What Is The Densest Black Hole?

Astronomers have discovered what may be the most massive black hole ever known in a small galaxy about 250 million light-years from Earth, scientists say.

The supermassive black hole has a mass equivalent to 17 billion suns and is located inside the galaxy NGC 1277 in the constellation Perseus.28 Nov 2012

What is the density of black holes?

The density at the center of a black hole is infinite (it’s a famous “singularity”, which leads to difficulties in modern cosmology). On Earth, densities range from 10-4 g/cm3 for light gases to 0.001 g/cm3 for aerogels and up to the heaviest substance, osmium, with a density of 22.61 g/cm3.14 Oct 2019

Are black holes the densest thing in the universe?

Black holes are some of the strangest, most wondrous objects in all the Universe. With huge amounts of mass concentrated into an extremely small volume, they inevitably collapse down to singularities, surrounded by event horizons from which nothing can escape. These are the densest objects in the entire Universe.20 Dec 2018

How heavy are black holes?

A typical stellar-class of black hole has a mass between about 3 and 10 solar masses. Supermassive black holes exist in the center of most galaxies, including our own Milky Way Galaxy. They are astonishingly heavy, with masses ranging from millions to billions of solar masses.

Can black holes die?

The black hole would then lose the rest of its mass in a short amount of time as abrupt explosions—we can detect these explosions as gamma ray bursts. The end. So, yes, black holes do die, and they do so when the theories of the extremely large come together with the theories of the very small.24 May 2013

Is the universe a black hole?

In the version as originally proposed by Pathria and Good, and studied more recently by, among others, Nikodem Popławski, the observable universe is the interior of a black hole existing as one of possibly many inside a larger parent universe, or multiverse.
