I just can’t put my head around the fact that gravity isn’t just a force
EDIT : I now get how it gets stretched and how it’s comparable to putting a ball on a stretchy piece of fabric and everything but why is *gravity* comparable to that. I guess my new question is what is gravity ? 🙂 and how can weight affect it ?
In: Physics
I recommend this General Relativity video (it’s available in French too):
[A new way to visualize General Relativity](https://www.youtube.com/watch?v=wrwgIjBUYVc)
It will explain why the “stretchy piece of fabric” visualization is actually pretty bad (as it misses the time stretching, and it explain gravity with… gravity) and propose a few different visualizations.
Unfortunately, I can’t really explain the content of the video with text, here, as this is about visualizations… The only thing is that in reality, when we “fall” we actually convert our time-speed into space-speed (if one were able to see space-time itself).
