Very interesting video. I think it's possible to bend the waves with perpendicular fields at the right frequencies. However, you could also make an absorption through cancellation. They do this for noise control and to drop temperatures with lasers. I haven't done this, but it's conceivable you could both read the rays coming in and counteract them with out of phase light/sound. I don't know about all that other mystical stuff, but you never know. There are layers of missing knowledge, for sure. These people were high level smart, and it would be interesting to have conversations with them. Too bad they are gone now.
