What is a supermassive black hole?
A supermassive black hole (SMBH or sometimes SBH) is the largest type of black hole, with its mass being on the order of millions to billions of times the mass of the Sun ( M ☉).
How big is supermassive black hole?
It has a diameter of about 78 billion miles. For perspective, that’s about 40% the size of our solar system, according to some estimates. And it’s estimated to be about 21 billion times the mass of our sun. So there you have it, black holes can be millions of times larger than suns and planets or as small as a city.
What is the biggest black hole in the universe?
Ton 618, the largest ultramassive black hole, appears at the very end of the video, which, at 66 billion times the mass of the Sun, is going to weigh very heavily on how we daydream about the cosmos moving forward.
Can you survive supermassive black hole?
Regardless of the explanation, we do know that it is highly unlikely that anyone entering a black hole would survive. Nothing escapes a black hole. Any trip into a black hole would be one way. The gravity is too strong and you could not go back in space and time to return home.
What is the deadliest thing in the universe?
Death by black hole Black holes are expected to form when a massive star dies. After the star’s nuclear fuel is exhausted, its core collapses to the densest state of matter imaginable, a hundred times denser than an atomic nucleus.
Can a black hole swallow Earth?
Will Earth be swallowed by a black hole? Absolutely not. While a black hole does have an immense gravitational field, they are only “dangerous” if you get very close to them.
What is a white hole NASA?
White holes are theoretical cosmic regions that function in the opposite way to black holes. Just as nothing can escape a black hole, nothing can enter a white hole. White holes were long thought to be a figment of general relativity born from the same equations as their collapsed star brethren, black holes.
What is the most massive black hole in the universe?
A new method to calculate the number of black holes. As the authors of the research explain: “This important result has been obtained thanks to an original approach which combines
How big is the biggest black hole in the universe?

What is the biggest black hole ever discovered?

This monster contains a colossal 66 billion times more mass than the sun and has an estimated diameter of 242 billion miles or 390 billion kilometers, making it more than 40 times the size of Neptune’s orbit.
What is the largest black hole ever recorded?
The monster black hole in galaxy cluster Abell 85 is roughly the size of our solar system, but packs the mass of 40 billion suns. The Abell 85 galaxy cluster, shown here, is home to the largest black hole known in the universe.
