I never believed this would be easy... Base is the Earth and an observer is there. The spaceship moves with a speed of 30% from 299.792.458m/s and time inside the ship goes 5% slower than on the earth. What is the speed of the light inside the space ship a) after observer? b) after pilot?

I think I've got rid of one problem. In my example the spaceship moves with a speed of 30% from 299.792.458m/s. Inside the ship, after the pilot's opinion, the light is moving 5% faster, 314.267.888m/s. When the ship goes 99% of light, the pilot's speed indicator shows 2.125.172.389m/s...

Thank you, I got some idea - and perhaps understanding comes later. Same matter but different example: A spaceship is flying with a speed of 30% of the light and if I calculated right, Lorenz factor is 1,05. Does it mean that the time in spaceship goes 5% slower and "twin paradox" is on...

Lorenz-factor has remarkable influence at speeds near to light, but formula itself has no limits. So, time dilation occurs also with slow speeds. From my point of view (an observer), Venus and Mars have different speeds which means different time dilation and this means different speed of...
