Physicists Demonstrate How to Reverse of the Arrow of Time

Posted by in category: physics

Circa 2017

One of the more curious challenges in physics is to understand the nature of time. At the microscopic level, the laws of physics are symmetric with respect to time—they work just as well whether time runs forwards or backwards. But at the macroscopic level, processes all have a preferred direction. The great physicist Arthur Eddington called this the “arrow of time.”

Just why this arrow points in one direction but not the other is one of the great scientific puzzles. The standard answer is that the arrow of time follows from the Second Law of Thermodynamics—that disorder, or entropy, always increases in a closed system.

Looking Back on The First-Ever Photo of Quantum Entanglement

Posted by in categories: computing, particle physics, quantum physics


This stunning image captured last year by physicists at the University of Glasgow in Scotland is the first-ever photo of quantum entanglement — a phenomenon so strange, physicist Albert Einstein famously described it as ‘spooky action at a distance’.

It might not look like much, but just stop and think about it for a second: this fuzzy grey image was the first time we’d seen the particle interaction that underpins the strange science of quantum mechanics and forms the basis of quantum computing.

Quantum mechanics in the brain

Planet Earth Report –“The Age of Pandemics to MEGA Thruster Taps into Fabric of the Universe”

Posted by in categories: biotech/medical, space travel

“Planet Earth Report” provides descriptive links to headline news by leading science journalists about the extraordinary discoveries, technology, people, and events changing our knowledge of Planet Earth and the future of the human species.

The Universe Might Be Too Thin, Scientists may have found a new crack in our understanding of the universe, reports The Atlantic and Quanta. The cosmos is starting to look a bit weird. For a few years now, cosmologists have been troubled by a discrepancy in how fast the universe is expanding. They know how fast it should be going, based on ancient light from the early universe, but apparently the modern universe has picked up too much speed—a clue that scientists might have overlooked one of the universe’s fundamental ingredients, or some aspect of how those ingredients stir together.

The Army wants to build a brand new exoskeleton to help soldiers ruck faster and harder

Posted by in categories: cyborgs, robotics/AI

The Army is formally moving ahead with the development and fielding of a powered exoskeleton to help soldiers move faster and carry more while reducing overall fatigue after years of experimentation and testing.

Officials with Army Futures Command are currently in the process of drafting formal requirements for an infantry exoskeleton ahead of a defense industry day sometime in November, said Ted Maciuba, deputy director of the robotic requirements division for Army Futures Command.

Breaking Defense first reported news of the fresh exoskeleton effort.

Like Concrete

In simpler terms: the resulting material “feels like concrete but much lighter,” Fernandez told CNN. “Very light rock.”

“We have a route to… manufacturing buildings to tools from 3D printing to mold casting with just one single material,” he added.
