Three questions
1:Speed of light is always constant.
Q:What happens when it is affected by gravity? (eg Light is pulled into black hole. What would happen if you fire light upward on surface of black hole?)
2:Galileo's "Principle of relativity" states that all steady motion is
relative and cannot be detected without reference to an outside point.
Q:What happens if you measure your mass? If you are moving with
high uniform velocity wouldn't your mass increase relative to your rest
mass?
3:It is said that it is impossible to achieve speed of light because of mass
dillation.
Q:Mass dilation is the increase in the mass of an object as measured from any other inertial reference frame in relative motion to the first. That means if you are travelling inside a rocket travelling at speed of light and measure the mass of the rocket, the mass of the rocket would be the same as the rest mass. The mass only increase when measured by outside observer. This means rocket's mass does not increase.
Even if the mass of the rocket increases, then so does the hot gases expelled through out the nozzle of the rocket. The rocket accelerates by forcing large volume of gases backward behind it. This means if the rocket provide cosntant thrust, then it would continue to accerelate at same rate.
