And, the angle of the (real, not your illustration) lunar reflector relative to the earth's surface is?
Before bogging yourself down with minutia, look at it logically. Here's a straightforward
gedankenexperiment:
Imagine both locations on the earth and moon have a retroreflector and a powerful telescope and laser. Each telescope is trained on the other's location, so everything its seeing is 1.3 (or, without rounding, 1.25) seconds in the past.
On earth we look through the telescope at the retroreflector on the moon, aim the laser directly at it's apparent position - and it would miss. The earth-based laser must be aimed
ahead at an offset from the lunar retroreflector's apparent position as seen through the telescope in order to strike it.
Yet looking through the lunar telescope at the retroreflector on earth, if the laser is aimed directly at it's apparent position -
it wouldn't miss. This is equivalent to what is happening in the LLR when the retroreflector bounces light directly back toward the source's apparent location and is detected.
That is a contradiction, an inconsistency, it makes no sense as there is only one path light can take from point A to point B... and yet the LLR experiment hinges on this contradiction somehow being true (actually it hinges on it being overlooked).
There are many other problems with LLR and modern cosmology in general and space
seance science in particular, other avenues which lead to understanding there is a nearly indescribable level of fakery and deception at play. This is just one that jumps out as being somewhat easy to begin unravelling. All that's required is willingness to look into the right rabbit-holes. BUT Most people just Won't want to wake up from the dream.
