Researchers at Aalto-University created Alice's ring for the first time.

 Researchers at Aalto-University created Alice's ring for the first time. 


Researchers used quantum gas which temperature turned into an extremely low level. And then they pressed those very cold atoms, which temperature is at least near zero kelvin degrees into one point by using magnetic fields. That is called Bose-Einstein condensate. And in that condition, the gas atoms are starting to act like one big atom. In that case, the electrons transfer into the outer shell of that entirety. 

Or otherwise said, electrons start to orbit those atoms as if they are one atom. And that thing helps to form a magnetic monopole. In a magnetic monopole is only a plus or minus pole. When researchers remove an outcoming magnetic field, magnetic repelling pushes those particles out of the form.

Also, an extremely strong gravity field can keep a magnetic monopole in its form. And that causes a question Are the hypothetical quark stars or black holes magnetic monopoles? 


Monopolar objects require a strong electromagnetic field that pushes them inside and keeps the particles in form. Another thing that can create stable magnetic monopoles is gravity. If the gravity field is strong enough, that thing makes it possible to form a stable magnetic monopole. And that causes an idea about black holes. Are they magnetic monopoles? 

Magnetic monopoles can created by using protons, and electrons. The magnetic fields push those particles into the shape of a ball. Also is possible that neutrons whose poles (like N-pole) are turned radially from the center of the ball to the ball's shell can form magnetic monopoles. In that model, the N-poles or S-poles are making structures that look like thorns. And the neutron ball is covered with N- or S-poles. 

If there is only as an example S-poles that make the neutron ball monopolar. In normal situations, the neutron ball where neutrons are on the same side from in to out the electromagnetic repel force will destroy the structure. But if there are lots of neutrons gravity wins the electromagnetic forces. That thing causes a question: Is a black hole some kind of monopolar object? 

The Alice ring means that a magnetic monopole turns a whirl-like quantum structure. That thing is one of the most interesting things in magnetic monopole research. Alice ring is one thing that can be used to model virtual particles and the Swinger effect. The Alice ring introduces how particles are turning into wave movement. And mirror reaction is, of course, when wave movement turns into particles.

Researchers think that the multiverse is not fiction anymore.

Multiverse means that our universe is one of many universes. The reason why researchers and scientists believe that this is true is that logical. About 50 years ago people didn't know that there were other solar systems. Exoplanets were only theories in the 80's.  About 400 years ago people thought that our Sun was the only star in the universe. Edvin Hubble proved that our galaxy, Milky Way is one of many galaxies. Then researchers found that galaxies form groups, and supergroups. That means that today we think that the universe, where we live is the ultimate supergroup of galactic supergroups. And logically thinking there should be other universes. We believe that the universe began its existence in an event or series of events called the Big Bang. That event did not begin, because the energy that formed material should come from somewhere. The Big Bang was not one "bang" or explosion. It was a series of events where material took form. Or the energy level that it h...

Spinning cylinders prove a 50-year-old physics problem.

"Scientists at the University of Southampton have experimentally proven the Zel’dovich effect by amplifying electromagnetic waves using a spinning metal cylinder, confirming a theoretical prediction from the 1970s and opening new avenues in technology and quantum physics. Credit: SciTechDaily.com" (ScitechDaily, 50-Year-Old Physics Theory Proven for the First Time With Electromagnetic Waves) "“Colleagues and I successfully tested this theory in sound waves a few years ago, but until this most recent experiment, it hadn’t been proven with electromagnetic waves. Using relatively simple equipment – a resonant circuit interacting with a spinning metal cylinder – and by creating the specific conditions required, we have now been able to do this.” (ScitechDaily, 50-Year-Old Physics Theory Proven for the First Time With Electromagnetic Waves) Researchers amplified electromagnetic waves using spinning metal cylinders.

What makes it hard to create a room-temperature superconductor?

"The discovery of wave-like Cooper pairs in Kagome metals introduces a new era in superconductivity research, offering potential for innovative quantum devices and superconducting electronics, driven by theoretical predictions and recent experimental validations. Credit: SciTechDaily.com" (ScitechDaily, Kagome Metals Unlocked: A New Dimension of Superconductivity) "Superconductivity is a set of physical properties observed in superconductors: materials where electrical resistance vanishes and magnetic fields are expelled from the material. Unlike an ordinary metallic conductor, whose resistance decreases gradually as its temperature is lowered, even down to near absolute zero, a superconductor has a characteristic critical temperature below which the resistance drops abruptly to zero. An electric current through a loop of superconducting wire can persist indefinitely with no power source" (Wikipedia, Superconductivity) Theoretically, a superconducting electric circu...
