To get back to the topic! Because this is NQS I can reference a TV programme without scorn from the throng--- OK?

I was watching my current favourite TV show last night ( Big Bang Theory) when the group of scientists set up an elaborate system of lasers and measures that used the instruments left behind on the moon to measure how long the message took to bounce back.... AND co-incidentally proving that the equipment left there was in fact still there to be bounced off.

Now I know this show is fictional (mostly!) but I am interested as a non-scientific person to know if this experiment could be performed ---and if so why is there still doubt about the journey, and if not--- what an inventive script writer this show has!

It was a very nice episode, one of the funniest!
