And it's astonishing: 40,000,000,000,000,000,000, or 40 quintillion, stellar-mass black holes populate the observable universe, making up approximately 1% of all normal matter, according to the new estimate. So how did the scientists arrive at that number?And it's astonishing: 40,000,000,000,000,000,000, or 40 quintillion, stellar-mass black holes populate the observable universeobservable universeThe comoving distance from Earth to the edge of the observable universe is about 14.26 gigaparsecs (46.5 billion light-years or 4.40×1026 m) in any direction. The observable universe is thus a sphere with a diameter of about 28.5 gigaparsecs (93 billion light-years or 8.8×1026 m).https://en.wikipedia.org › wiki › Observable_universeObservable universe - Wikipedia, making up approximately 1% of all normal matter, according to the new estimate.

Has a black hole been found?
A Black Hole has been Found Lurking Just Outside the Milky Way. Astronomers have found a smaller, stellar-mass black hole lurking in a nearby satellite galaxy of our own Milky Way. This is the first time astronomers have used this detection method to reveal the presence of a black hole outside of our galaxy.15 Nov 2021
Who proved black holes exist?
Roger Penrose (left) proved black holes are real objects. Andrea Ghez (center) and Reinhard Genzel (right) showed that one weighing 4 million times as much as the Sun lurks in the heart of our galaxy. Since Penrose's advances, astronomers have found a wealth of evidence for black holes.
What was the latest black hole discovered?
Researchers using NASA's Chandra X-ray Observatory recently discovered a monstrous black hole that was "buried" in dust and gas in a dwarf galaxy, according to a statement by the Chandra team.Researchers using NASA's Chandra X-ray Observatory recently discovered a monstrous black hole that was "buried" in dust and gas in a dwarf galaxydwarf galaxyA dwarf galaxy is a small galaxy composed of about 1000 up to several billion stars, as compared to the Milky Way's 200–400 billion stars.https://en.wikipedia.org › wiki › Dwarf_galaxyDwarf galaxy - Wikipedia, according to a statement by the Chandra team.12 Jan 2022
Who discovered first black hole?
Albert Einstein first predicted the existence of black holes in 1916, with his general theory of relativity. The term "black hole" was coined many years later in 1967 by American astronomer John Wheeler.4 Dec 2021
When was the first black hole actually discovered?
After decades of black holes being known only as theoretical objects, the first physical black hole ever discovered was spotted in 1971.4 Dec 2021
Who discovered black holes in 1983?
Subramanian Chandrasekhar
How was the first black hole discovered?
After decades of black holes being known only as theoretical objects, the first physical black hole ever discovered was spotted in 1971. The EHT saw the black hole in the center of galaxy M87 while the telescope was examining the event horizon, or the area past which nothing can escape from a black hole.4 Dec 2021
