As a clock approaches the event horizon of a black hole, time dilation effects due to the intense gravitational field cause time to appear to slow down for the clock from the perspective of a remote observer. At the event horizon, time appears to stop entirely for the clock from the observer's viewpoint. This is a consequence of general relativity, where gravity can bend spacetime and affect the passage of time.
