So... Dark Matter isn't just invisible, it also has random properties that change according to whatever effect you want to explain. I think this is an amazing discovery with an unlimited amount of applications. For example: next time I'm late for an appointment I can perfectly explain this with Dark Matter having a bad day.
I keep hearing rumors about Dark Matter being based on Newtonian physics applied at a Relativistic scale (measuring the mass of galaxies/the universe) where some Brazilian paper made it almost entirely disappear by using a Relativistic model.
@@anarchisttechsupport6644 I dunno, that description makes pretty close to zero sense to me. The way to measure mass distribution in a galaxy cluster is to figure out a model that replicates the effect of gravitational lensing through that cluster. That model is based on general relativity (gravitational lenses come from general relativity). I don't see where you'd use Newtonian physics there, nor what you'd want with relativistic effects. Maybe you mean the galaxy rotation thing? But again, it's unclear to me how relativistic effects would help in that context. General relativity is our current theory of gravity, and until you're looking at gravity strong enough to create frame dragging, I don't know of any gravity effects you could reasonably call relativistic. Maybe there's something I don't know, but I thought I understood at least the basics reasonably well. Now if you're talking about theories that try to explain this stuff with "modified gravity", all bets are off, because you're essentially inventing your own formulas at that stage, with - as far as I can tell - the only idea that it has to reproduce the galaxy rotation thing. I haven't heard if anyone managed to explain lensing effects through a cluster that way. Or maybe the idea is modified gravity for galaxies and dark matter for more irregular effects like those lensing effects? Sounds a bit arbitrary to me.
@@mitch_the_-itch 'Dark Matter' is supposed to interact gravitationally with the universe but, as deGrasse Tyson pointed out, 'Dark Matter' should be called 'Dark Gravity', since a discrepancy in observed apparent gravitational force from what is predicted by present physics is thus far the only measurable evidence we have for the existence of any such thing as 'Dark Matter'. 'Dark Matter' got proposed as an explanation for that discrepancy. The data never lies but between the data and the interpretation falls the shadow.
The brazil nut effect - isn’t that the same effect that forces you clear the potato field for rocks, year after year? No matter how many rocks you clear, new ones pop up next year?
Before watching the video, I mention to my mathematics and quantum mechanics loving 17 that a new paper suggests that dark matter acts like waves. His response? “Oh really? I’ve read a lot of papers on dark matter and they’ve all been wrong.” I roll my eyes and then watch Sabine. Guess he was right again.
Amazing content as always, Sabine. Would you consider doing a video on mycorrhizal networks? There seem to be some controversy about the topic currently, as the original study was published in a questionably scientific way, and it even became the basis for the highest grossing movie ever. It'd be interesting to know the reality behind the "talking trees" theory.
Also it has an effect on the phosphate retention (as I have learnt from a TED talk). Quite important considering the discussion around 'peak phosphorus'
Its no Theory its Fact. But talking trees? ahh what? 80% of all Plant Life HAS to have Fungal counterpart or else it will die. As most plants cannot Fix Nitrogen. Fungi just naturally form "networks" its what they do. The networks are the Fungus Body essentially. We call these Hyphae. This strand filament looking things that are quite similar looking to a Brain. Now do they respond to pressures and react spreading out Nutrients and other stuff? Yes. Talking? Meh. You get a Cut. Swelling Occurs. Your body singled other areas to bring in stuff to help. That is what is happening. Weird Analogy but this Evolution Strategy, using each Piece or "End" or your body to relay information well to the whole. Instead of relying on the Whole's Features for that information. Is exactly like how Napoleon won so many battles. He created smaller Cores and gave them more leverage to act on information. Which is far more efficient. We also do that to a smaller extent. You foot tells your brain it hurts.
Re: the nanowire network, I think it’s fascinating how complex systems naturally (so it seems) form this type of structure, such as the brain’s neural network, galaxy filaments, tree root systems, and so on. It’s a seemingly efficient structure to pass on information and resources (plant nutrients, hydrogen, etc.) Very cool!
The glass nano wire network and how they are using it reminds me exactly of the wizards' computer at the Unseen University at Ankh Morpork in Terry Pratchett's Disc World series. I'll lay odds that the scientists at play here can tell you where the counter-weight continent is, too.
Ma'am. Thank. You. You're way of breaking down the terms so it's easier to understand for those who only had high school level sciences? -chefs kiss- I greatly appreciate it. Adding in your lovely humor, sarcasm and accent, I LOVE spotting a weekly news update ❤ It's also a fun way for me to keep up with new topics and scientific findings. No idea that maglev cars would have potentially been possible, but contemplating it... the idea of freezing to the road brings to mind more wildlife issues.... And what happens if a car "falls off" the road? Would need fully automated cars to attempt adjustments at that speed. 🤘🖖🖒🖒🖒
Back when my dad was still alive, I tried to explain what I did in Computer Science. He thought about it for a bit, and came up with: "computers are just a bunch of tiny wires". I wish he were alive to see this video.
I love that you don't just categorically accept that dark matter must exist. It may, it may not, we're still unsure, and you communicate that uncertainty where no other science communicator will. Such a relief that at least one person is allowing for the possibility that the theory could be wrong.
The superconductor highway is absolutely vacuous. You might as well replace the entire network with high speed rail at that point; I don't understand why they think making each car a mini maglev and retrofitting the entire highway system is more efficient than just expanding and upgrading the rail system. Completely bonkers.
Ok so in my memory this is a pretty small 50k science channel. So when did you get to almost a million??? Congrats you deserve it but i genuinely did not notice this channel explode!
Sabine, I find your sense of humor refreshing. I'm just a regular human with some interest in science, yet I find dark energy and dark matter to be constructs by humans that are unable to understand our true nature of the universe. We are learning so much over the years yet we seem not to understand the most basic and fundamental aspects of our universe. Over our lifetime we have gone from the Atom being the smallest thing and it being a smaller model of the solar system, to quantum fields and particles popping in and out of existence from where? I doubt very much that we will ever find out in my lifetime what the true nature of our existence is. Right now I'm in the great state of Utah looking at a large reservoir of water being blown by the wind. The sun is reflecting off of the surface of the water and Waves. There are some white caps on the top from the wind. It reminds me of a video I recently saw about quantum fields. Is there such a thing? And is it a particle or wave? What's real? And what really is real? And then there's time.... Used to be time was just something that passed or like the flow of water down a river.. now it's tied into gravity and space and particles and Fields and, truthfully it can make my head hurt. I appreciate you making the pain a little less with your knowledge and the way you present it. Thanks!
"Spacetime crinkles" sound like a breakfast cereal for astrophysicists, you just need a big enough bowl and pour just a portion of the milky-way. But the French fries with catsup joke was better than mine.
Sabine, you might be a good match for Dr. Sheldon Cooper. Seriously, I love your work here. You teach us things in a way that is understandable to the common man. Thank you.
Speaking of waves…. (I’m no physicist disclaimer). I’ve been reading about sound; it is a wave yet some reference it as a particle. And the wave has no mass and some readings consider it to have “anti-mass”. If it has no mass, yet has acceleration why is its speed slower than light? Sorry if that’s a simple question to you and your viewers. I had one other question I haven’t found the answer to (well “one” of the other questions). If matter enters a black hole and is ripped apart at the atomic level does that mean that the matter transitions through the spectrum of elements by the breakdown of the matter as electrons and such are ripped away? Ultimately ending up back as hydrogen before being even further disassemble? And I’m assuming to be compressed into some new type of material as it is ultimately compressed into the singularity? Please forgive my ignorance and please use small words lol. Ps. Love your sense of humor. Rob from Texas.
@@SabineHossenfelder the crinkles are darkmatter higher density formations. Yes i agree saying wave like implies particle. Black holes have emissions of non baryonic matter... they are folding over 3d string membranes into hooks (aka non baryonic matter) or ripping them... blackhole at center of galaxy is constantly emmiting this non baryonic matter this the search for darkmatter particle is a waste of time and money... doesn't exist. Accelerating expansion past speed of light at any point is illusion... i recently created a new theory about a toroidal universe... in this universe you have regular light speed and negative light speed and can allow basically illusion of faster than light expansion up to 2x lightspeed... past that has to fundamentally be a illusion.
Does the Brazilian nut phenomenon allow for seperation of charges this way as well? Wouldn't this then be practically free energy (probably not, for physics reasons) if they just return to the ordered state just like that what then would allow to extract the potential energy again?
I swear just yesterday I watched a science video on recent ideas of dark matter that suggested that it was particles and not waves. Which is it? We don't know. Does it even exist? We don't know. This is why I enjoy this channel so much. Sabine calls it like it is, and not like some who claim that dark matter has been proven to exist.
I have been wondering lately; how many photons are traveling through intergalactic space. Every star in every galaxy is literally pouring photon energy into space and given that E=mc^2, all those photons are equivalent to a certain amount of mass. How can a real scientist simply ignore all of that matter/energy that is agglomerating in deep space? The number of photons traveling through space is increasing _all_ the time. The number _never_ goes down. They call it 'dark matter/energy' but in fact, it is photons. I take the view that science died on 9/11 after a protracted illness and Sabine is almost unique in the sense that she possesses the qualities of a true scientist despite the demise of science.

When dealing with spheres, using radius often confuses people greatly due to the Pi*r-cubed ratio. Adding the volume is more helpful. A core with 1800km radius has a volume of 2.44×10^10 cubic km. A core with 3600km radius has a volume of 1.95×10^11cubic km! So, while the radius is double for Earth, the volume is 8 times larger.
Could someone explain how exactly you can increase or decrease the connectivity of a bunch of tiny wires splatted onto a substrate? Did they go in and manually weld or disintegrate the "good" and "bad" connections with a scanning electron beam or something? is there some way to do it with cleverly modulated end-to-end electrical pulses?
Hi, thanks for such a great question. I'm one of the authors of the paper. It's quite difficult to change the connectivity of the network in hardware, but we built simulations to emulate what happens when you change the connectivity. We did this in a previous paper, not the current study. What we DID do in this study was change the conductivity of the wires (meaning we controlled how much current can flow through different regions) by increasing or decreasing voltages of "drain" electrodes. For example, if we want more current to flow towards the bottom right of the network, we decrease the voltage of the electrode in the bottom right, and increase the voltage in the top right. I hope this makes sense :)
Great content, as usual, but were you wiping the video up and down more than usual? It's a nice transition effect between sections, but overusing it within a section can make some of your audience feel queasy. I'd love to know more about how they manage the connections in the wire networks, and laughed out loud at your summary of the quantum computer paper 🙂
Theia did it!! It brought us our moon, our ocean, rotational spin rate, plate tectonics, the core dynamo, and resulting magnetosphere. Theia was like Ceres, in that it had water ice. Smashing into Earth the way it did created a lot.
