I read this and I'm not sure if this is the right place to post. If it isn't then I appologise. An object in space accelerates to 2/5 th the speed of light and then stops accelerating travelling at a steady pace. If it doid this 3 times it would travel 1.2c. Now, if something cannot go faster than c then obviously the above situation has a flaw. But I'm walking through the senario and I can't see it: OK, I'm on the object in space and I hit the boost button to go to 2/5c and then switch of the boost and travel at a constant rate. I look around and the stars are too far away to see their movement, for all intensive purposes I'm stationary and so I hit the boost again.... Stepping away from the object an independant observer from a distant galaxy with a telescope that would make Patrick Moore wet his pants looks on as this mad idiot on an object accelerates once, twice and then disappears. Where is the flaw?
