c-latency

Hitchhiker’s Guide Entry

C-latency is the delay in information transmission due to the speed of light (or c). It is the result of the fact that EM signals (including light) propagate at a less-than-infinite speed, meaning that any information received by a sensor is necessarily delayed from the actual event. C-latency is unnoticeable even over thousands of kilometers, but starts to have an impact over larger distances.

C-latency is distinct in terminology but not in principle from other kinds of latencies, such as latencies caused by processing time or wired information transmission.
