It is interesting to me too. I used to think that the prophets were just predicting things which were already set to happen. Reading some of the New Testament I get the idea that God had them predict what would happen then he made it happen.
I have never really understood Einstein except generally. I do got the impression that he was seeking the one explanation which would explain everything. I guess it is another was of saying God but he must have been looking for a physical explanation.
I sometimes wonder if time may be like a movie. Instead of 32 frames per second, the Universe is composed of trillions of frames per second or even more. Someone who could control any or many frames could do about anything.
Einstein was an expert in his particular field. Predicting the future itself represents a sort of time travel which no scientist will seriously say is possible. What is impossible for a man, however, is what? Possible for God. That is how a rich man is able to go through the eye of a needle to reach heaven. Time travel is another interesting subject, which although I believe to be impossible (at least for us) I possess way too much information.
