It turns out that two particles can indeed collide with each other - provided they are completely identical to each other; Like identical twins indistinguishable
There is only one reality. That's what logic says. But the quantum theory, the most proven scientific theory, allows several contradictory realities to exist at the same time. For example, when photons (particles of light) are launched one after the other at a plate with two slits opened, and a photographic plate was placed behind it, logic says that the particles can pass through one slit, or the other. But, a series of light and dark spots is obtained on the photographic plate. The meaning of this phenomenon is that each of the particles passed through both cracks at the same time. The dark spots (where the light did not reach), are places where these two realities (or the two paths of the particle's existence) canceled each other out (a phenomenon called destructive entanglement). The bright spots are the places where the two realities reinforced each other (constructive interference).
As strange as it may sound, this experiment has been carried out in practice and has led to the same results many times over. Thus it became clear that the world of tiny particles, the quantum world, works in a very different way from the world of large objects, the world known to humans. This difference, between the two worlds, raised many questions. Where is the boundary line between the quantum world and the world we know? What happens when a whole molecule is sent towards the two cracks? Or a living cell? Or an intelligent creature? What happens when you try to find out, using a special detector, where each particle really went? Prof. Mordechai Highblom, Head of the Department of Condensed Matter Physics at the Weizmann Institute of Science, and the members of the research group he heads, investigate these phenomena and perform entanglement experiments of moving electrons in special devices made of semiconductor materials.
One of the central questions in this field of research is, does each particle stand on its own, and only interferes with itself, or is there also a quantum entanglement of two particles interfering with each other. It turns out that two particles can indeed collide with each other - provided they are completely identical to each other; Like identical twins indistinguishable.
Identical twins have a well-known advantage: other people can't tell them apart and therefore can't tell if they've switched. The members of Prof. Highblom's research group came to know that in the quantum reality, the abilities of identical twin particles take on a surprising meaning. Post-doctoral researcher Yizhar Neder, research student Nissim Ofek, together with Dr. Yunchol Chang, Dr. Diana Mehlo and Dr. Vladimir Umansky, launched pairs of electrons, from two different ends of a semiconductor device, to another the other ends of the device. The particles reached four detectors at the ends of the device (two at each end). In other words, each of the particles could "choose" one track from two possible tracks, and one detector from two detectors placed at the end of each track. In this way, the scientists wanted to check how the decision and choice of one particle affects the decision of the other twin, launched from the other end of the experimental device.
This is similar to the situation where two twins leave two houses, on their way to two different schools, located at opposite ends of the city. Each of them chooses to enter - in their school - one of two classes: A-1 or A-2. What is the probability that both will choose the same class? Attempts to answer this question are met with difficulty: it is impossible to know which twin went to which school. There are two possibilities: either the first twin went to the northern school, and the second to the southern, or they alternated with each other, and the first twin went to the southern school, and the second to the northern. According to quantum theory (as in the two-slit experiment) these two possibilities exist at the same time ("superposition"). The interplay of these two possibilities caused a surprising coordination between the decisions and choices of the electronic twins (which in the real world would have been manifested in the fact that the two twins who are distant from each other would always choose to enter the same class). But, the coordination between the twins was canceled when the researchers slightly changed the trajectory of one electron. That is, in this situation, the coordination was always reversed: if one chose to enter class A-1, the other always chose to enter class A-2. How does the other twin know that his twin brother has changed his course?
This situation in which the twins seem to be reading each other's thoughts from a distance is called the "entwined situation" and it was previously predicted by Albert Einstein, Boris Podolsky and Nathan Rosen in a joint article published in 1935. This is a situation in which it seems as if two systems are very far from each other, They are coordinated to such an extent that one "knows" immediately what is going on in the other system.
Experiments in entangled states were performed in the past, on particles that came from a common source. But in an experiment carried out by members of Prof. Hyblum's research group, the results of which were recently published in the scientific journal Nature, it became clear that entangled states are formed even when the two twin electrons came from completely different sources. Admittedly, it is impossible to know where each one ended up, but one can know for sure that they went completely separate ways, did not see each other, and did not speak to each other. In fact, they don't know each other at all, and yet, they "feel" each other from a distance - just because they are identical twins.
These findings contribute to deepening the understanding of the connection between quantum reality, the world of large objects and human beings.

As a principle, physics affects the quantum world and not the other way around.
So that there cannot be multiple realities.
Although it seems logical to think that the small will affect the large
but it is not correct.
So it doesn't matter if it's 6+1 or 3+4 or 2+5 the main thing is that the result is 7
Physics forces the quantum world to obey the principles of physics without actual intervention.
It's actually very interesting and the emphasis is on the intertwined states, it seems that the experiment sharpens the field, and in fact the next thing came out of that unclear area, if only from the understanding that nature indeed has such intelligences and more than that, that it even sounds logical - even in quantum terms.
It's a bit like going hunting in an unfamiliar area after it rained.
If it casts a shadow on us, on our perception or on our understanding of the mechanics in which things happen, then obviously the same suspicion about the 'knowledge' of the particles or in general, any type of system that has an awareness of physical damage or an 'intention to...' is a system that uses In tools and rules that indicate inventions of a general awareness (not related to size..) that is not so foreign to us. This is the same well-known feature, although it has no scientific basis and currently it is found 'only' among intellectuals and housewives, or alternatively, with the American spy agency (see their experiment in telepathy) but perhaps the answer is more complex there.
Let's say that if quantum theory is basically a combination of wave-particle states, then there is no logical obstacle to doing an experiment that combines spiritual and physical domains if there is a correct formula to do so, I say that like then, when everything was already impossible, the combination of a wave-particle was a kind of refuge Not 'kosher', a kind of compromise with surprising results, after all we got where we got with it today... There is not a single area in our lives today that is not intertwined in one way or another with the consequences of quantum theory, whether in science, whether in economics, etc.
In my opinion, even where we are today at this junction of the last decades, there is a principle or the same that does not make sense and combine the different types of concepts together.
What's a shame is that the science club is a club and anything that doesn't come with receipts of numbers or formulas is rejected outright.
Really tiny I must say... and it's a shame,
In my opinion, we haven't exhausted anything yet, and certainly as we live in a completely different reality than it was only one century ago, if these seem outdated to us, what will happen in a few generations?
It's time to broaden horizons and do things in new areas because as it seems today, we don't have much time or many choices left..
Someone asked here 'what's new?' And it's true, Ecclesiastes also said that there is nothing new under the sun, and I, a sage in the night like me, says that there is nothing new, but that was said by someone who ended up talking to bees, so everything is relative, and what was clear to King Solomon, is probably not clear to us.
One thing is certain, it definitely means that there is such a thing, and as a basic assumption it means that maybe we can use another system of understanding and execution that is intuitive and more than that - applicable. At least for particles.
Maybe we are on the verge of a discovery that will cause us such a change that will literally make all of life a completely different thing? who knows,
We want it fast and now, but nature has its own plans, it turns out, and he, too, in his awareness, does not hand over the keys to the ship so quickly.
I didn't delve that much, but the obvious question was asked:
If the two particles were completely identical, then how did the lab team manage to tell them apart...?
In addition, a well-known principle in quantum mechanics is that "what cannot be measured, does not exist" and according to this logic, she said the following: "There are two completely identical particles that we cannot distinguish between them" is an obscure statement because if I measure two particles then it is clear that they are not The sea is completely…
How does the experiment differ from the description in Gaziorovich's book (from memory and I may not be accurate in the small details, but I remember the principle very well) on those two particles that move towards each other, after they "collide" there is a 50% probability that they collided and each particle returns back or that 50% that they pass each other "through each other"
In short, is there anything new under the sun here?
A beautiful video on this very topic -

Nir's questions are correct and correct... but the scientists continue to test with the isolated method of two particles as if such a situation exists in nature!!
Indeed, the distance is of crucial importance and a millimeter is not the same as a million kilometers (let's leave out light years)..but the article is not flawed if the experiment is already flawed! Although it is not possible to know in advance what the result will be because for that purpose an experiment was conducted to reach a result..any !!
And in fact the same questions can be asked about normal particle experiments!! There, too, they "sell" us a censored story and neglect many parts of it that might contradict the official version!!
Infinite, yes, two, but I see no obstacle to more, the connection is not understood.
What is the range of influence of one particle on its twin?
Can one particle affect a twin particle located a million light years from us?
How many twin particles can there be?
And if all the twin particles affect each other, how could the experiment even be carried out?
It may sound strange but the article is extremely flawed
And sounds like astrology 🙂
