Quote:Okay, poor analogy. So let's say that you're floating around in space, weightless and all. Then someone lays an anvil infront of you and one behind you. Now imagine that each anvil is equal to the mass of half the earth. That would give them a lot of gravitational force, right? But you're in the center, so you wouldn't feel anything, but what about the 2 anvils themselves? They would still be attracted to each other, so now they are both pushing on you because they are trying to move closer together due to their gravitational attraction towards each other. No pressure, eh? ^_^Radical Raccoon Wrote:Agamemnus Wrote:Just because everything is moving towards the center doesn't mean there is more pressure at the center than anywhere else
Yes it does. Tons and tons of matter is constantly moving towards the center. It doesn't have to move fast to create more pressure: it's the weight and not the speed. Lay down and have someone softly lay an anvil on your chest. Are you not going to feel its pressure pushing down on you?
Weight is determined by mass multiplied by force of gravity, not mass alone. If you lay an anvil on me in space, I won't feel any pressure, because there is almost no gravity.
