What an amazing video.

Awesome video. Educational and entertaining! My only ask? Creating an app for AVP and I’ll sign up!

I think there is a mistake in this video. If we are changing the coordinate system for two different observers then the coordinates of two "events" must also be different for both observers.

Your channel needs more attention 😅 So much detail and things I’d never know whilst watching the other videos!

Well if light is what we see and we are moving at the speed of light then theoretically from our perspective time should freeze.

I don’t think anyone knows what the back hole looks like . Just like the planets were never been inside the atmosphere except Earth . We can only imagine and guess the outcome.

I like the 3d grid, but space-time does not flow.. sorta bothered me.

Let's show the love for each other and never give up on each other or are would or I kids much love

Thanks insightful

10:42 electron creates magnetic field due to its spin or its movement ?

There is a circularity in the visualization which makes it pretty meaningless, I fear! The visualization only serves to visualize gravity, it says nothing about what gravity is. If a massive (=heavy) object sits on a fabric, pushing it down into a hollow, then other objects slide down into that hollow, not because they are attracted to the massive object, but simply because gravity pulls everything to the lowest point. Unless you already have gravity, there is no reason for objects to seek the lowest point! So, you need gravity to explain gravity! Hence the explanation is circular!

Wow, this is explained so much better than any textbook I've ever read. Introductory textbooks present the basic information about electromagnetism (and many other things) as essentially just useless bits of trivia that need to be memorized. Like the textbook is just a laundry list of things that exist, with no holistic, big-picture explanation of how they fit together or how they arise. Chemistry is the absolute worst in this department, where for your entire primary and secondary education, the periodic table and fundamental forces are conceived as just pure abstractions, symbols in a table, except for the occasional practical lab demonstration of reactions that, while interesting, are usually detached from the rest of the pedagogical flow and therefore don't assist in learning. But physics is pretty bad too. Although I understood the basic concepts they wanted me to get, it was all purely abstract in my mind, and I had little sense of how most of the ideas related to each other, so it largely did not change the way I looked at the natural world. It was just a collection of unrelated mnemonics, basically. And my high school was ranked around 300 in the US, so it can't be blamed on a particularly bad school. I mean, I guess I understand why they might do it this way for a high school physics class. Perhaps they think kids are too stupid to understand a bottom-up theory. But in reality, what stops most kids (at least not intellectually disabled kids) from learning is not an inability to grasp complex ideas, but a lack of interest rooted in the fact that the material is presented in such a boring way, where you might as well be reading a dictionary in a foreign language. They should be telling one _story_ that all fits together coherently, since that's how humans have adapted to learn things. From stories recounted by your parents, passed down from generation to generation, from long before written history. One of the most thrilling things about learning science is when you see the connections between things, and suddenly a lightbulb goes off and you're able to piece together the little bits of information you've been digesting into a web that actually explains something. But if those connections aren't made apparent to you quickly, not many people are going to have the patience to keep swallowing disconnected bits of random information about things like electrons, which are completely abstract from the human point of view. You have to be really comfortable with abstraction to put up with that for long enough that you can piece together a coherent, holistic understanding of electromagnetism all by yourself, and that's a tiny minority of students. So of course the vast majority of people forget this stuff, even though many of them (like myself) end up working in fields that require the same cognitive abilities that theoretically help someone understand physics. I'm a software engineer and certainly more than capable of complex, abstract thought, but I forgot so much of my physics education from school because it was just a bunch of trivia. It was not a coherent theory that I really _felt_ in my mind. I relearned it all as an adult, basically from the ground up, and now it _does_ inform the way I look at the natural world on a day-to-day basis. It's unfortunate that it took so long, because even back then, I was actually fascinated by physics and especially cosmology. I wanted to know much more, but my inability to really develop a robust understanding of fundamentals like electromagnetism, orbitals, and physical fields - due largely to having a purely abstract, trivial memory of these subjects, rather than a practical "story" reflecting real knowledge - made it difficult to learn more advanced subjects. So I moved on to the more practical (yet, in a way, more abstract) discipline of computer science. In retrospect it seems so silly. So much of my direction in life was decided by the way information was initially presented to me. Not that it's too late for me to get into cosmology, but I'd be leaving a lot behind to enter a much less lucrative field, and most of the computer science learning I invested so much time in would go to waste. So I don't think I'll ever do that, but I do think examples like mine are illustrative, and they should encourage us to reconsider how we teach physics at the primary/secondary level. Leaving a bad first impression for a subject is really disastrous. Think of the number of potential physicists we're losing, just because they never have that a-ha moment that makes you fall in love with a subject, when they easily could have if their first physics class presented them with a coherent story of something that isn't already obvious (like kinematics) to anyone with the innate cognitive abilities required to ever become a physicist.

is that a geometry dash reference?!?!??? 😱😱😱😱😱😱😱😱😱😱😱😱

..but I don't think/believe this is accurate...

i have one question, if you went from point A to point B at 50% the speed of light and cameback, considering point A and point B are 1 lightyear apart, the trip would last 2 year for you, but for someone at point A you would take much more time to comeback. therefore, from their perspective, you would have travelled at a much lower speed than you actually travelled, which means that from their perspective the faster you go, the longer it takes for you to comeback? like there is an ideal speed where if you go any faster in relative to a person, they will perceive you as going slower. also why doesn't this apply to light? wouldn't light seem still from our perpective? since it would take infinite time for it to reach our eyes, and if time gets dilated to infinite at light speed, then how come light have a measurable velocity? shouldn't it have infinity velocity? but if that was the case then we would be able to see the whole universe, but actually not because light would take forever to reach us, please someone help, i can't make sense of it.

nah...i'm gonna find a way to achieve interstellar travel without any effect of time dilation occurring.

awesome👍🏻🤩

1:27 *Muse starts playing*

I really HAVE to live long enough for scientists find out where the singularity leads to, how the universe actually began + will end, and if we live in a simulation. Can someone please help?

Now rewatch this and think what similarities it has with gravity

Loved that explanation, and how space time is depicted. It is better than a rubber mat, where gravity is explained by gravity.

Thanks

I like the Vangelis touch in the background music. Great video!

I accidentally had this other low-fi ambient synth video playing at the same time as this video and I think it enhanced it 1000% kzfaq.info/get/bejne/gNqontuiuJyuf5c.html

This is about the best video on electromagnetic waves I've seen. Well done!

It's been said, but wow. This visualisation is just superb.

this is class, trading acceleration in space for movement in time, if i got it right, explains alot of what i didnt get before

Excellent made. But it is total bs. Sorry.

Why is it always 45 degrees? And why does the light cone only tilt 45 degrees at the event horizon, not more or less?

Love this. Very well done. 👍🏻

DNA is great for biology - and it is fundamental to evolution - which is something that is very bad indeed for a storage system whose purpose is perpetual error-free storage. This makes DNA a silly thing to encode information on, unless you are alive - in which case, groovy! DNA is tremendously difficult to preserve, and its access time is frankly, terrible. There will be some amazing developments with DNA in the future - but not for data storage in computers. One of the great things about the advent of AI will be to greatly assist humans in managing and working with large data sets. And in this way, build up a lot of metadata, which makes the data actually useful.

Polarised sunglasses are awesome. They allow us to almost entirely eliminate glare from reflections from water. They affectively upgrade our vision, making you slightly better sighted than unenhanced humans. I have four pairs. Pretty soon artificial hearing will be superior to normal human hearing - and in many ways. Bring it on!

You can't see space time fabric for ever what Einstein missed to explain reality actually space time fabric never existed ever in place of stf there exists another kind of fabric made up of prime particle and gravitational force acts through this kind of net or fabric invented by me has kept is name as gravitational quantum net this is brand new invention made by me requires to be explained through application of a new language known as language of quantum chemistry so the science of quantum chemistry emerges itself as new frontier of science that explains quantum phenomenon in better way what Einstein could not explain in his life time but he shought of it I have fulfilled his expectation by developing new theory known as quark hypothesis search this article in internet u will find the true answer also find where Albert Einstein was failed and wrong information delivered space time fabric exists my calculations are not more hard to understand any lay man can understand me d j chatterjee most humbly stating don't be confused of wrong statement misconceptionaly delivered by Einstein as he is the greatest scientist ever down on earth we all are grately obliged by his unparallel work thank to God for his contribution me from Delhi india

The only phenomenon that can defy the singularity of a black hole - camera man

Thanks for insightful information

You would not see anything because you would be dead. You would have to have no mass to travel at light speed

This moment of time was spent well.

Toilet Bowl Model fo Gravity - you overthought it. if spacetime is curved then using the Cavendish Experiment with the addition of a laser beam should be able to demonstrate that curved spacetime can deflect a laser beam. Mass distorts time, not space. Otherwise you could use the cavendish experiment to prove that gravity is a curvature of spacetime. See if you can use mass to deflect a laser beam, I DARES YA! Once you do, I'll believe in he Toilet Bowl Model of Gravity. Until then, FLUSH TWICE, its a long way to the nearest black hole. It's a wave function and an analog of current, ground and waves, but not electrical. BTW - light creates spacetime, so it has somewhere to go. Light has no where to go in a black hole - no space. Math and CGI can make things that cannot be real.

11:54 again we would experience NOTHING, not even one moment-it would be instantanious

0:01We would see NOTHING and experience NOTHING, we would experimce billion year as SAME MOMENT and I don't even need to watch it-its relativity itself so doesn't have sense

Perhaps humans are just (unwanted) bi-products of some cold-data storage left behind by some other being?

Fuck that shit

So basically, accelerating to near the speed of light we'd be traveling back in time and eventually reach the Big Bang?

Good lord another great video

Lovely, somehow I suspect you won't be hearing angelic music as your being spaghettified.

@6:40 I don't understand how the metric behaves at the center of the earth. It looks like some kind of "singularity", since everything is falling towards the center (so wouldn't the center have "infinite amount" of the spacetime fabric?). Could you explain this a little further?

Up is Tomorrow

well explained

10:01 by this logic shouldn't good conductors be better reflectors than bad conductors like glass?
