I'm not interested in the hot mantle geniuses, hence the "in theory" part

Eugene is right...and you can calculate how long it would take to theoretically reach the core and at what speed.
t = (2x/g)^0.5.....x = 6400km...g = 9.8m/sec^2
t = 1140 sec = ~19 minutes
v = gt = 1140 * 9.8 = 11.2km/sec = ~40,000kph
Neglecting air resistance, you would oscillate back and forth like this forever, with each complete oscillation taking about 19*4 = 76 minutes and you would always reach maximum velocity at the very middle.
With some kind of damping of this energy (by air resistance, for example), you would still oscillate for quite a while until you eventually deplete all kinetic/potential energy and come to rest at the very middle of the core.

I think you would almost come out the other side, less your wind resistance. If it was a vacuum you would have enough velocity from falling towards the center to move you the same distance away from the center for the second half of the trip. You would hit zero velocity at the opposite side then fall back in. Kinda like if you throw something up in the air, it comes back down at the same rate it went up. Except for wind resistance. So if your air-conditioned hole wasn't a vacuum, you would get most of the way to the other side, then fall into a decaying oscillation until you reached the center. But what about the rotation of the earth while this is going on? I think you would grind against the sides of your hole after you passed the center of the earth, and never get a chance to get far from the center. You would stop on the sides of your hole.

Assuming that you are pressure-proof, heat-proof etc etc you will oscillate between two openings of the hole.
Note that when you jump in you accelrate. At the centre you would have attained maximum Velocity. Because of momentum, you do not stop there, but move to the other end; but with a negative acceleration. Your velocity decreases to zero at the other end. If you dont hold on to something there gravity takes over and you are pulled back. The entire process gets repeated.

Any object dropped drown a hole would oscillate 'up' & 'down' in an exponentially decreasing simple harmonic motion manner. The gravity at the core of the Earth is zero as it is in equilibrium (equal forces acting in every direction). Eventually you'd be suspended in the very centre in a zero gravity environment.
Assuming of course you hadn't hit the side of the hole in the meantime, if so you're a very long streak of red mulch of a pioneer.

once you leap down the hollow, you will flow in simple terms approximately all a thank you to the different area of the earth, yet then you definately will fall decrease back in the direction of the middle and save going like that till at last you're suspended on the very center of the earth. it is via fact the middle of the earth is the place it is gravity is the main effective, so as quickly as you grow to be suspended interior the middle it is going to likely be just about impossible to get decrease back out.

you would start barreling down accelerating at a decelerating rate as the mass and gravity accumulates above you.
You would roar on past the center like a bungee jumper and eventually come to a stop right in the center of the earth,and merrily sit there til some one hauled you out.

That is so funny. I have thought about this very same thing. I think you would be able to jump down and almost make it to the other side and then yeeehaaaa back to the start and so on and on until you come to a stop in the middle.
It would be the best ride of your life.

Eugene has given you a good answer and if you take air friction into account, your oscillation ampltude will progressively reduce and finally you will come to rest at the centre of the earth.
Why can't people read your specific request to ignore the molten core part?

Okay.. assuming you wouldn't die from the extreme heat....
If you jumped in the hole, you would be in there forever ..oscillating back and forth.
Gravity would accelerate you down until you reached middle. The acceleration would be enough so that you would continue in the other direction, but now gravity would slow you down and eventually pull you back up. Forever!

Did no one read the "details."??
I think your question is FUNNY !!
My answer: you would come out the other side.
Depending upon which end you entered you'd wind up going twd some other galaxy, or, if out the ozone hole you'd wind up being sucked in by a big Black Hole.
Have fun! Tell the Startrek Crew I said "Hi!"
