If I were to hazard a guess as to the origin of what we call quantum foam I would go with it being a product of the expansion of space, the act of expansion on any point in space giving that point time-like properties momentarily. Any-hoo, thought I would put this up for anyone with other thoughts on the nature of space suds.

I don’t do that sort of request sorry!
I’m gonna say that aerogel stuff but held together with super strings in 10 dimensions.

Sounds like the “creator” was some kid in creche!

“Commander Ray Ford: On April 26, 2013 the FDA issued a drug safety communication warning the public that the anti-seizure medication Potiga can cause blue skin discoloration and eye abnormalities characterized by pigment changes in the retina. FDA does not currently know if these changes are reversible.”

I don’t know exactly what physicists mean by “quantum foam”, but consider that a point particle cannot exist as it must have an event horizon. If instead of a blackhole structure, one considers a wormhole structure, and also consider virtual particles, then this would a give space (or perhaps spacetime) a foam-like structure.

Not unlike what I was thinking when I posted this…. “Makes gravity sound like the opposite of spatial expansion to me, which kinda suggests the two are an elastic effect of particles effectively evicting there space-like qualities and I guess space evicting it’s time-like qualities.”

However, the way I see it is that spacetime and any notion of spacetime structure is a classical concept, and at the scale being considered, does not apply.
I think the critical issue is that the unobserved reality is different to the observed reality, so that even the direct observation of a foam-like structure does not imply that the unobserved space has a foam-like structure. This may explain why zero-point energy has a much lower effect on the curvature of spacetime than the obviously erroneous calculations indicate.

Would that effect be closer to the calculations if gravity and expansion were factored in as zero point effects?

Gravity, as a classical phenomena, is a mathematical consequence of the curvature of spacetime associated with energy-momentum in much the same way as the electromagnetic field is a consequence of charge-current. Although gravity and energy-momentum are distinct, they are mathematically inseparable. The expansion of space may be a consequence of zero-point energy, but as far as I am aware, nobody knows how to calculate the effect of zero-point energy on cosmology (calculations that have been done have been so wrong that the underlying theory can’t be regarded as even remotely close to the truth).
I think a big part of the problem may be that people find it difficult to grasp the consequences of counterfactual indefiniteness.
Counterfactual indefiniteness is THE notion that prevents general relativity from applying to the quantum realm.

What does “equal and opposite action” mean in quantum?

The best answer to this question is the Ward-Takahashi identity:http://en.wikipedia.org/wiki/Ward-Takahashi_identity which is the quantum equivalent of the conservation laws of classical physics.
