DUST ON THE MOON LAYERS OF MILES DEEP

 The main concern back in the 1950s by astronomers is that that if ever man will attempt to go to the moon they may all sank because there will be several layers of  miles deep of cosmic dust awaiting them. The moon will have rivers of dust according to astronomer Thomas Gold. That was the common belief back then because common sense is, if the moon is 5 billion years old, you would expect billions of dust to gather on the moon's surface.

So before NASA sent Apollo 11 to the moon in 1969, they added a landing pad to strengthen its legs  and the ladder was intentionally 18 inches shorter because as we've said they thought they would landing on moon dust. The astronomers were puzzled why the amount of moon dust signifies thousands of years of accumulation only, and not the billions of years. You could say, thanks for lack of moon dust, they were able to do moon walk.
