If gravity is not based on magentism then why is a blocked pound of steel pulled faster to the Earth then a blocked piece of wood?
I believe that there have been many experiments carried out similar to the one you describe. In every instance where the pound of wood and the pound of steel are placed in an evacuated chamber (a vacuum), they both fall to earth at exactly the same rate. In fact, if a ton
of steel and an ounce
of wood were dropped in such a chamber, they would both fall to earth at exactly the same rate (9.8 m/sec^2).
