Spatial relativity

Spatial relativity, often associated with Albert Einstein's theories, refers to how space and time are interconnected and relative to the observer's speed and position. In essence, what one person experiences in terms of time and distance can differ for another moving at a different speed or in a different gravitational field. This means that time can appear to move slower or quicker, and lengths can seem longer or shorter depending on how fast you're moving or the gravitational influences in your vicinity. It's a fundamental concept that helps explain phenomena in physics and the behavior of objects in the universe.
