The universe is still a mystery that needs to reveal. Scientists are working consistently to know the secrets behind the various concepts of the universe. One of the major mysteries that have always attracted the scientists is the black hole facts. Black holes and their related information has always been a mystery that requires detailed and accurate examination of the various facts of the universe. There are many facts that the scientists are still looking answers for.
One of the concerning questions that are still a big question for the scientists is the fact that who discovered black holes. Many researchers are carried for finding some more information about the black holes. Let us begin with understanding the very basic of the concept: What is black hole and how it is formed?
What is a black hole?
A black hole is that place in the space where there is maximum gravity. The gravity pull is so high in the black hole that it even resists light to pass through it. It generally happens in the situation when a star is expected to die. As the black hole does not allow light to pass through, they cannot be easily detected. It can be observed by analyzing the behaviour of the stars that are acting differently than the rest of the stars in the universe. This different behaviour of the nearby stars is generally observed using a telescope with special tools. If you are thinking what is inside a black hole then there is just and just more of gravity that is within the black hole.
How big is the black hole?
According to black hole NASA, the black hole can be big or small depending on its size. The smaller black holes can be of the size of an atom but offer the capacity to have a large amount of masses. The small black holes are difficult to detect because of their size.
On the other hand, there are some big black holes. One of the bigger size black holes are known as ‘stellar.’ These black holes have 20 times more mass than the mass of the Sun. Thus, this indicates the size of these black holes. Earth’s galaxy is full of many stellar.
The largest size black holes are known as supermassive. These black holes are actually more mass than the combined mass of 1 million Sun. A supermassive black hole is always found in the centre of every large galaxy. The earth’s galaxy supermassive black hole called Sagittarius has a total mass of 4 million Sun and can hold many million Earth-like bodies.
There is still a major question that is to determine how are black holes formed. Every year many pieces of research are done that helps the scientist to know black hole in much better details and comes up with some new information about the same. It is expected that with the information concerning black hole, many more facts about the universe will be disclosed and scientists will be able to understand the universe in a better way.
