This video explains gravity in a way I haven't encountered before (regardless of how irritating the presenter may be). Nevertheless, I find it hard to believe that a squirrel falls from a tree to the ground due to gravitational time dilation between its head and its feet. The amount is so small I wouldn't think the velocity vector would be effected enough to cause any detectable motion, toward the ground or in any other direction. That said, is he on to something and simply misstating it? The shopworn analogy of a marble's path being deflected by a bowling ball on a trampoline makes sense to me for objects in motion. This video, however, makes me realize that that analogy seems to break down when dealing with restrained objects that are released (the marble would fall into the depression, but only because the trampoline is on Earth and subject to its gravity); why DOES the squirrel fall?
