The researchers point out that in the micro-world of atoms and particles. Which are subject to the strange rules of quantum mechanics two different observers entitled to their facts. Now the new experiment suggest Objective reality may not exist.
In other words, according to our best theory about the building blocks of nature itself, the facts can be subjective.
Observers are powerful actors in the quantum world. , particles can be in many locations or various conditions. This called an overlay. But it is strange that this only happens if they ignored it.
When you look at a quantum system, it selects a specific location or country that violates the overlay.
This behavior has demonstrated many times in laboratories, for example in the famous double-slit experiment.
In 1961, the physicist asked what would happen if quantum mechanics applied to an observer he observed himself. Imagine being a friend of Wigner’s, tossing a quantum coin in a closed laboratory, head covering and head.
Every time a friend tosses a coin, he observes a certain result. We can say that Wigner’s friend knew that the coin toss must have been ahead or a tail.
Wigner did not have access to it from the outside, and according to quantum mechanics, he had to draw his friends and coins to superimpose all possible experimental results.
This is because they related to ghosts with each other. So if you manipulate one, manipulate the other.
Now, Wigner can generally examine this stretch with what called a “quantum-interference-measurement experiment”. which allows you to guess the superposition of the entire system and confirm that the two objects interrelated.
If Wigner and his friend then compare notes, the friend insists that he has seen certain results for each coin toss. But, Wigner will not agree every time he sees a friend and a coin in an overlay.
That’s a puzzle. The reality felt by a friend cannot be reconciled with external reality. Wigner did not consider this a paradox but argued that it would not make sense to refer to the conscious observer as a quantum object.
Physicist John Bell in 1964. Bruckner saw two pairs of wigs and friends in two separate boxes and measured the general condition inside and outside the box.
The results can be summarized and finally used to test what called “Bell inequality”. If this inequality violated, observers may have alternative facts.
Experiments provide clear results. It turns out that both realities can exist at the same time, even though they produce inconsistent results, as predicted by Wigner.
This raises some interesting questions that force physicists to reconsider the nature of reality.
The idea that observers can reconcile their measurements with fundamental reality based on several assumptions. The first is that universal facts do exist and which observers can agree on.
But there are other assumptions. For one thing, observers have the freedom to make all kinds of observations. And the other is that the decision made by the observer has nothing to do with choice, while other observers assume that physicists call the field.
If there is an aim reality that everyone can agree on, then all these assumptions are correct.
But, the results show that there is no aim in reality. In other words, experiments show that one or more assumptions are the idea that there is a reality that we can agree on, the idea that we have freedom of choice, or the idea of a place must be wrong.
Of course, there are other solutions for those who follow the conventional view of reality. This is that other gaps ignored by researchers. Indeed, physicists have tried for years to close the door in such experiments even though they admit that it will never be possible to close everything.
These are all deep philosophical questions about the nature of reality. Whatever the answer, an interesting future expected.
