How can a person 32.5m light years away possibly see any trex photon from 65m years ago ...The photons have long shot past their planet, yes?
T. rex photos starting their trip 65 million years ago would reach a persoj 32.5 million LY away after 32.5 million years, arriving 32.5 million of our years ago. If that person captures the photons and converts them to an image displayed on an extremely precocious Samsung big screen, then the photons from that screen would take another 32.5 million years to get back to us, meaning it gets here right now.
I can do some calculations and tell you how big the aperture of any telescope that can theoretically resolve a T. rex, or the image of one On a Samsung, 32.5 million light years away, would need to be, but that's another story.
