A new way to visualize General Relativity

But under this point of view there's no force at all. Gravity doesn't exert a force on you, the movement under gravity is purely inertial. I know this is bonkers. Here's the video that made me finally understand it ▶ this video ( link is another good video from the same author)

scienceclic also comes in an english edition. hands down the best visualization of general relativity I've seen. ▶ this video

Science Asylum is great, but I dislike the 90s educational show presentation format. An absolute gem I've stumbled across is ScienceClic: link They have amazing presentations on Relativity, my favorite being: "A new way to visualize General Relativity" - ▶ this video "Hawking Radiation" - link Another, while heavier and less accessible channel is Physics Explained: link These are closer like lectures, but I enjoy them because they go into the histories of some of these experiments; and what the prevailing wisdom was around the time the experiments were performed: "What is the Ultraviolet Catastrophe?" - link

This video really cleared up a lot of misunderstandings for me: ▶ this video I had never visualized it this way in my head before, and it all makes a lot more sense now. Highly recommend!

Very nice, fairly efficient too. I don't like the explicit split of Newtonian and relativistic gravity, this is often how it's presented in educational content, but it creates too much confusion; for instance it gives the illusion that they are somehow separate theories even though Newtonian gravity is a limiting case of Einsteinian gravity when v << c and gravitational fields are weak (see Poissons eq for Newtons gravitational potential. Lastly, you should consider rendering spacetime similar to Alessandro Roussels spacetime visualization ▶ this video ; probably the best and most innovative one I've seen.

Sure, no doubt, a video can sometimes make things much clearer. A great example (to me) is this [1] for example. I had understood from the old illustrations that I was supposed to imagine something like that, but video makes it incredibly clear. The actual net impact of screens in classrooms, however, appears to me to be extremely negative, and I think learning outcomes bear that out. [1] ▶ this video

The rubber sheet analogy is criticised for this exact reason. Here’s a different visualisation that starts with what’s wrong with the rubber sheet: ▶ this video

That's linked at the bottom of the article. Another good video to visualize GR is this by ScienceClic: ▶ this video
