"It's not moving. ”

Chen Yu's voice fell, and the barrage broke out again.

【？】

【？？？】

[Qiao Biluo: Yes, it didn't move. It's me who moves. 】

[Motionless is the eighth king.] 】

[How can you exceed the speed of light if you don't move?Do you rely on love?]

[The speed of light depends on fate, and fate will naturally be superceed. 】

[Immovable and exquisite. 】

[One punch, one particular ......]

In order to watch this wave of barrage from the audience, Chen Yu deliberately took off his hand armor, stared at his watch for a while, and found that the entire screen was black, so he had no choice but to give up: "There are too many barrages, and I can't see them clearly when they overlap together." But even if I don't look at it, I can know what people are saying. If a spaceship doesn't move, how can it exceed the speed of light?"

"The relevant principles are complex and complex, simple and simple, and I try to use easy-to-understand language to solve your doubts and feel the magic of future technology. ”

"First of all, there is a premise that the speed of light is unbreakable in the theory of relativity, and this must be made clear. ”

"The speed of light is the maximum speed at which an object moves. According to the well-known mass-energy conversion formula: e=mc2, e stands for energy, table mass (mass), and c stands for constant. When the speed of an object reaches a quarter of the speed of light, its mass increases as the speed increases! ”

"If the object continues to accelerate to close to the speed of light, which is 300,000 kilometers per second, its mass will tend to infinity. ”

So, according to this formula, an object with mass can never, ever reach or even exceed the speed of light. This is the premise that the speed of light is unbreakable, and objects with mass are unbreakable!"

"And the reason why the photon is so fast is only because the mass of the photon is all converted into energy, which exerts the speed to the extreme. ”

Stretching out a finger, Chen Yulang said: "According to this premise, objects with mass cannot exceed the speed of light, so conversely, can objects without mass exceed the speed of light?"

The answer is...... Yes. ”

"As long as it does not carry mass and information, faster-than-light is allowed. For example, the wave function of quantum mechanics, tachyons, and the expansion of the universe! These are the most typical examples. ”

"The universe was born and the Big Bang 13.8 billion years ago, but the universe is much more than 13.8 billion light-years, which means that space expands faster than the speed of light. Moreover, since the expansion of space does not carry information, it does not violate the theory of relativity, and the speed of light is reached. ”

Speaking of which, some viewers should have guessed how the spaceship was going to be faster than the speed of light. ”

"Yes. Chen Yu nodded, and his voice became excited: "The spaceship does not move, but it controls the space around the spacecraft to move! Because the expansion and contraction of space does not carry information in nature and allows the speed of light, the spacecraft that is 'wrapped' in space also moves with the movement of the space that shrinks and expands, and then exceeds the speed of light!"

"This is the principle of the superluminal speed of spaceships!"

【it!】

[I'm also +1]

[Dumbfounded......]

[Can you still steal chickens like this?]

[A little confused, is there a big guy to explain in detail?]

[It's simple.] It is a change in space, shrinking the space in front of the spaceship and expanding the space behind it, dragging and pushing one by one, wrapping the spacecraft around. 】

【Show ......】

[I still don't understand that the space is wrapped around the spaceship, isn't it also a carrying of information?]

[There is no information carried, this is just a simple change in space, and the spaceship wrapped in it has not moved at all.] If this is also considered to be carrying information, how can those stars at the edge of the universe move away faster than the speed of light?]

[A bit like curvature sailing?]

[It's different, curvature navigation is to find a way to reduce the curvature of the rear and let the curvature of the front be dragged with a greater curvature. This way the up master said has nothing to do with curvature, exaggerated to describe it, it belongs to pulling the universe in front and pushing out the universe behind. The distance between the universe and the universe remains the same, except that the spaceship has been removed. 】

[It's scary to hear, where did you get so much energy......]

"Where did you get that much energy?"

Facing the camera, Chen Yu spread his hands: "There will definitely be viewers who ask like this, and the number will not be small." This proves that your mind is still at the level of 'energy drive'. Of course, this does not mean that you are stupid, on the contrary, being able to take into account the energy aspect means that the mind is excellent. The difference is simply the difference between the perception of modern humans and future humans, which leads to limited thinking and always stays within the framework of knowledge in the 21st century. ”

"We all know that the ship doesn't move, it only moves space. The change in space does not actually need to consume the energy currently used by humans. These include hydrogen, antimatter, planetary energy, stellar energy, and even black hole energy...... None of them are needed. ”

"There is only one thing that changes the space. It's called dark matter. ”

After the words fell, Chen Yu stood up and pulled a piece of mahogany from the chair, which turned into red chalk.

He first adjusted the camera, then crouched down and quickly wrote a series of words on the ground with chalk: "What is dark matter?" It was first proposed by astronomer Jacobus Kapteyn in 1922. But until 2021, it has not been directly detected by humans, and only some possible real evidence has been used to prove this substance. ”

"Congratulations Kaptan, your theory is right. Dark matter does exist. And ......"

Raising his hand, Chen Yu pointed to the ball on the left: "It's in the ball on the left side of this spaceship!"

According to the conjecture analysis of dark matter in the twentieth century, the following properties are obtained. ”

"One, dark matter is involved in gravitational interactions. Maybe it's quality. ”

"Two, dark matter should be highly stable. ”

"Three, dark matter does not participate in electromagnetic interactions, let alone photon interactions, so we can't see them. ”

"Fourth, dark matter should move much faster than the speed of light, otherwise the universe would not have been able to form such a large-scale structure under the action of gravity. ”

Standing up, Chen Yu rubbed off the "three" with his foot and said, "I have fused the tutorial information of this spaceship and have a general understanding of dark matter. The third is wrong. Dark matter interacts with photons, but only very weakly. ”

"In addition to the correct three properties, dark matter has two important properties. One, it causes the universe to shrink. Two, it's evaporating. ”

"What I mean by evaporation is just an adjective, or more precisely, it's undergoing an unknown reaction that is dissipating an energy body called dark energy. This energy body has an unimaginable amount of negative pressure and negative energy. It is this energy that causes the expansion of the universe!"

"That's right, the global physics and astronomical community, now update your models of the universe and your textbooks. It can be determined that dark matter is disappearing because it is constantly generating new dark energy, more and more. This also explains why the universe is expanding faster and faster. ”

Throwing away the chalk, Chen Yu opened his arms to the camera: "In this regard, everyone should be clear about how the faster-than-light spacecraft changes space." ”

"The left ball of the spacecraft contains a large amount of compressed dark matter. The right ball is vacuum. ”

"When the spacecraft enters space, the ban on the sphere on the left side is turned off, and the dark matter shrinks into the space on the left side by means of (symbols that cannot be entered). ”

At the same time, the spacecraft will decompose a part of the dark matter into dark energy, which will be introduced into the sphere on the right side and expand the space on the right. ”

"When the attitude of the spaceship changes to the left ball forward, the right ball backwards, as soon as it closes and rises, the spacecraft will move faster than the speed of light! No matter how fast the movement is, it will not produce any acceleration, and it can accelerate from 0 to hundreds of times the speed of light in one second, or even one microsecond!"

"Science and technology have finally defeated the universe. ”
