Can spin foam models of LQG handle high-energy particles?

It may be a simplistic question, but i wondered if the spin foam model
of LQG could survive a particle of 10-20 Mev ripping through its matrics.

Surely if the spin-foam model is accurate (and remember, it is mostly used at present as a form of path integral), then the zipping macroscopically envisioned particle would be when viewed microscopically some kind of wave propagating zig-zag fashion through the foam. Particles after all would be in the foam not somehow or other prior to it.

Thanks for reply SelfAdjoint.

It may sound strange that space time could be harmed in any way,
but as far as i know everything in nature is degradable, in one way
or another, so is ST indestructible?

I prefer a different analogy. Spacetime is malleable, but resilient. It accommodates any transaction that does not violate causality [e.g., the laws of thermodynamics].
