A black hole is alleged to be the invisible object at the center of a distant star’s orbit. The mainstream theory is that a star is orbiting an invisible object that has lots of mass. It is the enormous amount of mass of the invisible object that compels the star to circle this unseen celestial object.
A black hole is said to come into being when an enormous star collapses on itself gravitationally towards the end of its useful life. Imagine a star that has several times the matter content of our Sun. It gradually squeezes all the hydrogen and helium gas until there is no more fuel. Gravitation gradually compresses these gases into solid, heavier matter such as silicon and iron. The star is no longer encapsulated in a gaseous foam, but now is entirely made of solid matter. If the star started out with several times the matter our Sun has, the gravitational attraction towards its center exceeds the capacity of matter to withstand such pressures. Matter is literally crushed out of existence…
“The matter that forms a black hole iscrushed out of existence. Just as the Cheshire Cat disappeared and left only its smile behind, a black hole represents matter that leaves only its gravity behind.”
What remains is a mathematical concept called mass. A black hole is entirely made of mass. This is what the equations tell the mathematicians and this is their conclusion regarding what is happening out there in the cosmos.
The black hole is described as a zero-dimensional object. However, the theorist always illustrates a three dimensional whirlwind projected onto a two-dimensional platform. Somehow, the theorists find it difficult to illustrate a zero-dimensional ‘entity’.
A rational individual challenges the notion that a concept such as mass serves as a physical mechanism to move distant stars around. Physics requires an elongated physical mediator to perform such action-at-a-distance tasks.
A rational individual also challenges that atoms can be crushed to the point that they lose length, width, and height. By what process, pray tell?
And nevertheless, it is highly questionable whether a zero-dimensional or non-dimensional ‘entity’ exists and whether such spirit can have any influence over existing matter such as a star. Again, by what physical mechanism?
Therefore, the task of a mathematical ‘physicis’ is not to provide equations and proof through experiments and observations. The onus is on a mathematical ‘physicist’ to present a rational mechanism for how a black hole achieves such miraculous movement of a distant star without an intervening medium.

“rational mechanism for how a black hole achieves such miraculous movement of a distant star without an intervening medium.”
The mechanism is gravity, just like any other mass.

You’ve been mixing up the singularity and the event horizon.
‘Gravity’ is not a mechanism. You’ll learn that when you get to high school. It is the mechanism of ‘gravity’ that we’re trying to explain.
And yes, the event horizon is an abstract CONCEPT that somehow morphs into a physical container that encapsulates a zero-dimensional non-entity known as a singularity. So far we have NOTHING! So far we have a NOTHING encapsulating another NOTHING: all zero D!
We don’t care to know what ‘happens’ inside a 0D non-entity the mathemagicians call ‘black hole’, ‘event’ horizon’, or ‘singularity’. We wanna know WHAT a black hole IS ! The mathemagicians haven’t got past that Q yet.

Really you need to do some more reading.
