Proper time is the pseudo-Riemannian arc length of world lines in four-dimensional spacetime. From the mathematical point of view, coordinate time is assumed to be predefined and an expression for proper time as a function of coordinate time is required.
Proper time is also called clock time, or process time, and it is a measure of the amount of physical process that a system undergoes. For example, proper time for an ordinary mechanical clock is recorded by the number of rotations of the hands of the clock.
Jul 29, 2020 · Would the coordinate time be the time the observer far away from the location of the two events occurring in the gravitational field (i.e. an observer in a flat Minkowski spacetime) measures? In general, how does the distinction between coordinate time and proper time work in general relativity?
- Really, the coordinate time between two events could be that measured by any observer, not necessarily far away. As you said, for the person who ac...
- I honestly believe this sort of questions require some formulas. First of all, let us agree on the setting. In general relativity (GR) the metric $...
- Coordinate time is like coordinate position: it's a coordinate. Coordinates in relativity are like coordinates in ordinary geometry, and you can ca...
Definition: Proper Time. The proper time is an invariant quantity that can be determined from the spacetime interval. Another name I like to use for proper time is wristwatch time*, because it is the time interval measured by an inertial observer who is present at both events.
Overview. proper time. Quick Reference. The time as measured by any observer from a clock at their location that is stationary with respect to them. In the theory of relativity, time is said to be proper to each observer.
If you’ve had special relativity, you recognize this as the square of the proper time difference Δτ between the two spacetime events. (The proper time — often called wristwatch time in EBH — is the physical time in an inertial reference frame in which both events are simultaneous.) Sometimes
Feb 11, 2016 · The proper time noted by convetion τ (tau) is by definition the time measured by an observer in their own rest frame, i.e the time between two events as measured in a frame where the events stay in the same position.
