OMG, that was one hell of a recoil to kick that much mass away at 2650km/s! Just... WOW!
My shoulder's hurting just thinking about it.
I was going to post the same thing. Anyone want to do the relatively easy math? How much energy is required to accelerate the mass of 100,000,000 of our suns, to 2650 kilometers per second? It boggles the mind..
