Great video, Thank you. So it is no longer a current theory that half of entangled particle pair falls into BH and other "flies away" into the cosmos? I wish the old videos with that theory would get a disclaimer by now if it is an obsolete notion. If it is not an obsolete notion then I don't know why this video seemed to think we had come beyond that now.
In light of recent research suggesting gravity is emergent from a quantum entropic force, I do not believe this view presented in the video is correct. Instead I think the presentation is highly confused, and misleading. Did we have experimental evidence to support this view? It clearly does not agree with Newtonian gravity model. I think we need to be careful about what information is broadcast, esp if it is not accurate. Already physics has many issues regarding the accuracy of orthodoxical views and "mainstream" promulgations. Would you care to cover any of these? The 100 Greatest Lies in Physics by Rey Flemming would be a good start. If you did not agree with any of those, how about addressing the Crisis in Cosmology, and issues raised by the many detractors of the Standard Model. Thank you.
The only thing moving at the speed of light is your consciousness. The matter says put. After all, the universe is a block universe, where the past, present and future are all frozen in place forever. When you see something around you “moving”, you’re really seeing new images of the thing. Like in a video where you see image after image and each image is a new frame in the video.
Wow, it's the first time I understand why the discovery of gravitational waves is so immensly important. Thank you for explaining these things so easily and make simple minds like me comprehend and appriciate the work of scienstists.
Zombies are a natural demon, as all life produces offspring that are insects grown in layers of bodily productions so in unhealthy circumstances if we die a registered death if the insects are also formed of our sickness insects will grow in our dead corpses and will have the capacity to functional move because the insects are imprinted with the structure definition of our lifelike forms = we do not get parasites from our offspring. Life actually does not load any other life we are not dying parasites to each other
The more methods or techniques humans devise that could possibly destroy ourselves or our planet, the more likely it is that this will happen. Its almost inevitable we will destroy ourselves if nature doesnt do it first. Same could be said for any civilization. Intelligence could be its own filter.
I wonder how this is viewed from quantum mechanics? The air is in gaesous form and should have clear emission lines. How come all of the light is scattered and why blue so much more?
Gravity is just a sort of function of space over time, but it's not exactly the same as velocity. And matter warps space, and therefore time, making both space and time less. Without any initial velocity, you still move faster over the smaller distances and less time in proximity to the warping of space that matter creates, and that's gravity. Gravity is literally a space warp, just like a Star Trek warp engine, only we take it for granted because it's perfectly natural!
I address this in the video. Standard fusion gets you up to the iron/nickel area on the periodic table and it skips a bunch of elements on the way. Other processes fill in the gaps.
Finally rewatched this wonderful series, thanks again for sharing! Speaking of SR, I was wondering if you have any undergraduate/graduate book to recommend on the topic that also avoid critical flaws/misconceptions like "relativistic mass" and "the twin paradox can't be solved in SR" (and related), thanks!
It's better to think of the "flow" as a _shockwave_ instead of a flow. The electrons are like the water molecules and the water is the electric field... but instead of water flowing through a pipe, the pipe's ends are sealed and the water is mostly stationary (while also somehow extending outside the walls of the pipe, but that's a whole other mind-boggle). Then you tap one end of the pipe and that'll send a shockwave through the water from one end to the other. A ripple of waves that moves THROUGH the water, moving each molecule of the water slightly, but the WAVE is what moves fast from one end to the other, dissipating in strength along the way. That's exactly how electricity behaves. Direct Current is like tapping repeatedly and sending uniform shockwaves again and again in one direction... current being how frequently you're hitting it, with voltage being how hard you hit it with each tap to create bigger or smaller waves. Alternating Current is like switching back and forth between tapping and sucking a little to create a ripple of suction instead of a forward pulse. It pulls the water back a little bit in a wave of suction that would travel forwards through the pipe, pulling the water molecules backwards a bit along the way, instead of pushing them forward a bit. Do that back and forth 50 or 60 times a second and the motion creates more energy, aka bigger waves, by jarring the water back and forth really fast. The waves get bigger more easily this way than if you try to do it by pushing it in one direction repeatedly. With DC, you have to tap REALLY hard on one end to get the waves to stay big by the time they get to the other end of the pipe. But with AC, you can just shake it back and forth with relative ease to get big waves happening at the other end.
You're thinking of this as a stationary system. It isn't stationary. The forces aren't supposed to cancel out. They're just supposed to result in an orbital period that's the same as Earth's.
it’s just a math symbol we use for ease. it’s a concept just the way a line is a concept. there is no physical law of nature that says it has to exist. we just have these easy math symbols to work with. IF i were to program an AI to find universal laws of nature it would never discover this human abstraction of Pi, but rather an unwieldy calculation out to the 64th bit.
The argument in the hyperbolic cosine isn't an angle. It's called "rapidity." I have a video about that: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-vPi1lyAx4ws.html but what matters is that, if you're using an angle in degrees or radians or whatever, then you have to use regular cosine. (It's sloppy math, but it gets the job done.)
You are correct that we don't know why, but "why" is a question that's _rarely_ answered by science (at least not without creating more why question in the process). "Why does mass curve spacetime?" is an unanswered question on the front line of physics.
2:50 The Big Bang was uniform for a long time on human scales… but it was really only uniform during the period of intense heat that a c4 explosion would be uniform for, but because it is a bigger mass compared to explosion size, it stays hot and uniform for longer. It became turbulent when stars and galaxies formed.
Nick, this is cool, this makes more sense than whatever they told me in highschool chemistry. But I still don't get what's the nature of the attraction in first place, how does the bond work. What does it even mean to share an electron? And why is that an attraction? As a suggestion, could you make a new video explaining the bond from the point of view of quantum mechanics? somehow at the level of your excellent atomic orbital video. Also, how do ions happen?
As you pointed out, this is all governed by quantum mechanics, so it's inherently probabilistic. "Sharing an electron" just means there's a non-zero probability of finding it on either atom _if it were to localize,_ but electrons spend the majority of their time un-localized. I would love to do a whole video about this. I've honestly wanted to for a while. I've just never gotten around to it.
@@ScienceAsylum thanks! I got into a rabbit hole of molecular orbital theory and other stuff. I guess answer to my questions is mostly just math. For example: Sharing an electron makes the whole system to have less energy and hence that's gonna happen. There's no underlying more fundamental dynamics to it.
In a glass plant, making soda bottles, approximately 1,300,000 a day, this is how the bottles are checked to ensure they are properly annealed. 😉 40 years ago. Remove the polarizing filter on the front of an LCD monitor and the screen will always look white….. until you put on a pair of polarizing sunglasses….. and magically you can see the image, but nobody else can, unless they are wearing polarizing sunglasses as well.
