ELI5: Hypotheticaly, if you made a hole straight through the earth and someone jumped through. What would happen to gravity?

Would the person free fall and then at the exact middle stop, essentially being stuck in the middle; would there be equal amounts of gravity working in all directions?

Assuming a perfectly spherical ~~cow~~ Earth with completely uniform density and an airless tunnel etc, etc.... 

>would there be equal amounts of gravity working in all directions?

Yes. Which is the same as saying they're weightless (at this point).

> then at the exact middle stop

No - they've already built up a ton of speed falling. As they rushed past the center, they'd gradually *de*celerate until they stopped at the surface of the other side and started the whole process over again.
