It most certainly is. A nebula is a cloud of dust, hydrogen, and other gases where a black hole is a region of space from which nothing, not even light, can escape

Is your galaxy bigger than a black hole?
A galaxy is bigger than a black hole.
How soon will humans know if the earth is in a black hole?
Never, because if we can thrive in it than we are not in a black hole
Are black holes the strongest object in space?
That depends exactly how you interpret the term "strong". In its vicinity, the black hole distorts space more than anything that is NOT a black hole; so much that nothing can get out of the black hole. But at some standard distance, a galaxy, for example, would have more gravitational attraction than a black hole, simply because it has more mass. At least, so far no black hole of the mass of an entire galaxy has been found.That depends exactly how you interpret the term "strong".

Can a black hole die or fade away?
It is believed that a black hole will slowly evaporate. But for a black hole that has the mass of a star, this will take much, much longer than the current age of the Universe.
Why does a black hole have more gravity then the star it once was despite having the same or less matter?
This is a common cause of confusion. In a way, if no mass got lost in the creation of a black hole, then it will have exactly the same gravity than before. For example, if our Sun converted to a black hole (not that it is planning to do so...), our Earth would continue orbiting this black hole, in the same orbit as before. What makes a black hole different is that the mass is very concentrated; so, it is possible to get much closer to the black hole - and remember that gravity gets stronger at shorter distances.
Is a black hole stronger than the crab nebula?
I'm not sure what you mean, but in luminescence, the crab nebula trumps black holes infinitely. However, if the two met, the black hole would still be around the next day.
Is a star bigger than a nebula?
A nebula is an interstellar cloud of dust, hydrogen and helium gas and plasma. A Nebula can be over 2.5 million light years across. The largest star is a mere 1.7 billion miles in diameter
Does a nebula ever die?
A nebulae can only die if it's right by a black hole or if all the stars that can be formed are formed which uses up the nebulae
Is your galaxy bigger than a black hole?
A galaxy is bigger than a black hole.
How is the formation of a normal black hole different from the formation of a supper-massive black hole?
It is not yet known for sure how a supermassive black hole acquires the enormous mass it has. It is possible that it starts as a normal black hole, and then gets more mass. It is also possible that from the start, a much larger amount of mass than in a normal black hole collapses.
Is the sun bigger then a black hole?
Black holes can be many different sizes. Therefore, there are some black holes that are bigger than the sun, and there are some that are smaller than the sun.
Does Rigel have a bigger black hole than Sirius?
I don't think that either of these stars "have" a black hole.
Is a black hole small?
Yes. It's physically impossible for anything to be smaller than a black hole.
How soon will humans know if the earth is in a black hole?
Never, because if we can thrive in it than we are not in a black hole
Is the Milky Way much smaller than the black hole?
No - The volume of the Milky Way galaxy is larger than the volume of its host black hole. The accumulated mass of the Milky Way galaxy is greater than the mass of its host black hole. The density of the Milky Way galaxy is much smaller than the density of its host black hole.
What is different to black holes and earth?
There are spectacular differences between black holes and Earth. Earth is a planet; a black hole is not. Usually black holes are remnants of stellar evolution, created at the end of a star's lifespan when its fuel is exhausted and collapses, producing a region of spacetime where escape velocity is greater than the speed of light; Earth by contrast is believed to have formed from a proto-nebula not (directly) from a star. The escape velocity of Earth is much less than the speed of light, and it lacks sufficient mass to become a black hole. A black hole has a singularity of infinite density; Earth has no such structure and could not approach infinite density. Earth reflects light, a black hole does not. The Earth's gravitaional radius is much smaller than its Schwarzschild radius; a black hole's is equal (or larger). Black holes evidence a type of matter known notionally as exotic which defies our current physical models; Earth's does not. Black holes bend space sufficiently to have a photon sphere; the Earth cannot have one.. etc. One coincidental similarity is that much of Earth's matter is a product of a supernova explosion (for example, elements with atomic numbers higher than that of iron); a black hole can also be created by matter associated with supernova explosion.
Is a neutron star or a black hole bigger?
A black hole has more mass than a neutron star, but if you are comparing volume it would depend on the mass of the black hole. A neutron star is estimated to be about 14 miles in diameter, which is larger than the event horizon of a black hole up to about 3.8 times the mass of the sun. A more massive black hole will be larger.
