To clarify: In order for two observers to measure the passage of time and confidently compare those measurements, they must share _two_ events (the starting of the clocks _and_ the stopping of the clocks). Without having both events in common, the comparison between the clocks is meaningless. On the space station, I'm traveling along the spacetime path that _maximizes_ the time between those events. All other paths, including Rocket Clone's, _must_ be shorter.

1 Dislike?! They probably tried to hit the "Like" button from someone else's coordinate system.

I have watched Matt O'dowd explain this exact same thing, and I could never really understand it. After watching this video, I understand it completely. Thank you! You have an incredible ability to simplify complex ideas. Honesty the best physics channel on youtube.

[jaiho]

This channel doesn't just make videos, you touch every aspect of the problem which i haven't seen in other channels

[admiralhyperspace]

Minutephysics didn't do justice to this paradox and I was searching for a better explanation.This one was much better.

[nachannachle]

This started as a confusing entangled mess and you weave it all out beautifully.

It's amazing how your brain manages to deconstruct every part of the paradox, anticipate the viewers' objections and give them a satisfactory answer.

I am a big fan of Fermi lab Dr Lincoln's use of equations to explain relativity. But you just beat everyone when it comes to manipulating the Space time diagrams!

[TheJohnblyth]

Truly wonderful. In decades of being bothered about explanations of this, this is the only accessible one that makes sense. Thank you!

[mattg]

this is the first time I feel I've ever properly understood this!! And boy have I read a number of explanations! PS your physics book is awesome :-)

[fakherhalim]

You are the first person I know who could ever clarify so brilliantly this age old "Paradox"! THANKS!

Yes -- it is caused by doing a simplistic math of just the time -- ignoring the core reason -- longer space-time path!
Remember, I was so frustrated after a third failed attempt of otherwise sensible professional that I almost pleaded you to jump into this subject and explain in your 100% articulate Style!

I always like the explanation when you plug in numbers in those equations, and actually draw the consequences! It removes any confusion!

[WalrusRiderEntertainment]

I think I need to watch this a few times for it to sink in... It is the "paradox" that does my head in too..

[admiralhyperspace]

This video should be a standard in special relativity textbooks.I mean Wow.

[scienceium]

This channel is so underrated !! i love it please share it on social media

[alexs]

Early enough to make a compliment. Been here since 5000 sub. glad that you got so many subscribers. You even answered a question of mine in an older video. Thank you and keep up !!!

[dansv]

I am always very impressed by how well you do your interaction with your clones.

[stanimirivanov]

Thanks for your videos. They give a courage for young people to get into science.

[hungdoan]

Omg! You are a life saver! I have been searching around the internet to find an answer to this question that satisfies me and this is by far the most satisfying! Time to sit down, roll up the sleeves, and do some Lorentz transformations myself!

[Kohwalter]

AT LAST!!! Finnally the twin paradox makes sense. Why can't everyone else explain the things like you do?! Thanks a lot (really)!!!

[sujandutta]

You really gave the explanation which I was looking for all these years!!!...Glad I watched this 😌

[dmullinsTWM]

Nick, you have a wonderful talent when it comes to explaining complex concepts, a natural teacher.
