Unveiling the Secrets of a Unique ‘Naked’ Black Hole: How It Redefines Our Understanding of the Universe | Quanta Magazine

A remarkable black hole has been discovered in the early universe. This one is different from anything we’ve seen before. Known as QSO1, it weighs around 50 million times more than our sun and doesn’t have many stars rotating around it. This challenges our long-held beliefs about how black holes and galaxies form.

“This is off the scale,” said Roberto Maiolino, an astrophysicist from the University of Cambridge. He played a key role in studying QSO1, calling it “exciting and highly informative.”

Dale Kocevski, an astronomer from Colby College, noted that this discovery challenges our understanding of cosmic beginnings. Traditionally, scientists thought black holes formed after stars collapsed and merged in established galaxies. However, QSO1 seems to exist independently without any visible parent galaxy.

The James Webb Space Telescope (JWST) made this discovery possible. Launched to explore the universe’s early moments, JWST has been revealing wonders from the first billion years after the Big Bang. The telescope’s capabilities allow it to investigate objects like QSO1, which might redefine our cosmic history.

Yet questions remain about how QSO1 came to be. Some experts speculate about a theory proposed by Stephen Hawking in 1971, suggesting that black holes originated in the primordial state of the universe. If this is true, QSO1 could have been lurking in darkness since the universe’s inception, waiting to be discovered.

The JWST has also identified many other mysterious objects, often called “little red dots.” While astronomers aren’t sure if these are all black holes, they highlight the still-murky understanding of the universe’s early years. John Regan, a theorist at Maynooth University, expressed the sentiment in the field: “We don’t know much yet.”

Lukas Furtak, an astronomer from Ben-Gurion University in Israel, marveled at QSO1. He spotted it while examining images from JWST, where light from galaxies was bent by gravity, revealing hidden objects in the early universe. The three red dots of QSO1 stood out because they didn’t distort like galaxies would.

After extensive observation, Furtak’s team determined that QSO1 is likely a glowing black hole, packed into a span of about 100 light-years. This view captures it when the universe was just 750 million years old, a tiny fraction of its current age of nearly 14 billion years.

The discovery of QSO1 is a huge leap in understanding our universe. As the exploration continues, we may uncover even more about how black holes and galaxies interact and evolve in the vast cosmos. For now, QSO1 stands as a beacon of mystery, propelling scientists to rethink the fabric of the universe.
