Past the event horizon
When cooper was past the event horizon, but was still in his ship, the ship was starting to get bombarded with what appeared to be sand or some sort of particle.
It got me thinking…what if under that intense gravity, light waves - the photons, that act as a wave, are getting compressed into light/photon particles, which is what was bouncing off of Cooper’s ship, and ultimately what destroyed it, forcing him to eject.
When the gravity subsides, the particles “decompress” into a wave.
Is that what they were suggesting in that scene?
Just finished the movie for the 4th or 5th time. Man. It still hits hard.
