Understanding What Relativity Is
Relativity is a theory developed by Albert Einstein that explains how space, time, and motion behave. It shows that these things are not fixed—they change depending on speed and gravity.
Special Relativity
Special relativity focuses on objects moving at constant high speeds. It reveals that time slows down for fast-moving objects and that nothing can travel faster than light.
General Relativity
General relativity explains gravity as a curve in space-time. Massive objects like stars and planets bend space, causing things to move as if they are being pulled.
Everyday Examples of Relativity
GPS satellites must adjust for relativity to stay accurate. Light bending around the Sun and black holes warping space-time are also results of relativity.
Why Relativity Matters
Relativity helps us understand the universe, from the behavior of planets to the creation of black holes. It also powers technologies that rely on precise timekeeping.
The Simple Takeaway
Relativity explains how space and time change with speed and gravity. It reshaped physics and revealed that the universe works in surprising ways.
