• From GALEX: Speeding-Bullet Star Leaves Enormous Streak Across Sky - Marcia - 8/15/2007 10:41:23 PM
  • Speed due to planetary impacts? - Robert Clark - 8/17/2007 7:50:25 PM
    • no: conservation of momentum - relative masses. (n/t) - alcaray - 8/17/2007 11:12:01 PM
      • Yes, by conservation of momentum and relative speed. - Robert Clark - 8/21/2007 6:32:49 PM
        • No - nick hoffman - 9/9/2007 1:03:35 PM
          • Yes. - Robert Clark - 9/9/2007 3:07:49 PM

            • escape velocity has nothing to do with it, and again you ignore momentum - alcaray - 9/8/2007 5:49:53 PM
              • Escape velocity equals the velocity of impact, it's BECAUSE of momentum the star must be imparted with additional velocity. - Robert Clark - 9/8/2007 10:04:48 PM

                    • It is canceled by the energy of the red giant rushing towards the gas giant. - alcaray - 9/10/2007 9:00:07 PM

    • lambda nu equals cee - Hank - 8/22/2007 2:05:55 PM
      • re: lambda nu equals cee. Hank, I don't know what that means, but I also gave your argument some thought. :)_ (n/t) - Marcia - 9/8/2007 8:27:29 PM
        • lambda nu = c - Hank - 9/9/2007 12:36:29 AM
