The only thing more terrifying than the space-time devouring black holes we see in movies are the real things! Hollywood hasn't come close to conveying the mind-bending reality of these behemoths. With gravity so intense that not even light can escape, they remain one of the greatest challenges for physicists trying to unify two major theories of the universe—Einstein's general theory of relativity and quantum mechanics. Now, scientists in the Netherlands have created an artificial black hole in a lab, and something unexpected happened: it started glowing.

Researchers from the University of Amsterdam built a simulated black hole using a chain of atoms arranged in a single file to mimic the event horizon—the boundary beyond which nothing can return. Their goal was to study a phenomenon known as "Hawking radiation," first proposed by Stephen Hawking in 1974. But what they observed went beyond their expectations, offering a potential breakthrough in our understanding of quantum gravity.

A glowing discovery

In simple terms, Hawking radiation is a type of energy that, theoretically, should be emitted by black holes due to disruptions in quantum fluctuations at the event horizon, reports Science Alert. If Hawking's theory is correct, black holes don’t last forever. Instead, they slowly evaporate over time—though in reality, this process is too faint to be observed from Earth.

via GIPHY

However, when the researchers in Amsterdam simulated this effect, something unexpected occurred. Their artificial black hole started to glow. The radiation they observed appeared only when a portion of the atomic chain extended beyond the event horizon, suggesting that quantum entanglement plays a crucial role in generating Hawking radiation.

"This can open a venue for exploring fundamental quantum-mechanical aspects alongside gravity and curved spacetimes in various condensed matter settings."

— Researchers, Physical Review Research

Why this matters

One of the biggest unsolved problems in physics is the clash between general relativity and quantum mechanics. Einstein's theory explains gravity on a cosmic scale, treating space and time as a smooth, continuous fabric. Meanwhile, quantum mechanics describes the subatomic world, where particles behave probabilistically rather than following strict rules. The problem? These two frameworks don't align when it comes to black holes.

via GIPHY

A theory of "quantum gravity"—a way to unify these two systems—remains elusive. However, black holes may hold the key. If Hawking radiation can be confirmed, it would be a step toward bridging the gap between Einstein’s smooth spacetime and the bizarre, probabilistic nature of quantum physics.

The future of black hole research

While this artificial black hole isn’t the real thing, it gives scientists a controlled way to test theories that would otherwise be impossible to study in deep space. And the fact that the simulated black hole glowed when it wasn’t expected to means there could be more to Hawking radiation than we previously thought.

Past simulations of black holes have been conducted, but this experiment marks a significant step forward. By demonstrating that quantum entanglement is involved in the radiation process, the study could provide new insights into the true nature of black holes—and even the fate of our universe.

If Hawking radiation is real, it means black holes aren’t immortal. Over billions or even trillions of years, they could slowly shrink and eventually vanish, leaving behind only radiation. The discovery of a glowing artificial black hole may be the first step toward proving that theory.

Who knows? The next breakthrough in black hole physics might not come from space—but from a lab right here on Earth.

He was trapped in a 20-foot pit. Then he pulled off the ultimate escape.

A viral video from China has people questioning the laws of gravity—and then realizing it's all physics, skill, and a healthy dose of discipline. Posted on Xiaohongshu (also known as Rednote), the video shows a man inside a vividly colored pit, its vertical walls towering about 20 feet above him. There's seemingly no way out—until he starts running.

Scientists extracted a Pink Floyd song from brainwaves and it’s haunting

The concept of reading thoughts once belonged to the realm of science fiction, but breakthroughs in neural decoding are turning it into reality. This technology, which interprets brain activity into meaningful signals, has already allowed scientists to reconstruct words and images from brainwaves. Now, researchers at the University of California, Berkeley have taken it a step further. In August 2023, they managed to recreate a Pink Floyd song purely from brain activity, a discovery published in PLOS Biology that offers new insight into how the brain processes music.

A team led by Robert Knight and Ludovic Bellier conducted the study on 29 epilepsy patients at Albany Medical Center in New York who were undergoing brain surgery. While the patients were in the operating room, they listened to "Another Brick in the Wall, Part 1" by Pink Floyd. Electrodes placed directly on their brains recorded the electrical signals produced as they processed the song. Using artificial intelligence, Bellier later reconstructed the track based entirely on these neural recordings. The final result was hauntingly distorted yet unmistakably recognizable. "It sounds a bit like they’re speaking underwater, but it’s our first shot at this," Knight told The Guardian.

Why you look great in the mirror but awful in photos, according to science

The morning after a wild night of partying, the biggest fear often isn't regretting what you said, but how you'll look in your friends' tagged photos. Even if you left the house feeling like a 10, those awkward group selfies can make you feel like a 5, making you wonder, "Why do I look different in pictures?"

This strange phenomenon, amplified by selfies, is making people question their own mirrors. Are pictures the "real" you or is it your reflection? Have mirrors been lying to us this whole time??

Black holes are the universe’s ultimate mystery box—nothing gets out, and no one really knows what’s inside. But now, a group of scientists may have just pulled off something incredible: they built a black hole replica right here on Earth.

And not just for fun. This experiment could help explain one of the biggest cosmic puzzles of our time—Hawking radiation, the theory that black holes slowly lose energy by giving off faint particles at their edges.

5 body language habits that make you instantly more charming

The sayings, “Actions speak louder than words,” and “It’s not what you say, but how you say it,” are popular adages for good reason. Our silent body language speaks volumes, but we may not always be aware of what we’re saying with it. The way we hold ourselves, our gestures, and even how we make eye contact can make a huge difference in how people perceive us.

And that perception makes a difference. People form a first impression within seconds, and some research shows that traits like trustworthiness start to be judged within a tenth of a second of meeting someone.
