I once attended a lecture on consciousness by a well known professor whose name I've unfortunately forgotten. He never defined the subject of his lecture, but it became apparent that his implicit definition was: 'consciousness is what neurons do'. Unsurprisingly he concluded that nematode worms are 'somewhat conscious' while machines can never be conscious! When asked for evidence of nematode consciousness he produced a microscope slide of a dissected worm and declared 'look - neurons'! All sides of this debate are indulging in pseudo-scientific hand-waving until there is a mutually agreed definition of consciousness independent of any theory of how it works or arises.

[@bret44]

I agree, so many people turned their nose up at the alpha result but it was a beautiful experiment and had to be done. Most (not all) reasons that people normally give as to why antimatter should fall down, were actually not correct. I believe Aegis countered most of the arguments in their first paper and there is a wikipedia page too I think. It would have been an amazing revolution in physics had it fallen up. I still think they should do more work to make sure that the result fits more squarely over g and not just barely covers it with error bars (wasn't it like 7.5 +- 2.5).

[@kretieg]

Yeah. There doesn't appear to be an anti-higgs field. The experiment shows that the anti-matter is interacting with the same higgs field as normal matter.

[@ronald3836]

Some years ago after watching too many KZbin videos the question whether antimatter would fall upwards or downwards occurred to me. I am happy it has been answered now 🙂

[@WestOfEarth]

For the antimatter antigravity experiment, I was under the impression that the team measured the number of antihydrogen atoms that fell and compared it to the control experiment which measured the number of hydrogen atoms that fell. These percentages were nearly equivalent. If the number of antihydrogen particles that fell was less, it would indicate antigravity. They didn't actually measure the speed of the falling particles. Anyway, a null result is a valuable result.

[@EstamosDe]

Should they try with antimolecules ? I think it was not a 50/50 btw, it was 3/4 vs 1/4, and most of them went by the lower side. If they were 50/50 that might indicate they are indiferent to gravity, and that wasnt the result but gravity affects them. If they went by the upper side, they would have been affected by antigravity, I think (and I have questions about that, is antigravity suppossed to be, for this experiment in the case it resulted, antimatter being repeled by normal gravity created by normal matter?). I MIGHT BE WRONG, but I was listening to this experiment I think in Anton Petrov's channel. Edit: yes, he talked about this yesterday

[@wellesmorgado4797]

@@EstamosDe It is hard to make them. The anti-H atoms are seemingly too hot to combine into H2. I am not aware if they have been trying to cool the anti-H atoms along the experiment. Maybe Sabine can shed some light on it.

[@WestOfEarth]

@@EstamosDe yeah it wasn't exactly 50/50, but really close. Enough to warrant more experiments to see if the difference is real or due to experimental uncertainty.

[@crazedvidmaker]

I work on this experiment. You're correct that the speed of falling particles was not measured, but rather the number that fell vs rose. For the non-biased magnetic field, 94.5 fell down and 36.7 fell up. That is after subtracting a background in the detector due to cosmic rays, which is why it's a decimal. That's 72% falling down, and many sigma from 50%. And the antihydrogen isn't too hot to combine into H2, but first it's not even close to dense enough, and second, the groundstate of the H2 molecule doesn't have a magnetic moment, so H2 wouldn't be trapped in the magnetic minimum trap like H is.

Co-60 is a bit of a tall order, but you'd think H-3 might be possible?

[@crazedvidmaker]

@@zbret antimatter versions of He3, tritium, and a small handful of He4 nuclei have been observe in LHC collisions. But each additional proton/neutron adds a factor of roughly 1/1000 to the production rate. So if CERN was delivering tritium nuclei instead of antiprotons to the antimatter experiments, the beam would have about a million times fewer particles (10 instead of 10 million per minute) and it would take a million times longer to collect the same statistics.

[@av8r195]

honestly. i'm on board with labeling any theory of consciousness pseudo science, because as of yet, we've got no clue how to even determine whether something is conscious or not much less know what it is & how it occurs, the problem is, consciousness is a very subjective thing. only you can be sure that you're conscious. thus making objective scientific theories for it would be very hard. unless we can figure out a way to test whether something is truly conscious. we have no theory of consciousness, and thats the problem.

Dear Sabine, I want to congratulate you for the outstanding quality, clarity, and humor of your videos - great job! Please keep up the excellent work. On another note, I find myself aligned with Daniel Dennett's perspective in opposition to David Chalmers (and yourself) when it comes to Integrated Information Theory (IIT) being considered "pseudoscience." This viewpoint arises from the fact that it's increasingly challenging to differentiate pseudoscience from IIT, especially considering the groundwork laid by Scott Aaronson and others in this field. Their work has made it difficult to distinguish the consciousness stemming from IIT from other forms of consciousness. In fact, I do appreciate the "pseudoscience" label, as it might incentivize proponents of IIT to strive harder to gain acceptance. In a way, I see David Chalmers' comment as akin to a "Woke-defensive comment" within the realm of science. Once again, thank you for your fantastic content. Warm regards, Antonio from Mexico City 🇲🇽

[@Linguae_Music]

The mind is an emergent phenomena that arises from the hierarchical interactions that take place in the brain, It exists because the consciousness is smeared across time. The "present moment" is actually about 100ms long, You can consider this like having a huge slew rate - or, a huge lag. This is a significantly huge amount of time compared to the amount of time it takes for individual interactions to take in the brain. This would lead to systems having informational feedback, that would cycle within the time window of the present moment. Which would be a good condition for emergence to happen. As Information processing spreads across time, it also spreads across the system, and each moment of the awareness is looking backwards at itself, in this sort of self re-iterating cycle the marches forward temporally. Then, the information that the brain is getting from itself, leads to a self-modulating, guided rerouting of pathways. And this leads to the sense that really matters, the ability to sense the self. I think the ability to sense the self is a sense just like vision or smell... except there is no external receptor for it... it arises from the cycle of feedback and self-modulation, that just goes on forever until you die. :D Unfortunately it leads to this sort of conundrum of awareness. And that's brains! That's what the mushrooms told me. Usually what they say is half true and half lie... so I'm probably half right.

How to get the unpopped kernels out of your microwaved popcorn: When you take the bag out of the microwave, do not open it all the way, only open it wide enough for the kernals to fit out, but not the popped corn. Shake the bag with the hole down, probably over your popcorn bowl, but over the trash if you're daring. Wiggle it back and forth and shake it for a good 30 seconds or more. The kernals should readily work their way to the bottom of the bag and out the hole. This is not a perfect method, but you'll separate ~90% of the kernels out with minimal effort. Cheers!

[@christopherleubner6633]

To get attoseccond pulsed laser light, take a femptosecond laser and shine it through a cell that has a high non-linear coefficient, hydrogen or methane work well. Then take the output and use negative dispersion mirrors to stack the modes on top of one another. It shortens the femptosecond pulse into attoseconds. It is usually a diode pumped Ti:sapphire laser sent through crystals that make UV then use the UV to pump a wide band optical parametric oscillator and use a special mirror to cause the frequencies to stack on one another.❤

Hey Sabine, I'm loving taking the Quizwithit's quizes, they're super fun! I couldn't check the quiz's answer even though I signed up, though. Also, the background color for when you select an option by clicking on its button is too similar to its unselected version, you might want to increase contrast a bit. If I might make another suggestion, after I submit my answer, it takes a while for the quiz to move to the next question.

The only reason to think antimatter would exhibit antigravity is that they both have "anti" in their name. We would have been spared this concern had it been called "conjugate matter". edit: still, it's a good experiment

[@Cythil]

Calling it anti was not the worst move, however. A lot of stuff has worse names. The only thing is as a problem is that it makes regular matter seems like it the normal matter. It sort of is since that is what we come in to contact the most. But as far as we know, there is nothing fundamental different between matter and antimatter. There just two kinds of matter that happen to annihilate each other when in contact with each other. And as far as we know, one kind just happened to dominate our universe. (And while some see this as an odd that one is dominated, we should also remember the anthropic principle. It may be that in a thought of random chance we ended up in the universe where matter dominates. And we would not be able to exist in a universe where one did not dominate, since that universe would be pretty much empty of matter. And if we were in the antimatter dominated one, we should see the exact same thing. Why, I do not see this as a problem in itself.)

[@jormam69]

does it exhibit conjugate gravity though?

Does that make normal matter "uncle-matter" this is the real question.

to the consciousness thing: If I connect my nerves to a plant, I can feel the pain of the plant, but it needs a brain to feel it, so something needs a brain to store and experience the pain. When we die we forget about the pain we experienced, because the brain that stored the experience which is also able to remember that experience is no longer around to remember that pain. If we had 0 memory and experienced pain, we do suffer during the pain, but instantly after it happened we won't because we already forgot about the pain has happened, so if we look at consciousness from an outside perspective, it seems simple to understand it. Yet I have to admit, it does feel strangely alive to be just neurons communicating, but maybe that's just all it takes to feel that way

I think GWT would be better served in their criticism of IIT if they dropped the theatre analogy. At least in its summary, it is too reminiscent of the Cartesian theater, I think therefore... My take, if anyone cares 🙂 is that IIT is the right start but consciousness is emergent only after a certain point. Consciousness isn't a thing, it's a collection of things that reaches critical mass into consciousness. Pardon the "critical mass" in this context...

[@PrivateSi]

Certainly a deserved prize, just for the switch speed alone. Very useful. In the Electro-Positronic Field Theory (that only exists in my imagination) 2 positrons need to be precisely fired at 1 electron, with attosecond precision, from opposite directions at the same speed... If this forms a Proton I am right and Protons are made from from 2 positrons and 1 electron.. There is a chance this Strong Reaction can only happen under extreme conditions, perhaps only during a Big Bang, but my instinct says it's still possible... -- In my model new matter creation expands the field a tiny bit. Matter continuously being created would accelerate universe expansion. In the beginning 2 positrons collided with 1 electron to from a proton + left over electron more often than 2 electrons hit a positron to form an anti-proton + left over positron, so there are equal numbers of electrons and positrons but we have a matter, not antimatter universe. It is funny that there's exactly equal numbers of matter and antimatter elementary particles yet it's a matter universe, when it could easily have been an antimatter one. Just a slight bias in the REACTION SYMMETRY, which is acceptable and to be expected (else there'd be no matter or antimatter).

My first thought is that if your reaction works then it should also work in reverse. If a heavier particle can decay into lighter ones then it will. But the Proton is very stable and we do not detect decays. For the sake of discussion, there would have to be something preventing the reverse process. For example, free Neutrons decay quickly into slightly lighter Protons, and other particles to keep everything balanced. Neutrons are much more stable when in atomic nuclei. But Protons are stable in all circumstances. Offhand, I cannot think of anything to prevent the reverse process.

@@EinsteinsHair.. Yes, you may be right... Stars may produce a small amount of new matter throughout their lifetime, which adds up. It takes the core of a black hole to squeeze a neutron to annihilation, back to balanced=empty field in the model. A neutron being a Proton + neutralising electron (basically hydrogen that was squeezed into an atom).. Beta- radiation is a Neutron losing its electron, turning back into a proton. Beta+ is a new electron+positron pair formed near a proton with the positron expelled and electron retained... Neutron electrons bond to protons (2 protons share 1 or more electrons in atoms... and there's quantum gravity..). -- A Neutrino is a field cell displacement wave - a cell moves 1 to 3 cells (or 0.5 to 1.5 in half steps) before stopping. A direct subatomic particle hit transfers this 'Weak Force'.. -- In this Dirac Sea if a cell moves more than this it has Full Escape Energy rather than partial escape energy so forms a positron+electron pair.. It's +ve cells (base quanta) close-packed by free-flowing, compressible, displace-able -ve electro-gas trying to stay balanced. Out of place cells and the excess -ve gas left behind are repelled into balls. All forces emerge from the base electric force and two base particle types, very neatly, semi-classically.

Huh. Where does all the extra mass energy come from? Also, electrons + positrons don't even interact using the strong force. Where do the quarks that make up the hadrons play into this, and how does the strong force emerge.

[@PrivateSi]

@@sophiophile .. QCD, QED, QFT are fudges that obscure as much as they predict to me. There is a Mass Multiplier Mechanism for protons and Mass Addition Mechanism for everything else... The simplest, therefore most probable MMM is trapped field, due to the fully neutralised electron, with two half neutralised positrons. An inward field warp to (locally or absolutely?) max-packed, solid core... -- In the flow model version electrons and positrons are -ve gas pumps, and positrons continuously attract and and electrons trap 1 quanta of -ve gas away from the rest of the field so voids expand (and galactic space compacts?)... I am not sure if a Proton's dark energy contribution is related to the number of positrons and electrons, or trapped field (mass). This will take some maths. -- Sternglass Muon Model for exotic matter and QCD alternative. Pilot Wave Theory for double slit experiment.

[@sophiophile]

@@PrivateSi Dunno anything about Sternglass Muon Model, but the I'm not sure how pilot wave theory fits into this. I'd enjoy reading if you ever write something including calculations.

Nature charges $11,690 for the article processing so I can see why they might let a few things slip.

Is that the eperiment on attosecond,opens to humanity new view' s about new tipes of matematics where miror numeric paterns and quarters of numeric fixed paterns can lead,to new chemistry's specially and much more fast and simple understanding arround functionality of everything as "an all".What do you think Sabine?I love Schrodinger but not the way he approuched the cats🔎

Fantastic. As one who measured uncertainty down to 6 femto seconds, using a million-dollar machine. Complex yes but useful.

[@thepuma2012]

I found that fascinating, about that research on electrons and do those measurements in the attoseconds, wow. Would like to see more about that, it s very interesting!

Recently reviewed a social science article deriding non- standard definitions of the subject parameters. It appears this is affecting many branches of science, especially the younger ones, whose definitions are also relatively new.
