Imagine if that ship goes with that speed of 99% the speed of light .
Uh, no. Time dilation is not linear. Lorenze factor is one over the square root of one minus the ratio between the square of the speed of the traveler and the square of the speed of light.
At 50% speed of light will go slower by only 15%. At 99% speed of light time will still only go 7 times slower.
With a ship capable of 99% speed of light, almost 75 years will still elapse onboard in the time it takes to cover 500 light years, and passenger born on the day of the launch and living a normal human life span will still barely get from earth to this new planet in time to die of old age, assuming his wonder ship didn't take too much of his life in accelerating at launch and deccelerating on arrival.
