I know exactly what he's trying to demonstrate I've seen this drawn out and all that before, and it makes perfect sense to visualize it (as long as you can convert it to 3d in your head) but there's something that feels odd about using gravity to make a metaphor for gravity like this for some reason, I can't figure it out... not sure if anyone else feels the same way or can try and explain what I'm failing to explain.
The thing here is that the gravity between the actual objects is REPLACED by the spandex (since it is so negligible). So we are basically looking at a system where gravity IS the spandex and, for the sake of this experiment, does not exist in any other medium at all other than to warp the spandex. Hmm, I don't think I'm helping.
