1. The Speed of Light c

2. Is not infinite Although, in OUR little worlds, – it might as well be, since we’re soooo SLOW and light is soooo FAST

3. Why don’t we get to go faster than c ? There are reasons based on THEORY And There are PRACTICAL reasons

4. Theory The way the math works is: Let’s say we’re on a rocket moving at.9c We fire a missile that goes at.9c How fast is the missile going, to a stationary observer? NOT 1.8c ! More like.99c Even if the rocket turns on its headlights, that light still only moves at c (not rocket + c)

5. More theory Mass dilation says your mass becomes more & more nearly infinite as you approach c. So you’re going to need some force to accelerate. Now you’re going a little bit faster. Now your mass is even more. Now the same force you used before is going to have less effect. See where the limit here?

6. Practical According to SEEING RELATIVITY, you’re flying into a more & concentrated and intense beam of gamma rays. Good luck with that. As your mass dilates, you need a greater and greater force to accelerate to an even greater speed. How much force, exactly, do you need, to accelerate to c? Good luck with finding that.
