Dr. Sabine, How/what do you think is the obstacle from being able to implement consciousness in AI ?

Dr. Sabine, what would you suggest is the best way to study Very Abstract topics like Discrete Mathematics etc? I believe its no different from studying Nuclear Physics... its so abstract.

Please stop being patronizing about the NHI issue. Yes, your goal is to make an entertaining program, but don’t cherry-pick the weakest possible stories on UAP, NHI, et al., just so you can take cheap shots at the field. For those of us who, unlike yourself, actually are physicists who know the field, this kind of silliness is insulting.

​@@richard_loosemorewhat are those things?

[@richard_loosemore]

@@DavidOfWhitehills UAP = unidentified anomalous phenomena (new government-speak for “ufo”). NHI = non-human intelligence (new government-speak for “aliens”). The first term was introduced by an intelligence officer called Jay Stratton when he was trying to get the issue destigmatized within the intelligence community, and then it became the new normal. NHI has been around for a while but was recently introduced into official documents and legislation, again to get around the stigmatization problem.

The last time I saw Saturn with its rings edge on was through a 100mm refracting telescope in my garden. Although the rings weren't visible, their shadow was and it looked amazing! It made Saturn appear as a bright disk that was perfectly divided in two by a straight black line. Shortly before and after this, the view was equally amazing as the rings were only visible as two thin white lines that extended out from the disk, perfectly aligned with the black line that divided the disk. If you have a telescope, well worth viewing!

Regarding the paper 2021 of Ucar, ”Polarity Free Magnetic Repulsion and Magnetic Bound State”, the abstract states “Working principles of these effects are provided within classical mechanics and found consistent with observations and simulations.”. If one examines this paper, the equation of motion derived in DTU article (excluding the damping) in Supplementary Material is already in Ucar's paper in the extended equations at the Section 5.1.6, using the parameter (k) which can be defined in initial conditions, also present in the Appendix as a special case. Ucar also clearly states that the phase lag, the key factor of this effect, is the characteristics of the driven harmonic motion.

The recombination glow of oxygen is usually UV then red. The first transition is two monoatomic oxygen recombine creating a UV photon, then the siglet oxygen decays producing red light. The green light is likely coming from excited carbon monoxide from the extreme UV hitting it this would give green light followed by a mid wave IR emission.❤

[@johnnyllooddte3415]

its not oxygen.. its methane and ammonia, just like jupiter and uranus..."The observations at Mars agree with previous theoretical models, but not with the actual glowing we've spotted around Earth, where the visible emission is far weaker," Gérard said.

[@mikebarushok5361]

I think the bigger problem with using photovoltaics to "power" smart devices is that smart devices are always controlling and connected to something that has a power source. The device doing the controlling is consuming a negligible amount of power compared to the device being controlled. The idea of "recovering" otherwise "wasted" light energy is at best a meaningless gesture and at worst creates problems of positioning and of additional circuitry to function both when light is available and when the room is darkened.

[@BariumCobaltNitrog3n]

So worst case scenario is that a person will have to install the panels and connect them AND find a place to put them? How is recovering unused energy a meaningless gesture? I don't see the point in a comment that says, "Don't do this" before seeing an idea implemented, and offering no solutions.

[@TheJunky228]

the spinning magnets reminds me *strongly* of several 'ufo designs'

[@Pushing_Pixels]

Regarding the spherules found near PNG: The Meteorite they are believed to have come from was tracked by the US military, and they deemed it to be of interstellar origin based on its speed and trajectory. That was the primary basis of the claims of an interstellar origin, not just the composition of the spherules themselves. The claim that the composition was unusual, and potentially artificial, was based both on the composition itself, and also the fact that they survived entry at the speed they did. Objects with a composition typical of our solar system would not have made it to the ground. Dr. Loeb has stated that currently available man-made alloys would also not be capable of surviving an entry at that speed. That, and the fact that we apparently can't make alloys of their nature, was what the claims of an artificial construction where based on. So, either you didn't represent the Arizona State researchers' paper correctly, or they are debunking a strawman when they say it couldn't be interstellar. I would check it myself, but your references are paywalled.

when you can drop a 1000 tonne solid alloy from space into the earths atmosphere and measure whether it survives or not.. give us a call.. its just fanciful theories till then

[@JungleJargon]

Nice illustration! Now if we can get people to see that there is little to no gravity to slow down light between galaxies until the light enters into a galaxy where time slows down and distance contracts, slowing down the speed of light. This is the reason superluminal motion is perceived to be seven times the speed of light since our measures of time and distance are being projected into outer space where time runs faster and the measure of distance is much larger relative to ours. Of course nothing ever exceeds the speed of light. It’s that the assumed measures of time and distance are off. Another little secret of general relativity is that the speed of light is NOT constant because the measures of time and distance are not constant throughout the universe. Looking at a galaxy is not like looking at a cat or dog where the measures of time and distance are constant because they are not constant from here to outer space between galaxies. The measures of time and distance appear to be constant or flat to us locally but they are not flat over great distances, especially outside of galaxies and in between galaxies.

[@melchiorvonsternberg844]

Liebe Sabine... Why was it not mentioned in the information about Avi Loeb that NASA data on the trajectory and speed of the impacting object suggested that it was of extra-solar origin?

[@danieloberhofer9035]

​@@EinsteinsHairfyi - outside of very rural communities, Thanksgiving (Erntedank, you spelled it perfectly) is rarely celebrated in Germany. It's no public holiday and there's practically none of the traditions North Americans cherish. No family reunions, no turkey, no eggnog. I'd have to look up the date tbh, because no one really cares. I'm sure there's a special service in my parish, but since I'm more of the "church is for christmas" type, I'll probably miss that, as well. Anyway, whatever you might've found online about special dishes and the likes: Forget about it. That's probably as accurate a representation of life here in Germany as is the stereotype of Bud Light drinking Americans that have a barbecue for every single football game. There might be some. There might also be some Germans who have "Sauerkraut Casserole" for Thanksgiving. The vast majority will probably be very different. That Sauerkraut part still made me laugh - partly because that particular stereotype seems to be virtually indestructible, partly because just last week I made a dish like that for my family for the very first time. Wasn't bad, either.

7:27 China's plan to use automatons on the Moon, is actually a good one. The fact that for their first attempt they go straight for the high tech deployment, however, is not a good plan. I'd first send a few automatons to create a regular landing site, deploy GPS beacons, and whatnot to allow for smooth automated landings, as well as take-offs, and then try something akin deployments of advanced measuring equipments concerning gravity, but not the other way around. Build a foundation first, then a building. Building without foundation hardly ever works out well. And yet, kudos for the first remote operated machines on the Moon. Combine the landing site with a Lunar sat for communication, and voila, crystal communication and high speed. I'd also recommend a 3D scanner, so you can do topography and sim the Moon surface to check where buildings need to be and such. 3D VR then leads to accurate placement and building. This alone can lead to improved automatons with more heuristic skills. Instead of going "pick up brick" "place brick" a couple thousand times may then be replaced by "build house"

Are you all so ignorant? Never heard of LGM?

[@Darisiabgal7573]

I have some astounding and totally shocking news!!! Everything in our solar system originated from interstellar sources. How is this possible. Within our visible universe the was a first set of stars, everything else was between those stars, interstellar. Since our sol is not a first star then its system components came from between the stars. And you might argue that our solar system is also composed of those first stars, as much as this is a little true, once those stars went supernova, their remnants were interstellar. And so we have a semantic problem because, as we see above there is a flux. And you could argue, well the flux has subsided and is no longer important, but in fact a major source of high enery protons, hydrogen and helium particles originate from extrasolar sources. And occasionally the cosmic ray detector in Antartica registers particles with about the same kinetic energy as a thrown baseball. And so its nothing new or shocking that particles from interstellar space are entering our system. Jupiter occasionally ejects objects from the system and those objects wander around space occasionally crossing other stellar systems. And so the material flux between stellar system and the occasional supernova is not dead, and so its kind of foolish to believe that interstellar objects is evidence of anything more than the natural evolution of the universe.

Actually, it's just covered in bald Little Green Men, and it's hugely overpopulated.

3:38 People like Avi Loeb are the reason why I ignore status entirely. xD Only competent people earn my respect.

[@NondescriptMammal]

Why is it that all we ever get are artist's impressions of most of these spectacular discoveries? Mars glows green! Our spacecraft has detected it! As proof, we will now show you an artist's impression of it!

[@johnnyllooddte3415]

because it cant be seen with the nekked eye

[@NondescriptMammal]

@@johnnyllooddte3415 Surely the spacecraft that detected it, also photographed it?

[@rupertkingsley]

Green glow comes from the dark side? Darth Vader’s mood lighting 😂

[@millennialfalcon1547]

The interstellar origin of Avi Loebs object was determined by the SPEED of the object, not by the composition of the materials. This is exactly the same method used to determine that Oumuamua was of interstellar origin which no one disputes.

[@johnnyllooddte3415]

except the umpaumpas dispute it

[@YellowPenetrator]

5:27 seemed like the wrong, but nonetheless interesting paper 🤔

[@ZMacZ]

4:54 Oh plz, remnants of stars and planets can easily have produced it. Did you know that any planet caught by a star's gravity in such a fashion that it spirals towards the star has a part that is flung away from it ? The gravity with the decreasing orbit sends the nearest at a speed higher towards it, but equally, the part from the planet that is furthest gets accelerated beyond a regular sustainable speed for the nearest part. Not all such spirals result in headon collision with the star, but may just attract a part of the planet, leaving the other part being flung outward again. If the planet had an already formed surface, this would be flung into space, breaking in separated particles as the flung happens. If any such part has an escape velocity and trajectory, well, +10B years later it shows up here, never even having been populated, let alone having had an advanced civlization. The remnants can also be from earlier planets within the Sol system itself. It's also highly likely that Sol, after it's conception, had many more planets and/or planetoids. From the conception of any starsystem, the first years everything is unstable. Only once the system becomes older it stabilizes, until either something similar to Sol happens, settling with many planet and planetoid bodies, or until the last remnant has been swept up, leaving only the star. (Exceptions are rogue planet/planetoids.)

I made my own quantum computer at home using a seashell and a jar of honey. First, orient the seashell to best express the problem, then pour honey on it. Wait a few hours, and wherever the honey is left, that's your answer.

[@johnnyllooddte3415]

thats the bees knees right there

[@Flum666]

Green is obviously better than Red, so good for Mars!

[@Flum666]

I've just been informed that Red and Green aren't real, but is just a wavelength in the spectrum, sorry about that, we'll be returning to our normal program schedule.

[@TheAdeybob]

sooo...is there no way to measure the moon just by framing it from a decent light-distance, and then comparing frames to see if dimensions have had a wobble. Gravity has the same 'speed' as light, after all, and it's more than possible for an object in space to provide a stationary viewing platform...so what gives? Seems relatively easier to place dedicated viewing platforms linked to onboard atomic clocks on several cubesats, than is the proposal as outlined in the article described. One wonders if there will be 'strange' outcomes if such a big part of spacetime is measured with such accuracy within a 3d space..? ..a bit like the unexpected outcomes of the 'light-slit' experiment perhaps...but after you flip it and reverse it, to quote a great sage (and brilliant artist) of our time, Missy Elliot?

[@DragonDrop4758]

I enjoy your humor because it is so outlandish, creative and similar to mine. :)

[@rtkracht]

You never fail to make me smile (sometimes more than once). Thx

[@harlycorner]

Is this news about spinning magnets a joke? I showed the same spin thing to my friends about 15 years ago. Does it mean now that I actually had discovered something that nobody was aware of? What the hell is going on?

[@0neIntangible]

Now if those nanowire neural networks could incorporate selectively placed ano-capacitors to simulate synapses...

[@johnnyllooddte3415]

not without rebooting

[@balok63a40]

The disappearing rings of Saturn was observed by Galileo. He didn't realize that they were rings because they were almost edge-on the first time he saw them., so all he saw was two points of life, one on each side of the planet. He famously commented about Saturn once again eating his children.

[@mathewward6229]

It was a bit rough to Avi Lobe he didn’t make out definitely that it was extra solar he pointed to the evidence of the very high speed impact and hoped to find something. It still science worth doing even if nothing significant is found. Perhaps a null hypothesis this time, perhaps not next time.

[@KeithCooper-Albuquerque]

Great video again and still very funny!

[@agoogleuser4356]

Do they DISTORT space and time or do they SHAPE space and time? Re Gravitational Waves. (I am still learning is the smartest thing I can say about me.)

[@BrodyLuv2]

Distort is to shape, no ?

[@bramfran4326]

a "Masterwork of logical deduction" 🤣🤣, perfect🤣

[@V000idZer000]

The paper shown at minute 6:26 is about Betelguese, not spherules (:

[@damianousley8833]

Mars has a phenomena similar to Earth's sky glow, which makes Earth's night sky brighter than just starlight alone, interesting. Better off doing astronomical observations from the Moons surface from very large telescopes in the future. Just enough gravity on the moon to be handy and not an incumberence.

[@jeffreycohen2234]

Didn’t Loeb qualify the alien stuff with “maybe” in each case, not “is”?

[@MrDino1953]

You can claim anything by saying maybe, but then the claim becomes worthless.

[@_aullik]

I'm currently debugging one of my programs and i came to the conclusion that aliens must have written that part cause i cannot remember and it is really strange.
