Since i heard really often that light always travels at the same speed. Even if i travel at half the speed of light, and shine a light to the Front, the light would travel at the speed of light not 1.5 times the speed of light.
With this method we could build 3 long tubes (one for each axis, x;y;z) and then measure how long the light take inside the tubes, with this data we could calculate the speed of this facility in relation to the center of the universe. Is this possible, what would be the challenges?

That is exactly what michelson and morley tried to do. The result no matter how many times they tried was that light travels at exactly the speed of light in any direction.
Why?
1) There is no center of of the universe. Or rather the centre of the universe is everywhere.
2) Light travels at the speed of light compared to anything else.
