GENERAL KNOWLEDGE

Detailed explanation-1: -Albert Einstein’s theory of general relativity predicts that where gravity is stronger, time passes more slowly. That’s called time dilation. Gravity is stronger closer to the center of the Earth. So, according to Einstein, time should pass more slowly closer to the ground.

Detailed explanation-2: -Gravitational time dilation occurs because objects with a lot of mass create a strong gravitational field. The gravitational field is really a curving of space and time. The stronger the gravity, the more spacetime curves, and the slower time itself proceeds.

Detailed explanation-3: -This form of time dilation is also real, and it’s because in Einstein’s theory of general relativity, gravity can bend spacetime, and therefore time itself. The closer the clock is to the source of gravitation, the slower time passes; the farther away the clock is from gravity, the faster time will pass.

Detailed explanation-4: -A gravitational wave passing through the Solar System creates a time-varying strain in space that periodically changes the distances between all bodies in the Solar System (this strain changes distances perpendicularly to the direction in which the wave moves).

Detailed explanation-5: -Another of these persistent gravitational wave observables involves a similar effect to time dilation, whereby a strong gravitational field slows time.
