'''Darkness''' is the absence of [[light]]. Humans have great difficulty seeing in partial darkness, though several other creatures seem to do much better. It is, of course, entirely impossible to see in pure darkness, although some creatures such as [[bat]]s that have a sonar system can still "see" in such a case.
'''Darkness''' is also used [[metaphor]]ically in the [[Bible]] as separation from [[God]] and a place without hope.
