Two things -- 1: So if the speed of light is a constant and never changes, no matter what reference frame you're in - then what happens if a person is moving forward at 90% the speed of light and shines a light in the direction of motion? Perhaps I have it all mixed up, but to that person light appear to be going 186,000 mi/s forward. What then would a stationary observer to the side see? A person in a car going 50mph throws a ball forward at 10 mph - the person in the car sees it as moving 10mph forward, a person outside sees it at 60mph. But if light can't appear to be going faster than c, does that just mean the distance appears to be much shorter or what? I'm pretty shaky on the explanation of Lorentz transformations, and who knows I may have just confused myself to the point I'm not making sense... 2: Is the reason that a stationary observer views time differently than a fast moving observer because the fast moving observer is creating a pseudo gravitational force which bends light? Or am I again muddling different theories together?
