How do we know whether or not light is actually bouncing off everything, versus light excuding out of everything? Maybe there is some sort of signal that comes from a light source that tells matter to emit photons instead of bouncing off?
Maybe it's the inverse of what we generally blieve?
for example an apple is seen as Red because other colors are "absorbed", and red is reflected. So what if it's not reflected, instead it's emitted? It only emits the red because some signal is telling it too, once the signal is cut off, it immediately stops emitting?
