Gerard's words caused Lird to fall into a confused confusion, and he stared at Gerard with wide eyes and said, "The door and the key, what are they?"

Gerard said, "I'm talking about a metaphor of intention, so let me tell you, what I'm talking about is space and power. ”

"It looks a lot like sci-fi serialized in a street newspaper," Lird said. ”

Gerald said, "Hey, man, what I'm saying is completely different from what the liars have written, what I'm talking about... Something that could theoretically exist. ”

Lird laughed when he heard this: "According to you, those may not even be as good as the liar's articles, at least the liar's words will make me amused." ”

"Please, don't do that. Gerald grumbled as he put the food in his hand back on the table, looking serious.

Seeing this, Leard said, "You know what? You look like a boxer who is about to walk into the ring, do you need me to give you a braces?"

Gerald shrugged his shoulders and said, "My mouth is a weapon now." Then Gerald picked up a nautical map on his desk and said: "At this time, the nautical map you are familiar with, it reduces the entire sea area according to a fixed scale, and summarizes it on a piece of paper, but this map does not represent the sea area, at least it cannot show the wind and waves and currents in real time. Lird shrugged his shoulders to show some understanding, and Gerald continued: "A map is made up of a sheet of paper, and on the surface it is composed of two dimensions, the X axis and the Y axis, which is often referred to as the length and width of the paper. But this is not the case in the real world we live in, as you can perceive, our world is far more three-dimensional than the paper world, and it also has another spatial axis, which is Z. With that, Gerald picked up a pen on the table and placed it vertically on top of the paper, while looking at Lird to see if he understood what he was saying.

Lird nodded, then motioned with his gaze for Gerald to continue.

Gerald said: "As you know, we can express things in three dimensions in two dimensions, but we can't express all the content in two dimensions, which transcends the spatial limitations of dimensions. ”

Lird paused and said, "You mean that the so-called high-dimensional space eater can't be fully expressed in the low-latitude space?" Gerald nodded and said, "Smart." ”

Lird paused again, "In this world... Or is there a four-dimensional space in this universe?"

Gerald said: "The cosmic space we live in is a three-dimensional world, and there is no four-dimensional space in this universe, but if there is a four-dimensional space in this infinitely wide spatial form, the answer is that there may be. ”

Lird said a little deflated: "After saying so many things, you finally gave me an answer that may exist, and it is really boring." ”

Gerald disagreed: "Although what I said is only hypothesis, but the great ideas made by countless people over the past hundred years also prove the great existence of this era. You know, if I had come up with this theory centuries earlier, I would have been burned at the stake than the number one before. ”

Lird had lost interest in what Gerard had to say, but he thought that there was no good way to pass the time in the middle of the day, so he continued to listen, and listened to the curiosity of what was being said on the radio.

But Gerald, for his part, didn't think so, and instead became more and more interested.

"Although the four-dimensional space is only an idea, it is very likely to exist, it is a higher space that completely overrides the three-dimensional space, and it naturally has one more axis, you can guess what is the excess?"

Liard said: "ZZ axis?"

Gerald cut and said, "It's time." ”

The word "time?" was inexplicable to Liard.

Gerard said: "Different from the length, width and height of three-dimensional space, the extra axis of four-dimensional space should be a time line, which cannot be represented in three-dimensional space, but you can understand it as a time line that starts with a beginning and an end. ”

Lird frowned and said, "Time is straight, which means I can see the before and after performance of a time?"

Gerald nodded: "In three-dimensional space, we can only feel the passage of time, but we cannot observe time with the naked eye, while in four-dimensional space, time can be presented as an embodied form, usually visible and touchable. ”

Lird thought quietly for a moment and said, "Your statement is really becoming more and more metaphysical. ”

Gerald laughed and said, "A lot of physics conjectures will be seen as metaphysics until they are confirmed. ”

Lird said, "If I could enter the space you are talking about and be completely immersed in it, what would happen to me?"

"I can't say exactly what will change, but one thing is certain, when you have a sense of time, you are free to observe and even manipulate it," Lird said. For example, when you are fully integrated into the four-dimensional space, you will instantly grasp my entire life, including my past and future, when you see me again. ”

Lirde said: "Sense the past and the future? Can I see you wetting the bed when you were a child?"

Gerald shrugged his shoulders and said, "You can see how I wet the bed in my old age. ”

Learde laughed and said, "I really don't want to see that scene. ”

After laughing, Lird became interested in Gerald's words again, and thought for a moment, "If, as you say, a person in a four-dimensional space can easily meet the past and future of time, then wouldn't he be..."

"It's God!" said Gerald indifferently.

Learde laughed and said, "Even now you must be an enemy of religion. ”

Gerald shook his head and said, "Religion is faith, and what I am talking about is most likely the truth of the universe. ”

"Well, whether you say it's true or not, whether it's faith or truth, what does it have to do with those so-called 'doors' and 'keys'?"

Gerard scratched his head and laughed, "If you don't mention it, you'll almost forget it." After that, Gerard rubbed his fat chin and said: "As I just said, the four-dimensional space has a visible timeline, and this timeline does not just appear as a straight line, then it is also said that there are nearly countless timelines in the four-dimensional space, and none of the timelines represent a three-dimensional space universe. ”

Lird was stunned for a moment when he heard this, and then looked at Gerald with an incredulous gaze and said, "It's unbelievable, listening to your compatibility, a world like ours seems to be a... Ant nest?"

Gerard said: "In the eyes of the creatures of the four-dimensional space, our threat is far less than that of ants. ”

Lird said: "In this way, the creatures of the four-dimensional space are extremely kind-hearted people, otherwise our world will be wiped out with the flick of a finger." ”

Gerald grinned and said, "On the surface, this is true, but as I mentioned, there are strong limitations in the space of different dimensions. For example, you can easily tear a piece of paper apart, but you can't get into a painting to erase the image on it, and both the paper and the painting are objects in the three-dimensional world, and three-dimensional creatures can't enter the two-dimensional world even though they can exert devastating power on the two-dimensional world. ”

Lird nodded as if he didn't understand, "I see..."

Gerard said: "I have talked so much about dimensional space, in fact, I just want to show that there will be countless time and space axes in the multidimensional world, and these axes are the space of the universe in which we live, and the many three-dimensional axes in this four-dimensional space are parallel universes equivalent to us in our eyes. ”

Lird let out a long sigh and said, "Although all these things you say are unfounded, but after your explanation, I am really a little convinced, and I have to admit that you physicists are much more terrible than newspaper salesmen." ”

"You don't have to laugh at me," said Gerald, "for if one day this conjecture turns out to be true, then I am a great pioneer of science, and you are an ignorant and pedantic man." ”

"I don't care, I would love to see you succeed in my lifetime," Lird said. ”

This time, Gerald smiled bitterly: "What I just told you is just a conjecture of people for many years, and the science and technology needed to prove this conjecture need to be quite powerful, and in my opinion, it may not be possible for human beings to enter that kind of field in a century or two, at least a millennium." ”

Lird said: "It's not so exaggerated, it's not certain what the world will be like at that time." ”

Gerald shrugged his shoulders and said, "Even if the human race is destroyed, there is no way, that can only mean that the human race in the dark cannot break through the barrier of that dimensional space." ”

Lird smiled, "It is also possible that the creatures of the four-dimensional space have already known everything by observing the timeline. ”

Gerard said, "Then that moment is the moment of the destruction of the human world. ”

Lird laughed, "Let's talk about why it's so illusory and extreme. ”

Gerald also laughed: "This is the habitual pessimism of a scientific researcher." ”

After a pause, Gerald said, "You know what? Hitler is said to have been fascinated by this illusory existence. ”

Lierd said: "Yes, I only know that he is an art student. ”

Gerald laughed, "The lost 'artist' is really terrifying, and it can turn the whole world upside down. ”

Lird interjected: "What do you mean that Hitler was fascinated by the unreal?"

Gerard said: "I also have some hearsay news, the German army has begun to lose in the European theater in recent times, and the vast front is also very depleting to Germany, so the German front will inevitably begin to rout, so the best way to achieve victory is to fight quickly." As I told you last time, Germany began experimenting with super-powered weapons a few years ago, but so far it has not achieved much success. So Hitler now put part of his hope on 'mysticism', he wanted to find some kind of ... strength, thus helping him to achieve victory. ”

Lird sneered: "If he is given the ability to control the timeline, then the end of the world is not far away." ”

Gerald said, "Who knows, but it is said that Himmler, a close confidant of Hitler, has assembled a mysterious force to conduct investigations all over the world, with the goal of finding a mysterious force that can be used in war." ”

Liard said: "Sometimes I really don't understand whether you are doing physics research or working in the CIA, where did you get so much information?"

Gerald shrugged his shoulders and said, "Hearsay, you must know that there are all kinds of anecdotes around me every day, and what I tell you is what I think is more reliable, and I heard two days ago that this war was printed by Ares, the god of war." ”

Lird smiled bitterly, "It's ridiculous. ”

After the conversation, the two turned the conversation to some light questions, and the nervous fear of war had been dispelled a lot.

"It's almost Christmas, and there will be a holiday on those days, do you have any plans for it? or where to go?"

Lird smiled: "I have a very peaceful life at this time of year, I just stay in my room and read a book every day, and my grandmother is not in good health recently, so I have to take care of her." ”

Gerald shrugged his shoulders and said, "It sounds like you're as miserable as I am, and every Christmas, I re-read the physics magazine at home for the whole year, and summarize some knowledge points that I am interested in to pass the boring time." ”

Lird said: "Sounds pretty good, it makes a lot of sense." ”

Gerard exclaimed, "Please, what's the point! In my eyes, this is the most miserable way to Christmas, we are not children anymore." Don't hang a sock on your bedside and wait for your parents to pretend to be Santa Claus to deliver you a present. ”

Lird blinked, "Yes, but two days ago Jeanne asked me to prepare a Christmas present for her." ”

"Oh my God!" Gerald exclaimed.

"My man, I'm afraid Gabriel is not as innocent as you. Gerald said helplessly.

"Heh... Is there anything wrong with that?" Lird wondered.

Gerald looked at Lird and said, "What's the problem... That's a really good question, so I ask you, are you going to spend this Christmas alone?"

Lird shook his head and said, "I'm not alone, I still have..."

"Not Mr. Wyatt's family!" Gerard interrupted Lird.

"I mean, you're not going to find a girl to spend Christmas with?"

"Girl..."At this time, even if Lird was slow to react, he understood the meaning of Gerald's words.

Gerald continued, "I'll be blunt, do you like Jenny?"
