One day you will meet your match and have to come back to edit this post.
Oh no. Iâd be more than happy to sit down nude with them and discuss their god thingy. No problem!
Wouldnât you just fall back through on the other side?
Would you have enough, for lack of a what might the correct physics term, gravitational momentum, to make it through to the other side?
Would that slow over time?
I love weed sitesâŚweâre all high while weâre wondering these thingsâŚAnd the best part is thereâs likely someone smart enough here to answer these questions with credibilityâŚâŚand then thereâs @Foreigner 
You just need a really long rope silly.
In a lossless system, you would reach the other side. But presumably there still exists drag from air friction which would dissipate the energy, so you wouldnât make it there. That is, assuming you somehow wouldnât combust when traveling through the core.
Not to mention the pressure of like 3 million atmospheres.
Pretty sure if the sides are smooth enough it wouldnât be hard to achieve a vacuumâŚ
Yes, and it needs to be attached to your destination side. Youâll fall for the first half (or more) of your journey. Youâll have to climb the rest of the way.
Bring some dynamite and create a molten geyser to propel you to your destination.
You wouldnât fall through, would you?
At the center of the earth is where the Gravity from both sides âmeet/stopââ so youâd only get to that pointâthen stop?
Theoretically, wouldnât you be be stuck there (without a hoist or very long ladder anyway), because BOTH SIDES have gravity pulling toward the center, the point at which you stopped??
I agree somewhat, but I think youâd bounce back and forth like a piston until you would finally come to a dreadful stop in the center. Hawking wouldâve known how thisâd work.
