Let me put it this way, its possible in theory.

Don't try and get TOOOO technical.  This isn't a real life possibility anyway.  BUT if all the factors were JUST right, what would the speed be?

About the glass it's all about the thermodynamics.  Solids have a crystalline structure that forms a proper lattice.  Glass does not crystallize, because the rate to viscosity rises.  This is why some physics guys say that glass is a liquid.  But a secondary transition still takes place causing rigidly bound molecules.

Solids have a crystalline structure, a proper lattice it is rigid.
Liquids have no proper order and are not rigid
Glass however does not have a proper lattice, but it's still rigid. 

I just wanted to see what the reasons were for your  belief.  I think Glass is actually a separate category!

Mod List.  Um WAY too many to fit on here.  But the engine can handle about 800HP

umm...this is not even possible in theory. the atmosphere is 100 miles high/deep. if u threw it hard enough to "come back around" it would just go into orbit.

not if you could keep the speed constant. Of course when you go to catch it, that's where the "don't catch it" part comes into play.

Yeah I guess the Gravitational force wouldn't be strong enough to keep the ball on earth, traveling at the speed it would need to.

It would be possible, with a constant speed.  Earth comes around to the same position every year and it travels in an ellipse around the sun.  Its basically the same thing.  In fact, it isn't too far from being proportional.

And glass is a fluid. not a liquid.  I think....  Huh

Glass is a liquid... In a materialistic state when melted.

If you want to waste some time.. here's your answer on the glass thing.  Grin

ok, i guess i didnt make it clear enough.. how are u gonna have a constant velocity if there's no constant force pushing it..he said THROW, not push....not gettin upset, just trying to let u guys see the light...if there was constant speed, there would be no need for an initial velocity of such magnitude that would be necessary to throw the ball into orbit.

Thats true, JBI.  I didnt think of it that way.  If you threw it in enough of an ellipse, it could be done....maybe...  However, I myself have not the finesse to calculate any velocities or the trigonometry of the HOLE affair. *get it?*
