What else can I help you with?
Do mini black holes exist?
yes. some black holes are predicted to be the size of an electron.
Are black holes infinite in size and mass?
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.
How fast can black holes go?
there is no exact answer, different black holes have different speeds, but all black holes can crush 1 tonne of metal into a size of a pebble
Are black holes the size of stars?
Except for supemassive black holes, no. Most black holes have about the same mass as a star, but the event horizon is only a few miles across.
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.
Do medium size stars become black holes true or false?
False. Only the most massive stars will become black holes.
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.
How does the size of the central black hole relate to the size of a galaxy?
Roughly speaking, the larger galaxies tend to have larger central black holes.
Do medium size stars become black holes?
No. They do not have enough mass to become black holes. Depending on the mass they will either become white dwarfs or neutron stars.
Can black holes grow and how?
Black holes can increase in mass (and therefore size; the diameter of a black hole's event horizon is directly proportional to its mass) by accretion, or taking in additional matter and/or energy.
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.
Are there black holes the size of stars?
The relevant magnitude is mainly the black holes' mass. Since black holes are the result of collapsing stars, yes, there are black holes with the mass of a star.The diameter is usually taken as the diameter of the event horizon. This diameter is directly proportional to the mass; a supermassive black hole such as Sag A* has a diameter comparable to that of a large star.
