I heard you folks!

What do we see from the ship’s perspective?

Hint: We discover the second consequence of special relativity. (one more to go)

[kenpaget]

this guy is THE BEST, MOST CLEAR EXPLAINER, after 50 years of attending lecttures, reading hundreds of books. the guy has a gift... thank you so much

[jjones]

2 AP classes in high-school, and 4 years of high level mathematics in college, but the random guy I find on youtube explains this better than any teacher or professor I've ever had.

[longnamesaredumb]

I’ve watched several MIT and Harvard lectures on special relativity and this is the clearest explanation of time dilation I’ve ever seen.

hi people, i am from brazil. its amazing how your " level" of problem is trying to understand this really complicated topic. i want you people to understand, the reason why america is such a great country is because there are people in the comments trying to explaing to a 9 years old daughter about relativity. THIS is the reason, you guys get curious about something and try to investigate. That is what makes your society way more advanced than 3rd world countrys. Here, people are proud of being ignorant about congratulations to everyone who watched this video, i hope your life is full of blessing, please raise your children to be curious about the universe and ask questions. Never let your country become what is happening around the world.

😮 You taught me in 16 minutes something I wasn't able to understand after years of self-study! 👏👏👏🙌🙏

[MouadhCosmic]

Everybody who makes physics videos talk about time dilation and special relativity.. but no one explained it as intuitively and as simply as you did, I have stumbled upon time dilation equation many times and never seemed to understand where it came from... But now I can perfectly see it and make sense of it, keep up this beautiful work and I am deeply grateful for your efforts

[TechnooRam]

You have no idea how good you are at explaining stuff. Genius!

[Amidaegon]

They say there is always an Indian guy on YouTube with a tutorial for any topic. Now an Indian guy made the best tutorial for relativity. I guess we can see "how to build a time machine" tutorial soon from some Indian guy. Amazing job.

[mehrdadhassanabadi]

After 38 years finally someone came along to explain this phenomenon in an intuitive and understandable way. Thank you for finally making me understand what is going on! 🙏

[Rosetulippp]

Who want Mahesh to infinitely keep making videos?

[Poodleballin]

Wow. I have read countless Quora posts/comments, watched many YT vids, read science mags, articles, etc. and this FINALLY explained it to me. Only took like 40 years! Thanks so much for what you do.

[spdhegde]

Hands down the best explanation on the internet for this topic. Never been explained so simply yet so effectively.

[Cryptic]

My man. This was one of the most joyous videos I’ve ever watched on physics. Your joy is contagious and I love every second of it. Love the way you explain everything and your emotion behind it all.

[JohariW]

I've known about this since high school 20+ years ago, but this is actually the first time I've ever understood why. Thank you so much, you have truly enlightened me, and everything finally makes sense.

[YanivGorali]

I cant recall the number of videos on the subject and i never quite felt like i got it.
Thanks to you and your ability to communicate so well, i finally got it.
Keep up the great work!

[ponchogutz]

You are brilliant, not only because you understand what you explain, but because you got the amazing talent to explain it to us.

[Andrijko]

This guy is my absolute favorite science communicator.
Keep it up Mahesh!
If we had more professors as excited as him, to teach their respective subjects, kids would definitely be doing better in school.

[Mahesh_Shenoy]

I made a boo boo. The formula for the relativistic kinetic energy is WRONG at 0:10! But the concept is accurate and this doesn't affect the rest of the video. Sorry! Thanks Adrian for pointing that out.

[vpardude]

I stumbled upon this video going down the interstellar rabbit hole. Only one word can describe this. WOW!! Explained so much in a simple way. ❤
