My dad owns a landscaping/plowing business. He has these waterproof Carhartt bibs which are durable but don't breathe, are like diapers, and aren't totally waterproof (he has to hang them up on a clothesline for days to dry them out after a wet snowfall). I find good athletic, outdoor clothes to be flexible and comfy but are they durable enough? His clothes will have to withstand wet snow, dirt, diesel, oil, and road salt.
The well has a flat bottom for all objects except black holes. Of course that flat bottom is on the inside of whatever object is causing the gravity. Imagine you had a pipe going all the way through the Moon, that would insulate you from the rock, etc. An object at rest in the center of the Moon would float there, with no net gravitational force, and if you perturbed it, it would oscillate around the center, moving in the parabolic potential well. The potential well of a body of uniform density looks like this: far from the object, the depth of the well varies as -1/radius. Inside the object, the depth of the well varies as (radius^2) + constant, where the constant is chosen to make the potential continuous at the surface. So when radius 0, the derivative of the potential is also 0.
get outfits like the dudes wore on blades of glory.
