What about lightspeed makes it related to time. Why would really dense things distort time?
In: Physics
Well the special thing about light speed is that if you got an object with mass abow 0 and accelerate it you add kinetic energy to it. Einstein said that E = mc^2 + pc which means that energy is rest mass + momentum. So your total mass is your rest energy + kinetic energy. If you got rest mass as you accelerate you get more massive and require more energy to accelerate further. So you look at how much energy you need to accelerate a 1kg (or any) of mass to v speed. This function approaches a v value, you pick larger and larger energy values and the function gets closer and closer to a v value. At infinity it reaches c, the speed of light. So to accelerate anything to c you need an infinite amount of energy.
