relativitätseffekt

Relativitätseffekt refers to a set of phenomena predicted by Albert Einstein's theory of relativity that describe how gravity and motion affect the passage of time and the measurement of space. There are two main components: special relativity and general relativity.

The special relativity effect, often called time dilation, states that time passes slower for an observer who is moving relative to another observer. The faster the relative speed, the greater the time dilation. This effect has been experimentally verified, for example, with atomic clocks flown on airplanes.

The general relativity effect, known as gravitational time dilation, posits that time passes slower in stronger gravitational fields. This means a clock closer to a massive object, such as the Earth, will tick slower than a clock further away. This effect is crucial for the accurate functioning of GPS systems, as the satellites experience both special and general relativistic time dilation.

Another consequence of relativity is length contraction, where objects moving at high speeds appear shorter in their direction of motion to a stationary observer. Both time dilation and length contraction are only significant at speeds approaching the speed of light or in very strong gravitational fields. The relativitätseffekt fundamentally changed our understanding of space and time, moving from a fixed, absolute framework to a dynamic, interwoven spacetime.
