The Cheshire cat effect debunked.


"Recent studies challenge the quantum Cheshire cat effect’s initial interpretation, highlighting the role of contextuality in quantum mechanics. This research suggests that the perceived separation of particles and their properties is a result of how quantum systems are measured, not an actual physical phenomenon. Understanding this could unlock new insights into quantum mechanics and its applications.

The next part of the text means that the particle cannot leave or separate itself from its properties. But the particle can multiply its properties into another particle. And if the particle transfers its quantum field and quantum field's oscillation to another particle. The receiving particle's energy level rises so high level that it covers the original particle below its shine. 

The particle and its properties cannot separated from each other. And that means the Cheshire cat effect is not possible. 

The Cheshire cat-effect in quantum mechanics was a hypothesis that the particle can separated from its properties. But that thing was not possible. And the particle is always connected to its properties. 

In some models, superposition makes two identical particles. And if the energy level on the other side of the superposition steps to a far higher energy level than the other. In that model, the "shine" of the other particle covers the original particle. 

The model goes like this. First particle 1 makes superposition and entanglement with particle 2. The energy level of particle 2 turns higher than particle 1. That means the shine of particle 2 covers the particle 1. The reason why this superposition and entanglement must go like this is that explains why researchers cannot see differences in an "empty" quantum field. 

But when we think about the situation in which a particle seems to leave its properties behind it, we can think that the particle's quantum field is the thing, that we call properties. So the case should look like this. The particle disappears or changes its position. And then that particle leaves an "empty quantum field behind it". And the question is how this thing happens? 

Some other particles like quark or gluon may reach the same energy level as electrons. Quarks and gluons are far smaller than electrons. 

And if they get the same energy level or mass as electrons the electron's quantum field can make a superposition with that quantum field. The energy flow from the quark or gluon would be very strong. And that makes it very hard to detect and recognize the particle. If there is some kind of particle. The virtual particle can also have a quantum field. 

So how could researchers think during some tests particles separated from their properties? That is an interesting question. The particle leaves its position and leaves the quantum field behind it. That field acts like the particle's or particle-pairs original quantum field act. 

That thing might be some kind of virtual effect, where some particle made a superposition with some other, different types of particle, like an electron-quark pair.  Could that thing be possible? 

Theoretically electron can make a superposition with, as an example, the quark's quantum field in the case that the quark reaches the same energy level (mass) as an electron. 

So in this case, some particle that gets the same mass as the first particle can get superposition into its quantum field. The fascinating model is that theoretically is possible. That hypothetical graviton particle will reach the same energy level or mass as an electron. And that thing can form the "empty quantum field".

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.

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...
