[QUOTE="Dannyalcatraz, post: 7080335, member: 19675"] Actually, no I'm not- as I explicitly pointed out multiple times, neither the occupant nor the sphere can be the source of the decelleration force. The same problem exists regardless of whether we treat the ORS & occupant are treated as a single body or two. In the single body problem, the question is simple: how do you suffer deceleration damage from the ground when the ORS state's the occupant can't be damaged by forces originating outside the ORS. By the terms of the spell, the occupant can't be. In the double body problem, the ORS is stopped by the ground, then milliseconds later, the occupant smacks into the ORS's inner surface. We know from Newton's 3rd, that the falling occupant can only decelerate if an equal and opposite force is applied to his momentum. So we have to ID the source of the force. 1) the occupant can't be the source- that would mean he is not only supplying his kinetic energy, but somehow supplying energy to stop himself. How can he do this- doubling his energy- without thrusters? 2) the sphere can't be the source- for all intents & purposes, it is massless, and cannot deliver enough energy to decelerate the occupant. If you hit a relatively massless thing with something heavy, the massless thing will deflect off at a high velocity and the more massive object willhardly be slowed at all. The double body problem is essentially the falling boulder illustration twice- first, the great mass of the ground halts the ORS without noticably slowing, then the same sphere is struck by something else with a great mass compared to itself. If it could, it would simply start moving again, the occupant hardly slowing. But it can't move because it is resting on the earth, you'll say. This is true, which gets us to: 3) the ground is the source of the deceleration force. It's the only thing that [I]can[/I] supply it. But this outside deceleration force, originating as it does from outside the ORS, can't damage the occupant...the same answer as in the single body problem. And See above. The deceleration energy can't "already be inside the sphere". There is nothing there to provide it. The ORS by itself lacks the mass to resist the occupant's momentum in any meaningful way. [/QUOTE]
