"I've always wondered why meteors land in craters." I'm in the right place to learn.
It is even more strange - they seem to know were craters will form!
I wanted to comment on that. That joke got me good.
Im thinking the meteors grow there and then the craters crash into them
God knows them all by name.
So they don't roll off ?
It's so good to hear Sabines doubts about theories and findings. Usually everything is presented as a fact in media, and when it is proven not correct it just fades away.
And then it's relegated to use by "do your own researchers" for decades or centuries as 'proof' of the flood of something 😂
🙂🙂🙂🙂Yes.
Thank you! Your humor gets me every time. I am still cracking up over the "Quantum Computer Help Desk; turn it both on and off".
“allow computer to remain in superposition, do not observe for up to 30s”
"A system that generates text without knowing anything about it. I think you don't need help in that".
Ouch, it's valid around the world, I would not limit it to one region and I would not limit it to one group of people either, it's very universal, you can find many examples and sometimes it's me when I get things wrong of course ;-))
And yes, both off and on at the same time, perfect condition in the quantum world, mapped on the most helpful help desk answer ever ;-)
What a great sense of humor!
@@richard--s do people actually think superposition is real? it's just an estimation of method of predicting stuff we can't measure. it's not literal
My first scientific insight was to wonder why volcanoes always occurred at the tops of mountains. I cannot recall what age I was, but the question gnawed at me for years. I eventually earned a PhD in geology (by which time I had managed to figure out the answer!).
Well come on, tell us why!!
@@schoo9256 It's to give the meteors a challenge. A conical volcano is essentially an upside down crater. 😁
@@another3997 where is the indentation on the other side of the globe 🤔?
@@jorriffhdhtrsegg Unfortunately since under the mantle is a molten liquid the matching indentation is a non linear solution (chaotic), so we need to train up some brain cells to spot a pattern before they die in a petri dish crater.
@@another3997 Is that causation before the action? lol
There HAS to be a 50s/60s B-movie where the monsters were called "organoids".
all i could think about while she said it were the 'orgones' from peep show
Hah. I was thinking about using in common parlance. Possibly as an insult .
there was a video game where mankind used biological spaceships and technology called organids,
it was called genesis rising the universal crusade
I used to watch an anime called "Zoids" when I was a kid where some of the protagonists' mechs used "organoid systems".
Captain Scarlet and the Organoids 😁...sounds good to me.
"I don't think you need help with that." I laughed out loud.
You gotta love Sabine. Her sense of humor makes these video's truly fun to watch. I wish I had teachers like this in school!
You are so right. She is hilarious with her dry sense of humor! Love it.

@@pumbaa667 (sorry, there's a language trap like so many... there is no s in "information" even in plural. It's not logical. Well, some people might find it logical maybe, but it's just the way it is.
In one language we look at multiple pieces of information and we have a plural form for it. But in another language "information" is "information", it does not matter if it consists of many aspects of things here and there or not, it's always "information" ;-)

This is my favorite science channel on youtube. Excellent videos with a touch of dry humor.🙂 Great job Sabine!
Good to hear that MOND is getting some points in its favor with this discovery. Keep this parts of cosmology interesting.
Thank you, Sabine, for that great update !
The humour in these videos is brilliant. Great stuff as always, thanks!
Sehr interessante Themen und trockener Humor, gefällt mir :)
That joke on Rishi, was exquisite! 👌
And probably well-deserved
There are two prototypes of BritGPT already. They're called "Boris" and "Lizz". A bit underwhelming though.
Boris often output gibberish and Lizz got stuck in loops and was prone to crashing. Both made the Maybot appear strong and stable in comparison.
It had me in stitches. Did not see that one coming 😂😂😂
Exciting MOND news. Thanks for covering this. Guess we wait and see what comes next.

Enjoy MY WEEKLY update of Science after a week of local news that dumbed me down.
So much info, my head is spinning. Thank you, another great presentation SH.
Thank you so much for this content ❤️
With your weekly science news not only do you update me on topics that I would never have known about but your disenchanted comment also cleans it of gobbledygooks. It's like killing two birds with one stone. Many thanks Sabine
Two birds killing one stone
first news is basically: scientist want to build mother brain from metroid series
"Scientists working on OI found mysteriously murdered and turned to dust"
Amazing! Thank you so much for making these
Really love your videos. And, the tongue-in-cheek humor always makes me chuckle.
"All this really happened during The Stone Age, but the time is an illusion anyway."
I was thinking exactly at this fact before Sabine confirm that. I wanted to google the distance in light years but Sabine gave me the answer too. She's amazing.
Wow. I had indeed not heard about MOND predicting these giant galaxies. This is getting really interesting.
Virtually anything that acts on such a big scale in space 🌌 would cause big galaxies though. That is just how cause and effect with randomness works. 🤷
MOND still isn't a slam dunk as the explanation for dark matter though. In the latest PBS Space Time video about MOND, Matt talks about several aspects of dark matter that MOND is less able to explain than the competing theory that there's a new form of matter waiting out there to be discovered.
He also raised the issue of the growing number of MOND models are out there as more data about dark matter comes in, and we all know how critical Sabine is of the theorists continually coming up with new models as the existing ones are shot down. She can't have it both ways!
Personally, I have no skin in this game -- a solution to the dark matter problem would be fantastic whatever it turns out to be -- and I don't understand why some people (outside of those actually working or reporting on the issue) are so invested in it being one over the other.
@@EnglishMike The thing is dark matter is not really disproven at all by this either.
The universe 🌌 could have just started out randomly and virtually anything that transmits information faster than light 🔦would have the same effect with randomness (e.g. rich 🤑 people are only so rich because poor ❌🤑 people are doing economic stuff, for their businesses to make money off 💰. If they were not causally connected, the rich 🤑 people would have less money💰).
It has less evidence for it via this, which is not the same thing as evidence against it.
@@UniDocs_Mahapushpa_Cyavana If true, MOND doesn't disprove dark matter, it will simply replace the (apparently endlessly misleading) placeholder name of "dark matter."
Dark matter -- i.e. the observed gravitational discrepancy between the current theoretical models and actual observations -- will still exist. If MOND is correct, however, then dark matter will finally be explained, and the term will be discarded (eventually).
@@EnglishMike I mean... MOND could exist and just make the problem 🧩 worse.
The universe 🌌doesn't have to be helpful 🧰 to scientists 🧑🔬.
😹😹😹😹😹😹😹😹😹😹😹
Thanks Sabine. Great vid as ever.
You are so coooool Sabine. Keep up the good work 😀
I am SO GLAD we are finding more evidence for MOND over dark matter. When I was a kid, I always thought that solving this would be such an amazing scientific advance to live through.
Personally, I await the future Linus Tech Tips video about optomizing the nutrient solution for my neuronal organoid gaming rig.
Thanks Sabine! I get so much of these news items but it's difficult or expensive to get the real facts.
First time watching one of your videos!
Thank you for your work and the way you present :)
"So it's backwards causation? ... I always wondered why meteorites land in craters." 😄 Ah, Sabine. You make so many enemies in physics. 😁
Those people are larping as scientists anyways, when all they do is worship a theory and building a house of cards around it, only to ignore what they see and instead of adjusting to the evidence, they just make up mathematical artefacts to prep the model and call it a day...
Those are more cultists then scientists, einstein is their prophet and the standard model is their bible..
Is there any hope for post Einsteinian physics or are we doomwd to scientific stagnation?
@@SebastianA.W. Your not wrong except in the fact that Einstein's Relativity keeps racking up evidence and the Standard Model of particle physics has solid evidence until you get to the right of the electron and electron neutrino and also the non-photon bosons. In those areas the data is really fuzzy. That framework exists because of their love affair with symmetry.
You should make a video about logic based learning, or using Symbolic AI. It allows for training models with much less training data by training them to learn logical relationships between concepts. It's fascinating
Great video. Thank you!
Thank you for the news.

Hello Sabine, does the view on early galaxy-development also support what you are working about (superfluid DM)? again thank you
I remember her saying she isn't sure what side of the Einstein field equations the terms for "dark matter"/MOND belong to i.e. do we need to change how gravity i.e. the metric works or to add the terms to the matter side of the equation so she seems pretty agnostic other than that models can't ignore the observational constraints of MOND just because they are inconvenient.

I've always wondered about probability of decoherence with larger quantum computers. Couldn't it be the case, that increasing the number of qubits or gates requires exponential (or polyonmial with a high degree) amount of effort? Why does it currently happen that they decohere? Is it even the limiting factor to the size of the quantum computer? A video about that topic would be really interesting.
actually the effort is linear, at most logarithmic. Typically the results are probabilities, which become lower, higher variance, with increasing number of qubits, decoherence is increased as indicated. To minimize the uncertainty the computation has to be repeated .
The thing that I've heard from other channels and other individuals in similar computer science field but not specifically Quantum Computing is that for artificial intelligence to really work there's going to be a rate of error and simply if you can get that Beyond human fault you're good to go. Another proposal I saw was specifically with Quantum Computing is that they may reach a point where they have to have a discrete digital processor for certain high-precision forms of computation and in the lower Precision significantly faster things would be handled with Quantum computing
@@Arturo-lapaz lol. logarithm grows slower than linear. you seem to clearly NOT know what you are talking about.
You leave me speechless and clueless. Respect
@@stonemannerie correct its (X x ln X), sorry.🇧🇴
I mentioned this in a comment on your previous video, and I still wonder if this could have any implications in something such as quantum computing.
Have you read about the Quantum Twisting Microscope developed in the Weizmann Institute of Science? I read about it on Israeli media last week, but if there's a serious development in this it would be interesting to hear a better explanation of what it might be able to be used for.
It was basically stated this microscope is able to measure the quantum properties of electrons without making them collapse into particle state. It was said that instead of having a sharp nanometric tip as in a scanning tunneling microscope, it uses a 2D layer of a quantum material such as graphene to measure electron tunneling at many different locations simultaneously.
This is as much as I understood.
I literally just read it 20 secs ago

With the Webb Telescope peering back in time at incredibly distant galaxies, I'm just waiting for it to observe a galaxy that is older than the accepted age of the universe to really stir things up in cosmology.
Things are a bit more tricky than that as one criticism that hasn't been adequately addressed by cosmologists is that within the full Einstein field equations the link between spatial look back distance and measured redshift is model dependent, i.e. depends on the curvature along the light's particular geodesic path through spacetime, thus if the choice of model is incorrect the estimates for distance will be incorrect. Given the many problems with the standard model of cosmology which have largely been ignored by the cosmological community at large despite their huge statistical significance (now several sigma standard deviations higher than the supposed evidence for the standard model) it seems safe to take anything from the mainstream cosmological community with a grain of salt at best.
@Conon the Binarian yeah, that would be HD 140283, which was eventually determined to be 12.01 ± 0.05 billion years old.
@@brandonletzco1433 Yeah though there were many uncertainties in the sense of calibration which have made this measurements less problematic. We do have measurements of several very old stars which given what we have observed more locally like small stars forming as satellites of more massive stars or more distant galaxies measured at far higher redshifts than we had generally accepted which is usually taken to mean they formed far earlier in time.(The H alpha break in light is a pretty good independent proxy of the redshift during the time or reionization if you assume reionization all occurred and ended at roughly the same time periods everywhere but that is an assumption)
Big Bang theorists will simply add another couple of free parameters and say all is well. The universe is far older then the Big Bang suggests.
Probably not, though books could be written on what is meant by "older". But we've already seen the space-time result that beyond a certain distance, the further away galaxies are, the bigger they appear to us. They seem to be growing, but alas, are not.
Fantastic Dr. H! I don't know how you have time for your family and life, with all the great, clearly researched, and humor-improved science news reporting you produce!

2. Quantum computing error reduction - in context of ANY feasible development of usable quantum computers - MAYBE bringing them closer to the Star Trek record of 60 years before realization (but maybe they will achieve success early with yet to be unknown physics process too!?

I really love your content, it's really good even compered to other sciency channels, yours is best made, best explanations, best food for thoughts.... I don't really want to say it, but your quality of footage could be better, I know, I know, its good enough for what is meant for. Anyways getting a better camera, preferably one that doesn't do chroma subsampling (4:4:4) or one that does less of it (im guessing your does 4:2:0, as it's the default for most consumer cameras at this time, so 4:2:2) would give you much better and sharper chroma key on on greenscreen, because of higher resolution in color channels. Not that long ago you couldn't get consumer camera with subsampling better than 4:2:0, you had to go professional, but because of moving the video from rec.709 to rec.2020 the producents are making now consumer cameras with much better quality.
Sabine, please always add a link to the video description which directly leads to the moment the telephone rings. Thank you! If you support my request, please upvote this comment. Thank you!

When I was writing a paper on Dark Matter a few years ago, I featured MOND saying, that's probably not it but we also don't know what particles could make up Dark Matter.
Look where we are now...
There are enough physicists working on and who favor MOND that if this really is a slam dunk for their models, the debate will be over. I guess we shall have to wait and see what happens.

Thanks Sabina!
Now all I gotta do is live long enough to have my brain made into a Minecraft server.
Hi Sabine, as MOND is getting traction these "days", I wonder whether this could bring some credibility to the quantized inertia theory (which is admittedly quite controversial). I mean, despite some good predictions, MOND brings no explanations as to why the gravity is different at larger scales, while QI does (... as far as I understand it, which is not much) (*). Maybe a mind like yours could help debunk that, or at least, point to its shortcomings?
(*) I understand it's relying on the Unruh effet - not observed yet - as the root phenomenon causing inertia to only "happen" above a certain acceleration level. And because this is link to the universe's horizon (I don't remember which one), it looks to me (naively) that this could also explain why the universe expanded so rapidly near the big bang. How wrong am I? :)
Quantized inertia has some major problems which prevent it from being a valid scientific theory at this time namely that it is incompatible with some of the core axioms of mathematics used to derive all of Classical mechanics General Relativity and Quantum Mechanics and thus would require one to derive an entirely new mathematical framework in order to actually test anything or even develop basic conclusions. After all the axiom of Quantizing Inertia effectively from a mathematical perspective means that you can not use differential geometry quantities and principals in your theory.
All of physics from Newton onwards is exclusively written in the language of differential equations and thus is fundamentally incompatible with any self consistent QI framework.
Until a self consistent formulation of QI can be derived which can also explain why the large scale limit is consistent with differential geometric interpretations and models, QI is not able to be anything more than and idea and any framework which tries to use formulas derived and written in a language incompatible with its principal axiom is pseudoscience at best in the same way trying to use Newtonian gravity deep within the gravity well of a black hole or Neutron star is invalid.
@@Dragrath1 Thanks for the detailed explanation. It seems to me that building a new theory based on some core physical principles and deriving the ad-hoc mathematical framework wouldn't be a "first", but I understand the likelihood of a successful outcome is pretty thin :)
I now curious of such an example of inconsistency ... ^^
I absolutely loved this. Sabine is the best.

@Smee Self ? Sorry I don’t understand
@Smee Self not in space there aren’t!
@Smee Self ahh yes sorry I forgot, however PLANK is no where near as powerful as JWST and it can’t see anywhere near as far back or in as high a resolution as JWST
@Smee Self ok but what I mean is even in the infra-red wavelengths the 6 distant galaxies still had extreme red shift, if we had a more powerful telescope which can detect even longer wavelengths, we may be able to get a better view of those galaxies or even find ones beyond! Imagine that, a galaxy formed less than 500 million years after the Big Bang! Due the the nature of the acceleration of the expansion of the universe (English is a great language!), it’s unlikely we’ll still be able to detect any light from the hot early stages, but maybe an early star! Oh and if black holes are worm holes or Einstein Rosen-bridges then just imagine if we peer into the early life or previous lives of our own solar system!

Lots of ethical questions about OI. How do we determine whether it's conscious? Even if it feels no pain, is it slavery? Would neurons from an animal brain -- perhaps a cat or dolphin or octopus -- eliminate some of the ethical concerns and work as well as human neurons?
Who cares. If it complains, punish it with more pain!
I agree. Ethically, I think we should skip the whole thing. AI is racing towards its own ethical crisis. Let's deal with that first.
The human brain needs almost 100 billion neurons to be conscious. And many humans barely reach that benchmark. I think you can stop worrying until someone gets 100 million neurons on a chip.
