I've seen stars that move in the sky at a noticeable speed and at the end, disappear. What could be these moving objects, maybe satellites or stars? Maybe someone have seen these kind of movement and knows what it is?

If we are able to travel back in time on day, which way would it happen? The Bill and Ted version, where when we go back in time to do something, it's results were already seen in the future, even before we actually did go back in time; or the Back to the Future version, where when we go back in time, anything we do will cause us to return to a different future.

There is no formula (hence the reason they are prime), but there is a way to mathematically figure it out. Tell me your answers and how you figured them out. The best "formual" gets the points.
Hint: Stephen King wrote about it in one of teh Gunslinger Series books.
