Are black holes really the cookie monsters of the universe?

In summary, black holes are regions in space with strong gravitational pull that can trap all matter and light. They are formed when a massive star dies and its core collapses. While sometimes referred to as the "cookie monsters" of the universe, they do not actually consume objects. Once something enters a black hole, it cannot escape, although some theories suggest that information and particles may be able to escape through Hawking radiation. There are three main types of black holes: stellar, intermediate, and supermassive. Supermassive black holes are the largest and are commonly found in the centers of galaxies.

This is a public service:

1] Blurb: "For the first time, scientists spotted a black hole devouring a star in a distant galaxy. One of the rarest astronomical events, it's believed to happen only about once per 100,000 years per galaxy." That is the ENTIRE written content of the link.

2] It's a video "news" article.

3] It's content-free.

The BH is named Swift-J 1644+57 if anyone wants to read up on it.

clearwater, please, in the future supply an explanation, not just an inscrutable link.

FYI, a neutron star would induce similar effects on it's scale. They can and do rip matter from other stars and have their own accretion discs. The only thing special about a black hole is that they are more massive and compacted into an area of space small enough so it that causes them to have an event horizon where light cannot escape once inside it.
 

1. What is a black hole?

A black hole is a region in space where the gravitational pull is so strong that nothing, including light, can escape from it. This creates a black void in the universe.

2. How are black holes formed?

Black holes are formed when a massive star dies and its core collapses under its own gravity. The core becomes so dense that it creates a strong gravitational pull, trapping all matter and light within it.

3. Are black holes really the cookie monsters of the universe?

No, this is just a fun analogy to help explain the concept of a black hole. While black holes do have a strong gravitational pull, they do not actually consume objects like a cookie monster.

4. Can anything escape from a black hole?

Once an object crosses the event horizon of a black hole, it cannot escape. However, some theories suggest that information and particles can escape through Hawking radiation.

5. Are there different types of black holes?

Yes, there are three main types of black holes: stellar, intermediate, and supermassive. They vary in size and mass, with supermassive black holes being the largest and most commonly found in the centers of galaxies.
