Wow, I can see why this hard to grasp :)
Wouldn't this mean that the pilot in his frame of reference crossed 4 light years in 0.57 years? In essence traveled faster than light?
I am aware that during his trip when he looks out the window he will see light racing away from him at C...
I didn't think the precise numbers are important to the idea.
Really? I thought the whole idea of relativity was that a time passes more slowly for you if your traveling closer to light speed. The person in the cockpit moving at 0.99 C would expierience 4 years and travel ~ 4 light years but...
Okay, let's say 2 ships start a voyage to Alpha Centauri, about 4 light years away. Ship A travels at 0.99 x C and reaches Alpha Centauri but because of time dilation let's say 100 years pass on Earth. Ship B travels at 0.1 x C and gets to Alpha Centauri in about 40 years according to an Earth...
