For Tiny Light Particles, 'Before' and 'After' Mean Nothing

In this mini world, the concepts of "before" and "after" dissolve, such that two events can both precede and succeed each other. In other words, event A can occur before event B, and event B can occur before event A...

This idea, called a "quantum switch," was first proposed in 2009 by another team and has since been explored both theoretically and experimentally. Previous experiments showed event A could both precede and succeed event B, but the research couldn't say that these two scenarios were happening at the same place, said Cyril Branciard, co-author of this new study and a physicist at the NÉEL Institute in France.

To determine exactly where these violations of causality occurred, the researchers "implemented another quantum switch with a slightly different architecture," Branciard told Live Science. The new design allowed them to demonstrate experimentally that event A was happening both before and after event B not only at the same time, but also in the same place, Branciard told Live Science. Branciard and his team programmed and observed how a photon — a quantum particle of light — moved its way through a circuit. The photon could take one of two paths: If the photon took one path, they called the occurrence event A, and if it took the other, they called it event B.

A photon is can be thought of as both a particle and a wave. If the researchers used a photon with a horizontal polarization— the direction in which these waves oscillate— the photon would first travel path A and then travel backward to pass through path B, meaning event A happened before B. If they vertically polarized the photon, the photon would travel first through path B, then A, meaning B happened before A.

"At the end of the photons' journeys, the researchers could measure the new polarization."

Time is immaterial for light particles.

Causuality is not destroyed - depending on the polarity, A precedes B or B precedes A, depending on the polarity … now if Christine Ford decides to testify, all bets are off!

Yup.
A photon perceives itself as existing along its entire path, no matter how long that takes, simultaneously. There is no passage of time from the start to the end of its trip - even if it took a billion years. All at once, zero distance, from its perspective.

There has been a variation of the double slit experiment in which it appears that the path of the electrons changed AFTER they had already gone through the slit.

Or as the late, great Rick James said, “Cocaine is a helluva drug.”

Don't get confused, Ben. It can easily be explained by a series of basic equations:

Which simplifies to:

The simplest explanation is that they don’t have a clue and just make up stuff as they go along. Then rely on the old “If you don’t have a PhD you can’t understand it. You must bow down to our elitist “superior” knowledge that we pull out of our @sses.”

Before A can precede B, and vice versa, doesn’t it have to travel 186,000 miles first?

Anyone who really thinks that “Schrödinger’s cat” can be both alive and dead is not reasoning properly, and must remain silent.

Where this is going: the destruction of the principle of cause and effect.

Sorry, but alive = not dead, and the effect follows the cause. This is true no matter what some deluded scientist says.
