Why is that relevant?

Cavendish was using lasers in 1797?

Anyway, none of the above is relevant to the Apollo 11 mission. Whether 
or not the gravitational law had a supportable theoretical derivation, 
it had still stood the test of time, and there was no reasonable fear 
that it would happen to be invalidated by Apollo 11.
