Scientists Discover Way to Send Information into Black Holes Without Using Energy

For years, scientists believed that adding even one qubit (a unit of quantum information) to a black hole needed energy. This was based on the idea that a black hole’s entropy must increase with more information, which means it must gain energy. But a new study by Jonah Kudler-Flam and Geoff Penington changes that thinking. They found that quantum information can be teleported into a black hole without adding energy or increasing entropy . This works through a process called black hole decoherence , where “soft” radiation — very low-energy signals — carry information into the black hole. In their method, the qubit enters the black hole while a new pair of entangled particles (like Hawking radiation) is created. This keeps the total information balanced, so there's no violation of the laws of physics. The energy cost only shows up when information is erased from the outside — these are called zerobits . According to Landauer’s principle, erasing information always needs energy. But ...

Black Holes That Never Dies

Black holes are powerful objects in space with gravity so strong that nothing can escape them. In the 1970s, Stephen Hawking showed that black holes can slowly lose energy by giving off tiny particles. This process is called Hawking radiation . Over time, the black hole gets smaller and hotter, and in the end, it disappears completely. But new research by Menezes and his team shows something different. Using a theory called Loop Quantum Gravity (LQG) , they studied black holes with quantum corrections. In their model, the black hole does not vanish completely. Instead, it stops shrinking when it reaches a very small size. This leftover is called a black hole remnant . They also studied something called grey-body factors , which affect how much energy escapes from a black hole. Their findings show that the black hole cools down and stops losing mass once it reaches a minimum mass . This new model removes the idea of a “singularity” at the center of the black hole and gives us a better ...

Meet Astro, the World’s Smartest Doberman Robodog That Smell Trouble Before It Happens

Imagine a dog that can not only sit, stay, and lie down but also detect explosives, recognize faces, respond to distress calls, and even help during disasters. Sounds like a character from a sci-fi movie, right? Well, meet Astro , a real-life robodog developed by scientists at Florida Atlantic University (FAU) . He’s not your typical robotic toy—Astro is powered by deep learning and artificial intelligence (AI) , designed to perform complex tasks that could one day save lives. In this article, we will dive into what makes Astro so special, how he works, what he can do, and how he could help in making the world a safer and smarter place. What is Astro? Astro is a four-legged, intelligent robot dog developed at FAU’s Machine Perception and Cognitive Robotics Laboratory (MPCR) . He was built using an open-source quadruped robotic platform provided by Ghost Robotics , and is powered by advanced AI technology. Unlike other robotic dogs that simply follow pre-set commands, Astro can...
