That's awesome.

Things like this always make me realize how insignificant our knowledge as a species really is. Look at the "facts" they teach kids in school or "facts" that are published about events, our planet, our history, our solar system. Its all best guess. We have no idea whats in the deepest parts of our ocean. We have no idea how deep it even is.

We have no idea whats at the center of our world. They make best guesses that our planet has molten iron in the center... but they dont know other than guessing by how fast earthquakes rattle through it. We have no idea whats outside of our planet.

Our species is still so young and foolish. We pass off guesses and estimates as facts and teach the young things are something they arent. Poor foolish humans.

Solid Iron, actually, surrounded by molten iron and nickel. The rotation of it and the slower rotation of the molten stuff is what creates our planet's magnetic field -- which without we'd be baked to a crisp via solar wind.

[Ralaya]

Seriously.  Didn't you watch The Core?

Ahhh you poor fool. Now go and read how they "know" that. They take best guesses due to the amount of time it takes seismic vibrations to get through the middle of the earth. They then figure out what would take that long to get through and poof there is your "fact". Now one could make the completely logical argument that anything could sit between here and there including elements we currently arent aware of since we have yet to make it even half way through the continental crust and those elements would have their own seismic vibration time... but we just assume we know everything thats down there...
fact.

They arent sure what creates the electromagnetic field. They arent sure what keeps our atmosphere in place. The assume its the molten metal spinning but its yet another guess. There is also a prevalent opinion that gravity keeps the atmosphere in place and gravity causes the EMF... but no one can prove a damn thing because all our facts are based on guesses.

The Core was a fucking great movie... but like 2012... just cause Hollywood makes a movie about it, it doesnt mean its anything other than 100% fiction.

Gravity can do a lot of things -- sadly we don't know where the particle that controls gravity is. (we have observed all the others, electromagnetism, weak and strong nuclear forces)

So yeah, there's ignorance in that regard.

You told me those were documentaries!

My understanding is that gravity isn't necessarily controlled by a graviton but potentially an inherent aspect of the curvature of space/time by matter.

[Grolish]

They have their pressure numbers wrong.

Water pressure is approximately 44 psi per 100 ft of depth.  (pressure is about 5,720 psi at 13,000 ft)

The search isn't for a graviton, but for the particle that causes mass itself, which would then curve spacetime.

Me fail English? Thats umpossible!

[Inzema]

In my mind, it is entirely possible that the center of the earth is hollow.  Because why can't it?  Who's to say seismic waves can't travel through air?

[Pincus]

Speed, really. And reflection due to density differences and rate of propagation in different media.
