While we all take for granted the fact that time's arrow forever points towards the future, physicists have always had trouble showing why this is necessarily the case. A mix of chloroform and acetone might seem like an odd place to hunt for clues, but researchers have used just such a combination to create conditions where for some purposes time actually appears to move backwards.
This research won't take us on a journey to see dinosaurs, but it just might tell us why our Universe is stuck on a one way street.
‘Arrow of time’ reversed in quantum experiment
The recent experiment conducted by an international team of physicists focussed on a principal feature we often use to define time — the movement of energy. But when breaking things down into simple rules, we discover there's no clear reason why a cause has to come before its effect. On the smallest levels, we can flip the formula describing the movements and interactions of particles and still get a useful picture. A clue lies in something called entropy. In a system cut off from gaining energy — such as our Universe — things tend to go from ordered to disordered, giving large scale systems a bias in how energy is distributed.
In terms of the laws of thermodynamics, that means you can't put a hot object in a cold room and expect the room to get colder and the object to get hotter.

To boldly go where no robot explorer has gone before. The made-for-television drama Two Friends , by Jane Campion , and the episode, " The Betrayal ", of the hit sitcom Seinfeld , employs the technique. The Seinfeld episode is a take-off of the Harold Pinter play "Betrayal" and has a character named "Pinter.

Sealab episode "Shrabster" is also in reverse order.
For a few seasons, the revived " Doctor Who " had an extensive storyline focusing on a relationship between the Doctor and his companions' daughter River Song from the future based on "opposite timelines" i. In , the British tv mini-series Rellik Killer backwards tells a story about a serial killer in backwards order.
In , the episode " Once Removed ", from the series " Inside No. The story "The Time Eater" from issue 40 of the comic " Vampirella ", scripted by Jack Butterworth and published in , included the concept of human lives running backwards.
Physicists Demonstrate How to Reverse of the Arrow of Time - MIT Technology Review
People were shown to be exhumed, reunited with families, separated from their spouses in order to attend school, and finally returned to the womb. Dialogue was reversed also. Alan Moore 's short story "The Reversible Man" from issue of the comic " AD " told an ordinary man's life backwards, using the same concept as Butterworth but recasting it as a first-person narrative.
Vaughan wrote an issue of the ongoing Midnighter series told in reverse chronology. The issue explored the fact that the character Midnighter has the ability to calculate millions of possible scenarios for any given situation. The issue does not have the scenes in reverse order, but rather the individual pages run backwards. Issue 43 of Bongo's " Simpsons Comics " is told in reverse order: The penultimate page jumps back thirty years and shows Homer Simpson as a child. The anime television series Touka Gettan employed entirely this narrative method. All 26 episodes were aired in chronologically reverse order, with the first episode being the ending of the story while the last episode being the beginning.
The lyrics to " All Along the Watchtower ", written by Bob Dylan , are, he says, "in a rather reverse order"; indeed, the final verse begins with the words "All along the watchtower", and if reversed, the verses would tell the story in the correct order.

The lyrics in "Rewind" by NaS also tell a story in reverse chronology, with some of the dialogue even being in reverse order. There have also been several discussions as to how the picturisation of Neela Vaanam "Manmadan Ambu" sung by Kamal Haasan himself has been slightly inspired from official video of Coldplay's The Scientist.
