A black hole is the *only* thing that can explain the motion of those stars. Just try to imagine a 4 million solar mass object in a body with a Schwarzschild radius of only seven million miles... about 7 times *smaller* than the radius of

Mercury's orbit!

There are no black holes anywhere, except around the heads of physicists permanently locked thus.

Just saying "no such thing because I say so" doesn't cut it. Especially >>>> when you consider what ELSE can explain 4 million solar masses crammed >>>> into 7 million miles diameter, and when looking there we can't see

Where is it? Have you been there? How is it so nicely measured? With imagination and thought experiments?

Are you really so stooopid that you are unaware of how we know about SGR >> A*? Hint: We can tell its mass from Kepler's Laws and the orbits of
several stars.

Just nothing.

What are those stars around SGR A* orbiting? Stars don't orbit "just
nothing".

Yes they do. Heard of binary stars?

That's rather misleading of you. Binary stars don't orbit "just
nothing", they orbit each other. Or technically their barycenter.

At least this is clear, good. You are not saying there has to be a black hole at the centre of a binary system, and that is a mercy.


Tell

us, what are those stars around SGR A* orbiting?

Around each other of course, just as a binary star system.
Their centres of mass, for the two halves of the stars, are doing just that. Behaving as a binary star.
I thought this was only too obvious, but equally obviously I was mistaken. I tend to overestimate the intelligence of the supposedly intelligent and that is a mistake.

The barycenter of
themselves and what?

What indeed, answer is nothing. NO black holes around, just as there are no black holes between binary systems.
The entire galaxy thus behaves as a binary system, endlessly rotaing around NOTHING.
Just gravity, an electrostatic force, perennial as charge, and kinetic motion, are at work to keep things going from infinity and eternity to infinity and eternity.
Now, this may be too much for your weak minds to grasp. It is only recently that you barbarians/bandits have grasped some idea of the concept of zero.
Infinity is the inverse of zero.



We know from Newtonian mechanics, should we choose

to use that, that the other part contributing to the barycenter has a
mass of some 4 million suns, and a maximum diameter of 7 million miles (otherwise stars would have crashed into it) yet it's invisible.

It is invisible because nothing is invisible.

So tell us, what is invisible and has 4 million solar masses but isn't a black hole?

NOTHING.
