so um lasers lasers are great because it proves that we went to the moon oh oh yeah so how does
that work so there's something called retro reflectors on the moon did you know that who
put them there uh neil astronauts neil neil armstrong now i don't know who put them there
astronauts they put it they put them there you could shoot a laser at a at a retro reflector
and it will reflect back and no matter where you shoot on the on the mirror because it's like have
you ever seen like the corner of like a bathroom mirror like you could you you could see it like
but imagine i'm four ways yeah so that's what you could shoot it from any direction and it'll come
back to you yeah i'm saying yeah that's that's what's on the moon so if you shoot a laser at the
moon and you hit the retro retro reflector at any angle and you should be able to get that same
frequency light back back in the same position yeah and if if you're just hitting the moon and
it's like a reflective surface or you know people say stuff like that it would it would uh it would
come back at a different frequency but it hit a mirror whatever right yeah yeah refraction it
breaks it down basically yeah it'll be at a different frequency yeah so did nasa put those
there just to prove they went to the moon is that like why no they put it there to to measure the
distance oh so they know the speed of light well so the amount of time it takes for it to come
back is the distance but
