First, derive a set of geodesic equations a massed particle traveling
at high speed near the sun. Then, gradually reducing the mass to zero
and increasing the speed to c, do you see a discontinuity at mass = 0
and speed = c?

As you know, the geodesic equations are independent of mass. What
does that tell you when the model predicts a 1x deflection traveling
at speed just a hair below c and suddenly jumps to 2x deflection at
speed = c?

F*cked up.
