When the college students were complaining, a large group of Americans in the other carriages behind were also complaining. Pen & Fun & Pavilion www.biquge.info

Although they really stopped them when they came in and saw everything in front of them, some of the more frivolous people still couldn't help but complain, what hall is empty, the pipes look too fragile, the design is inhumane, unreasonable, and so on.

Anyway, it's a bone in an egg.

When the trip began, someone translated the trip in 5 minutes, and suddenly a group of complaints exploded.

"The journey takes 5 minutes, I remember when I said that the trip was 312 kilometers in total, doesn't that mean the average speed is 3744 kilometers per hour?

The people in the same carriage all turned their heads to look at a man who had not spoken since he came in, this man was from SpaceX, a technical expert that Ma Yilong relied on, and one of the designers of the super train.

"I remember the super train in the Hyperloopone program, which was designed to reach a speed of only 1,200 kilometers per hour?"

The Hyperloop technologist also nodded with a constipated look on his face.

There is also a subtext to design speeds, which are often subtextual, and that is that it is difficult to achieve.

If the design speed is 1200 kilometers per hour, maybe the real operating speed is only 1000 kilometers per hour, or even 800 kilometers, even this speed, it is close to ordinary civil aviation, and this mode of transportation is not affected by the weather and climate.

So what is the concept of 3744 kilometers per hour?

Mach 3 per second!

So far, there are probably less than 100 humans who can reach Mach 3, and each of them is the best pilot in each country! It is estimated that most of them are old pilots who have flown blackbirds. And that's an airplane!

By the way, the Japanese pilot who was helped by the mecha god soldier some time ago is also counted as one.

"So, something must have gone wrong?" said a NASA expert, "it should be fifty minutes...... ......."

That's the only way it makes sense.

Everyone nodded their heads.

If it really goes at 3744 kilometers per hour, it's too perverted......

"However, if you want to launch an object into space through a magnetic levitation orbit, you need a minimum initial velocity of 7.8 kilometers per second, which is 28,000 kilometers per hour......

I don't know who said it, and it made everyone feel deep malice.

It's hard to dismantle!

Sure enough, is it impossible to build such a theoretical thing as the earth stone thrower?

Because if the earth stone thrower wants to send satellites, spaceships, and space capsules to space, it must reach a speed of 28,000 kilometers per hour...... Compared with this, what is the speed of 3744 kilometers per hour?

But at such a speed, they couldn't believe it.

If you can't even reach a speed of more than 3,000 per hour, how can you reach a speed of 30,000 per hour?

For a while, everyone didn't know what to say, and their hearts were full of unspeakable frustration, and they didn't know whether they hoped that Lazy God Technology could do it, or that they hoped that Lazy God Technology could not do it.

At this moment, in the carriage in front, Lu Zhenguo and Chu Chunhui shouted almost at the same time: "Impossible!"

Shang Fang, who is an engineering man, has already calculated this theoretical speed at this time.

When he said it in a tone full of doubts, even Lu Zhenguo and Chu Chunhui, who had always been calm, were already stunned by this number.

But...... If you run 312 kilometers in 5 minutes, there are 12 5 minutes in an hour, that is 312 times 12, and the speed is not 3744 kilometers per hour.

But the maglev train in the magic capital has a speed of only more than 400 kilometers......

Is this really a train?

"So, sure enough, it's a 50-minute flight, they must have said it wrong. "The college student felt his bladder, well, if you hold it for 50 minutes, it's still fine.

Then they heard the old Professor Shen sitting next to him smile, and sank his back deep into the seat.

At this moment, a soft female voice sounded: "The journey begins." ”

"Bang", everyone who raised their heads and wanted to say something, only felt that a huge force pressed over, pressing them tightly on their backs, and it seemed that they were even a little difficult to breathe for a while.

"This speed ......," the eyes of several NASA engineers widened.

Especially the SpaceX engineer, Ma Yilong has a more famous company besides SpaceX, that is, Tesla.

The acceleration of Tesla's electric sports car to 100 kilometers has even been shortened to 2.8 seconds!

But this engineer is used to driving a Tesla, and at this time, he knows that this acceleration is much faster than Tesla's 100 kilometers per 2.8 seconds!

After the initial discomfort, everyone's eyes swept to the display next to them.

Departure time: 9:10 a.m., estimated arrival time, 9:15 a.m.

Current speed: #%, is a series of numbers that keep scrolling upwards, and you can't see it at all.

Current acceleration: 13.87 m/s.

The acceleration of 13.87 meters is about 1.4 times the gravity, which is still within the range of ordinary people, and it will not cause much discomfort, but this kind of pushing back feeling, even a supercar does not have.

Shang Fang silently converted, and exclaimed: "Accelerate to 100 kilometers in two seconds!"

Even the best production car at present, the Bugatti Veyron accelerates to 100 kilometers in just 2.5 seconds.

"No, it's a real ......."

"It must be a deception......

"But this feeling of pushing back ......"

Everyone present had an indescribable sense of absurdity at this time.

They all looked up at the display in front of them, and the numbers jumping on it, 2 digits, 3 digits, 4 digits...... Then the number in front of me jumped sharply, from 1 to 3, but it took a few tens of seconds.

"It's about to reach 3,744 kilometers per hour!" Lu Zhenguo shouted without any image, he felt that he had never been so out of shape.

But every man has the factor of pursuing speed in his blood, and the rapid surge of speed makes his adrenaline hormones soar, and his scalp is about to explode with excitement.

"Wait, why is it still rising?" Suddenly, Lu Zhenguo shouted.

On the current speed, the display has obviously exceeded 3744, but it is still changing wildly, and it will become 40xx in a short time.

"Didn't you say that the average speed was 3744 per hour?"

"That's right...... If it is a constant acceleration, the average speed is equal to the minimum speed plus the maximum speed divided by two......" Shang Fang smiled bitterly, "Since just now, we have been accelerating at a constant speed, and if we accelerate halfway and decelerate halfway, the maximum speed should be ...... 7488 km ......"

At this moment, a soft female voice sounded: "The shuttle bus has accelerated and is about to enter a deceleration state, and the carriage will automatically rotate 180 degrees, please hold it well." ”

Everyone only felt that the whole carriage was turning, and everyone rotated 180 degrees, and then the soft female voice prompted again: "It's about to start slowing down, please sit down and hold on." ”

The display in front of them, the acceleration position jumped, to -13.87 meters per second, and then the current speed began to decrease rapidly.

Of course, because the back is still facing the pressure, so the crowd doesn't feel too much.

Before everyone had time to react, a soft female voice had already sounded: "The trip is over, please get off within five minutes, the next departure direction, Qingyang Campus, the next departure time, 9:20, thank you for taking this shuttle, I wish you a happy journey." ”

The crowd sat motionless, looking confused.

Arrived?

Where's it going?

Didn't you just sit on it?

What kind of lazy god technology do you play people?

Just get in the car and you let people get off?

Where can you get to such a big time?

Are you going to drag us to the wilderness and kill us?

It can't be, it's absolutely impossible!

Mom, I'm going to call the police!

And in the next car, all kinds of American scolding are even more resounding, what F starts, S starts, B starts......

They peeked out, and it was still the high-tech underground hall outside, just like when they sat in, and they were just playing with them.

"Couldn't it be that we played for five minutes just now......" The college student's face was strange, "Is this coming back again?"

Only Professor Shen leisurely unbuckled his seat belt and stood up, first looked at everyone's faces, and smiled: "The expression is good." Then he waved his hand and said, "I'll go first, the fritters in the canteen of the Dongbin campus are very delicious, and I can't buy them if I go late, and they are still waiting for me to bring them back." ”

As he spoke, he stepped out of the door with his hands behind his back, stepped on the maglev floor and disappeared.

"wa-a!" A dissatisfied call outside the door woke Shang Fang, and the little robot 228 held the luggage in his hand, shaking it impatiently, and snatched your luggage away without saying a word.

Standing in place and staggering for a few minutes, Shang Fang staggered with his luggage, stepped on the maglev floor, and rose to the ground.

This...... What were you doing all morning?

Why did you take a shuttle bus and come back?

How can I go back and tell my mother?

Didn't make it? Forgot to bring something?

Behind him, there was a group of angry old white men, speaking national scolding in various languages, angrily pushing and shoving each other, going out to find someone to theorize.

One by one, they stepped onto the maglev floor and went to the ground again.

When he came out of the ground, Shang Fang's eyes widened suddenly.

It's not a lotus in front of you.

He rubbed his eyes, rubbed them again, and no matter how he rubbed them, he saw the familiar campus in front of him, his nose was full of the smell of the ocean unique to the Higashihama campus, and he seemed to be able to hear the sound of the rushing sea in his ears.

To the left, the endless sea spreads out not far away, and the crashing waves seem to be visible.

Looking to the right, a three-story building reads, "Higashihama Campus 3 Cafeteria." ”

Old Professor Shen was smiling and carrying a bag of fritters out of the 3 canteen, waving his hand and saying, "Look, it's scared......! Goodbye, come to me when you go back, I'll give you a bag of tomatoes, absolutely delicious, I'll get off the train and go back!

Feng Fenghuo especially likes to watch the old Professor Shen who is scared by others with his hands behind his back, stands on the maglev floor, and descends to the ground.

Watching his back disappear, Shang Fang didn't know what to say.

You have been traveling 300 kilometers just to buy a few fritters in the canteen?

And back and forth, 600 kilometers, only 15 minutes!

Could it be that after giving lectures to the engineering monks in his class, he can still organize a group to go to the liberal arts department of Qingyang headquarters to see a beautiful woman and then come back to continue the class?

It's a happy day to think about......

But such a beautiful thing must be a dream!

"Whew!" the college student next to Shang Fang screamed, "Why twist me!"

"It wasn't a dream......" (To be continued.) )
