I really enjoy Ted-Ed videos and I dont underestimate the time and effort spent on this video, but this explanation really missed the mark.
Why is when and where the same thing as posited in the beginning.
You separate the animation into frames the first question in my head is: why? Why flip them?
Is the world a stack of frames being flipped? At what speed is it being flipped? Who, what is flipping it?
I really dont get the comparison or what is the comparison that is being made?
Why are we doing a spacetime diagram in the first place?
The only thing I understand of the video is that asking when and where is the same thing. Why? I dont know.

Newton says that gravity is instantaneous but Einstein says that the speed of light is the speed limit of the universe so gravity can't be instantaneous.
I could not get any of that so I want to ask those with knowledge that what does Newton mean by gravity is instantaneous, how does Einstein know that the speed of light is the speed limit of the universe and how are time and gravity related?
Thanks in advance for the replies.

If I'm not mistaken, the frog's vision has a poor frame speed - it would probably be, as far as I understood, more like seeing an illustrated book, than a sort of a continuous movie.
Ain't that funny! I mean, think about it. The possibilities, the implications. That's really interesting.

Just listen to me, I'm not kidding.
Last night I was wondering about space-time while sleeping and the next day i got this video on my recommendation. I have never searched anything related to space time ever in youtube or in Google.

Time in space is different in space because its a fourth dimension as its not relative to mass its its own entity. Mass & gravity bends space, so because the mass is moving its moving fast its moving slower through time.

Straight up this is not helpful I already understand the subject just want to see if the theory's have been changed I guess if U don't get it don't watch this or U won't get the words Pannell and slide out of your head

I want so hard to understand! I need to understand! But even when broken down like this into bite-sized chunks, my brain struggles. But alas! I will persevere!

Einstein created the idea of Space-Time just to confuse us.
For example a room has space and the clock shows time, the two are very different.
