From TIME LINE By Michael Crichton

“The very concept of time travel does not make sense, since time does not flow. The fact that we think time passes is just an accident of our nervous system–of the way things look to us. In reality time doesn’t pass; we pass.Time itself is invariant. It just is. Therefore past, present and future aren’t seperate locations, the way New york and Paris are seperate locations.And since it isn’t a location, you can’t travel to it.”

“..Remember, within the multiverse, the universes are constantly splitting, which means that many other universes are very similar to ours. And it is the similar ones that interact. Each time we make a beam of light in our universe, beams of light are simultaneously made in many similar universes, and the photons from other universes interfere with the photons in our universe and produce the pattern we see.”

“..Therefore some universes exist at an earlier time?
“Yes. Actually, since they are in infinite in number, the universes exist in all earlier times.
