What black hole????

Such as the one at the centre of our galaxy, known as Sgr A*. Orbital parameters prove there is a 4m solar mass object there. Gravitational redshift backs up that proof. Perhaps you can tell us what this massive object is? Some sort of electric woo, is it? Lol.

It seems you need to study definitions.

So it goes.

Give it up, losers - you are in the presence of the world's leading authority not just on specific fields of science, but what science actually IS! Bow down to his self-actualized greatness.... before he whines to the mods to close this thread, too...

Is that on par with a cosmological model? A scientific model? Really?

I am not at all surprised that the obvious contradictory positions you routinely take were not obvious to you in your post.

You have already mapped them, you just pretend it’s dark matter, even if gravity does not form Fillaments, electromagnetism does....

Wrong. If these filaments were currents, they would be obvious in synchrotron radiation. It isn't seen. However, modelling of the cosmic web can only reproduce the observed structure using DM!

Agreed. We know nature is God's work. Physics is His design.
Now, and here, yes, it is part of it, as is the spiritual and many other things also are! How would physics apply to the garden of Eden or heaven or the coming Millennium though?

There is danger in taking one part of an equation and making it the whole equation!

Have you any way of confirming the supposed mass of...whatever it is...without knowing the distance?

Orbital mechanics and gravitational red shift. The orbits of the stars around it indicate that it's a relatively small and extremely dense massive object, and the light coming from its vicinity is red-shifted, indicating a very strong gravitational field, and it is a powerful emitter of radio waves; all characteristics of black holes.

The distance is ~ 8000 kpc. And it is irrelevant to measuring its mass, for the hard of thinking. As FB points out, we only need the orbital parameters of the stars around it. And Kepler's third law. Piece of cake.

M(bh) = (4 x pi^2 x a^3)/(G x P^2)

Where;
a = semi-major axis
G = gravitational constant
P = the orbital period

Do the maths. Comes out as ~ 4m solar masses. Gravitational redshift proves that it is a massive object.

You can't apply physics to things that are made up. Might as well apply it to Jack's beanstalk.

Yep. When people don't have God, then they need some other 'god', some substitute, and that's about a million different things, often money or glamour or the body, ideologies, etc., but sometimes a kind of science fantasy or ideology. Beware that making up a new physics and then being faithful to it instead of merely testing it to find out if it works can itself be elevating one's theory into a special level of adoration.
