space-like
/ˈspeɪslʌɪk/Physics
adjective
Resembling or having the properties of space; specifically designating an interval between two points in space-time that can in principle be observed to be separated only by space (that is, to occur at the same point in time as seen by a moving observer); relating to such an interval.
- Events separated by space-like intervals are causally unconnected: there is too much space between them for light to pass from one to the other (they lie outside each others' light-cones)..
Origin
Early 20th century; earliest use found in Ludwik Silberstein (b. 1872). From space + -like.
