If we dug a hole to the center of the earth...

[Pony Soldier]

We would die.

I think there would be crushing gravity even if you werent actually under any rocks.

Actually, it would be the opposite. Well, pressure would be high, true, you would have to deal with 6,000+ km extra and condensed air column. But the gravity near the center depends on the distance from it roughly linearly, and at the very center it is 0. You could make very long jumps there, and it would feel really weird!

Would be a great spot for a BBQ.

A HUMAN BBQ!

[Evil Midnight Bomber]

I don't know if that'S the truth but I am sure those actions would destroy our planet. GG greed, you have finally done it.

That's how they explain it in Man of Steel anyway...too much reckless mining of the core.

[Dezerte]

We'd find trolls.

[Lady Dragonheart]

The pressure would collapse it with magma...

[Knolan]

Dude, let deathwing sleep in peace.

But jokes asside:

We would just find a lot of different ores and then magma, I doubt anything would happen to the planet.

[dextersmith]

The hole would be 2 feet deep because the world is flat.

[Glnger]

Didn't we already do this in the documentary film called The Core?

[jackofwind]

We already know how to get there.

Edit: see poster above

[lonely zergling]

We would find the Morlocks.

Well, magma chambers of volcanoes are roughly 10-20 km deep. If we were to drill a hole over 6,000 km in depth, all the way to the core, then I would expect an extinction event due to insane volcanic eruption.

[Gaaz]

Aside of pressure and heat, drilling that deep is giong to be impossible for several other reasons:
1st - there is nothing to drill. At temperatures of 6000C iron planet core behaves like liquid (though considered solid state because of pressure). It would be gaseous actually (2900C is needed for that at sea level), but 3.6m atmospheres of pressure keep it from that.
2nd - The core and surrounding magma actually rotates. That is what keeps Earth's magnetic field on (that and cooling). So it is like passing through molten iron that tries to evaporate, is solid dence despite that and actually tries to twist your drill equipment around the axis of it's rotation

I am not a physicist, but I don't think it would happen in those extreme conditions, it is not a simple scenario like making a hole in a air filled ball. The "walls" would be liquid, dispersing the pressure a little, the air pressure itself would be far greater, heck, at that scenario even gravity would be lacking.

Why don't we just nuke she shit out of Mars or Venus and use satelites to examine what gets ejected out

The thing is, currently, to my understanding, the only thing that counters the extreme magma pressure under the surface is the thick crust. When this crust is pierced by a small narrow path even just by 10 km, we have a regularly erupting volcano; but under the "bottom" of this volcano, there is equilibrium between the magma and the crust pushing from the top, and magma pushing back from the bottom.

Wherever we start drilling, there is also an equilibrium. If we drill all the way to the liquified magma, the equilibrium will be broken, and the magma will erupt through the whole with incredible speed. The further to the core we drill, the more this equilibrium will be violated. I'd imagine that if we drill deep enough, then magma pouring out through the whole would gradually increase the size of this whole, and eventually we would have a "mega-volcano" leaking magma all over the planet's surface, until equilibrium is achieved once more - which might be late enough for the life to have been wiped out completely.

Of course, I might be wrong; I can't say I am an expert on the conditions under Earth's surface.

Rofl, I was gonna say this. That super submarine was pretty fucking sweet, I want to go down there and get me a diamond the size of Texas.

[IIamaKing]

I enjoy thinking that Jules Verne was close to the mark.

[Mitters]

You'll find china

It's like saying that we didn't know what a baby development was like until rcently, when '' EVERYBODY " in the past knew than humans' babies = every other species babies and because of cannibalism and war, cutting those bellies...
