Scientists Finally Prove Strange Quantum Physics Idea Einstein Hated

Posted by in categories: information science, mathematics, particle physics, quantum physics, space

The equations of physics are things that we humans created to understand the Universe, and it can be hard to disentangle them from the Universe’s innate properties. It turns out that one of the weirdest things scientists have come up with, what Albert Einstein derisively called “spooky action at a distance,” is more than just math: It’s a fact of reality.

That concept is also known as entanglement, and it’s what allows particles that have once interacted to share a connection regardless of the separation between them. A team of physicists in the United Kingdom used some dense mathematics to come to their Einstein-angering conclusion, taking an important step towards proving whether quantum mechanics’ weirdness is just the math talking, or whether it speaks to innate physical requirements. Their mathematical proof’s main assumption is that any new physics theory should be backward-compatible with the physics you learned in high school.

New Recipe For Heating Nuclear Fusion Plasma Boosts Ion Energy Output 10 Times

Posted by in categories: nuclear energy, particle physics

Extracting useful amounts of energy from the merging of atoms is tricky business, not least thanks to the challenges of controlling squirming clouds of ultra-hot plasma.

Our clean power fusion goals could be a step closer now researchers have tweaked their fusion recipe to add a new ion to the mix. This allows researchers to get a better grip on how high-energy charged particles move not just inside reactors on Earth, but potentially provide insights into how they behave in stars.

A team of researchers at MIT have used data from experiments conducted on a type of fusion reactor called a tokamak to explore how adding a third ion to the more traditional two-ion plasma mix shakes things up.

Amat Farm

Posted by in categories: finance, particle physics, solar power, space, sustainability

Amat farms (antimatter farms) consist of large banks of solar power collectors which power multicolliders optimally designed to produce antiparticles. The vast showers of collision products which result are sorted magnetically; antimatter particles and other useful species are collected, cooled and held in electric/magnetic traps.

The first amat farms were established in 332 orbiting Sol just outside the orbit of Mercury, known collectively as the Circumsol ring. Several power corporations were involved in this effort, including the Look Outwards Combine, Jerusalem Macrotech and General Dynamics Corporation. In 524 the Jerusalem Macrotech station B4 was destroyed during an unsuccessful raid by Space Cowboys.

Amat fields designed to produce anti-protons are typically 100km or more in diameter; fields which produce positrons are considerably smaller. The antiprotons and positrons are usually combined into anti-hydrogen and frozen for easier storage.

Quantum Weirdness Has Been Tested Beyond The Particle Scale For The First Time

Posted by in categories: particle physics, quantum physics

A small tweak on a definitive experiment in quantum physics has allowed scientists to observe for the first time exactly how molecules behave as waves.

The results are solidly in line with what theory covering complex quantum phenomena predicts, so don’t expect any radical new physics here. But as with most quantum experiments, the implications of seeing such a counter-intuitive theory in action makes our head spin.

Researchers from the Universities of Vienna and Tel Aviv have recently collaborated on turning a two-decade old idea into a reality, replacing tiny particles with large organic molecules in a variation on Clinton Davisson and Lester Germer’s classic 1927 double slit experiment in order to test the limits of a law governing their behaviour.

An Accidental Discovery Shows Artificial Atoms Can Quickly Self-Assemble

Posted by in categories: materials, particle physics

Scientists have observed that superlattices can form incredibly during the routine synthesis of nanocrystals. This accidental discovery will mean the ability to form novel materials in a matter of seconds instead of days.

Some of the tiniest crystals in the world can, together, form superlattices, the basic elements of various novel materials. These crystals are also called “artificial atoms,” because they can organize themselves into structures that look a lot like molecules.

Scientists discover all quantum particles can travel BACKWARD

Posted by in categories: particle physics, quantum physics

In the study, researchers from the Universities of York, Munich, and Cardiff explored the phenomenon known as backflow in particles that are not ‘free.’

Free quantum particles exist without any external forces, but the researchers note that this setting is idealized.
