Recent research suggests that the black hole at the center of our galaxy, Sagittarius A*, may be spinning at an incredibly high speed, almost reaching its maximum possible rotation rate.
Scientists, led by Michael Janssen from Radboud University in the Netherlands, utilized data from the Event Horizon Telescope (EHT) to study Sagittarius A*. Employing artificial intelligence to analyze the complex data, they discovered intriguing details about the black hole’s characteristics.
By simulating millions of black holes using mathematical models and training a neural network with these simulations, the researchers were able to determine that Sagittarius A* is spinning at 80 to 90 percent of its maximum speed. Additionally, the AI highlighted discrepancies in existing magnetic field models, indicating the need for further refinement in understanding the black hole’s properties.
Dimitrios Psaltis from the Georgia Institute of Technology expressed surprise at the precision of these findings, emphasizing the role of AI in enhancing our knowledge of celestial objects like black holes. Similarly, Yosuke Mizuno from Shanghai Jiao Tong University acknowledged the advancements but noted the ongoing need for improvement in theoretical models.
Despite the challenges associated with utilizing AI in astronomical research, experts agree that machine learning is reshaping how we study phenomena like black holes. Psaltis emphasized the importance of integrating data and models effectively, with AI playing a crucial role in this process.
Continual validation and verification of AI’s findings are essential, with Janssen’s team conducting extensive tests to ensure the accuracy of their results. As they analyze data from different observation periods and new telescopes, further insights into Sagittarius A* and other cosmic entities are anticipated.
