It seems common sense that as you go deeper into the Earth (eg with your feet towards the center) you will feel increasing pressure from the matter on top of you, that's what happens in deep sea. It may also seem common sense that the very centre of the Earth must be an ingravity place, because you have just the same amount of matter in any direction surrounding you. Is this correct? But if so, even being in zero gravity does anyway still mean that you have huge pressure from every direction? Shouldn't gravity from the surrounding matter "pull you outward in every direction" instead of pulling you down as it does in the surface? Is there a relationship between gravity and pressure in this context? Thanks!
