Time Dilation Near Black Holes: How Time Slows Down as an Object Approaches the Event Horizon

Introduction

Time dilation is a fascinating phenomenon predicted by the theory of relativity, particularly significant when studying black holes. As an object approaches the event horizon of a black hole, time appears to slow down relative to an outside observer.
