I've been scratching me' head a little. For curiosity's sake i've been trying to calculate what "would" be the kinetic energy of a black hole moving across the galaxy at a certain velocity, but whenever I tried assigning any value to the eqation it spells disaster:(adsbygoogle = window.adsbygoogle || []).push({});

E_{kin}=(2D∏r^{3}|v|^{2})/3

Based on this equation there are 2 possible outcomes:

1) the radius of the black hole is zero, the most widely accepted belief in that case the black hole will allways no kinetic energy whatsoever regardless of its velocity (E_{kin}=0)

2) Some believe that the radius of the black hole is infinetely small, but yet not zero, in that case the black holes have infinite kinetic energy (E_{kin}=∞)

In either case it got me into a bewilderment. You propably noticed that I took the classic equation apart because I was unsatisfied with the black holes mass being the same while its components went into the extreme.

Is it futile to even aproach black hole phisics from this perspective or is there another way?
