Technically, if the article I read a few months ago is true, we all "time travel" and see the past every second of our lives.
According to the article when we look at an object or person we are really looking at what they looked like milliseconds ago because it takes light "time" to travel from the person/object to our eyes and for our brains to process it therefore when we "see" something it really is seeing what it was like in the past.
That's amazingly brilliant...for any 101 bio course from 50 years ago.
