It would be difficult for even the brainiest scientist to explain supermassive black holes fully. It is widely believed that they are found at the center of every galaxy, including our own. The explanation for the existence of a black hole is a tricky one. Science theorizes that the collapse of a giant star causes such space phenomena to exist.
How a supermassive black hole is born, maybe
This theory involves stars, and it is kind of tricky, so bear with me:
- The collapse of a star forms a black hole
- For example, a star 5 times bigger than the Sun will expire when it is out of fuel
- A star’s burn is caused by nuclear fusion, and this creates outward pressure
- A sun has gravity as well caused by its own mass, an inward force
- These forces serve to balance each other out
- When there is no more fuel, there is no more fusion so no more outward pressure
- As a result, a massive explosion happens called a hypernova
- An explosion so powerful that it collapses on itself
- This forms the singularity no one understands
Science currently believes that this process creates a singularity. They grow to massive sizes by feeding on the matter over time. But science has a problem with its own explanation, stating that this process takes a really long time and that leaves room for error.
Supermassive black holes might not be the results of collapsing star
Astronomers have made some recent discoveries that do not line up with their current theories. This year 83 supermassive black holes were discovered. These are quite old. Old enough that they don’t quite fit into the before-mentioned theory.
It is believed that these many black holes were created 690 million years after the Big Bang. So if they came into being during this time frame, they would have had enough time to form from dying stars.
A couple of researchers Western University in Ontario, Canada, have come up with another theory. They say: “Supermassive black holes only had a short period where they were able to grow fast and then at some point, because of all the radiation in the universe created by other black holes and stars, their production came to a halt. That’s the direct-collapse scenario.”
