New Study Suggests Black Holes Might Not Always Come from Stars

Although physicists for a long time thought that black holes are formed by remnant of stars, a group of researchers has found evidences of direct formation of black holes that do not need not to emerge from a star.

In the latest study, published in the Astrophysical Journal Letters Physics & Astronomy professors Shantanu Basu and Arpan Das gave an explanation for the previously observed supermassive black holes that are present since the earliest stages of the universe. According to the researchers, the discovery is based on the assumption that supermassive black holes are formed over a quick period of time and then stop. However, the new theory contradicts the current opinion that black holes are formed when a center of a massive star collapses on itself.

“This is indirect observational evidence that black holes originate from direct-collapses and not from stellar remnants,” said Basu.

The mathematical model based on the researchers’ assumption showed that supermassive black hole could form over a limited period of time and undergo rapid exponential growth of mass.

Basu continued, “Supermassive black holes only had a short time 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, then their production came to a halt. That’s the direct-collapse scenario.”

The scientists hope that their latest findings can be used to explain the formation of black holes that exist since the early times in the universe. However, the group admitted that further studies will need to be conducted in future to prove the theory’s validity.
