How big are black holes and what factors determine their size?
Black holes can vary in size, with some being as small as a single atom and others being millions of times larger than our sun. The size of a black hole is determined by the amount of mass it has, with more massive black holes being larger. Additionally, factors such as the rate at which the black hole is consuming matter and its age can also influence its size.
Can a black hole explode, or is it a stable entity in the universe?
Black holes are stable entities in the universe and do not explode. They are formed when a massive star collapses under its own gravity. The intense gravitational pull of a black hole prevents it from exploding.
Do galaxies have black holes in the center?
Yes, many galaxies have supermassive black holes at their centers.
Do all galaxies have black holes?
Not all galaxies have black holes. While many galaxies, including our own Milky Way, have supermassive black holes at their centers, there are also galaxies that do not have black holes. The presence of a black hole in a galaxy depends on various factors such as the size and age of the galaxy.
Do all galaxies have black holes in the center?
Not all galaxies have black holes in their centers, but many large galaxies, including our own Milky Way, are believed to have supermassive black holes at their centers.
If a black hole become visible what will be its size if it is at a distance equal to sun?
First and the crux here is that, black holes can never become visible(that's why they are called black holes) because the gravity is so insane that it doesn't even allow light to pass! Secondly, if by mistake it was going to become visible then it would appear like any other ordinary star, because black holes have a diameter, on an average, of about 100kms. for more info about blackholes u can refer intermediate physics textbook
Is the universe being consumed by the galactic black holes?
Even though black holes suck through parts of the universe, the universe is inevitably big, and growing so as the universe is being sucked into another dimension by black holes, it is also expanding.
Are black holes invisable?
Yes and no. It is rather hard to explain, because black holes are so dark and black that no living creature can see them, which in a sense makes them invisible, but you can also see where a black hole is because it sucks in light, too, so that would also, in a sense make it visible, but the my main answer would be, no black holes are not invisible.
Who discovered black holes 1st?
Philosopher and scientist John Michell gets credit as being the first known to propose the existence of black holes, which he called "dark stars." He pointed out that if a star were heavy enough, its gravity could be so great that light might not be able to escape and so it would not be visible.
Will there be a black hole every day?
No, black holes are not created daily. Black holes are formed from the remnants of massive stars that have undergone supernova explosions or from the collisions of other black holes. The rate at which new black holes are formed in the universe is relatively low.
What is a tiny black hole called?
Black holes are generally categorized into three buckets - the largest being called supermassive, the 'medium' being associated with stellar evolution and called 'stellar mass' black holes, and the smallest or tiny ones called "microscopic" black holes.
What is bigger a quasar or a black hole?
It depends, Black holes can go from being microscopic to supermassive black holes that entire galaxies revolve around. It all depends on which black hole and which quasar.
What does it look like to go near a black hole?
You might think it would look amazing and scary! But... no. Black holes suck in light so it is not visible.
How big are black holes and what factors determine their size?

Additionally, factors such as the rate at which the black hole is consuming matter and its age can also influence its size.
Are there galaxies with no supermassive black holes?
It is currently believed that most, if not all, galaxies contain supermassive black holes at their centers. These black holes can vary in size, with some being relatively small and inactive. However, the presence of supermassive black holes in galaxies is a common feature in the universe.
What were black holes before they turned into black holes?
stellar black holes were stars (these are large)primordial black holes were pieces of the big bang (these are microscopic)
Astronomers think that the areas around black holes give off?
A. visible light B. Nebulas C. Helium or D. Xrays
