your ship's mass does not increase. it would appear to increase to someone who is applying force externally and who you are accelerating away from at relativistic speeds. this is typical for particle accelerators, not spaceships. another falsehood: cosmic speed limit. you can go as fast as you want. assuming g-forces and collisions with atoms not being a problem, you could do few loops around andromeda, cross billions of light years and be back for lunch. the sun may be gone, but to you only a few hours...
