Hi, I read this from a website, which says, INFINITE ACCELERATION: Acceleration (according to General Relativity) has the effect of dilating time. A photon undergoing infinite acceleration/deceleration would 'experience' no elapsed time on a journey of any spatial length.At infinite acceleration one can travel anywhere in no time, just as one can be transported anywhere while experiencing the infinite acceleration of an Ancient Future dance performance. In classical mechanics, zero mass would result in infinite acceleration. Now light has no mass (meanng it has no inertia), yet it has a constant speed. Therefore, my question is how can light travel at a constant speed and have no infinite acceleration when it does not have any mass or inertia? How can light have no mass and yet behave as if it did have mass?
