Formula related to astronomy?

Answer 1

m-M = 5logd-5

Answer 2

{F|F>1x10^-10, F=MA}
{F|F<1x10^-10, F=MA^2/(Ao)}

If you need cutting edge physics equations that the majority of humanity will say "Huh?" at, the MOND equations are the way to go.These equations create the illusion of dark matter by modifying the laws of newtonian physics at very small accelerations. The (AO) term is actually supposed to be the letter A with a funny little o subscript written underneath it. No one is sure why this happens, but it does explain dark energy perfectly.

Answer 3

P^2 = A^3
F=GMm/R^2
Distance (in parsecs) = 1 / Parallax (in arc seconds)
Resolution of a telescope in arc seconds = 4.56/D (where D is aperture in inches.)
