It's speed? All this while Jim Scotti has been saying its the curvature going into the round
about the Sun, and now we learn its the speed? So hyperbolic comets are going faster?
Could you give us some examples? What is the ramp up that makes they become
hyperbolic? I'm sure the readership would like to know, as its news to THEM! They all
kind of float along out there, seemingly the same speed, and now we hear that those jazzy
hyperbolics are speed racer, all along!
Tisk, the secret life of comets. Who would have guessed!
