Reflectors reflectors reflectors. OK now I am getting suspicious.
Are you trying to say that their are bright visible lights coming
from the moon, that cannot be explained by any means at our disposal,
except to pretend that we have scattered reflectors all over the
moon, such as on the edges of craters etc?
Just in case anyone is confused by this, we're talking about
retroreflectors (like the cube corners yachtsmen use to reflect radar)
that were placed on the Moon to reflect pulses of laser light fired from
Earth.
Only a very few photons are reflected, far too few to see with a
powerful telescope, but with the right sensor and knowing exactly when
the pulse was sent, you can measure the distance to the Moon to less
than an inch.
