You might not have learned anything new, but I am sure that many other people did.
There wasn't anything misleading. At the time of Newton many people did believe that gravity had an infinite speed.
The video clip is just one segment of the Elegant Universe movie. You need to watch the whole thing and give it a chance. The book is even better …
Agreed, but what's the point of learning something that's highly misleading?
(and of recommending it, when there's plenty of good material elsewhere?)
If it was infinite, would you still have "Einstein's gravity"?
yes, why not?
(it would breach special relativity, and causation, but the speed of gravity is not an essential feature either of general relativity or of Newtonian gravity)
IWhat determines the amount of curvature of space close to a large object. I have always assumed that a higher speed of light would mean less curvature and a lower speed would mean more. Ie. infinite speed of light implies no gravity???
