Message: <blockquote data-quote="Xetheral" data-source="post: 7993780" data-attributes="member: 6802765">My entire post was intended to be satirical, but if we're going to treat it seriously....[USER=6801328]@Elfcrusher[/USER] The problem is that hitting the Sun requires at least 30 km/s, and the caster doesn't have enough time to even reach that high before the expanding Sun engulfs the Earth anyway. Reaching a change in velocity even greater than 30 km/s would take even longer.[USER=6801845]@Oofta[/USER] The 30 km/s change in velocity necessary to hit the sun is measured relative to the sun. I apologize for not being specific.Even though we're treating the Earth as "weightless" on the grounds that it is in freefall around the Sun, it still has 5.97*10^24 kg of mass, and that inertia will resist the acceleration created by the force from the mage hand. We know that the mage hand can't generate more than about 10 lbs of force, or else it would be able to support objects weighing more than that. (We can't calculate the exact maximum amount of force the mage hand can generate because the spell doesn't contain enough detail about its acceleration profile when it moves objects.) So from a physics standpoint, you definitely can't use mage hand to accelerate the Earth at 30 ft/round per round.Even ignoring force and inertial mass, the spell description suggests that 30 ft/round is the mage hand's maximum velocity (relative to the Earth), not its maximum acceleration. So going only by the spell text, mage hand is capable of changing the Earth's velocity by no more than 30 ft/round total. If so, the mage hand will never be able to push the Earth into the Sun, no matter how long you push, because you'll never get the net change in velocity higher than 30 ft/round. At 5 ft/s, that's a far cry from the required 30 km/s.</blockquote>
