'''Teleparallelism''' (also called '''teleparallel gravity'''), was an attempt by [[Albert Einstein]]<ref>{{cite journal | title=Riemann-Geometrie mit Aufrechterhaltung des Begriffes des Fernparallelismus | first=Albert | last=Einstein | journal=Preussische Akademie der Wissenschaften, Phys.-math. Klasse, Sitzungsberichte | volume=1928 | date=1928 | pages=217–221}}</ref> to base a unified theory of [[electromagnetism]] and [[gravity]] on the mathematical structure of distant parallelism, also referred to as absolute or teleparallelism. In this theory, a [[spacetime]] is characterized by a curvature-free [[Connection (vector bundle)|linear connection]] in conjunction with a [[metric tensor]] field, both defined in terms of a dynamical [[Cartan connection applications|tetrad]] field.
