Scientists Have Shown There's No 'Butterfly Effect' in the Quantum World

Of all the reasons for wanting to time-travel—saving someone from a fatal mistake, exploring ancient civilizations, gathering evidence about unsolved crimes—recovering lost information isn't the most exciting. But even if a quest to recover the file that didn't auto-save doesn't sound like a Hollywood movie plot, we've all had moments when we've longed to go back in time for exactly that reason.

Theories of time and time-travel have highlighted an apparent stumbling block: time travel requires changing the past, even simply by adding in the time traveller. The problem, according to chaos theory, is that the smallest of changes can cause radical consequences in the future. In this conception of time travel, it wouldn't be advisable to recover your unsaved document since this act would have huge knock-on effects on everything else.
