How were black holes proved?

Answer 1

What is arguably the best evidence for there being a black hole at the center of the Milky Way is the movement of some stars near the center of our galaxy. These stars are orbiting around a massive object that emits no visible radiation that we can detect. A black hole would "fill the bill" here. It would explain the movement of those stars, and the "invisibility" demonstrated by the object with the massive gravity strongly suggests a black hole.

Answer 2

Black holes were first theorized by Albert Einstein's theory of general relativity. Today, their existence is indirectly proven through observations of the effects they have on surrounding matter, such as the gravitational lensing of light or the high-speed motion of stars around invisible objects. Direct imaging of a black hole's event horizon was achieved for the first time in 2019 by the Event Horizon Telescope collaboration.

Answer 3

Several stars have been observed to rotate an object in the center of our galaxy. From the characteristics of the rotation, the mass of the central object can be estimated. The distance of the orbiting stars put an upper limit on the object's size. According to current theories, the only possibility of having such a large mass in such a small volume is a black hole.

Answer 4

there is a back hole at the center of our Galaxy.Evidence that proves there is a super massive black hole at the center of the milky way is that scientist have been tracking the black hole approximately 4 million solar masses for over 16 years they released evidence of it in 2008.

Answer 5

The Hubble telescope took pictures of it on September 10, 1997, and many times since.

You can find quite a few pictures of them if you type in "Hubble black hole" or similar. Hope this helps! :)

=============================================

The existence of black holes has never been 'proved', and isn't likely ever to be

proved. It just happens to be the best explanation we have for a lot of things

that are observed.

If you 'type in' "Hubble black hole" or similar, you get a lot of fascinating articles

with loud headlined titles that are interesting to read. But whenever it gets to

"black hole", the phrase is always preceded by "suspected", "apparent", "theorized",

and things like that.

The Hubble telescope did not take a picture of a black hole. By fundamental

definition, a black hole emits no light or other radiation directly, so there's

nothing to photograph.

The Hubble, and other orbiting detectors, plus many earth-bound instruments,

have all imaged and studied matter and radiation in all parts of the cosmos,

going through all sorts of strange gyrations that can be explained by invoking

the existence of black holes.

Answer 7

In summary: gravitational effects. Galaxies rotate too fast for the amount of known matter; gravitational lensing; and other effects, all indicate there is about 5 times as much matter than what we know about.

Answer 8

Our galaxies all need the middle part of our galaxies the quasar which balances our galaxies and is one of the most powerful things in the universe we know. It is super energetic and everything around it which is the solar system it is in the middle of it makes it spin around it at almost the speed of light. Our solar system revolves around the quasar and the quasar keeps all the other solar systems in our solar system together including us.

Answer 9

Objects like planets or stars orbit more dense objects like the sun. We know that black holes exist because we can see stars orbiting and being sucked into what looks like nothing.

Answer 10

Yes, there is. Specifically, there are certain intense X-ray sources which can be explained nicely by black holes; other explanations don't work as well.
