      even using an ideal drive (exhaust velocity = c), the mass ratio you'd need to have a deltavee of 0.995 c would be 2.12e4. That is, you'd need 21,200 times more fuel than payload. The mometum of a photon is given by . p = E/c, where E is the energy of the photon, and so the thrust delivered by a stream of them is. dp/dt = dE/dt/c. or. F = P/c
