Any mass in the Universe exerts a gravitational attraction. This applies to black holes, as well as other objects such as galaxies, stars, planets, etc. This gravitational attraction never stops, no matter how far you go away. However, if you go very far away, the gravitational attraction gets insignificant for most practical purposes.

There is no definite boundary for matter not being pulled toward a black hole. At large distances the effects of a black hole's gravity are not different from that of a different object of the same mass. How far out a black hole's gravity is dominant depends on that black hole's mass and its proximity to other massive objects.
It doesn't work like that. A black hole doesn't expand, unless its mass increases, i.e., when additional matter falls into it. And there is no place where its gravitational pull stops - the gravitational pull goes all the way to infinity (just as in the case of any other mass).
It is space that is expanding. The amount of matter doesn't necessarily increase. This means that the average density of the Universe is decreasing.It is space that is expanding.

NoAnswer:Present thinking is that the Big Bang created space, time and energy/matter. As a consequence at the expanding edge of the Universe there is a region of no space or time.
The largest known organization of matter is the universe, which contains galaxies, stars, planets, and other celestial bodies. The universe is constantly expanding and contains an immense amount of matter and energy.

That's because the Universe really is expanding. It started as a "big bang", where all the matter and energy in the Universe was concentrated in a tiny space, smaller than an atom - at a tremendous temperature and pressure. From there it started expanding, and continues expanding to this day.That's because the Universe really is expanding.

The ergosphere is an oblate spheroid region outside of the event horizon, where objects cannot remain stationary. While objects and radiation can escape normally from the ergosphere, there is still gravitational frame dragging of matter which is orbiting a black hole. Note: Think of the black hole's ergosphere area being like the Earth's graviational influence area of Low Earth Orbit.
I have a better question... You said you stopped talking to this guy because you couldn't trust him. What makes you think you can trust him now? Or does trust no longer matter to you?
Gas is one of the states of matter. Matter has weight and takes up space. When rocket propellants are burned or oxidized, they give off expanding gases. Since gas is matter the expanding gases exert force.
What is the nature of dark matter and dark energy? Are there other forms of life beyond Earth? How do black holes behave at the center of galaxies? What is the ultimate fate of the universe - will it continue expanding indefinitely or eventually collapse?
Scientists currently do not know what is inside the universe beyond what we can observe. The universe is thought to be mostly composed of dark matter and dark energy, but the exact nature of these components remains a mystery. The universe is continuously expanding, and its interior beyond what we can see is still a subject of speculation and research.
No such cosmological model exists. What you relate e is one description of Big Bang Cosmology (BBC), but that description is WRONG. BBC does NOT postulate that matter is expanding from a small, dense blob into empty space; rather, it describes a Universe in which SPACE ITSELF is growing at a (more or less) steady rate. Matter density is not decreasing in the way that ink density decreases as it expands into a large container of liquid; rather, the density of matter is decreasing because space is expanding as the amount of matter remains the same. Also, space is not expanding into anything, like an exploded material expands into the space around it. Space is just expanding, period. It is difficult to visualize, but the math works out just fine.
