Rocket flies from Earth to a star, 4.5 light years away, at 8.66C (the actual numbers are irrelavent, so they might be wrong). When the rocket gets up to speed, instantly, the distance between earth and the star contracts to about 2.3 light years. So the journey only takes about 3 years. Bargain.(adsbygoogle = window.adsbygoogle || []).push({});

Then, when the rocket reaches the star and stops, the distance ebtween the star and Earth expands back to normal size - 4.5 light years.

So, the rocket has travelled 4.5 light years in only 3 years. I.e. faster than the speed of light.

This is what i dont understand. Any help would be much appreciated.

Thanks : )
