The point I’m making is somehow we might be able to use quantum physics to detect the light as it is traveling away from us without being in the direct path of the light.
A regular telescope catches incoming light. Instead, we would “quantum radar”, if you will, the light as it is leaving. As we get better at doing it we might be able to focus in more and more.
Think of it this way. If I shoot a laser into space with a solid red beam visible to the naked eye, then we will see a beam only. But, that beam has an end point. We definitely are NOT able to outrun the tip of a laser beam, but we might be able to somehow detect the photon path it is traveling in space.
Or, If I shoot a lazer into space how long can we see its tail? 0 seconds? Once it departs it is untraceable until it bounces back from a mirror?
It’s like shooting outward a needle of light into a sea of incoming light and trying to keep track of it. Surely, it is cutting a quantum pathway into spacetime, and maybe we can only “watch” it leave very briefly for now.
Just think if we could use quantum wave information to pluck our patterns of light out of space, and reconstruct even a totally blurred image of ancient Earth.
I think it’s within the realm of possible.
