How many black holes are known to exists at the time of writing?

The number of known black holes is constantly increasing. As of 2021, there are over 100 known black holes, including those that have been observed directly and those that have been inferred from observations of their gravitational effects on other objects.

What is the most massive black hole known to exist?

The most massive black hole known to exist is the supermassive black hole at the center of the galaxy M87, which has a mass of about 6.5 billion times that of the Sun. This black hole is located about 55 million light-years away from Earth and is one of the largest and most massive black holes known to exist.

What is the smallest black hole known to exist?

The smallest black hole known to exist is the black hole that was formed when a star exploded in a supernova, which is believed to have occurred about 10,000 years ago. This black hole is estimated to have a mass of about 3.5 times that of the Sun and is located about 1,000 light-years away from Earth.

How many black holes are there in the Milky Way?

There are believed to be millions of black holes in the Milky Way, including both stellar-mass black holes and supermassive black holes. The majority of these black holes are believed to be stellar-mass black holes, which are formed when a massive star collapses at the end of its life.

What is the closest black hole to Earth?

The closest black hole to Earth is the black hole that was formed when a star exploded in a supernova, which is believed to have occurred about 10,000 years ago. This black hole is estimated to have a mass of about 3.5 times that of the Sun and is located about 1,000 light-years away from Earth.

How do we know that black holes exist?

Black holes are known to exist based on a combination of observational evidence and theoretical predictions. Observational evidence for black holes includes the presence of gravitational redshift, which is the phenomenon in which the wavelength of light is stretched as it moves away from a massive object, and the presence of gravitational lensing, which is the bending of starlight by gravity. Theoretical predictions for black holes are based on the
