What the hell are you talking about? The only time the density of the universe was close to a Planck density of 1 (~5.1 × 10^96 kg/m^3) was about 5 x 10^-44 seconds after the Big Bang (according to modern theories... which I thought we didn't accept around here).
As far as "planck particle pairs" (which has nothing to do with your link, btw; just a rambling psuedo-scientific jumble attempting to piece together disparate snippets of "scientific" discussions), you are obviously confusing two separate ideas. A planck particle is a hypothetical particle, and one with an exceedingly small lifetime (1 x 10^-44 seconds and an even smaller size (1 x 10^-20 the radius of a proton). No one can give a convincing account of how we could detect such a particle... much less any evidence of its existence. As for a virtual particle pair, these are a well accepted feature of modern physics, but, outside of a few obscure and infrequent events, basically average out to a vacuum.
So, in other words, you seem to be repeating terms you have heard somewhere, but don't have the slightest clue what they mean...
You are confusing the assumed density of nuclear matter soon after the assumed big bang with the planck density of planck particle pairs (ppp).
The concept is that space itself consists of ppp (positive and negative) that are recombining and releasing energy as the universe contracts from the initial expansion, hence the source of the ZPE. The ZPE (which is an enormous amount of energy and has been measured as increasing), in turn, generates virtual particles that impede c through space. As the ZPE has increased since creation through the recombination of ppp, the number of virtual particles has increased, slowing c.

The link discusses ppp. How can you say it has nothing to do w/ them? Perhaps you are the one who is confused.

Yes, virtual particles are a well-accepted feature of modern physics and ppp are used to explain the ZPE. How do you explain the ZPE?
