Time-like
From Biocrawler, the free encyclopedia.
In the context of special relativity, time-like separated points (or events) in spacetime have a spacetime interval greater than 0 (see sign convention). This means that the events can be causally connected (i.e. one can be a cause or effect of the other) because light from one event can reach the other. Observers in different reference frames must therefore see the events as occurring in the correct order.
