The 50 cent tour says because of the uncertainty principle, there is still activity at absolute zero temperature. And since you can't get a good handle on the mass of a particle if you know exactly where it is and vice versa, it means (and has been proven as something real) that particles flash into and out of existence in an extremely short span of time.
Google "Casimir effect' which shows a small non gravitational effect pulling two sheets of matter together at sufficiently close distance due to an effect whereby matter tends to wall off the generation of these particles so between the plates there is a smaller number of particles coming into and exiting existence than the space outside the sheets so there is a gentle push trying to close the distance between the sheets.
This effect was predicted by Casimir decades ago but was just experimentally seen a few years ago due to the difficulty in isolating all the forces involved, like electric, magnetic, gravity and so forth.
Here is a Wiki about it, nice graphics.:
