The Law of Cause and Effect 1, the Law of Cause and Effect MeaningThe law of cause and effect refers to the most important and direct (and can be indirect) relationship between all things.

Pen & Fun & Pavilion www.biquge.info means that any phenomenon or thing must have its cause, that is, "things have a beginning and an end, and things have an end"

"Plant melons and get melons, plant beans and get beans"

meaning.

This is exactly the same as fatalism.

The development of life in this life can be achieved by different efforts (i.e., different causes) and different developments (different results).

As the saying goes, "things are done by people"

, "Man Conquers Heaven"

, is the rhetoric of this view of cause and effect.

Buddhism pays the most attention to cause and effect.

Buddhism III Karma believes that in terms of the explanation of the phenomenon of good people getting bad and evil people getting good in society, it is self-karma.

The law of causality in dialectical materialismThe law of causality in dialectical materialism: the view that any state of the universe is the result of the accumulation of states of the universe before it.

Any motion state is the result of the accumulation of its previous motion state.

It has the widest universality.

2. InfluenceOnce time travel occurs, the law of cause and effect must be disturbed.

For example, if you go back to ancient times and kill a fish, and it happens to be the ancestor of humans on the evolutionary tree, and then a whole group of people disappear in the modern world.

What happens to the effect of time travel on cause and effect?

There are four theories: Theory A-Fate Fact (Circularcausation): You try to go back in time to save someone's life, only to find that the person is still inevitably dead, or even worse, your act of going back to the past is the cause of his death!

This theory is the more plausible of the four.

Theory B-alternateuniverse: Go back in time and save someone's life, only to find that nothing has changed when you go back to the modern day!

"Quantum Theory"

, each possible probability could create another universe with that chance, so there are many "parallel universes"

。

When you go back in time and save that person's life, you just create another parallel universe in which that person is alive, but in your universe he is still dead.

But in Jet Li's movie TheOne, it doesn't seem to define parallel space in this way, in the "I" of other universes

Dead energy by the other "I"

Deuce.

Theory C-Success Success: Go back in time, and kill your great-grandfather.

Did you really succeed in killing him?

If you succeed, you can't be born, and therefore you can't go back and kill him, so he won't die, and therefore you will be born...?

And, if you do succeed, when you go back to your point in time and you exist again, you may find that your great-grandfather has become a different person, will you think that this is your great-grandfather?

Or maybe when you go back to this point in time, you've forgotten that you killed your "great-grandfather"

？

This is a contradictory theory, and the most irrational of them all.

Theory d-observereffect: Go back in time and succeed in changing history, but only the time traveler knows what the difference is before and after the change.

The paradox is, why aren't the travelers themselves affected?

In this case, when he returns to the changed modern age, he may become a stranger.

For example, he went back in time to kill his great-grandfather, and when he returned to the present day, he found that there was no record of his own existence in this world.

There is an obvious irrational part of time travel.

The law of conservation of energy mass, if a person uses a time machine to return to the past time and space, there will be some more mass at this point in time in the past for no reason, and a certain amount of mass will be lost at this point in time, and as a result, the mass and energy of the universe will be more than the mass of a person between the two points in time (not to mention whether there is an extra soul amount or anything like that).

There is a theory that if the world line[2] is densely composed of a large group, or epidermis, it is not yet hypothetical what the exact form is.

For this whole collection is made up of mass.

It may be an infinite number of parallel worlds, or only one is a world that we can observe, and the rest are undetermined possibilities.

That is, our world is part of a large mass body.

For example, if a person A goes from the 10th to the 9th and back to the 10th, he goes back from the bifurcation to the 10th where he has an impact.

If it is a parallel world, it means that A has reached another world from the bifurcation point, and the original world is still the same, except for the absence of A, this mass and energy have reached different places through the world line, and the mass and energy of a general group are still conserved.

For the parallel world, it is to move to a different parallel world, and for the world of possibilities, it is accompanied by the change of perspective of everyone.

3. The Theory of Annihilation In addition, there is also a saying, that is, the theory of extinction: for reality, people will ask: "According to theories A and B, the existence of time and space travel is reasonable, but why have we never met people who come from the future?" ”

If there is enough time for human beings, or if the history of human beings is long enough, then it is very likely that human beings will eventually be able to master the technology of time travel and go back to influence history, but in fact there is no sign of this, why?

There is a reason that human beings have died out before they have developed to the level of civilization that has mastered time and space travel technology; To make matters worse, any civilized species has perished before they have mastered the technology of time travel (I am afraid that any civilized species has an irresistible curiosity about history and wants to go and see for themselves); Perhaps, the mastery of this technology is too long a process, and there is not enough time for any of the continuing civilizations to complete it.

Of course, there are many possibilities for the development of history, and perhaps in the future, human beings have already been in our history, but they have been treated as monsters or aliens.

In the case of the extinction of mankind alone, it is not impossible, and in modern times, threats such as nuclear threats from human beings themselves, as well as threats other than human behavior, such as planets hitting the earth and large volcanic eruptions, may turn mankind's dream of time and space travel into ashes at any time.

It's a frustrating statement, but don't worry too much, I'm sure none of today's scientists working on time travel would agree with this idea, otherwise there would be no point in their future research.

Needless to say, if a time machine cannot be created in physical theory, or that any of the continuing civilizations do not have enough time to complete it, it is certain to be extinctional.

In the case that there is a theory that a time machine can be realized.

How would human history work if a time machine were born one day?

It is impossible that no one uses a time machine, there must be someone who wants to use the time machine to change history, and even if he fails, there will be people who will use the time machine again.

If the change is successful, someone will definitely use the time machine for some reason in the new timeline formed.

If this were the case, the history of the world would be constantly changing on the plane perpendicular to the timeline.

If you want to prevent such a situation, you have to stop people from using it, but there is no absolute way to keep the time machine from being used.

Unless it was created, due to the complete destruction of some element, leaving no element that would cause its existence to be discovered, the time travel carried out did not produce the factors that prevented destruction.

In the absence of indefinite progress, the world will eventually reach a world where a time machine has not been born, and then the change will stop.

For example, a person who understands that someone has used a time machine to cause a lot of misfortune or that the power of a time machine is too powerful to dominate mankind, and expects that the time machine does not appear, there may be more or more such people.

If any of them succeed in getting and changing history, the time machine will disappear.

It is also possible that you have gone back to before the birth of the time machine, and made a small gesture due to the butterfly effect that caused the time machine to disappear.

The birth of the time machine will trigger its own annihilation, so the result will return to the history of mankind where the time machine was not born.

4. The law of cause and effect, also known as the "law of cause and effect"

。

The law of cause and effect has three laws, namely: (1) Effects are caused by causes and effects are born from causes: no cause can produce results, and there must be causes if there are effects.

Only because there is no cause can produce fruit, and if there is sufficient karma, it will inevitably produce fruit.

(2) Things to be reasoned for: Ten thousand laws are born and lived, and there is a universal rationality in things.

For example, there must be death in life, there must be dispersion in gathering, there must be separation in union, and there must be bad in success, all of which are inevitable principles.

(3) Existence by emptiness and existence by emptiness: Anything that arises into existence must arise according to the nature of negating reality.

That is, the so-called emptiness can arise from the beginning, and the dependent arising is inevitably void.
