Time dilation is the difference in elapsed time as measured by two clocks, either due to a relative velocity between them, or a difference in gravitational potential between their locations. When unspecified, "time dilation" usually refers to the effect due to velocity. Since the black hole creates a massive curvature in spacetime with its gravitational fields, Miller's planet experiences extreme time dilation. Because of this time dilation from Gargantua's gravitational fields, time on Miller's
