Ok, zero g in the center of the earth, 1 g at the surface of the earth, and gets less and less the further you go out. What is the max g point?
"Ok, zero g in the center of the earth, 1 g at the surface of the earth, and gets less and less the further you go out. What is the max g point?"
The maximum g point would be at the earth's surface, or 1 g. As one went beneath the surface, the pull would decrease until it reached zero g at the center. If the earth were hollow (which seems unlikely), it would reach zero g as soon as one reached the hollow cavity.
"Stevenson would start the process by finding a suitable fissure in the Earth’s crust, setting off a multi-megaton underground nuclear explosion to widen the fissure to a sizable crack, and then dumping in an instrumented blob of liquid iron (melting point 1535 C) with a mass of about 108 kilograms, the amount of iron in a sphere about 30 meters in diameter."
Something's wrong here -- a solid iron sphere about 30 meters in diameter would weigh more by a factor of about a million . . .
