Why the Galaxy Core (Sgr A*) is not a Super Massive Black Hole.

Six reasons why the Galaxy Core (Sgr A*) is not a Super Massive Black Hole.

1. Bright in the x-ray. 
Logic suggests a Super Massive Black Hole in a super matter rich environment, like the Galaxy Centre, should be super bright in the x-ray. It is totally invisible.
2. Large accretion disc.
It must get super big somehow - that can only be accretion. There is a disc but matter seems to be spiralling away and not inward which defies gravity, so no accretion and not a black hole.
3. Flare with variations in accretion.
It should flare as stars are accreted. This object appears uniformly obscure and mysterious.
4. Compact.
All black holes are fully compact that is an important part of their physical properties. This thing is semi-compact and so not a black hole.
5. Rotation speed.
The Central Object is calculated to be rotating very fast. Black holes are the product of collapse which boost rotation as the decrease in circumference generates an increase in speed. However, it’s girth has become far greater than the star it was made from which must hugely slow orbit. So cannot be rotating fast.
6. Mass.
The only entity we know that can become this massive are black holes. Which assumes we know about every object in the Universe - which we don’t.
