The theory of relativity is a theory developed by Albert Einstein that explains how space and time work in our universe. In layman's terms, it states that space and time are not absolute and are affected by things like gravity, velocity, and mass. This means that time passes differently for someone travelling at a different speed or living near a large gravitational body. For example, if you were to travel close to the speed of light, time in your reference frame would pass more slowly than it would for someone stationary on Earth. Additionally, someone living near a large black hole with extreme gravity would experience time slower than those further away. Everything in the universe is connected by space and time, so based on this theory, they should not be considered separate entities.
