Butterfly effect: Difference between revisions

The '''Butterfly Effect''' was a theory that a [[butterfly]] could flap its wings in one place and greatly affect events in another place, the phrase often being "a butterfly flaps its wings and causes a tropical hurricane." This was a concern in [[time travel]] that travelling to the past and crushing a butterfly could drastically change the future.

The [[Seventh Doctor]] often cited this effect ([[AUDIO]]: ''[[The Dark Flame (audio story)|The Dark Flame]]''), describing butterflies as a "million multi-coloured pieces of time" and being called himself "the butterfly." ([[AUDIO]]: ''[[The Fearmonger]]'') He also contemplated a butterfly flapping its wings in [[Mettula Orionis]] and having great consequences elsewhere in the universe. ([[PROSE]]: ''[[Transit]]'') The [[Eighth Doctor]] confused the theory, mentioning how a [[bat]] flaps its wing and causes a tropical storm. ([[AUDIO]]: ''[[Invaders from Mars]]'')
