Retrocausality: when the reaction comes before action.

    Retrocausality: when the reaction comes before action. 

When the ball moves, before someone kicks it.  Or we can say otherways retrocausality is like backward-moving film. 

Sometimes, the term retrocausality determines that the reaction is before action. In linear time, the reaction comes after the action. But in retrocausality, action and reaction come to an observer in the opposite order. So if a soccer player kicks a ball. The retrospective model of that reaction is that The ball moves before the soccer player kicks it. 

When we think about the retrocausal model we can imagine that the action and reaction are like the pistons and the ball traveling in a tube. The piston is the action and the ball is the reaction. 

When the piston moves and impacts the ball, the causal reaction is that the ball moves after the piston. In the retrocausal model, the ball travels to the tube. Then the ball moves the piston backward. So the retrocausality is like a backward-moving film. In this model, the piston and the ball are information, and the tube is the time. 

The wormhole takes material through space and time. A black hole is the wormhole itself.  We might think. That retrocausality is the case, where a wormhole brings information from the future to the past. The idea of retrocausality is simple. When the energy level in the particle rises high enough, time dilation turns backward. In this case, the escaping velocity from the particle is the same as the speed of light time stops. And the particle's aging ends. 

When escaping velocity turns higher than the speed of light. Time starts to travel backward. If we think that wormhole is like well. The retrocausality is like a pressure wave that travels up from the wormhole. So if we throw the stone hard enough, it may return from the future to the past. But we need a very high energy level so that the stone itself can return from the hole. 

The past is a higher energy level than the future. That thing causes linear time. 

Time began with the Big Bang. The universe's temperature decreases all the time. That means it loses its energy, and the past is at a higher energy level than today and tomorrow. Energy travels from the future to the past. And if we want to send something to the past we must increase the energy level of the sender higher than the receiver. 

And if we think that this tube is the time, the reason why pushing that piston and ball back to the point where everything begins is that the tube is on the hillside. We must raise the energy level in the retrocausal model so high, that it can push the piston to the top of the hill. So we must kick the ball to the tube so hard that the kick gives so much energy that it can push the piston and the ball through that tube. 

There is the possibility of bringing information from the future to the past by using quantum entanglement or superposition and quantum entanglement. In that model, the superpositioned and entangled particle pair. First one particle will turn to a higher energy level than the other. 

Time dilation causes the lower energy particle to travel faster than the high energy particle in time. 

In some models photon that travels around the superstring forms so high-energy impact wave, that can cause an energy impulse that travels back in time. In that model, the photon travels in the universe around the wire called a superstring. The photon forms a small impact wave at the front of it. And if the energy of that impact wave rises high enough, it causes an echo that travels back in time. 

When the distance between those particles in time is high enough, the particle's sides will turn opposite. The particle that the system sends to the future will rise to a higher energy level than the particle in the past. Because energy travels into the lower energy level. That turns the information flow to the past possible. 

The thing is that thermodynamically is impossible to bring information from the future to the past. The reason for that is that the energy level in the universe is lower in the future. And energy or information always travels in the lower energy direction. 

But it's possible to bring information from the future to the past.  Using superposition and entanglement. In that model, the energy level of some particles can rise so high that information starts to travel opposite direction. Using this kind of system could be possible. To transfer information from the future to the requirement for that is that the energy level of the active transmit particle is higher than a recessive particle in that entirety.
