*Correction:* On the spacetime diagram, the rocket shouldn't be firing it's thrusters. It should only do that if it's accelerating. Since it's not accelerating, its engine/thrusters should be off. My bad. Honestly, if that's the biggest mistake in this video, I think I did pretty well.
let's say we want to eliminate the effects of gravitational forces between objects on the diagram to preserve constant speed, so we use thrusters to compensate these and everything works ;)
Suggestion: Remake this entire video with your updated skillset and larger fanbase. Focus largely on the same subject matter but this time title it something like “Time travel is real, here’s how” or “Physics professor explains how time travel is real” I know you aren’t a professor but that title sounds like the catchy ones you see like “Linguist reacts to 5 movies” or whatever I think you know what I mean. I can’t figure out the best way to title you since Physicist is a hard weird to read /spell for most people.
This is probably one of the most comprehensive explanations of spacetime diagrams I've seen in a TH-cam video. I think it's safe to say you deserve to pat yourself on the back for this one, Nick :P
Flippy Sidee I thought he was going to metion how the speed of light is usually drawn 45° and is always stays that way even through a transformation. It's a pretty key point to understanding a lot of the weirdness.
First PBS Space Time wears a Science Asylum shirt, then Science Asylum wears a Kurzgesagt shirt. Here's hoping Kurzgesagt makes a PBS Space Time reference so the circle will be complete.

Add Veritasium and Minute Physics and it would complete the circle. (Ok, Isaac Arthur can be the center of the circle ... and there are countless channels I like too).
Great video. Minutephysics did a similar video but yours was easier to understand. Thanks for that. Also PBS Space Time wore your shirt during a video. Mad respect from the science community. Congrats.
Nehmo, I keep politics off this channel as much as I can. This channel is for science. Sometimes people make science political, so it's hard to avoid. For example, I once made a subtle jab at Fox News for regularly misrepresenting science, but I don't think the shady behavior of a "news" organization should reflect badly on half the U.S. population. I'll vote for who I vote for and you vote for whoever you want to vote for. As for product endorsements, full-disclosure is absolutely necessary for something like that. I make a point to mention sponsorships right at the beginning of the video. It's very important that I'm transparent about these things.
What I love about Relativity is that even though the consequences and predictions are not intuitive, it's just the logical consequence of a short list of things that must be true.
Your best video yet, and I think the best I've ever seen on the subject. I liked your split screen with each in their own reference. I'd love to see more of that in various conditions. Just plain excellent.
Best explanation yet, glad you, Lincoln, Space Time, Minute Physics and others, are going at this full speed to get it into normal conversation ! ! ! Even CRAZY conversation ! ! !
Nick, I know your channel for a while, but I just bought your book these days. I have to say, it’s just awesome how it explains stuff that most authors just through and expect you to get it (like most physics papers). I’m 16, but I love learning sr and gr, together with QFT, though I’m just regretful of not have found your work before and have to depend on continuously reading papers that just explain the subjects partially. Really, don’t you ever stop, because your work will certainly be useful for clearing people’s minds. Btw, I’m a huge fan
Absolutely love this channel. It makes science interesting again. Much better than doing the same calculations over and over again (And don't say that's relative, it's boring!!). Thanks for this and keepem commin' 🤟
Wow! This might be one of my favourite space-TIME lessons ever. Ten minutes of simplifying explanation and graphics that probably took you a very long time to think through and put together so well. Thank you for the effort. You have quite the knack... A Nick Knack - too bad there isn't a "paddy whack" to go with that.
This is crazy genius! I remember watching Gabe's video on PBS Spacetime a couple of years ago like 6 times to work my brain around what Relativity ACTUALLY was about. Had I seen your video then, I would have understood it all in like...9 mins! ;p
Now that this is finally intuitive to me, it bugs me that for the last 2 years it's been, "time moves slower the faster you go". Thank you so much! By the way, I love that you're wearing a Kurtzkesagt t-shirt!
I had bad times figuring out the notion « time » So I made a sidesearch and end up learning that the time DO NOT run in the same speed on land and in space... Then I understood it all... my mind was blowned🤯...(fast-fast!) So thanks to you and your simplified version:)
You are amazing. Learning can be so fun if we have teachers who are kind to students and are able explain things using simple examples. There is no need to kill oneself to understand concepts.
What jumped out at me, upon viewing the animated coordinate transformations, is that the translated space/time diagram intuitively looks like it can still have space and time still "really be" at 90 degrees to each other so long as we think of it as showing us a tilt 'backwards' into the third dimension. That's beautiful.
You are sincerely the best youtuber at expailning stuff everytime i get confused about something I jump to your channel wich is SOOOO underated thank you so much for making learning accessible to everyone ❤
Good job keeping the math to a minimum Nick. Equations are just TOOLS you need to use to DO something, like plot a rocket ship course. We're just sitting here looking for information on how the universe works. It's a waste of screen space to put them on the screen. Most people aren't scribbling them down, filling in the numbers, getting the solution (oo! it's 50.3! Now I have a deep understanding!!) Carefully chosen words, images and graphics are what can transfer the knowledge you have into most peoples minds.
In defense of math, you can get understanding from patterns in it, but yes those patterns need to be properly explained with words and visuals. If a teacher just throws an equations up and say "there ya go!" then it isn't going to communicate much.
@@ScienceAsylum I'm a little late here, but please keep the math. There are many channels that leave out the math to "simplify" but I find that with little explanation, math goes a long way in expanding one's conceptual understanding too. That's what i find unique about your videos. And, also the animations are fantastic.
@@nithyanagarathinam6215 For me, stuff like relativity requires an amount of maths understand coupled with worded explanation. Only maths will leave out the intuition
Briliant! That's the best explanation of relativity on the youtube. Man, you gotta make another version of this video (same topic, different wording, just to drive the point more. :) But this video already does make much sence. Thanks alot for the cartoons and diagram, it helps alot.
6:45 to 7 min was absolutely amazing. If you focus diagonally (on that time axis), then you see the lights blink at the same time. But if you focus on old regular vertical time axis, then the lights blink in an alternate way. Pretty awesome! Trying hard to get a grasp of Relativity myself.
Well, Nick, you really outdid yourself this time! I was aware of the raw facts, but your illustration of rule #5, at 5:50 nailed it home for me. Previous illustrations I’d seen changed the space-time paths and kept the coordinate system intact; your approach of changing the coordinate system around unchanging space-time paths really nailed for my intuition! Well done!
I had known this channel before I even stumbled over the mind boggling questions of how to understand the theory of relativity, time dilation (Twin Paradox), the perspective of light itself, etc. I've been searching all across the internet and have failed to find a comprehensible explanation. Until lord Algorithm brought me back here, to a video made over 3 years ago. This is the exact solution I have been looking for. Nick is right, the Space-Time Diagram is ultra helpful. Anything that can be visualized is WAY easier to understand. The math is to prove things, but the diagram is to understand things. He also presents all the rules before getting into the real deal, so the explanation is carefully constructed, hence solid and convincing. You're awesome, Nick! Thank you so much!
Rick you are an excellent educator. A lot of information is available on other channels, but I find your work to be easiest to understand, and fun too!
Love it, your best yet nick, time most excellently spent. ah. Rule number 7. Extra production time = quality videos. I jumped out of bed to watch this, or did the earth move away from me and I fell towards the laptop ?? Haha
I love this channel. Definitely under-subscribed. This is a very good video on Lorentz transformations. There is another good video about Lorentz transformations at minutephysics. These videos have really helped me understand general relativity.
Excellent video. PBS Space Time said that the speed of light is actually the speed of causality itself, which made me wonder, "Why does causality need to be constrained? Can't it affect everything instantly?". But then I realized that it can't because then, time would have no meaning. Since all causes would happen instantly, all resulting effects and then their effects would happen instantly as well. And as Einstein famously put it, everything would happen at once, making time nonexistent. The reason I think this is important is that this allows us to derive special relativity from fundamental logic instead of observations. In other words, this changes the answer of the question, "Why is special relativity the way it is?" from "Because that's what we observe" to "Because there's no other way for it to be". Sorry for the lengthy comment. Just felt like sharing some of my thoughts :)
The Science Asylum:Great point.I share your opinion too.Universe isn't complex for no reason.Its that apparent chaos that creates order.Only science can unravel this.Thats why I am also gonna become a physicist like Nick.☺️
From my point of reference, this video seems twice as long as most of your videos and took longer to get posted. Well done and certainly worth the wait and worth every second or minute or whatever measurement you prefer.
Back for my monthly view of this video, I would say the concepts in this are among the most essential to understand if you want any kind of understanding of the movement of planets and solar systems relative to galactic centres and other galaxies, top notch
Amazing explanation!! Thanks for making videos like these for people like me who are really interested to know the concepts but do not want to delve too deep into the maths to understand
Very good indeed, one of your best, hope i'm gonna have enough time to translate it into french, if it has not been done yet. Bravo, continuez comme ça.
Wow. I finally get how the space-time diagram works. I've seen it used on numerous occasions but this really cleared the whole thing up for me. I never had a problem with the math involved but this is exceptionally more intuitive.
Hi Nick.. thank you very much for your nice videos..I enjoy them all...I am a Mexican Citizen(70 years old), I am living in Mexico CD.. My name is Constantino ..once again thank you very much
You can do an Italian transform and in Italy "proprio" means both "proper" and "personal". The Trasformata di Lorenzo preserves both observers and nobody touches your spaghett.
It is like that in german. Proper means "richtig" ("correct"), BUT, the name for this time is completely different. We call it "Eigenzeit", which has no direct translation. Its more like "own time". As far as i know, in maths "eigenvalue" and "eigenvector" are common, too. So i dont know why they dont use it in relativity...
The coordinate transformation looks crazy similar to linear transformations by matrices. I seriously wondered why we needed linear transformations at all, and now I'm severely enlightened
@@ScienceAsylum And this takes me to another question... when I asked people where is the fourth spatial dimension, many said it's a mathematical impossibility. But considering non square matrices encode inter dimensional transformation, it is perfectly possible for any arbitrary number of dimensions to exist, ours being only a part of them. So, if we live in four or more dimensions, why cannot we perceive them? PS. I'm not bugging you😄...just asked...please don't be bothered😄
*Correction:* On the spacetime diagram, the rocket shouldn't be firing it's thrusters. It should only do that if it's accelerating. Since it's not accelerating, its engine/thrusters should be off. My bad. Honestly, if that's the biggest mistake in this video, I think I did pretty well.
No worries, that's just a Hollywood special effect we learned to filter long ago thanks to movies.
We're way past that 😸

Love how you flipped the coordinates from one observer’s view to the other! Great visual! Now relativity to me seems less crazy! 👍😀

9 minuite 46 second long science asylum video? What a day to be alive.
That's why it's been a month since my last video. This one demanded to be longer.
This video made me subscribe on Patreon. Absolutely the best explanation of all this otherwise confusing stuff I've ever seen.
You succeeded in explaining something difficult in an easily understandable way. Your best video to date.
Best explanation yet, glad you, Lincoln, Space Time, Minute Physics and others, are going at this full speed to get it into normal conversation ! ! ! Even CRAZY conversation ! ! !
What I like the best in Nic's vids, is how he seems to guess what were are thinking just at that specific moment and then answer it on the way :)
I love it that the reality of physics is MORE engaging than any fiction I've ever read. The cosmos rules!

I had bad times figuring out the notion « time »
So I made a sidesearch and end up learning that the time DO NOT run in the same speed on land and in space...

So thanks to you and your simplified version:)
OMG! Top video on relativity! Well done - now I'm waiting on the twins paradox and where the asymmetry arises! Then you covered it all!
You are amazing. Learning can be so fun if we have teachers who are kind to students and are able explain things using simple examples. There is no need to kill oneself to understand concepts.
I woulda been satisfied with a guide to space-time and relativity... BUT THE ULTIMATE GUIDE? YEAAAAAAA

Perhaps instead of proper time they should call it personal time
I agree. 100%.
