Just as an amateur I wonder what happens at a center of a planet gravity. The standard picture where space curves like a \/ due to gravity or the curve beeing the gravity puzzles me about what do happen at the \/ center to were all the "force" converge. Can it be possible it reflects up to a small distance as anti-gravity? instead of just be confined to a point, just move on? as long it move pass that point it would be pushing not pulling, just because of beeing past the center of gravity. Is there anyone this also makes sense?

Electrons move at about the speed of light around a nucleus. Because their mass is almost zero, it would seem if we could move at the same speed as them, we would go right through them.

a steel rctangular beam of 50mm x 25mm and the maximum allowable tensile stress is 165n/mm2is rigidily attached to a piece of timber 500mm x 80mm in section and 2m long.
if the modulas of elasticity for the timber is 9.6kn/mm2 and the max allowable stress is 8.5 n/mm2 determine the max safe load that the composite member could carry

I think looking at how gigantic the earth is and looking around into space and knowing it's neverending, dark, and cold - that would scare me. Other than that I think it would be beautiful.
