  • Join Professor Jim Al-Khalili on an intriguing journey through the enigmatic realm of quantum physics, a scientific theory that has baffled and fascinated minds since the early 20th century. It all began with a seemingly innocuous question about the functioning of light bulbs, leading scientists on a profound exploration into the sub-atomic universe, where the ordinary rules of reality are flipped upside down.

      Lol. Wow. Truly all different kinds of people in this world, as opposed to a generalized "normal" which most would assume is the case.
      However, in actuality, instances like these make it clear & obvious that abnormal subspecies' are, indeed, amongst us and do, occasionally, present themselves.. most often by volunteering opinionated rhetoric, void of any real substance, yet displaying an incredibly dull mentality - which, undoubtedly, is woefully disengaged intellectuality, which we sometimes take for granted.. also evident is an irreconcilable disenchantment of reality when compared to the vibrant, mindful norm which we endlessly study, adore and tend to thrive in.
      Unfortunately, for this specific abnormal subspecies, the abnormalities are such that any concept of focus and/or attention span have literally devolved and regressed, almost entirely, down to the *thousandth decimal place* which has rendered all faculties inoperable, to a virtually non-existent state, leaving in it's wake a dramatically reduced mentality, resulting in a complete inability to reason, analyze or interpret even the most minute of observations.
      This severely compromises the individual's ability to gather the necessary material required in order to think critically or form sustainable hypotheses for future studies. Therefore, vacated is the right to compile data needed to form the eventual theory, also vacated is the ability to form a meer opinion on any given subject, despite the level of importance, or significance.
      This is a great example of just how reduced the individual will inevitably become, after an incomprehensible regression into a single point, void of meaning, only capable of contributing impulsive linguistic patterns which are spewed into existence and onto the faces of the intellectual, sophisticated, scholarly noblemen.

    @40:00 For those interested, the Helium "problem" refers to stars early in the age of the universe with only about 1/3 of the helium expected, helium being produced by fusion within stars of hydrogen. Measurements showed more carbon, nitrogen, and oxygen in the stars than expected, which leaves open this question of where did all the helium, one of the most abundant elements in the observable universe, come from? As this measurement of helium came from a small sample of stars it could simply be an anomaly, or if actually representative it could suggest that there was some kind of secondary fusion taking place outside of the stars converting hydrogen to helium. I'm not an expert but I believe that these days the more common belief is that how much of a particular element stars produce is based upon their characteristics like their mass.

      His honesty isn't good enough for you? You are right, of course. Our understanding (given materialistic assumptions about the nature of ALL reality) breaks down.
      Case in point, Einstein said, "I'd like to think the moon is there when I'm not looking at it".
      Einstein's intuition was correct. There is a deterministic aspect to reality that makes it objective to you and I. Our observations and measurements, however potent they are, do not define EVERYTHING.
      But this does not mean that everything is determined mechanistically. Conscious agency can also determine and define (measure), according to purposes independent of material causality.
      You are fooling many with your assurances (look at all those thumbs up). But not I.

    I've seen all the laws broken here on Earth: time, motion, potential energy, kinetic energy, gravity, all of it. I watched time stop for all objects except me, same for gravity and motion. A clump of dirt flew in and was frozen in front of me. I also forgot that I was in the middle of a car accident and the car was in the air as well as we hit an embankment at 85 mph. All I cared about was what this thing was that flew in the car. It looked like dirt but dirt doesn't fly and stop. I had to scoot up to see it better. I still couldn't see it so I had to loosen my seatbelt to scoot all the way up. I put my eyeball right next to it and saw that it was a clump of dirt. Then I remembered about the car accident and had a quick panic attack. I checked my seatbelt and looked at my friend. His face was frozen just like the sand. I saw his seatbelt on, then boom. Time came back on. My friend didn't have it happen to him.
    It was like pushing pause on our environment including my friend; pausing everything except me. I stayed in normal time, gravity still worked for me as I wasn't floating. The sand looked still floating in the air. I figure that it took about 15-20 seconds to scoot up, then again, then freak out, finally check our seatbelts. It wasn't an adrenalin rush like everyone says. I was completely calm and normal until I remembered what was happening and realized that time was stopped. Then I freaked out, but before that I was normal.
    That is one of like 25 stories that happened to me. When I was ten years old, it happened in front of my parents. I was doing my homework and the phone started ringing. I looked at my dad and he didn't move at all. Looked at my mom, the same. I get up kind of upset nobody was getting the phone when I was trying to do my homework. My dad looked at me like WTF and my mom got up from the other conjoined room to see what I was talking about. When I got to the phone and was reaching for it, it rang for real. The two rings overlapped each other causing a much louder ring. I was instantly sick and going to faint, but my mom caught me by my cheeks and told me I had a gift of ESP. I slept for a day and a half. There's two. This life is an illusion, a simulation. I know that's hard to believe unless what happened to me happened to you, then after thinking about it for 30 years, you would have the same conclusion as I have had. It has to be a simulation. All of you are simulated.
    Why am I writing this then if you already know that? I guess for the chance that someone may know how to get out of the simulation. The exit.....

    I think its very interesting that the electron produces the same pattern as a photon because it has charge. If we say that the electron is in a superposition before interacting with the detector, cancelling out in areas of desrructive interference, the question arises whether charge would play a roll. But it clearly doesnt. The wave function does not account for the particle's own charge, but the charge of other particles. How is this distinguished? And ill point out that photons can exist in the same exact state as bosons are exempt from the exclusion principle. So its not as if it is somehow bouncing off itself in a state of superposition. This is truly bizarre and unique.

    This is just the explanation about quantum mechanics I was waiting for in years. Thank you for that Professor Al-Khalili. In my understanding Physics is aimed at associating models (numbers and equations) to the real things. Models are there to predict the result of future experiments, which then prove if they were right (aka: applicable) or wrong. So I have no problem if a (relatively) free standing electron, or a crashing electron on a detector follows the particle model, while a fast traveling electron fired by the gun follows the probabilistic wave model. What I miss in this case is a description of how properties of the electron are modified when it is "fired" (or: what makes it "evaporate" to a probabilistic wave). Similarly, how the electron properties are modified when it is "detected", "measured" or when the probabilistic wave "crashes" on some obstacle to crystallize again as a particle at a (somewhat predictable) random place in space. Studying these transitions could be more profitable than arguing on "which reality is real". Concerning entanglement, did someone look at it as two crystallization's of a single wave ? The video suggests that the second coin continues to turn when the first one is fixed. Isn't that misleading ? when the first one is "detected", what if the second one has been displaced out of reach of a detector ?

      But what an admission to make, that" QM defies logic".. In other words, its not rational. In even more words, that means that it cant be studied by rational logic humans, who's only way of discovery is by applying the rules of logic together with a rational understanding. So maybe we should let patients on mental hospitals study QM? because they are irrational and illogical? And their thinking can not be understood by those that are rational and logical. But maybe scientists ought to reconsider their interpretation of those few observations that led up to the belief that there was a new science at work, namely QM. Its more likely that they are flat out wrong. But too pig headed to admit that they have been fools. Another bit of "science " that is irrational and illogical in everything that Einsteins said. Few people have realized this fact thought. Meantime is a great article of faith for the believers.

Not getting bought it becomes minced meat getting a new date. Not getting bought it becomes sausages and a new date. Not getting bought it could become a part of a pre made dinner only needing a little heat to be eaten. Not getting sold it doesn't get a new date but a considerable discount. Someone is almost bound to buy it. Thinking it was only made yesterday - if I eat it today it will be safe and almost as good as new.

As try as I can, however, I still do not understand why it is that Bell's experiment showing sums less than or greater than two answers the question whether Planck or Einstein was right in explaining the uncertainty about entanglement and whether there is spooky action at a distance or some hidden variable that underlies and explains entanglement. Is there a chance you could explain why knowing the answer to be < or > 2 is outcome determinative?

      @@Bill_Garthright I can't say you're wrong because I don't know for sure, but I just looked up "spooky action at a distance origins", and found references only to Albert Eintein having coined it. I also searched for any refernce to Newton in the phrase, but all I found was that Newton said that gravity caused "Action at a distance", with reference to the earth/moon attraction - but no indication that Newton thought it "spooky".
      Incidentally (fun fact), Newton declared that he saw further, because he stood upon the shoulders of giants (a rare moment of humulity from what I can gather). When Einstein was asked by a reporter if he stood upon the shoulders of Isaac Newton, he replied "No. I stand upon the shoulders of James Klerk Maxwell". However, I did find an Einstein quote about Newton : ""Newton, forgive me," wrote Einstein; "you found the only way which, in your age, was just barely possible for a man with the highest powers of thought and creativity. The concepts which you created are guiding our thinking in physics even today..." And, of course, he used calculus - though Leibniz should probably get the credit for the calculus we use today.

Assuming the electrons are entangled, how did that happen and still guarantee they ended up in the correct positions?

    Time is fascinating. I worked the subway stations for nearly 10 years. From one end of the city to the other. Every so often I would notice the city would be saying that, "Today just flew by" or "The day was just dragging along." How can an entire city, with no interaction with each other until they used the subway, complain about the same time paradox unless it was effected by it? Maybe a time distorted bubble the earth passes through in its revolution around the sun. Maybe random waves of time distortion hitting the earth? Maybe they're given off by the sun. Maybe they're from outside our Terran system and reach us in intervals. ???? 🎶Ti-i-i-ime, is on my side. Yes, it is!🎶
    If you can think of a better way to do a blind survey of an entire city, in the small window of opportunity, I'm all in. Until then, I invite you to spend a couple years in the subways. Between 2pm-10pm and you'll see for yourself. Just listen as an entire city gets off of work and gets out of school. You'll see it's more than a, "coincidence of circumstances."

      Anything involving faith and beliefs is involving a god or gods. Science isn't absolute either. You can study doing experiments making a theory plausible. There are many levels of scientific proof. It can relate to a very specific subject under specific circumstances. It could be applied in a wider context being a general law/theory but not being specific. In fact it could be any combination thereof. Theories are more often than not a working model applying the knowledge in a way that brings understanding - but not entirely correct. Engineering is science put to practical use... cutting corners - things have to be safe and working. You add a little here and there to ensure things are safe and working properly in a given interval of time.
      Some scientist believe in God but see no conflict. As scientist they speak upon matters they can prove or make plausible. Religion is another dimension. Copernicus discovered the Heliocentric System. The sun being the middle of the Universe and everything else being in orbit around the sun. He himself was a devoted believer. He saw it as a form of worship understanding the inner workings of Gods creation. Adam and Eve took a bite of the Apple of Wisdom - why they were kicked out of Eden. Having knowledge they now had to use their intelligence to make a living. Just like young people graduating moving away from home. As far as I know most religions encourage getting knowledge (both sexes). All major religions have it including Islam. Traditions and cults derived from the original scripts may have other rules - but they're not found in the "original" religion/scripts. Adam and Eve were basically told to use their brains. People using religion to debunk science are just as wrong as people trying to debunk religion with science. To different systems you can't apply rules from one to the other. The simple saying of comparing apples to oranges. They're fundamentally different. You can't compare. The measuring sticks are different as well.

    I am ignorant of sciences, but curious and always inquiring about some of the regular situations in my everyday routines. In this video, my doubts have increased, and I am more skeptical about whether I exist or if it is just being a part of something undefined, uncertain, and surreal. How knows!
