Great, until the mention of “directed energy”…

Researchers at the University of Maryland (UMD) have demonstrated a continuously operating optical fiber made of thin air.

The most common optical fibers are strands of glass that tightly confine light over long distances. However, these fibers are not well-suited for guiding extremely high-power laser beams due to glass damage and scattering of laser energy out of the fiber. Additionally, the need for a physical support structure means that glass fiber must be laid down long in advance of light signal transmission or collection.

New findings enable experimental studies to control and further develop the multiscale phenomena of complex interdependent materials.

Bar-Ilan University researchers Havlin and Frydman have demonstrated the “network of networks” theory using a controlled system of interdependent superconducting networks. The study confirms that coupled networks exhibit abrupt transitions under varying temperatures, validating Havlin’s 2010 theory. This groundbreaking research has significant implications across physics, materials science, and device applications, potentially leading to new developments in self-healing systems, sensitive sensors, and network metamaterials.

Metamaterials are engineered materials that have properties not usually found in nature.

Universal computation has significant real-world implications in fields such as computer science, physics, biology, and beyond. It is highly relevant to simulation metaphysics and its idea that the physical world could be a type of computer simulation.

This video is about the story of two geniuses, Albert Einstein and the famous logician Kurt Godel. It is about their meeting at IAS, Princeton, New Jersey, when they both walked and discussed many things. For Godel, Einstein was his best friend and till his last days, he remain close to Einstein. Their nature was opposite to each other, yet both of them were very good friends. What did they talk about with each other? What did they share? What were their thoughts? For Godel, Einstein was more like his guide and for Einstein, it was a great pleasure to walk with him.

In the first episode, we discover their first meeting with each other and the development of friendship between them.

This new solid hydrogen phase discovered by an international team of researchers followed the model’s presentation of hydrogen molecules under extreme conditions: to use a food analogy, their shape morphed from spheres stacked like a pile of oranges to something that more closely resembled eggs.

Hydrogen typically requires very low temperatures and very high pressures to form a solid. It was through a novel machine learning study of this particular phase change that the scientists came across the new molecular arrangement.

Time travel has long been a popular theme in movies, but scientists believe that the concept of time teleportation is unlikely in reality. However, they do not dismiss the possibility of time travel altogether. The laws of physics suggest that time travel may be possible, but the details are complex.

Physicists explain that traveling to the near future is relatively simple, as we are all doing it right now at a rate of one second per second. Additionally, Einstein’s special theory of relativity states that the speed at which we move affects the flow of time. In other words, the faster we travel, the slower time passes. Furthermore, Einstein’s general theory of relativity suggests that gravity also impacts the flow of time. The stronger the nearby gravity, the slower time goes.

Within a year, Karl Schwarzschild, who was “a lieutenant in the German army, by conscription, but a theoretical astronomer by profession,” as Mann puts it, heard of Einstein’s theory. He was the first person to work out a solution to Einstein’s equations, which showed that a singularity could form–and nothing, once it got too close, could move fast enough to escape a singularity’s pull.

Then, in 1939, physicists Rober Oppenheimer (of Manhattan Project fame, or infamy) and Hartland Snyder tried to find out whether a star could create Schwarzschild’s impossible-sounding object. They reasoned that given a big enough sphere of dust, gravity would cause the mass to collapse and form a singularity, which they showed with their calculations. But once World War II broke out, progress in this field stalled until the late 1950s, when people started trying to test Einstein’s theories again.

Physicist John Wheeler, thinking about the implications of a black hole, asked one of his grad students, Jacob Bekenstein, a question that stumped scientists in the late 1950s. As Mann paraphrased it: “What happens if you pour hot tea into a black hole?”
