Megasuns containing helium and hydrogen that were huge

In summary, some scientists believe that Megasuns, which were enormous stars made up of helium and hydrogen, may have been the origin of supermassive black holes in the first few billion years of the universe. However, there is also another theory that suggests supermassive black holes are just very old black holes that have accumulated enough mass.

I know that in early time, in the first few billion years, there were stars containing helium and hydrogen that were huge. These were called Megasuns. Can someone tell me if these were the origin of SuperMassive Black holes.

Thank You

Megasuns are one of our theories attempting to explain supermassive black holes. Some scientists think that very large clouds of gas clumbed into enormous stars which collapsed very quickly under their own gravity (the force produced by fusion not being enough to hold them open) and so formed supermassive black holes. You need a megastar to do this because very large stars blow away much of their mass before they collapse into black holes which prevents them from becoming supermassive black holes.

The other explanation for supermassive black holes is just that they are very old black holes that have accumulated enough mass to be classified as supermassive.

Hope that helped :)

Related to Megasuns containing helium and hydrogen that were huge

1. What are megasuns containing helium and hydrogen?

Megasuns containing helium and hydrogen are large, extremely hot stars that are formed from the gravitational collapse of massive gas clouds. They are much larger and hotter than our sun, which is mainly composed of hydrogen.

2. How do megasuns containing helium and hydrogen form?

Megasuns containing helium and hydrogen form through the process of gravitational collapse, where a large cloud of gas and dust contracts due to its own gravity. This causes the temperature and pressure at the core to rise, eventually leading to nuclear fusion and the formation of a star.

3. How big are megasuns containing helium and hydrogen?

Megasuns containing helium and hydrogen can vary in size, but they are typically much larger than our sun. They can range from 10 to 100 times the size of our sun, with some even reaching sizes of over 1000 times that of our sun.

4. What is the role of helium and hydrogen in megasuns?

Helium and hydrogen are the two main elements that make up megasuns. Hydrogen is the primary fuel for nuclear fusion, which is the process that produces the immense amount of energy that allows the star to shine. Helium is created as a byproduct of this fusion process and also helps to maintain the star's stability.

5. Can we see megasuns containing helium and hydrogen in our night sky?

No, we cannot see megasuns containing helium and hydrogen in our night sky. These stars are located in distant galaxies and are too far away to be seen with the naked eye. They can only be observed through powerful telescopes and other astronomical instruments.
