Under this assumption, the only things that can influence an objectвЂ™s state lie in its вЂњbackwards light coneвЂќ вЂ“ the area of space-time from which light has had time to travel towards it. It represents the maximum speed that any influence can travel in the universe. The key is the speed of light, which relativity insists is a constant. Time is warped by the presence of large masses or when travelling at high speed, and passes at different rates for different observers.Д®ven so, relativity bends over backwards to maintain a sensible conception of cause and effect as we know it. EinsteinвЂ™s special and general theories of relativity, for example, abandon the idea of a single line of time along which causes and effects can be strung. Modern science presents a number of challenges to this naive view of causality. The laws of thermodynamics, which govern the way atoms move, then provide certain rules about what causes can precipitate what effects, and so an overall direction for causality вЂ“ a flow of time. A piston, for example, starts to move when a lot of individual hot atoms hit against it and push it a certain way.

Third, big effects grow up from little causes. You swing your leg, make contact with the ball, and off it moves, in that order and no other. Second, effects follow causes in a predictable, linear manner. If a ball moves, the likelihood is someone kicked it if an apple falls from a tree, itвЂ™s because its weight became too great for the branch it was hanging from.

They donвЂ™t just happen of their own accord. The first big rule of classical causality is that things have causes. In the classical world we live in, it comes with a few basic assumptions.

Causality is the study of how things influence one other, how causes lead to effects. ThatвЂ™s a basic statement of any dynamic world where things change, and things would be very dull if it werenвЂ™t the case вЂ“ not that weвЂ™d exist to know about it, without a cause. But if the laws of quantum mechanics are applied to the causal relations, then one could imagine situations in which the causal order of events is not always fixed, but is subject to quantum uncertainty.Things influence other things. Traditionally, quantum theory assumes the existence of a fixed background causal structure. The emerging subject of indefinite causality in a quantum world may provide new insights into the theoretical foundations of quantum physics and general relativity. Recent research reveals that causal relationships can be placed in quantum superposition states in which A influences B and B influences A.

Without cause and effect, science would be impossible.

They have shown that even allowing causality to be nonlocal вЂ“ so that an event in one place can have an influence on another, distant place вЂ“ is not enough to explain how quantum objects behave.

Otherwise it could cause them Memory Overload due from living different lifeвЂ™s in alternate timelines.

When wormholes are closed on each side of the forth dimension, all the changes ever made to timelines become reversed but the users will still be aware of the experience theyвЂ™ve been through.

If users overuse this power to cause one to many changes to the past and future, it can result into a Timestorm Creation as the fabric of time loses control of everything in existence.

May be limited in terms of how many events the user can change with this power.

By linking individual time periods and causing actions in the past to directly alter the future, this power may also cause any changes in the future to have similar effects to events set in the past such as temporal paradoxes where things in the environments start to freeze around residents present in them. The user has the ability to change the events in the past which, immediately affects the events in the future and vice versa based on each decision made in the present via causality of the fourth dimension.
