An [[infinite regression]] is a proposed chain of causation in which each purported cause itself requires another event of exactly the same type to cause ''it.''

This begs the question of what set the original chain in motion--in short, what was the "first cause." Whether all things must have a "first cause" or not, is a subject of debate. Some would suggest that infinite regression is a variant of [[perpetual motion]], something no inventor has ever been able to achieve and which no [[patent]] examiner has ever (thus far) accepted as valid.
