space-time curvature
Mass bends spacetime
Space-time curvature is the bending or warping of the fabric of space and time caused by mass and energy.
In Einstein's general relativity, massive objects like stars and planets don't simply pull on other objects—they curve the space-time around them, and objects follow that curvature.
A bowling ball on a trampoline creates a dip that nearby marbles roll toward; space-time curvature works similarly in four dimensions.
GPS satellites must account for space-time curvature to maintain accuracy.
