The brick actually does hang weightless (in freefall) depending on your point of reference.Gotta hand it to you Brits. You have the best humour. No discussion.
Sometimes a random sentence from Hitchhikers’ Guide pops up in my head and I laugh out loud.
“The Vogon spaceships hung in the sky much in the same way bricks don’t” is a sentence of such quality it HAS to end up in some “best literature of the twentieth century canon”
I digress. Right. Salsa research it is.
All objects appear to fall at the same rate because they are not accelerating (inertial frame of reference). They're just following a straight line through the curvature of spacetime until they encounter an object that stops them.
The Earth in this case, moving through spacetime at 9.8 m/s², accelerates into them. It's at this point during the process of rapidly accelerating from "weightless" (freefall) to "weighted" (accelerating) that the real damage is done... (I know, overly simplistic explaination...)
That's why a bowling ball and a marble both hit the ground at the same time when dropped...
