Time Does Not Exist. Let me explain with a graph.
This video explores the concept of time as a fourth dimension, similar to height, width, and depth. It explains how objects in 3D space can move left, right, up, and down, and then introduces the idea of time as another direction we constantly move through. Using a model where 3D reality is flattened into a 2D plane and time is the 'up' direction, the video explains why moving faster in space means moving slower through time. This model also helps visualize why objects appear to flatten when traveling at very high speeds, aligning with Einstein's theory of relativity. The video suggests that we are like 'flat pancakes' in the fourth dimension, which is why we cannot see through time.
