Yes and No - While the current measure for the mass of a black hole is based on an indirect measuring of the speed of the orbiting material, there is no direct measuring of the density of a black hole.
Density is a concept involving mass divided by volume. While one can abstract the mass of a black hole, measuring the volume is a little tricky. We know there is a boundary at the Schwarzschild radius (Schwarzschild horizon) and this is also called the event horizon. Bascially, anything that happens beyond that point is unknown to us. Supermassive black holes have properties which distinguish them from lower-mass classifications. First, the average density of a supermassive black hole (defined as the mass of the black hole divided by the volume within its Schwarzschild radius) can be less than the density of water in the case of some supermassive black holes. This is because the Schwarzschild radius is directly proportional to mass, while density is inversely proportional to the volume. Since the volume of a spherical object (such as the event horizon of a non-rotating black hole) is directly proportional to the cube of the radius, the density of a black hole is inversely proportional to the square of the mass, and thus higher mass black holes have lower average density.
To complicate things even more, space-time is highly distorted around a black hole, so even asking how big it is, adds further complexity to this answer. Nonetheless, black holes have a mass and size. However one can not know if the mass inside is accreted all at one point or more spread out and distibuted. It appears the inner dynamics of the black hole provide for a plasma like accretion disk, which that pretty much changes (or distorts) our traditional dimensional frame of reference. It could be that the black hole merely suspends acquire mass in a medium of energy state. Consequently this medium of energy may preclude its growth or shrinkage.
Black holes do not "suck in" large objects; black holes "suck in" only dust and plasma. This is because by the time a large object gets anywhere near the event horizon of a black hole, the tidal forces caused by the gravity of the black hole has already pulverized whatever mass the object had. The gravitational force of a black hole's singularity is almost impossible to comprehend. It may not be strong enough to tear apart the nuclear forces of an atom. but it is certainly powerful enough to rip any two atoms apart, no matter how tight the chemical bonds might be.
Gamma radiation emitted by black holes can originate from the accretion disk around the black hole or from high-energy processes within the black hole itself. This radiation can escape the gravitational pull of the black hole and travel through space, potentially affecting nearby objects or being detected by telescopes as a signature of black hole activity.
The stellar objects with the greatest density are neutron stars. These remnants of supernova explosions are composed primarily of densely packed neutrons, resulting in extraordinarily high densities, often exceeding that of an atomic nucleus. A sugar-cube-sized amount of neutron star material can weigh about as much as a mountain on Earth. Additionally, black holes, while not traditionally measured by density in the same way, can also have immense gravitational effects that suggest extreme density within their event horizons.
Neutron stars and black holes.
High-mass stars might become black holes, if the remaining matter (after the supernova explosion) is sufficiently large.
The density of a black hole is extremely high, as all its mass is concentrated in a very small space. This makes black holes one of the densest objects in the universe. Compared to other celestial objects like stars or planets, black holes have much higher density due to their immense gravitational pull.
No, black holes are not infinite in size and mass. They have a finite size and mass, but their density is extremely high, leading to their strong gravitational pull.
Black holes are extremely dense, with a mass packed into a very small volume. Their density is much higher than that of other celestial objects in the universe, such as stars or planets. This high density is what gives black holes their intense gravitational pull, which can even trap light.
Black holes are extremely dense, with a mass packed into a very small volume. This high density creates a gravitational pull so strong that not even light can escape from them.
Black holes can contain anything that has crossed their event horizon, including matter, radiation, and even light. Once inside a black hole, objects are crushed to an extremely high density at the singularity, a point of infinite density at the center of the black hole.
Black holes are incredibly dense compared to other celestial objects in the universe. Their density is so high that the gravitational pull they exert is extremely strong, making them one of the most mysterious and fascinating objects in space.
The density of a black hole is extremely high, as it is a region of space where gravity is so strong that nothing, not even light, can escape. The density of a black hole is much higher than that of other celestial objects, such as stars or planets, due to its compact size and immense gravitational pull.
A black hole is an object with extremely high density, where matter is packed tightly together. Black holes have such strong gravitational pull that not even light can escape from them, making them essentially invisible to the naked eye.
When a star is at his end of his life, it expands. It will gradually expand till its own weight is to big to carry and the star implodes. A black hole isn't a hole, as many people think, but a object with an extremely high density, with such a high gravitational force that not even light itself can escape from it. The imploded star is such an object; it is a object with an extremely high density and therefore a large gravitational force. Only big stars can form black holes, cause they only have a large enough mass to form such a high density.

The best answer to your question is that black holes are super massive. Massive objects have high gravitational pull which means that they will pull objects, including sunlight, into the black hole if something enters the black hole's event horizon.As opposed to common lore, black holes are not giant "vacuum cleaners" which roams around the universe destroying everything it comes near. Most galaxies are believed to harbor massive black holes and the stars in the galaxy are typically orbiting the the black holes instead of falling into them. In some cases, galaxies are disturbed(for example if two galaxies collide), and some solar systems may be pushed into the path of the black holes which will then "suck them in".
