What do astronomers think that the areas around blackholes give off?

Astronomers think that the areas around black holes suck everything in like when a tub drains. But black holes are large amounts of matter that is packed into a small area.


What kind of Astronomers study black holes?

specifically, "astronomers" that study black holes are called cosmologists.


How do astronomers use evidence to detect black holes?

Astronomers use evidence such as the behavior of nearby stars and gas, as well as the bending of light around invisible objects, to detect the presence of black holes in space.


Are black holes known?

Yes, black holes are known and regarded by many scientists, astronomers, and physicists.


How do you know there are black holes?

Because the astronomers can detect that a star is being whirled around in space, or space is being distorted.


What is the thing astronomers have been able to proove that it exists?

How do astronomers discover black holes in the universe?

Astronomers discover black holes in the universe by observing the effects they have on nearby objects, such as stars and gas. They use telescopes to detect X-rays and other forms of radiation emitted by black holes, as well as studying the gravitational influence they have on surrounding matter.


Are there black holes on the sun?

There are no black holes but there are dark areas known as Sun spots.


What subjects other than astronomy would astronomers have to study in order to discover black holes?

Astronomers studying black holes would typically need to study physics, particularly in the areas of general relativity, quantum mechanics, and thermodynamics, to understand the nature and behavior of black holes. They may also need to study astrophysics, cosmology, and computational modeling to analyze observational data and simulate black hole interactions with their surroundings.


Why do astronomers have difficulty studying the black hole?

Black holes do not emit light, so we cannot observe them directly


Where is the black hole now?

Astronomers say that there are several, possibly many, black holes, all a long way from Earth.
