The science of gravity spells.
narphoenix:
Well. That's actually pretty simple. Magically, Harry thinks it should work that way, so it does.
Physically is a bit more complicated. But, not impossible under wave-particle duality. If you assume that Harry used his magic to, on a subatomic level, move the gravitons (the particle expression of the gravitational force) from those areas (probably not all of them, but most of them at least) and concentrated them, boom. Flat vamps.
Adak:
If you want to see some more crazy numbers figure the amount of Ice it would take to Float that building section in CD, then see how much power it would take to make that much ice. The numbers become crazy if you assume free floating ice.

Gravitons (if they exist...) are fermions bosons, they have energy. They carry the energy when gravity does work, that is when gravity accelerates something. The objets in the big circle weren't accelerated, so there was no transfer of energy, so there was no graviton to move in the first place.

There was absolutely acceleration. Things don't just fall into nearly two dimensions from three. There had to be a force to make it happen. Ergo, there was an acceleration.

There was no acceleration at the moment Harry used the spell, the cars and so on where immobile, so there was no stream of gravitons.
