Middle of Earth: Atom or No Atom?

[binbots]

At the point where all gravity equals 0, (middle of the earth) is there a atom. Or does it lie between 2 atoms. Is this something that has not be measured because gravity is to small at this point. Or is just s pointless question?

hi binbots!

the point at which the net gravity is zero has to take account of the Moon …

it turns out to be a long way from the centre of the Earth (I forget the exact amount, but you can easily calculate it yourself ), and of course it moves around inside the Earth as the Moon moves

Net gravity is only a sum of all the gravity interaction together. There is no necessary center as no specific atom acts as center or medium. Treat it as if it were many indivual gravitational fields rather than one field.

I hadn't given the OP's question much thought before but upon just thinking about it it does raise some questions.

given the gravitational field would be changing in respect to time and location due to the balance between the two bodies and there rotational frequency. wouldn't this create a gravito-magnetic effect a bit larger than the just the Earth itself? and the moving field being asymmetric to the center line of the Earth cause a constant shift in the pressure and temperature of Earth at it's location? would this still be the case if the Earth moon was a binary system and not a satellite one?

My thoughts...

Gravity, pervasive as it is, is VERY weak.
That our moon's gravitational influence affects oceanic tides should not be further presumed that it affects much deeper into the core of our Earth with any substantial/noticeable influence.
Not sure though.
