How massive can an Ultramassive black hole get?

about 10 billion solar masses
There is no theoretical upper limit to the mass of a black hole. However, astronomers have noted that the ultra-massive black holes (UMBHs) found in the cores of some galaxies never seem to exceed about 10 billion solar masses.

How long will the biggest black hole last?

This radiation reduces the mass and energy of black holes, causing them to shrink and ultimately vanish. If black holes evaporate via Hawking radiation, a supermassive black hole with a mass of 1011 (100 billion) M ☉ will evaporate in around 2×10100 years.

How big can a black hole get NASA?

Peppered throughout the Universe, these “stellar mass” black holes are generally 10 to 24 times as massive as the Sun. Astronomers spot them when another star draws near enough for some of the matter surrounding it to be snared by the black hole’s gravity, churning out x-rays in the process.

Where is the largest black hole in the Milky Way?

Massive black hole discovered near heart of the Milky Way. This article is more than 2 years old. Astronomers find evidence of enormous black hole one hundred thousand times more massive than the sun in a gas cloud near the galaxy’s centre.

How do supermassive black holes grow?

“We think some of those black holes are the seeds from which the much larger supermassive black holes grow to at least a million times more massive. That growth should happen in part by mergers with other black holes and in part by accretion of material from the part of the galaxy that surrounds the black hole.

Do black holes form at the center of galaxies?

Astronomers believe supermassive black holes probably lurk in the centers of most large galaxies. These gargantuan black holes can gather swirling disks of material around them as their gravity attracts stars and gases.

When did our galaxy’s supermassive black hole explode?

The research also points to the supermassive black hole in our galaxy’s center, called Sagittarius A* or Sgr A*, as the responsible party. The team also estimated when this event occurred. Their data put the outburst at 3.5 million years ago, give or take a million years.
