What profession studies black holes?

Astronomers
Astronomers study the universe and the objects within it. For example, they may study planets, stars, galaxies, asteroids, black holes, and other celestial bodies.

Why is it hard for humans to study black holes?

The very thing that characterizes a black hole also makes it hard to study: its intense gravity. All the mass in a black hole is concentrated in a tiny region, surrounded by a boundary called the “event horizon”. Nothing that crosses that boundary can return to the outside universe, not even light.

What is the disadvantage of black hole?

These black holes are dark most of the time, but when their gravity pulls in nearby stars and gas, they flare into intense activity and pump out a huge amount of radiation. Massive black holes are dangerous in two ways. If you get too close, the enormous gravity will suck you in.

What is the importance of black holes in physics?

Black Holes may also be fundamental to properly understanding gravity which is very useful. In fact it is necessary to include corrections from General Relativity (which has been much better understood through the study of Black Holes) to the Global Positioning Satellites in order to make them accurate to more than a few metres.

Is it true that black holes are dangerous to humans?

I guess it is true that there is unlikely to be any event in the near future endangering human life that involves Black Holes. However, if that were the criteria upon which we based what we should study there would be no computers for me to tell you this!

Is this the first image of a black hole?

“Astronomers have detected many black holes since the 1970s, but in each case, only indirectly,” added Charles Alcock, the Donald H. Menzel Professor of Astrophysics and director of the CfA. “This is the first time we have an image of a black hole itself.

What is an intermediate-mass black hole?

In the mass range between stellar-mass and supermassive blackholes – that is hundreds to hundreds-of-thousands of solar masses – are intermediate-mass black holes. Astronomers have spotted evidence for a handful of candidates, but none have been conclusively detected.
