Time travel has fascinated us for over a century, leading to all sorts of speculation about it.

Wells’ vision, however entertaining, overlooked one major problem with time travel: even if you could move to a different when, establishing where that would be is staggeringly complex. The Earth is not stationary, indeed nothing in the Universe is. You would need to calculate precisely where in space you wanted to be at the time you wanted to be there. Suppose you just want to go back a week. It’s not just a matter of going back a week where you are now, because last week, where you are now was 11.25 million miles away.
