   If the velocity of light is gauged by an observer whose speed and direction are indeterminable relative to the motion of all things in the universe, which is moving, the light or the observer? Nothing can travel faster than light, yes? Think about everything the other way around. Nothing can travel slower than a thing that does not move.
   This may require a great leap of imagination but consider this, two trains are moving in the same direction at different speeds on parallel tracks. As one overtakes the other both switch on their lights. A mile down the tracks the beams of light strike an overpass simultaneously. What might be happening other than Einstein's explanation involving variable time?
   Please bear with my rebellious conjecture as I continue. The true motion of the trains is in the opposite direction and they are 'trailing' light behind them like a boat leaves a wake in water. An instant later the overpass which is also moving 'collides' with the light. If these 'light wakes' are being produced at equal rates the objects from which they originate must be moving at the same speed. For this to be possible another dimension of space is required. The slower train is in fact moving at the same speed as the apparently faster one but a component of its velocity lies at an angle outside our familiar three dimensional reality.
   The true nature of the universe will be discovered through Non-Euclidean geometry. Variable time is unnecessary. My humble apologies to Albert.

I have a doubt. If the light source is inside the vehicle, then what will a person standing outside see?( Supposedly everything outside is completely dark)

so if you move at 99% of c, and turn on a laser in the same direction, the light will travel at c? If nothing can move faster than c, hows that possible? Its the same with Earth. It moves over 600km/s in space, but still we have a speed close to light in the LHC. Hows that possible? Special relativity makses sense in soem cases, but not all the time. Not in my head.
