Do you think that what you feel in your heart and hear in your mind at times, could be "you" communicating with yourself from future? Like... before you speak you hear an answer in your head? Or you sense something that otherwise, is hard to explain how you did it? I've had many of these over my life...
This Physicist, and author is saying time travel is possible, and affirming Einstein. To my knowledge, he isn't saying the above... that's my fascination.
Props to @rolandculthbert for leading me to this exploration...
