Lets say i have two metal hemispheres made of iron and they are

Just depends on what the pressure is in that area.

The water levels being equal indicates that it is 1atm inside your little alcove there also. It would take a very low pressure environment to separate the spheres assuming there's a good seal on it. Air at 1atm is 14.7 psi relative to vacuum I believe. You would need the strength to overcome that over the whole surface of the sphere. At 0.5 atm air would weigh 7.35 psi, still pretty heavy.

It would be pretty much impossible to separate the hemispheres, if i recall correctly not even teams of horses linked up with ropes could pull them apart once a vacuum was established inside of there

It would be harder because air pressure is slightly higher down there, it has nothing to do with how much space there is.

How high are you right now?

>>8824582
Couldn't you just slide them apart?

And teams of horses? WTF?

As you can see in the picture, not even teams of horses linked by ropes could pull the hemispheres apart, the pressure of the atmosphere is really something, its amazing we aren't crushed by such pressure

>>8825573
Fucking kek'd

I wouldn't say amazing; were equalized by the same pressure on the inside

We were born into it; molded by it
