is a physics genius. He discovered the secret of time at the age of 28 and successfully invented a time machine. He is a sure winner in life!

Just when this great god was about to solemnly announce his great discovery to the world, an accident happened!

Of course, it wouldn’t be called a novel if there were no surprises!

A fire suddenly struck, and he had nowhere to escape and was destined to be burned into a house. I have to say that the offended God is really cruel.

Some people will say to quickly turn on the time machine and run away, nonsense, our male protagonist has an IQ of Newton, + Einstein, no need to remind him!

Just 30 seconds before he became a roasted house bird, the male protagonist started the time machine and escaped from the fire scene.

The story ends here. What kind of novel is that? The novelist’s setting is that this time machine can only go back to the past, and when the trip ends, it can only go back to the time and place of departure. In addition, it cannot transfer the past. Things are sent back to the present. The last one is the most magical. Past actions cannot change the present.

When these restrictions are added up, the male protagonist becomes miserable. He originally traveled back to ancient times and wanted to come back for a while, but when he came back, he was greeted not with flowers and applause, but with a merciless fire. What?

The helpless male protagonist had no choice but to start the time machine again and go back to ancient times. Of course, this process would definitely take a few seconds, and the male protagonist was one step closer to becoming a roasted house sparrow.

In order to avoid this tragic fate, the male protagonist who went back to the past tried every means to change his destiny. Unfortunately, due to limited conditions, everything was a futile struggle. In the end, 30 seconds ran out, and the ripples of the Dirac Sea Gathered at the point of death, the so-called great theories and time machines were reduced to ashes in the fire.

This science fiction novel tells a story about traveling back and forth in the ocean of time and trying to change the ending. It is a little similar to "The Beginning", but the ending is far less beautiful than "The Beginning". There is no way, the novelist won't let it!

The so-called time travel is based on the physics theory of Dirac's Sea.

The twentieth century was an era full of geniuses, including Einstein's theory of relativity, Heisenberg quantum mechanics , Schrödinger's cat , and of course Dirac's sea.

Simply put, the Dirac Sea is a sea of ​​negative energy particles composed of the zero-point energy of the quantum vacuum. For us, these negative energy particles are unobservable, but this does not mean that they are illusory. Where there is matter, there is the Dirac Sea.

The Dirac Sea is extremely vast, and the so-called entire observable universe is just a speck of dust floating on its surface.

According to the theory of Dirac's Sea, a particle may have positive energy or negative energy.

According to the principle of minimum energy, particles in the material world should transition to the negative energy level, but why do we exist?

Dirac's explanation is that these negative energy levels have been occupied, that is, they are in a saturated state. According to the exclusion principle, each energy level can only accommodate two particles with opposite spins, so the particles we can observe Cannot jump to negative energy level.

According to this argument, it turns out that we are all garbage floating in the Dirac sea, and we are the goods that cannot be grabbed. In the

novel, there are two basic laws to be followed when traveling through time and space, one is the law of conservation of energy , and the other is the law of causality.

According to the law of conservation of energy, if you appear in the past, you must borrow energy from the Dirac Sea. Because the ripples of the Dirac Sea spread in reverse time, you can only go back to the past.

According to the law of cause and effect, past actions cannot affect the present, so no matter how hard the male protagonist tries, he cannot change his established destiny.

's novel is indeed very imaginative. It cleverly combines the theory of Dirac's Sea with time travel, but the setting is a bit strange. Since nothing can be changed after time travel, what is the meaning of this kind of time travel? Does

want to remind everyone that there is no real time travel?
