And what we do see is based on the light that was emitted or reflected by the objects in our environment, which entails travel time between the objects and the eyes and brain for processing and representing as vision.
Which means that the authors claim is wrong.
You’re rejecting the whole claim because you won’t allow yourself to see that there is no violation of physics. Light travels at 186,000 miles a second but light that is reflected off an object (the wavelength/frequency) does not become the pattern that takes on a life of its own. The object’s reflection is constantly being replaced with new photons but we are seeing that object now. If the object changes its characteristics, we will see this change instantly, not in delayed time. You keep thinking in terms of traveling (reflected) light that brings the past to us through space/time, which is why you’re unable to visualize how this works or that it even can work. I know this is hard. I hope you don’t give up.
We only see the object changing because it is either emitting or reflecting light. Without the light, we see nothing. Pitch black.
Quite simply, we don't see objects without light. The eyes detect light. That is their function. Easily testable, go into a dark room, flip the light switch......
