The science of gravity spells.

In Changes, Harry specifically mentions everyone floating up outside the target circle. Not as much as the things moving down in the inner circle, but then, Harry is drawing on fewer gravitons per unit area then he is concentrating them in the same.
Ms Duck:
sorry Knnn but it can't be affecting gravity, realy. what I think his spell does is borrow weight (the force of gravity) on objects in an area and concentrate it.
why can't it be what you suggest?
well, he's still there. :D
Gravity is a field.. you 'cancel' it somehow and it 'cancels' for everything.. including the several kilometers of air above the point. Which would have exploded outwards, then gotten drawn back in by your 'mini black hole'.. Im too tired to do the math, but as a WAGstimate I'd put the resulting force well into the atomic bomb category. (the initial explosion would have been more than 1 metric ton per square cm of area changed)(the secondary implosion would have been much, much worse)
Frankly, the whole city should have been redecorated..
I'd estimate it more like conservation of energy, he 'borrows' force from the objects around then concentrates it; what the vampire got hit with was the weight of several cars; not several cars, and several trillion tons of air.
;D

Where are you getting the 1Mg/cm^2 figure from? Air pressure on earth is about 1Kg/cm^2.
narphoenix:
M and K are close on the keyboard, I think.

Someone should write a book on the Physics of the Dresden Files
