In Zee's Gravity in a Nutshell P107, 13 lines from the bottom, for a sphere of radius a, should the curvature G be 1/(a^2) instead of a^2?

Yes, it seems that it is a misprint.

Thanks. Since we are on this book, I have another question: on page 306, lines 9 and 11 from the top, should B(t,r) and A(t,r) have square roots on them?

I believe so, yes. :smile:
 

Thread 'Euclidean geometry and gravity'

I asked a question here, probably over 15 years ago on entanglement and I appreciated the thoughtful answers I received back then. The intervening years haven't made me any more knowledgeable in physics, so forgive my naïveté ! If a have a piece of paper in an area of high gravity, lets say near a black hole, and I draw a triangle on this paper and 'measure' the angles of the triangle, will they add to 180 degrees? How about if I'm looking at this paper outside of the (reasonable)...

Thread 'Relativity of simultaneity in actuality'

I’m attaching two figures from the book, Basic concepts in relativity and QT, by Resnick and Halliday. They are describing the relativity of simultaneity from a theoretical pov, which I understand. Basically, the lightning strikes at AA’ and BB’ can be deemed simultaneous either in frame S, in which case they will not be simultaneous in frame S’, and vice versa. Only in one of the frames are the two events simultaneous, but not in both, and this claim of simultaneity can be done by either of...
