Subject: How does the movement of the sol system affect the

Hi, 
First take into consideration our solar system is not at rest, as far as we know
it is moving around the galaxy at a speed of 250 Km/s and our galaxy is also
moving. Now if light is a universal constant then would this mean that if we
where to travel from one end of our solar system to the other and back at 99%
the speed of light would it would take less time to travel in one direction than
the other? 

To put into perspective it would be like running on a giant rotating roulette
wheel with a maximum speed relative to the stationary ground. You would require
less energy to reach the maximum speed by running in the direction of the
roulette compared to running against it. Does this also apply to the speed of
light, does it take more energy to reach 99% the speed of light in one direction
than the other?
