Can one ever be in the same place more than once?

However, there is a larger problem with space travel. Because your time machine needs to account for not only displacement through time but also the change in kinetic and potential energy states along your path in space-time, you have to make up the difference between your momentum vector at the start and end of your time travel. This means you have to apply a momentum change and the corresponding energy difference that exceeds the solar escape speed at the Earth’s orbit by an order of magnitude times the interval you transit (not accounting for any other relativistic effects). So, basically, your time machine also has to have sufficient impulse to be a credible interstellar spaceship. Mr. Fusion isn’t going to cut it. You need some kind of unholy energies that are only available by opening a portal and invoking the aid of one of the Great Old Ones, and we know where that path leads…

That’s why we have the Infinite Improbability Drive. Problem solved (in a very deus ex machina way).

I’ve forgotten the key, but I’ve got a couple of lids out in the car.

You might relative to the sun.

That’s pretty unlikely. The Earth does not travel in exactly the same path every year. And even if it did, the likelyhood of you crossing in your exact path is mighty slim.
