I myself believe that there will one day be time travel because when we find that something isn't forbidden by the over-arching laws of physics we usually eventually find a technological way of doing it.

Time travel may be achieved one day, or it may not. But if it is, it should not require any fundamental change in world-view, at least for those who broadly share the world view I am presenting in this book.

The bottom line is that time travel is allowed by the laws of physics.

If you see an antimatter version of yourself running towards you, think twice before embracing.

They might go for one fewer day on their trip, but they will still travel.
