Can anyone explain proper time with a simple example analogous to real life please? I am having a problem understanding it.
Thank you
Thank you
Be glad to. It's very, very simple. It's the time on any clock.quellcrist said:Can anyone explain proper time with a simple example analogous to real life please? I am having a problem understanding it.

Chronos said:Simply put, proper time is the time measured by an observer's clock. In general relativity proper time has no absolute meaning because it passes at different rates for different observers due differences in gravity and motion of the observers' clocks. The differences are usually vanishingly small, except in special cases - such as the presence of exceptionally powerful gravitational fields or involving extreme velocities [relativistic speeds].
proper time is invariant, so it does have absolute meaning. Coordinate time is the frame variant thing with no absolute meaning.Chronos said:In general relativity proper time has no absolute meaning because it passes at different rates for different observers due differences in gravity and motion of the observers' clocks.
The concept of proper time refers to the time measured by a clock that is at rest relative to the observer. It is the time experienced by an object or observer in its own frame of reference, and it takes into account the effects of time dilation.
In the theory of relativity, space and time are considered to be connected and cannot be separated. Proper time is a component of space-time and is used to measure the duration of events in a specific frame of reference.
There is often confusion over the meaning of proper time because it is a relativistic concept and can be difficult to understand. It also depends on the observer's frame of reference and the relative motion between the observer and the object being measured.
Coordinate time is based on the time measured by a clock that is stationary in a specific frame of reference, such as Earth's surface. Proper time takes into account the effects of time dilation and is measured by a clock that is moving relative to the observer.
Gravity can affect proper time by causing time dilation. According to the theory of general relativity, the stronger the gravitational field, the slower time will pass. This means that an observer in a strong gravitational field will experience proper time at a slower rate compared to an observer in a weaker gravitational field.
