But what is the nature of the "perturbations"? Relativistically self-interacting knots/manifolds? Can you take the elastic medium and fold it onto itself (through higher dimensions?) in a manner similar to (but not the same as) a microscopic black hole to stabilize it into a particle? Either I'm going schizo or I should read some real books on the subject.

Apparently they're just the same stuff that light is - i.e. presumably this: https://en.wikipedia.org/wiki/Vacuum#Quantum_mechanics https://en.wikipedia.org/wiki/Vacuum#Quantum_mechanics As I understand it, the idea in the video is that if vacuum can be seen as non-linear elastic medium, then with the right functions for elasticity and stress, you can create conditions where EM waves at high enough frequency will hit the "sweet spot", a local minimum, where the energy gets confined in space by those non-linear properties, and can't leave without supplying additional energy. And such confined energy seems to behave like you'd expect particles to. Again, I am not a physicist, so I'm probably wrong in understanding what half of the words I used above mean. But I do understand the idea of multiple forces creating semi-stable states that are "energy traps". For instance, the balance between electric repulsion vs. attraction from strong nuclear force is what defines how tightly bound is the nucleus of any given atom (aka. the "nuclear binding energy"). The nucleus can't expand or split apart, nor can it contract, unless you supply additional energy. When you do - say, you hit a large atom with high-speed neutrons to break past strong force attraction, or smash two small nuclei together at high speeds to overcome electric repulsion, the other force takes over resulting in a rather spectacular release of energy[0] as matter finds new stable configuration. So I feel the idea here is similar, but with stress and elasticity in place of strong and electric forces - if there's enough energy propagating through some space, the wave gets trapped in a spatially-confined region instead of dispersing into the medium. -- [0] - https://www.marketbusinessnews.com/wp-content/uploads/2014/02/Nuclear-binding-energy-curve.png https://www.marketbusinessnews.com/wp-content/uploads/2014/0...
