Ever heard the saying that if a feather and a bowling ball were dropped in a vacuum, they would hit the ground at the same time?… Neither have we, but we have heard many similar sayings and claims by okes. Usually around braais as useless facts.
Well, we have wondered whether that is true. Have a look here as Brian Cox drops a few feathers and a bowling ball at the same time, in the world’s largest vacuum chamber.
So, apparently Isaac Newton’s theory of gravity, is no longer a theory. It is clearly visible that it is only the drag / friction of the air that holds the feather back.
This experiment was done in NASA’s Space Simulation Vacuum Chamber, just outside of Cleveland, Ohio.
Man this is awesome!!!
