The Relationship Between General Relativity and Spacetime
I think that people who do foundations of quantum mechanics generally don't think too much about general relativity and spacetime, or if they are experts in it. But I do think that that's something people should take more seriously. And this is the effect of gravity on quantum mechanics, not of quantum mechanics on gravity. You're just looking at experiments which are on the verge of being done or being tried even now. One of the latest ideas is using Bose-Einstein condensates. These are very, very quantum mechanical states, very, very cold, almost absolute zero. And you could put them in super positions of two places at once and maybe see what happens. It's experiment
