After dinner on Sunday, Gu Lin and the two met for a weekend routine - watching a movie, and today's theme is "Interstellar". Pen % fun % Pavilion www.biquge.info

"Eh, you did it on purpose yesterday, right?" Yan Yan pushed Gu Dongyang, who was sitting next to her, with her elbow pushing, she was still snorting melon seeds in her mouth, and she was very idle, although it was a little inconsistent with the theme of today's movie.

"Are you talking about my stream stunt?" Gu Dongyang smiled, a little embarrassed.

"What stunt? flow? Her eyes widened like Doraemon, surprised and suspicious.

"Uh-huh—"

"Uh—where did you study?" Lin Yanyan has not been in the rivers and lakes in the past few years, but I don't know that there are such genres, which sounds so chic.

"Uh-Grubby."

"Who? Gabby? ”

"Forget it, you don't know!"

"How do I know if you don't say so?"

"You don't know what I said!"

"You don't say how do you know I don't know?"

"I just don't say it, and I know you don't know!"

"You didn't even say how did you know I didn't?"

"I don't know if I say it, you definitely don't know!"

"Are you going to say it or not?"

"Don't say it!"

"Cut—what's the big deal!" Yan Yan's eyeballs pushed up again, "Don't wait and take the initiative to tell me without discipline." ”

"Well, it's a famous European player of Warcraft." Gu Dongyang still said.

"Oh, I know about World of Warcraft!" Yan Yan thought she knew a thing or two about such a famous game.

"Well, when I didn't say it!" But Gu Dongyang wanted to die very much.

Lin Yanyan didn't understand why Gu Dongyang's expression looked like that ghost, could it be that he was wrong? Aren't they a game? Isn't it Blizzard's "World of Warcraft"? Isn't that game role-playing doing tasks to fight monsters and level up?

"Eh-" Yan Yan remembered something.

"Shhhhh Gu Dongyang made a gesture of silence.

"Haven't you seen it? It's not a premiere again! She muttered.

"There are a few details at the beginning that I didn't pay attention to last time, and I haven't understood them since."

"Is this hard to understand? Isn't it that Murphy's dad went to space and then discovered a new habitable planet to save all mankind? ”

…… I didn't talk back, it seems that I was impressed by Yan Yan's concise summary, although some people say that they read a lot, but obviously not everywhere can be played, some things, or have to rely on understanding people to be simple and rude.

"Well, do you know what dimensions we are?" About half an hour later, Gu Dongyang asked.

"Anyway, I have three measurements, you-this is neat up and down, it should be a circle, right?" She smiled and smiled, and there were words in her words.

…… There were more seconds of silence, and there seemed to be a row of crows flying overhead.

"I'm asking, do you know that we are creatures in several dimensions?" Gu Dongyang's decibel level rose, and he actually learned Yan Yan's eye-rolling stunt.

"Uh—three-dimensional, too?" Only then did she realize that she had gone astray.

"Yes, we are three-dimensional creatures, living in a four-dimensional space." Gu Dongyang finally put her on the right track.

"Uh—what's that five-dimensional?" The problem is always unexpected.

"I don't know much about this, but I've seen it when I see that the fifth dimension is a time body, and this time body is the five-dimensional space, which is composed of countless four-dimensional spaces according to a certain axis." Gu Dongyang's achievements in some aspects are obviously limited to the skin.

"Then why should the four-dimensional space be grouped together according to a certain axis?" Yan Yan really doesn't understand.

"Uh- I actually wanted to say that Murphy's dad fell into the fifth dimension, so he could see everything about Murphy and send his own signals."

"Because in the fifth dimension, you can move along the fourth dimension, change the choice of the fourth dimension, and let it go towards the outcome you want. But you have to wait for this process, and you can't get to the end directly. ”

"Why can Murphy's dad exist in both four-dimensional and five-dimensional space?" Yan Yan felt that it was very unscientific, how could a person appear in two spaces at the same time.

"Uh--in principle in the five-dimensional space is to change everything that happens in the four-dimensional space, and to make the whole world move towards the desired result."

But how can it be possible to change the past? The past is gone! "My head is dizzy.

"The passage of time in the five-dimensional space is not the same as the time we understand it!"

"What's the difference?" Yan Yan's curiosity is very strong today.

"Watch the movie!" Gu Dongyang pulled Miss Lin's head towards the TV screen.

In the movie, Murphy's father came out of the wormhole to watch the image of Murphy's brother and Murphy from the earth, they have gone from teenagers to middle age, Murphy's father is in tears, but Yan Yan is completely confused, she wanted to ask this last time, but there is no one around, and there is no prompt on the movie subtitles just now, how many years later! Is it really a day in heaven and a year on earth? But how is this like one day in heaven and ten years on earth? Murphy's father is not a fairy, is he still the same as before?

"Why is Murphy's father flying in the sky, but Murphy is being urged by the years on the ground?" Yan Yan asked again.

"That's a good question!" Gu Dongyang applauded.

"There is a sentence in the movie that the spacecraft travels at a speed very close to the speed of light, so let's calculate it at 99.9%, the result is more obvious, and the solution is T0=0.01414T, which means that if you live on the earth for a year, only five days have passed on the spacecraft."

"What are T0 and T?"

"T0 refers to the time elapsed on the spaceship, and T is the elapsed time of the world we are standing on."

"What's the difference between them?"

"There's a formula for the time effect, you wait, it's like this." Gu Dongyang was afraid that someone wouldn't understand, so he took a pen and wrote it on paper, T=T0/(√1-(v^2/c^2).

"What are V and C?" Yu Yan pointed to the formula.

"v is the velocity of the observed body, and c is the speed of light in a vacuum."

"That is, the closer V is to C, the smaller the denominator, and we are now standing in this world, and T is constant, so the time that passes on the ship is much slower than ours, and the closer the ship is to the speed of light, the slower their time is relative to ours."

"But our time is obviously changing, isn't it?"

"Uh-you don't care about that, you remember this, the speed of light is eternal, no matter what movement the observer and the light source do, the speed of light will never change."

Yan Yan shook her head, thought about it, and figured it out, but finally didn't figure it out, "Okay - I gave up!" ”

"Hey—it's really the life of moving bricks!" Gu Dongyang also gave up explaining, because with someone's logical thinking, even if he said a few thousand words, he still didn't understand.

"Don't be a cow, maybe your sister will strayed into the five-dimensional space one day, and when the time comes, she will kill you directly when you are born, or - make you mentally retarded!" Yan Yan leaned over to approach someone and made a throat-slitting motion, Gu Dongyang silently returned his gaze to the movie when he heard this.
