Why does gravity affect time?

Question

Hailey Alexander · Accepted Answer

To the best of my understanding Gravity creates a curve in space time. This causes light to bend and since the velocity of light is a constant time must change because of the bending of space.

# V = D xx T# V = Velocity D = Distance T = Time Light must travel a greater distance when gravity causes a curve in space time; since light's velocity is constant, time must slow down to maintain the same speed of light. The greater the gravitational force, the more the space time curves and, consequently, the greater the increase in the distance light must travel around the curving space; that is, the greater the gravitational slowness of time. This is because the values of Distance and Time are inversely related because they are on the same side of the equation. A day is the same as 1000 years, and 1000 years is the same as a day. It is counterintuitive to the human mind to regard time as a variable and velocity as a constant. It is stated that using light years distance traveled by light to measure time is invalid as gravity affects the time.

undefined Gravity affects time because of the phenomenon known as gravitational time dilation, which occurs due to the curvature of spacetime caused by massive objects. According to Einstein's theory of general relativity, gravity bends and warps spacetime, causing time to pass more slowly in regions of stronger gravitational fields. This means that clocks closer to massive objects, where gravity is stronger, tick more slowly compared to clocks further away. This effect has been confirmed through various experiments and observations, such as the gravitational redshift of light and the time dilation experienced by satellites in orbit around the Earth.
