What is Curved Spacetime? Curvature Visually Explained!

🚀 When people say the universe is curved, what do they actually mean? I explain the concept of Curvature in two parts, and end off with a concrete example that shows that our spacetime is indeed curved.

This video is simply mind bending. No one can explain such complex concepts in simple terms. I watched it twice to comprehend it better. Great job.

[quantisedspace]

Thanks. This is the best explanation of curvature that I've ever seen. The whole 'space is expanding into what?' question is becoming clearer to me, as a consequence of this.

[akm_io]

This was explained so well! Can’t wait for more videos from you 😄

The best explanation of space-time curvature through graphics.

[icebeartwo]

This was really an amazing video, I am happy for the growth of this channel. Keep going!

[adiblokhandwala]

This video is amazing, hope you'll continue teaching complex concepts by breaking it into simple chunks like this

[cerealpuffsalmomd]

Good visuals, they really help! Looking forward to your next topic!

[Ninnanannetristi]

Great! Despite my mathematics low knowledge, I finally understood what Riemann tensors are. Beautiful and clear graphics and exposition. Thanks!

[TheJara]

oh my God you are back again!!! a beautiful presentation superbly explained math...Please keep posting your fantastic videos.

[imscience]

This is a great visual explanation. I have been learning GR on my own for the last many years and have seen a lot of explanatory videos on the topic. But this video is better than them all. Thank you and hope to see more such videos in the channel.

I've Subscribed... on the content of one video!! Now that's the first for me.... well done!!!

[robbatayaki]

I usually dont subscribe when new channel. But here I did. Finally a visual explanation of tensor !

[faisalsheikh]

Incredible quality of content sir you are phenomenal keep it up❤

That was excellent!
I think we need to start using the phrase "aging towards" something. Because that's what falling really is, you just age towards the center of mass of the Earth, no forces applied.

wtf why this have only 300 views?? great video!

[wknz]

Really a great video with lovely explanations!

[lowerbound]

Thank you for trying to make the concept accessible!!

[MC-wgfm]

I like how you basically started explaining the concept from a two dimensional perspective and made sure to say how important it is to have a 3rd dimension to fold a the paper in and how you showed the difference be the sphere and cylinder in three dimensions and how important it was. But then just quickly glossed over the whole 4th dimension and had a 5th dimension with an X through it as if it wasn’t possible.

Amazing !! I finally understand how curved space-time works ; many thanks for this excellent explanation !

[gustavogarcia]

Great work, very simple to understand for someone like me that is an ignorant in maths.
