Last night, Jim Al-Khalili gave the clearest explanation of space-time I’ve ever heard, followed by totally destroying my understanding of gravity.
I think I’m up to about 10% understanding of space-time now. I’d love to talk to anyone that gets this stuff better than me. I liked the beetle on a log analogy and I think it’s helped me slightly to understanding something else I read recently. Can space-time be ‘visualised’ or is it an entirely mathematical idea that can only be hinted at, via models with a reduced number of dimensions?
Jim also screwed up a software release so that’s well worth seeing
