RESEARCHERS FROM FOUR UNIVERSITIES in Germany have conditioned a lab to register the coldest effective temperature in a research-controlled environment ever recorded-38 trillionths of a Kelvin above absolute zero. According to a 2021 study published in the journal Physical Review Letters, the temperature persisted for two seconds at the University of Bremen's Center of Applied Space Technology and Microgravity (ZARM), and the conditions that made this possible could have longstanding ramifications for quantum mechanics.
Absolute zero is 0 Kelvin, equal to -273.15 degrees Celsius, or -459.67 degrees Fahrenheit. This is the point at which particles are essentially motionless, and it's the lowest possible temperature we could ever theoretically reach, according to the laws of thermodynamics. Some researchers seek absolute zero for use in precision instruments that can test the fundamental laws of physics, while others do so to model something called the Cold Big Bang, when all matter exploded into being and the universe began operating under observable laws of matter and energy. In this latter sense, looking at a system at absolute zero-one almost completely without kinetic energy-would be close to observing the very beginning of physics.

Whether We Live in a Simulation - scientist Melvin Vopson, PhD, studies this exact thing- the possibility that the universe might indeed be a digital facsimile. And he claims to have evidence.
In the 1999 film the Matrix, Neo discovers A truth to end all truths-the universe is a simulation. While this premise provides fantastic sci-fi fodder, the idea isn't quite as relegated to the fiction section as one might expect. . In fact, University of Portsmouth scientist Melvin Vopson, PhD, studies this exact thing- the possibility that the universe might indeed be a digital facsimile. And he claims to have evidence.
The Ancient Language of Easter Island - Today, humans inhabit- or have, at the very least, explored- pretty much every corner of the planet. But that immense proliferation of Homo sapiens across the globe was a slow process.
With the first humans leaving Africa between 60,000 and 120,000 years ago, the species slowly spread across the Earth over many millennia. And one of the last places these ancient humans made their way to was the southeastern Pacific island of Rapa Nui, known more broadly as Easter Island.Located 2,360 miles off the coast of Chile, Rapa Nui is one of the most isolated places in the world. Its native people, who are also named the Rapa Nui, first arrived on the island's shores between A.D. 1150 and 1280, and lived in isolation until the arrival of Dutch navigator Jacob Roggeveen in 1722.
Underwater UFOs - A retired U.S. Navy admiral believes that the government should look to the oceans to help solve a mystery in the skies.
A retired U.S. Navy admiral believes that the government should look to the oceans to help solve a mystery in the skies. Rear Admiral Timothy Gallaudet, former Oceanographer of the U.S. Navy, recently published a paper arguing that unidentified anomalous phenomena (UAP, more commonly referred to as UFO) and unidentified submersible objects (USO) are linked, and should be studied further.
Synching Up Our Circadian Rhythms - If you've ever done any kind of long-distance travel, or just woken up feeling under-rested thanks to daylight saving time, you know how important your circadian clock is.
If you've ever done any kind of long-distance travel, or just woken up feeling under-rested thanks to daylight saving time, you know how important your circadian clock is. Like many things in your body, your circadian rhythm is more complicated than it might seem on the surface. Rather than being entirely brain-based, it's actually controlled by a collection of several circadian clocks (central and peripheral) that all work together to keep your gears turning like a well-oiled machine.
