So, I’ve got my shovel and I’ve packed extra sandwiches. I’m going to start digging this afternoon. My plan is to go straight through, directly through the Earth’s core. (OK, so I’m geographically off. Nevermind. This ain’t a geography question.) For safety reasons, I also plan on lining the hole with special tubing, so as to save myself from the harmful effects of heat and crushing pressures. Safety first, after all.
So I figure that the first half of the trip will involve me climbing down the hole. The second half I will be climbing up the hole. This leads me to believe that at some point near the middle, I’ll be climbing neither up nor down, but instead I’ll be weightless.
Is that true? Will the Sun and Moon have an appreciable effect on my fun yet inefficient weight loss plan? How about if I used my special disintigration gun to eliminate them?
