Chapter four hundred and eighty sixth cause and effect
"Three million-year-old lolita, I always feel like this setting is the same as something." Li Ningfeng is slow to understand, so he always gives people the illusion of strong receptivity.
Qingqiu blushed and quickly wrote in the air, "No."
Qiu Yu patted Qingqiu's head, "Is it the principle of relativity caused by the speed of light travel?"
"Relativity?" Qiu Yan spent two seconds recalling it, and then spent the same time denying it. "The word is correct, but the theory is wrong."
Qian Xiao shouted, "Hey, your denial will not only collapse the scientific foundation of a certain planet, but at least it will cut off countless future development directions."
Qiu Yan looked at him strangely, "Isn't it a good thing to correct mistakes before causing disaster?"
Qiu Yu grabbed Qian Xiao's collar and pulled him away, "He just wants to get something from you in this way."
Qian Xiao said with a bitter face, "Master, if I don't lead you like this, you would be cheating your teammates."
"Is this so..." Qiu Yan sighed softly, "Intermediate civilization is not supported by exchange items. After winning this game, other civilizations need thousands of years to accumulate knowledge.
They will all be given to you by the Destruction Game, so even if I don’t say anything, you can quickly get everything you can imagine.”
Qiu Yu said, "But before that, I still hope to understand everything about Qingqiu."
Qiu Yan nodded, and his ten fingers danced rapidly in the void, as if he were creating an entire universe from scratch. The galaxies rotated one after another, colliding with each other, and the scene of birth and death surrounded everyone.
"The essence of time is the value of space motion generated by the energy exchange between all things and the universe. Because the universe itself is in motion all the time, all existences in the universe produce macroscopic time in passive space motion. And
Because this time is a cosmic-level value, there is almost no possibility of reversal and stoppage. However, in addition to macroscopic time, individual objects will also produce individual microscopic time due to their additional motion in the universe. To a certain extent
,Micro time can eliminate some of the effects of macro time.”
"For example, after a person is born, due to the flow of macroscopic time, he is destined to grow from small to large, then age and die. But if he is frozen, the energy exchange generated by cell movement will be reduced, and the individual's microscopic
Time will slow down accordingly. Taking a step further, if cells or even lower-level microscopic particles are completely stationary, and the energy exchange value with the outside world is zero, then this person's microscopic time will be completely stationary. Of course.
To completely stop the microscopic time of an individual or a range requires investing hundreds of millions of times of energy to counteract the torrent of macroscopic time. Unless necessary, no civilization would have such an inefficient method to stop time."
"What is the most efficient method?" Although he knew Qiu Yan would continue talking, Qian Xiao couldn't help but ask.
"In each universe, the value of space motion for energy exchange is limited to the speed of light, and not all motion can reach or be close to the speed of light. This means that the closer you move to the speed of light, the closer you are to the entire universe.
The static state. If you use higher-level knowledge to explain it, all the objects you see exist because of constant motion, so all distances or sizes in space are caused by the current motion at the corresponding speed.
The energy form of this level. For a simple example, when you are stationary or moving at low speed, the size of the earth is the size you see, but when you approach the speed of light, the low-level energy of the earth itself will change from your
disappear during observation, only energy exchanges at the same level or higher than yours will remain, so the earth at this time will become quite mini. As you get closer and closer to the speed of light, surpassing more levels of energy exchange, the earth will
It becomes smaller and smaller, becoming the size of a basketball, a table tennis ball, or even an atom. When you reach the speed of light, the earth will disappear directly from your observation."
Qian Xiao subconsciously raised his hand and asked in a hoarse voice, "So when approaching and reaching the speed of light, it's not that time slows down, but... the distance becomes shorter and disappears? Then for the moving party, isn't it the same?
Will it disappear because it reaches the speed of light?"
"The disappearance mentioned here only corresponds to the observation phenomenon under macroscopic time. The observer itself still exists." Qiu Yu pressed his temples hard, "The effect of traveling with a starship is that the closer to the speed of light, the original distance in the universe will disappear.
The shorter it is, when it reaches the speed of light, the distance between the universe will completely disappear. For people on board the starship, it is almost as if it has just started one second and has reached its destination hundreds of millions of light years away in the next second.
"
Seeing Qiu Yan's affirmation of Qiu Yu's words, Qian Xiao was moved in his heart and exclaimed, "Doesn't this mean that as long as you have a starship, you can roam the entire universe at will?"
Qiu Yu shook his head, "You use the starship to travel at the speed of light, which only causes the starship to disappear from the macroscopic time flow of the universe that you observe through the microscopic time perspective because it has reached the upper limit of energy exchange. But for normal observers, you still
It exists in the universe that he can see. In other words, if you have to travel a distance of one light-year, then in the eyes of the entire universe, it takes you one year to travel, and you have to travel a distance of 100 million light-years.
, then you really spent a hundred million years."
Qian Xiao twitched all over, "I found out that I have a phobia of starships. If I accidentally set it to fly for hundreds of millions of years, wouldn't it be too late to cancel it and I would be the last human being in the blink of an eye?"
Qiu Yan raised a finger, "This kind of thing will not happen. The environment in the universe is changing all the time. Even a super-civilized computer cannot calculate a safe route of tens of thousands of light years, so if you
If you really set a destination hundreds of millions of light years away, it will definitely be smashed into cosmic dust on the way, or it will be used as a windfall by a civilization that lives by hunting starships."
"Is the speed of light the upper limit of speed?" Qian Xiao struggled.
"It's just the upper limit of natural speed."
"Is there really super-light speed? What would happen if we move at super-light speed?"
"Beyond the speed of light means transcending the movement limitations in the universe. Your own time loses meaning to the universe. The result is that while you ignore the distance, the universe also ignores your movement. It can be understood as unnecessary
The effect of any time-consuming jump or wormhole crossing. But this ignores only the time. Under the energy law, moving at super-light speed requires a lot of energy support. The amount of energy you can use determines the length of your jump.
.But this is already the realm of advanced civilization, and there is no need to search deeply now. In short, after understanding the above content, we can return to the issue of Qingqiu. Fifteen years ago, she was three million light from the earth.
Years ago, it took her four days to return to Earth..."
Qiu Yu asked, "Wait a minute, how did these four days come about? Isn't that starship flying at the speed of light?"
"With this level of civilization, it is only infinitely close and has not reached the speed of light for the time being." Qiu Yan's fingers quickly slid in the air, and a set of symbols flashed past. "With this formula, we can calculate..."
Qiu Yu said slightly reluctantly, "Can I do the math myself?"
Qiu Yan smiled knowingly, "This is the speed distance formula. The reduced dynamic distance is equal to the speed of light minus the current movement speed per second divided by the speed of light multiplied by the static distance."
