Why Does Time Move Slower Near A Stronger Gravitational Field?

💡 The Answer

• This effect, called gravitational time dilation, is predicted by Einstein's general relativity.
• A clock near a massive object ticks slower compared to a clock far away in weaker gravity.
• GPS satellites must adjust for this because their clocks run faster in orbit than on Earth.
• The stronger the gravity, the more spacetime is curved, slowing time as observed from outside.
