Are particles moving in the future equivalent to antiparticles moving in the past? 100 points bounty

Three different time arrows.

The degree of disorder or entropy increasing with time is an example of what is known as a time arrow. The arrow of time distinguishes the past from the future, giving time a direction. There are at least three different time arrows:

The first is the thermodynamic time arrow, i.e., the disorder or entropy increases in this time direction; Then there is the psychological time arrow, which is the direction in which we feel the passage of time, in which we can remember the past and not the future; Finally, there is the cosmological arrow of time, in which the universe expands, not contracts. In this chapter, I will argue that the borderless condition of the universe and the principle of anthropicism together explain why all three arrows point in the same direction. Also, why there must be a well-defined arrow of time.

I will argue that psychological arrows are determined by thermodynamic arrows, and that both arrows must always point in the same direction. If one assumes the borderless condition of the universe, we will see that there must be well-defined thermodynamic and cosmological time arrows. But for the entire history of the universe, they have not always pointed in the same direction.

I will not, however, that only when they point to the same point is there a suitable condition for the development of intellectual life that can ask why disorder increases in the temporal direction of the expansion of the universe.

You can go to a movie and watch the one in the movie where the camera returns, and understand the reverse process of the bullet from the discharge to the target, that is, the process of the bullet flying back into the chamber, you should understand it better.

I think so. It's better to learn physics and be down-to-earth.

Don't think it's awesome to read a book on time and space like a brief history of time.

If you don't have a complete theoretical system, and you don't have enough mathematical skills, maybe you can't even understand the general theory of relativity thoroughly, and you can only understand problems such as wormholes, positive and negative particles, and time arrows, which I can only understand as pretending to x

If you want to understand these questions, you can't stop at the popular science link, otherwise you can only know these things.

On the earth of the positive universe, no matter where the antiparticles move, they can always encounter a positive particle, so the antiparticles in the middle of the positive universe will never escape the fate of being annihilated! Therefore, there can be no satellite-like anticelestial bodies in the positive universe.

I don't think it's actually going back to the past, it's just a shadow of the past, and it's impossible to change history...

The planet that is 3 million light years away from us, if we look at it with a telescope, it will be what it was 3 million years ago, because it takes time for light to travel, and in the same way, if our speed exceeds the speed of light, that is, it is faster than the speed of light to reach a place, then the light we see at that time is the light that came from before, it is the image of the past, in other words, it is not synchronized with the light...

Personal opinion, hehe... It's naïve...

Stillness is relative to motion, and motion is absolute. It means that when a point of change or a turning point is reached relative to the past motion, that point is both static and result, and a new motion is started from this point, that is, the starting point of the new motion, in fact, that point is instantaneous and also in motion, but the past motion is only static relative to the past velocity, and the new motion that has begun is like the starting point.

This is to say that the transient and transient nature of stillness.

This is in which book, motion and rest are physically opposed.

I agree with the upstairs opinion, if you change the computer, or if the same computer deletes all the previous records, it should not be found.

If there is an old version, it should be available in the installation directory after installation!

If it's on the same computer, you can find it in the avatar settings. In the first line is written my avatar.

If you can't find it, you can only find it yourself.

What's the matter, digging this veteran qualified? The tile is not easy to pinch word by word. . .

There have been two episodes of Happy Camp, and there are also Sundays, not to mention the 2010 Happy Boys Competition, which is said to be broadcast in April.

There is also a tour of Wuxi on April 23.

That's pretty much it, kiss me one by one.

You want my answer, huh.

The price of this commodity has been reduced by X yuan.

60-x)*(1+50%)=60*(1+20%)x=12This product has been reduced by 12 yuan.

The answer is that it has been reduced by 12 yuan, and now the price is 48 yuan;

You can solve an equation like this: if you drop x yuan, you used to sell y pieces per day, then there is.

60 y (1+, approximate y, get x=12.)

"Giving Sunday", Fast Man Tour, Yunnan Commercial Performance, "Surprise Surprise" ......n multi-......

Let's go and post it, there are a lot of them.

You can go to the post bar and Weibo to see it.

Accounting can reflect past economic activity as well as future, wrong, logically wrong. Accounting can be said to record the history of the company, and the future has not yet happened, how can it react?

Financial accounting reflects the past, while management accounting predicts the future.
