We are discussing now, there is no concept of mass in singularity as m=E:c^2 , but I am objecting what is meant to be this mass m: it is ratio of Force and gravity constant m=G/g Then I think if the whirl is present on this ^^^ picture, the light must pass longer distance and it is slowed down at its speed, or just this trajectory must shrink to follow its constant speed ^^^

And this is the idea of modern fluid physics to jump in time space by our spaceship ^^^
