativity with quantum physics. Some versions of string theory portray our visible universe as a three -dimensional space embedded in an invisible space having more dimensions.
There is no Big Bounce, like night and day there is a rest period between the Big Crunch and the next Big Bang.
“Universe after universe is like an interminable succession of wheels forever coming into view, forever rolling onwards, disappearing and reappearing; forever passing from being to non-being, and again from non-being to being. In short, the constant revolving of the wheel of life in one eternal cycle, according to fixed and immutable laws, is perhaps after all, the sum and substance of the philosophy of Buddhism. And this eternal wheel has so to speak, six spokes representing six forms of existence.” ---- Mon. Williams, Buddhism, pp. 229, 122.
