   Physical constants, formulae and conclusions (source used: sci.space FAQ)

     1 megaton (MT) TNT = about 4.2e15 J
                        = about 50g of matter turned into energy
     G = 6.673e-11 Nm^2/kg^2
     c = 299792458 m/s (light speed in vacuum)
     parsec = 3.2616 light years
     AU = distance between Terra (Earth) and Sol (Sun)
     Luminocity of Sun = 3.827e26 W
     M = Total mass of orbiting and orbited bodies
     u = G*M (can be measured much more accurately than G or M)
     r = Radius of orbit (measured from center of mass of system)
     Vc = Velocity in circular orbit = sqrt(u / r)
     Vesc = Escape velocity = sqrt(2) * Vc = sqrt(2 * u / r)
     P = Orbital period (year-/monthlength) = 2*pi*r / Vc
     Black hole radius = 2*G*M/c^2 where M=mass of black hole
