In fact, space flight will not cause the star-filled sky to flow backwards like in the movie. In fact, the scale of the universe is so large that no matter how fast the airplane is, even the speed of light is insignificant compared to the scale of the universe.
Of course, Long Xinsheng also had a rough understanding of it, so he reacted quickly. But now, the plane is flying straight towards the moon. When the porthole is opened, there is only the bright starry sky and nothing else can be seen.
The plane accelerates slowly, because there is no air resistance in space. In theory, as long as the engine is kept running, the acceleration will increase infinitely. Of course, after it reaches a certain level, it will encounter another kind of resistance, a theoretical resistance - it only exists theoretically now and has not been confirmed, that is, the resistance of space itself. The basis of the theory is the theory of relativity.
But for current passengers, they are all experiencing rare acceleration. For a short period of time, healthy people can withstand three to five times the acceleration of Earth's gravity; but only for a short period of time. Just like strenuous exercise, everyone can run a certain distance. Running three to five hundred meters is no problem; but if you want to run thousands of meters, you can only be a professional.
And that's it, acceleration in a short period of time can be regarded as enjoyment, such as bungee jumping; but long-term acceleration will cause a great burden on the body, especially the cerebrovascular system. Therefore, the master company has specially set up an alarm device. As long as anyone feels unwell, the acceleration will gradually decrease within a reasonable range until the gravity is doubled. In an environment with double gravity, the human body can maintain its best condition.
Long Xinsheng felt the gradually increasing pressure on his body, which exceeded three times the force of gravity. There was no such pressure when the plane took off from the ground. In a gravity environment, it doesn't feel like you are carrying a heavy load, it feels like every corner of your body is filled with mercury.
Five times the acceleration due to gravity!
Looking at the prompts on the screen, Long Xinsheng felt the pressure. Although he usually pays more attention to exercise, and after signing up, the master company also conducted simple training for the pilots, but after all, the body is still weak. In life, even if Long Xinsheng pays attention to maintenance, his body is still in a sub-healthy state.
It's just that - it seems a bit embarrassing to press the button, and such extreme speed is really a wonderful enjoyment.
Fortunately, before Long Xinsheng could decide, someone had already pressed the button. Long Xinsheng turned around and saw that it was Qin Shifang, the person in charge of the Second Construction Group of Qingzhou Province who was relatively close to the master company. After all, he was getting older. He was about to die under 5 times gravity. His face was pale now. It's obviously reached its limit.
Then, Long Xinsheng felt the plane vibrate slightly, and then the acceleration began to slowly decrease. In this case, once the acceleration is drastically reduced, it can directly cause the collapse of the cardiovascular system; without professional training, it is directly murder. Fortunately, the expert company is also experienced, and the acceleration is decreasing at a rate of 0.1 per minute, which is just enough for the body to adjust.
The acceleration gradually decreases until it reaches 0.8 times gravity. At this time, Qin Shifang had fully recovered and looked at the status of the screen next to him with some fear.
With 0.8 times gravity, the aircraft's speed has reached 22 kilometers per second.
In just this moment, the speed of the plane doubled! Sure enough, space is not the Earth’s atmosphere. Not only Qin Shifang, but also fifteen other people were watching. After all, it's really boring to look at the almost unchanged starry sky outside now.
About five minutes later, the plane started to accelerate again, but this time it only accelerated to 2 times gravity without lifting. Everyone was a little stressed, but it was not that uncomfortable. Of course, your body still can’t stand it for a long time, but there is no problem with monofilament for three to five hours.
The driver's powerful voice sounded: "Everyone, we are very lucky. We are very close to Mars now. You can observe Mars with a telescope. What a lucky journey."
"Mars!" Everyone was stunned, and then started observing with the exquisite astronomical telescopes that they had prepared. For this space trip, everyone spent tens of thousands of yuan to buy an extremely sophisticated portable space telescope. After all, 1.5 billion yuan has been spent, so we don’t care about tens of thousands of yuan.
As a person who pursues dreams, Long Xinsheng spent millions of dollars to buy a dual-purpose optical and laser astronomical telescope. The advancement of science and technology has made such a sophisticated telescope look like a portable binoculars, but its functions are... But extremely powerful.
From space, Mars does appear red at first glance. However, if you look closely, you will find that the thin atmosphere is actually blue, just like the Earth. But this is also easy to explain. The ground appears red because it is rich in iron elements; and the dust in the air scatters light, just like the earth, making the sky appear blue.
Long Xinsheng was fascinated by the rugged surface of Mars. Expert companies report that the journey to the moon takes 3-5 hours. The specific situation depends on your body's endurance. So now some people are starting to go to bed.
But... there is always a dissonant voice: I have to go to the bathroom!
The journey has now been four hours. Even on the ground, it has been dealt with in advance, and now most people have reached their limit.
"Please wait."
The plane began to slow down, and gradually, all acceleration due to gravity disappeared. Of course, the current speed of aircraft has reached a speed of 30 kilometers per second, which is almost 110,000 kilometers per hour. Even if the engine has stopped, the plane is still moving forward at high speed.
All the acceleration of gravity disappeared, and at that moment, Long Xinsheng felt as light as a feather again.
"The restroom is at the end of the cabin. Please hold on to the handrails along the way. The plane is currently traveling at 30 kilometers per second. Please pay attention to safety."
In space, people and aircraft are now in a relatively static state. Long Xinsheng also feels a little uncomfortable. He opens his seat belt, grabs the armrest, and flies forward flutteringly. It is a wonderful experience. With a slight exertion of your fingers, you can push yourself far away.
The aircraft of the Master Company use air circulation, and the excrement is directly discharged into space and becomes space junk. This is due to the huge load capacity and low price of Gaoshou Company's aircraft, which eliminates the need for everyone to drink recycled filtered water with a strange smell - to be honest, it is really disgusting.
These space junk will soon fall into the sun or other stars.
Twenty minutes later, the plane began to accelerate again, and its speed gradually exceeded 50 kilometers per second.
"Everyone, please note that we have arrived above the moon. We will use the moon's gravity to slow down. Please check your seat belts. The countdown is from 10 minutes to 9 minutes..."
The countdown ends, and gradually a huge centrifugal force acts on everyone, and the direction changes indefinitely, because the plane also flips in space.
The moon in space is not as beautiful as the earth, it is just a gray and pitted world; but now there are some artificial buildings dotted on it, which are fully automated mining bases in space. But these things are very small, usually only a hundred meters in size. Sunrises on the Moon are not as spectacular as on Earth because there is no air to scatter them. Only a dazzling ball of light could be seen rising from the ground - not the rotation of the moon, but an alternative sunrise caused by aircraft circling the moon.
