do physics professors still misunderstand Einstein?? i registered at this site just to ask this question: why do physics professors still talk about gravity in terms of "pulling"?? i download podcasts of physics courses at Yale, Berkeley, etc... yet i always hear these guys say things like, " all the mass in the earth is pulling us down, every atom, cumulatively." As though gravity is a force exerted by mass upon other masses, when Einstein told us (almost a century ago) that this isn't the proper way to think about it. the earth's mass doesn't have any direct effect on us at all, actually; mass distorts *space*, and it is more correct to speak of space 'pushing' us down rather than the earth is 'pulling' us. if someone could please chime in and explain why this is, i would be grateful. it frustrates me so much! i'm no physicist, but have a passive interest and learn what i can. when i hear professors speak this way, as if they are ignorant of some of the greatest developments in physics, i just delete it right away. i refuse to listen to Newtonian depictions of gravity.... im not a historian!! and if anyone knows of some good (and accurate!) literature or anything on iTunesU please let me know. as i said, im not a physicist and don't have the benefit of asking professors or colleagues. im on my own, yet want to understand anyway.
