How Time Can Run BACKWARDS: New Parallel World ‘Multiverse’ Theory Revealed

In an alternate universe, the arrows of time could run in the opposite direction of what we know, unfolding so that our known past exists during the far-off future of a distant world.

A pair of scientists from the California Institute of Technology and the Massachusetts Institute of Technology who suggest this concept aren't the first to do so, but they've demonstrated how this phenomenon could arise based on simpler principles than previously examined.

Using entropy as the basis for their model, the physicists have developed a way to show the spontaneous appearance of the arrows of time, and how they can flow in opposite directions.

In an interview with New Scientist, Sean Carroll of CIT, Pasadena and Alan Guth of MIT explain that, in the laws of physics, the direction in which time flows does not matter.

By this explanation, time which runs backwards would still go in accordance with the laws.

While humans have grown accustomed to the idea that events lead to other events in a particular order, Carroll says this is not the case.

‘There's no such thing, at a very deep level, that causes [must] precede effects,' Carroll told New Scientist.

In time as we know it, entropy – a measure of disorder – increases.

On a universal scale, this means that ‘the future is the direction of time in which entropy increases,' New Scientist writes.

At a much earlier point in the life of the universe, like at the time of the big bang, entropy would be much lower, the researchers explain.

In their model, which is not yet published, the researchers drop a fixed amount of particles into an infinite universe.

The individual particles each have a randomly assigned velocity, and eventually, arrows of time spontaneously come about, according to New Scientist.

Under these conditions, half of the particles will spread outward toward the edges of the cloud, increasing entropy.

The other half will move toward the centre, decreasing entropy.

Once these particles pass through the centre, they will continue on, heading outward toward the edge.

They're referring to this idea as the ‘two-headed arrow of time.' If an arrow of time emerges in one direction, the same will happen in the opposite.

Regardless of the starting position, the researchers explained to New Scientist, the particles will all eventually move in the outward direction.

The model shows that entropy can grow without limit, indicating that ‘time zero,' would be the point of lowest entropy.

    what if time is slips when we go back to the past and future .

  3.' Davan Deep Starwalker says:

    Multiverse yes, different laws of time, no. What’s different in them r peoples life events and choices they make. Typical “scientists” making physics more important than people, an idiotic bias with no basis in reality.

  4.' Max Davies says:

    For every action there is an equal & opposite reaction.

  5.' Ramanujam Raghavachari says:

    The sequence based on events
    revolves around and picks another sequence which is having a link. This time travel may start from Ramayana period and jumps to the present and pushed back to – Mahabharata period which creates the conflicts in relationship in a new trend. This cycle must find an end.

      Hey Ramanujam Raghavachari bro where from u fetching the Hindu sequence in science field???

    •' Ramanujam Raghavachari says:

      In science the unsolved problem remains in the mind as a – puzzle – and start giving you the headache and getting developed into a mental distress. The life is also like that

    •' Ramanujam Raghavachari says:

      If you feel you are helpless chose to be quiet. otherwise the mental disturbances will attract more physical ailments

  6.' Lee Marion says:

    I definitely need to clock into a reverse time zone—-lol

  7.' Sukha Bhucho Sukhdev says:

    Did not got ….in the Big Bang theory has much remains to be proven yet, the arrows coming in opposite direction ..if u r science related guys not dont mean that everyone would accept whatever u did ..u say ..u claim ..

  8.' Roger Medina Jr. says:

    They say time is an illusion, it is not linear or absolute from what I have heard. I do believe there is more than one reality positive and negative realities that are in conjunction to our reality. Very mind blowin stuff.

  9.' Λίτσα Γώγου says:

    I knew it!!!!!! Chaos is the basic rule in universe…nothing is under control…not even time…but everything works in harmonius laws…Beauty

    Were n the matrix

  12.' Tom Hicks says:

    reminds me of the cool movie “Mr. Nobody”

  13.' Lori Scott says:

    That would be too cool to think Dinosaurs and cavemen could be running around in our parallel. and devolution…

  14.' Ma Mo says:

    I think that God created one universe.

  15.' Thomas Chenhall says:

    Yea this is the new only possible way to account for a multiverse, the empty higher dimensional space that is flowing backwards through the present and simultaneously cohering matter in motion in a state of change, because time flows through it.

    Time as a higher dimensional fluid may flow through the aperture of the atomic nuclei.

  16.' Mollie Holtman says:

    Time is an artificial mental construct created by humans to explain why things change. Because it doesn’t really exist, it can’t go backwards. That’s my story, and I’m sticking to it, lol!
