Interstellar Travel

interstellar travel would probably involve even more forces acting on a spaceship to cause it to deviate from its course. These influences would have to be understood and modelled mathematically if you were going navigate accurately. Will smith suggests the possibility of using pulsars. Polsars are highly magnetized stars that spin around very fast, shooting out beams of electromagnetic radiation out of their magnetic poles. The intervals of these pulses can be used to identify what pulse are you're looking at.
