I'm not a physicist, but I like these things. Have question though. After a long talk with a friend,I'm having a hard time understanding why the universe isn't deterministic. So i spent the last 3 hours reading on hawking seminars and other stuff and i think got a question who'se answer will clarify me. I always thought that the universe was not probabilistic, but just very hard to perceive in it's true state. So, if we consider the EPR-paradox-explained-for-kids-experiment in which we take 2 balls, a red and a blue one and 2 people, mix the balls, make each of the guys choose a ball, not look at it and separate them by 5000 miles. Unless one of the guys looks at his ball, is each ball red and blue at once or is there a certain state of the universe, concerning that 2 balls, meaning that the color of each ball is predetermined, but just not known yet?
