re: If you could travel to he center of the Earth, you'd be weightless.

Abbar Yamad, a well known Indian physicist, opined that there was an exact point at which a person near the center of the earth would be mostly weightless (The Yamad Theorem). However, that point would change depending on where the earth was within its rotation.

This is true because the earth is not a perfect sphere.

you would only be weight for the time your exact center of gravity was at the exact center of the Earth.
No, this is wrong. The earth would not be net zero gravity when you are weightless. The earth would have to exert a gravitational vector to cancel out that of the rest of the universe - mostly the sun.

Never said the center of the earth was a black hole. I wasn't aware that speculating on hypothetical situations was prohibited on the O-T.
Sorry. If yoiu weren’t implying that the center of the earth was a black hole than your sentence about black holes was a complete non sequitur.

From Newton's law of universal gravitation the mass of the earth is zero at its center. No mass, no gravity.
Maybe I'm misunderstanding but I do not believe this to be the case. Even if you are weightless at the dead center of the earth you would still have mass. If there was pebble floating next to you it would eventually stick to you because you create a small gravitational field.
Kinda like if you're in the middle of interstellar space with no external gravity acting on you, you would still have mass and exert a gravitational force on anything near you.

Assuming you won't burn up.
That would still render you weightless in a different way.

Also what's kinda cool is if there was a tunnel that went all the way through the entire earth and you jumped in you would fall all the way through, past the center, and then slow down and fall back the other way... over and over until you eventually stopped in the middle.

You do know that the composition of the earth is just a theory.. Nobody really knows what’s down there.

Because you would be smoke.

I’ve been there. Not true.
