It makes you think if this isn't have the same effect there must be some huge hollow spaces bellow the earths surface, somethings going to give sometime

Is your brain hurting after all that thinking? Does it feel like it's going to implode and leave a great void within your skull?
Well don't worry Jay, the deepest mine in the world is TauTona in Carletonville, South Africa at 3.9 kilometers.
The average thickness of the Earths crust is 100 kilometers so, we are hardly scratching the surface, we aren't yet producing a planet resembling a Swiss cheese.
