Because *you* did.  I then set and announced Followup-To so that the 
crosspost would _not_ be continued by anyone after me.

But despite what I told you, you did it *again*.  Are you stupid?

No.  To begin with, you said that S14 would only collide with "it" if "it" 
were “any *larger*” (emphasis mine).

Do you know the difference between a greater-than and a greater-than-or-
equals operation?

I can.  Evidently you cannot.

Nonsense.  Even if we consider that there are no stable orbits below 1.5 
Schwarzschild radii (the radius of the photon sphere), that is still less 
than 0.12 AU for a black hole of this mass.  Nowhere near 45 AU.

You still have no clue what you are talking about, despite my patient 
explanations of where you went wrong.

Are you stupid?
