Temporal resolution

Temporal resolution

Temporal resolution refers to the precision of a measurement with respect to time. Often there is a tradeoff between temporal resolution of a measurement and its spatial precision (spatial resolution).

This trade off can be attributed to the finite speed of light, and the fact that it takes a non zero time interval for the photons carrying information to reach the observer. in this time, the system might have undergone some changes itself. The relation of this with respect to spatial resolution is clear in the fact that the longer that the light has to travel implies a lower temporal resolution as explained above.

This reasoning is subject to contention however, challenged by the same teaser posed in the first few chapters of Stephen Hawking's "A brief History of Time". Gravitational effects seemingly are not subject to this time delay (if one uses the Newtonian concept). However, the (impending?)discovery of gravitational waves could throw more light on this concept.
