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.

I'm a professional chemist, degree and all, a genuine science geek, I'm in my 40's, and TODAY is the day I finally grasp this concept. Thank you.
@mehrdadhassanabadi3391
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! 🙏
@VinayMusicCorner
I cannot explain how good this video is. In the history of YouTube viewing, I have never ever come across such an amazing explanation such a simple way to explain the complex thing. Probably even a noble prize winner would not explain so clearly. Hats off to your teaching skills, and you have hit the bulls eye is animations and everything. Wish I could meet you some day. Brilliant brilliant brilliant.
@TechnooRam
You have no idea how good you are at explaining stuff. Genius!
@kenpaget2895
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
@biosteamstudio
Best explanation of Time Dilation and the speed limit I've encountered. But above all, I got quite emotional with your enthusiasm and teaching skills. It's as if you are discovering the phenomenon together with the student and getting blown away when you understand it. It is so inspiring.

Another explanation for this question is:
When we travel at any speed there is a relative increase in mass. It can be calculated by an equation similar to what he explained about time dilation equation.
M
M ' = ----------------------
√{ 1- (V²÷C²)}
So if we travel at "c" the relative mass will be ♾️
To accelerate an object with infinite mass require infinite Energy which is not possible.
Detailed explanation
At 99% c - Relative mass(M ') is 7.1 times M
At 99.9% c - M ' is 22.4×M
At 99.99% c - M ' is 70.7×M
At 99.999% c - M ' is 223.6×M
At 99.9999% c - M ' is 707.1×M
At 99.99999% c - M ' is 2236×M
So its clear from the above results that as we are approaching c the mass of the space ship increases unimaginably.
To accelerate a ship from 99.9999% to 99.99999% would require very high energy as mass increase from 707 times to 2236 times.
In this way mass increases and increases and close to light speed the mass will be very very large. And to accelerate such a heavy object further requires infinite energy. Which is not possible. Hence anything which has mass can never travel at light speed. Anything which doesn't have mass could.
And why does mass increase when something move?
To move an object, it should have Kinetic energy.
This kinetic energy will be converted to mass as of the equation
E=MC²
It even happen in our day to day life when we travel with some velocity our mass increases but its too negligible.
@MouadhCosmic93
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
@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.
@jjones503
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.
@retropenguin9019
I'm a psychologist but have always had a crush for math and science and just stumbled with this video and wow this was so nurturing. I cannot thank you enough for this explanation. I've thought about this topic for a bit while waiting in hospitals or banks but you just gave me the pieces to make everything CLICK. I'm Grateful!!!
@Major.Tom.1973
😮 You taught me in 16 minutes something I wasn't able to understand after years of self-study! 👏👏👏🙌🙏
@louischen1280
I think the fact he's explaining this to you, eye to eye and never cuts away or edits away, helps a big ton. The rigid logic becomes more relatable especially when he infuses the lesson with emotion. Great educator!
@Cryptic808
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.
@GreaseAndGravel
Best explanation ever!!! Thank you. I still struggle to understand what the person in the rocket ship will feel when accelerating at 1000km/s/s since time will feel normal in there. But totally see it from outside that it will take forever to keep increasing speed.
@Scritley
With no exaggeration, this man and his videos should be in every high school and college classroom. I've struggled with this topic for years and in two 15-20 minute videos, he clearly and concisely explains time and distance dilation in a way that someone like me, with a great interest in astronomy/physics/special relativity but who does not possess a degree in these areas, can understand. Furthermore, the way he unfolds the narrative, like a building conversation with Einstein and with his contagious excitement of the topic and of finally understanding it sprinkled in, completely amplifies the greatness here. Well done! You've earned a life-long subscriber.
@nguyentrananhnguyen7900
people usually only talk about going faster than light, but hardly anyone talks about time dilation you are the first one to help me understand it, thank you
@Rosetulippp
Who want Mahesh to infinitely keep making videos?
