Lense and Thirring predicted it, quite early in the development of general relativity. Here's Thirring's paper on the topic. It's rather math heavy, so you're not comfortable with that, you're perhaps best just skipping to the last page with the discussion of centrifugal/coriolis forces.

Not quite sure what you mean here...

The experiment didn't prove that time is indeed an entity - perhaps the most obvious way to do it is if one goes in space and returns after 1000 years but he's still young, or he returns on earth and sees the most evolved creatures being the apes (though in this latter case he may wonder if a 3rd world war happened) of if a time portal would be created, but in this case, teleporting people in past may be very dangerous (a little event may have grave significances after 1000 years, and so, many people of the future would disappear)
By the way, doesn't the teleporting through time imply another "time"? i.e. the first time he traveled in that moment, the second time he teleported in that moment. And, for instance, if someone of the year 2500 would teleport in 2011 and appear on news everywhere and tell the world, should that happen now or after we reach 2500? (year 2500 when he is teleported, so that the universe would 're-start' from the year 2011)
Indeed, such paradoxes are the reason that most physicists think that time travel is not possible.
