"maybe particles just correspond to particular structures in the network. Maybe all that has to exist in the universe is the network, and then the matter in the universe just corresponds to particular features of this network"
Space and particles being equivalent is an old idea (knots in the ether type of old). Haven't seen much talk about particles being compression of space though so that might be somewhat new.
Clara Moskowitz said something quite interesting a few years back:
"It turns out that in Einstein’s theory of general relativity, regions of space with positive energy actually push space outward. As space expands, it releases stored up gravitational potential energy, which converts into the intrinsic energy that fills the newly created volume."
I've been wondering about the mechanism (how space could compress and decompress) as we don't really see energy being destroyed anywhere. But energy does go into "hiding" when you transform it into gravitational potential energy. So maybe that's one way how energy transforms into free space.
