And what of the Earth?

If all things are manufactured from the earth through mining, oil drilling and the like and are brought to the surface of the the planet, what keeps us from caving in? I'm just imagining that if the earth was cut into two parts, would we see a swiss cheese effect. I think so and if we keep on creating holes what will it mean for the future. All the skyscrapers in the world as with other monstrosities are not featherweights. Gravity has a breaking point. Who can guess a logical explaination to this?

    The removal of coal, oil, and even water from underground can leave voids and/or structural weakness, and sometimes after a lot of extraction, the earth's surface settles. This is called SUBSIDENCE, and it can account for declines in surface elevation of 1 foot or more. Subsidence is most dramatic above underground coal or mineral mines. There's been a lot of it in areas like northeastern Pennsylvania. Obviously, it can cause a lot of property damage if your house is on land that undergoes subsidence.

    If the Earth were scaled down to the size of a billiard ball it would be smoother than any commercial billiard ball.

    If Everest and the Marianas Trench cannot be noticed on this scale model, nothing built by man could be noticed either.
