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".

How does the escape velocity from a black hole compare with the speed of light?
The escape velocity of a black hole is equal or greater than the speed of light, so light cannot escape
Is sun larger than black holes?
It you define the size of a black hole by the size of its event horizon then yes, the sun is larger than most black holes. The sun has a radius of just under 700,000 kilometers, while a stellar mass black hole would have an event horizon between 8.8 and 44 kilometers. Supermassive black holes are a different matter. The black hole at out galaxy's center, at 3.7 million solar masses, would have a radius of about 10 million kilometers. A black hole of 12 billion solar masses, which likely does exist, would have a radius of 35 billion kilometers, about 5 times wider than the orbit of Pluto.
Is anything has a mass greater than black hole?
No, a black hole is a region of space with a gravitational pull so strong that nothing, not even light, can escape from it. Therefore, it is not possible for anything to have a greater mass than a black hole.
Which thing is dark more then night?
A Black Hole. Night is darker than day, but there is still artificial light and the light of celestial bodies. However, light cannot escape a black hole in space, so the area occupied by a black hole appears darker than night.
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
Is a black hole faster than light?
No, a black hole is not faster than light.
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.
Is a black hole small?
Yes. It's physically impossible for anything to be smaller than a black hole.
Does Rigel have a bigger black hole than Sirius?
I don't think that either of these stars "have" 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.
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.
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.
Could you survive a black hole if you were in something more dense than the black hole so you wouldn't get crushed?
there is no such thing as that
Does a nebula ever die?
Nebulas do not actually "die" in the sense that they are dynamic and ever-changing regions of space where new stars can be born. As stars within a nebula use up their fuel and eventually die, the nebula can disperse or be reshaped by the forces of the dying star. The material in a nebula can be recycled to form new stars and planetary systems.
