Can you explain this one? The Earth's cores are magnificently hot, I would assume even after removing them it would still remain extremely hot. Even if it wasn't the speed at which you travel would certainly burn you up.
Things I thought of when I was a kid but hadn't bothered seraching it up.

Surviving without a spacesuit in space:
Slow decompression will not kill you, 1atm to 0atm difference in pressure is also not that much of a change. The only problems, you would need to protect your respiratory system and continue breathing oxygen, probably by wearing an air tight mask with an oxygen tank. Covering the ears would be another precaution, but I would not know the effects of lack of pressure on them. Another major problem is hypoxia, I do not know if it happens under very slow decompression to 0atm pressure, but if it does happen it can be fatal fairly quickly. As for the temperature, you will burn if you are too close to a sun. As for cold pockets, there are practically no molecules in space, which means you likely still radiate and lose energy very slowly (kinda like a 97 degree sun), but I doubt it would be rapid, like being in ice cold water.

As for the core:
Assume there is a wide hole going through the Earth, as deep as the diameter of Earth. Neglecting death due to heat, pressure, or hitting a wall on the way, there are a few things to consider:
a) it is free-fall affected by pressure. The tube will be filled with gas, and assume that gas is equal to the pressure as you fall, as the pressure increases, the gas will increase in density, causing your terminal velocity to slow down, as air-resistance increases.
b) Assuming the air pressure never completely stops you (basically, the gas would have to denser than your body, think of it like the gas becoming similar to a liquid like water). You reach the core. Now, you will go past it, but your acceleration will likely reverse, slowing you down to a stop, then bringing you back toward the core again. Basically, this is similar to a point Darth brought up.
c) This may happen numerous times, as your are now a comparison to a weight attached to a spring, and I have no clue how far you would go past it, but this is assuming you make it this far.

No he said remove all the magma and everything else. I was talking about the surface of the earth. Which would be very, very cold at night.
The magma and the cores have extremely little effect with the heating up of the surface, the distance is so vast.

Of course not, it's just like looking with your eyes now and then closing them, if anything it would be worse as even less light passes through. (Although you will probably still see a slight glow as you can if you lightly close your eyes).
Thanks for the detailed response, I knew about the respiratory system but I did not realise that a 1atm difference wouldn't kill you, I just assumed from my biology lessons that you would burst as your body is trying to equalise.

Well actually as you go closer and closer to the core of the Earth, gravity decreases exponentially. At the crust is actually the greatest gravity, as you go towards the center or leave the crust gravity decreases. So if you were to jump you would accelerate but it would decrease fairly quickly and you wouldn't come anywhere near the other side. You'd slingshot back and forth until you reach the center and float. (excluding basic necessities).
And if you went into space without a suit, you could hold your breath but once you let go you'd die and eventually freeze but you wouldn't explode

Human life hasn't been dated until a few hundred thousand years ago. To the earth we're a blip. And certain civilizations didn't like advancing technology and halted research (like the dark ages), which is one of the reasons we don't know a lot about just a few thousand years ago.
As for time travel, if it were possible, we would know it worked because we would meet a time traveler. You can only go as far back was the first time machine (considering its a time machine and not a space/time machine)
what do soldiers do in their spare time?
If it hurts, taste bad, create agony, does that mean it's good for you?
What gives human's their skin color, what are their origins? (don't mean to be racist here)
Why do water taste so bad after eating pineapple? Why do Pineapple taste bad after I brush my teeth?

Pigment (called melanin, most common type in humans is eumelanin ) is produced by cells in your skin to protect your cells from the harmful UV-radiation present in sunlight. Thats why groups of people who live in areas with higher levels of sunlight (i.e. near the equator) have darker skin than those that live near the poles, simply because they need more protection.
UV-radiation can damage DNA and cause cancers, particularly melanomas. So its probably a good thing to protect ourselves from it...

Oh I see how it is! I say facts in the ShoutBox and you return with lies, PURE LIES!

depends on the size of it and your hand, but not really because its either already against your fingers or moves so little it wouldnt hurt as much as actually hitting someone
