What is time dilation?
i dont really understand how the accleration due to gravity could be constant, because according to the equation g=GM/r^2 where g is the acceleration due to gravity a specified distance from a mass the r^2 suggests that the acceleration is going to raise exponentially as an object gets closer to... -

What is time dilation?
I would just like to ask a question to do with gravity and light speed. The acceleration due to gravity on an object is always x m/s^2 - right, there is no mass involved in this. So if you were to fire a particle or anything at a superhuge mass that has a huge gravitational field around it... -
