ooh I get it.

The Moon is a projection of our universe, composed of elementary particles that manifest in a certain way and since the Moon "manifests" as solid atoms - someone can shoot up a laser-beam and recieve a reflected signal by one of the mirrors the US-Astronauts left on the moon. By calculating the time-delay between sending and recieving someone would know the distance (for t0).
In the "Reality-show" this is called "Causality".

So what we see in the world must be the results of all the vibrations and its manifestations from the "Reality-show". A "projected Reality" someone could say... but then we would have to define what is "real" first.

OP, is currently questioning the "Reality-show".. He believes the Moon is somehow a projection of "Reality" which is right under certain viewpoints.
Furthermore OP seems to believe the Moon is some sort of a "Hologramm" or at least it isn't the Moon from the past.
OP obviously believes in huge conspiracies, OP has become genereally skeptic about the "reality-show" and feels he can only rely on his own interpretations.
OP feels he must have somehow found the truth because he found correlation elsewhere.
OP reached a state of "inner-panic" where arguing with his mindset will be very hard.
OP temporarily ignores certain features of the "reality-show" because it conflicts with his beliefs. (In the reality show its called "denial".)

In other words, Truman is making a travel to himself.
