"It didn't move at all."
After Chen Yu finished speaking, the barrage broke out again.
[?]
[? ? ?]
[Qiao Biluo: Yes, it didn't move. It's me who moves.]
[Still motionless is a bastard.]
[How to go faster than light without moving? By love?]
[The speed of light depends on fate. When fate comes, it will naturally exceed it.]
[Be careful about not moving.]
[One punch and one particular monster...]
In order to watch the barrage from the audience, Chen Yu deliberately took off his hand armor and stared at his watch for a while. He found that the entire screen was black and had no choice but to give up: "There are too many barrages, and it is impossible to see them if they overlap. Clear. But even without looking, I can know what everyone will say. How can a spaceship go faster than light if it doesn’t move?”
"The relevant principles can be complicated or simple, and I try to use plain and easy-to-understand language to help everyone understand the magic of future technology."
"First of all, the theory of relativity presupposes that the speed of light cannot be broken. This must be made clear."
"The speed of light is the highest speed at which an object can move. According to the famous mass-energy conversion formula: E=mc, E represents Energy, M represents Mass, and C represents Constant. When the object's moving speed reaches A quarter of the speed of light, and its mass increases as the speed increases further! The faster the speed, the greater the mass of the object.”
"If the object continues to be accelerated to close to the speed of light, which is 300,000 kilometers per second (approximately), its mass will tend to be infinite."
"So, according to this formula, objects with mass can never reach or even exceed the speed of light. This is the premise that the speed of light cannot be broken. Objects with mass cannot be broken!"
"The reason why photons are so fast is because all the mass of photons is converted into energy, which maximizes the speed."
Holding out a finger, Chen Yulang said: "Based on this premise, objects with mass cannot exceed the speed of light. So, conversely, can objects without mass be able to exceed the speed of light?"
"The answer is... yes."
"As long as it does not carry mass or information, superluminal speed is allowed. For example, the wave function of quantum mechanics, tachyons, and the expansion of the universe! This is the most typical example."
"The birth of the universe and the Big Bang 13.8 billion years ago, but the scope of the universe is far more than 13.8 billion light-years. This means that the speed of space expansion exceeds the speed of light. Moreover, since space expansion does not carry information, it does not violate the theory of relativity and exceeds the speed of light. Reached."
"At this point, some viewers should have already guessed how this spacecraft can travel faster than light."
"Yes." Chen Yu nodded, and his voice became excited: "The spaceship does not move, but it controls the movement of space around the spacecraft! Because the expansion and contraction of space do not carry information by nature and allow super-light speed, so the space 'wrapped' in the space The spaceship also moves with the contraction and expansion of space, and then exceeds the speed of light!"
"This is the principle behind the super-light speed of a spaceship!"
[Fuck!]
[I am +1 too]
[Stupefied...]
[Can you still steal a chicken like this?]
[I’m a little confused. Can anyone explain it in detail?]
[Very simple. It is a change in space, shrinking the space in front of the spacecraft, expanding the space behind it, pulling and pushing, wrapping the spacecraft around.]
[show…]
[Some people still don’t understand. The space surrounding the spacecraft also carries information, doesn’t it?]
[There is no information carried. This is just a simple change in space. The spacecraft contained in it has not moved at all. If this counts as carrying information, how do those stars at the edge of the universe move away faster than the speed of light?]
[A bit like warp navigation?]
[Different, curvature navigation is to find ways to reduce the curvature at the rear and let the greater curvature at the front drag. The method mentioned by UP has nothing to do with curvature. To exaggerate it, it means pulling the front universe in and pushing out the back universe. The distance between the front and back universe remains the same, only the spacecraft is moved away.]
[It sounds scary, where does it come from so much energy... ]
"Where does it come from so much energy?"
Facing the camera, Chen Yu spread his hands: "There will definitely be viewers asking this, and the number will not be small. This proves that your thinking is still at the level of 'energy stimulation'. Of course, this does not mean that you are stupid. On the contrary, you can Considering the energy aspect, it represents excellent thinking. The difference is just that the insights of modern humans and future humans are different, resulting in limited thinking, always staying within the knowledge framework of the 21st century."
"We all know that the spacecraft does not move, only space moves. And the change of space does not actually require the consumption of energy currently used by humans. Including hydrogen, antimatter, planetary energy, stellar energy, and even black hole energy... none of them need."
"There is only one thing that changes space. Its name is dark matter."
After saying this, Chen Yu stood up and grabbed a piece of mahogany from the chair, which turned into red chalk.
He first adjusted the camera, then squatted 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 Human beings have directly detected this substance and only used some evidence that may be real to prove this substance."
"Congratulations Kaptan, your theory is right. Dark matter really exists. 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!"
“Based on the analysis of human conjectures about dark matter in the 20th century, the following attributes have been obtained.”
"One, dark matter participates in gravitational interactions. Maybe it has mass."
"Two, dark matter should be highly stable."
"Third, dark matter does not participate in electromagnetic interaction, let alone the interaction of photons, so we cannot see it."
"Fourth, the movement speed of dark matter should be much lower than the speed of light, otherwise the universe cannot form such a large-scale structure under the influence of gravity."
Standing up, Chen Yu rubbed "three" off with his foot and said: "I integrated the tutorial information of this spaceship and got a rough understanding of dark matter. Three is wrong. Dark matter interacts with photons, but it is very weak. .”
"In addition to the three correct properties, dark matter also has two important properties. One, it makes the universe shrink. Two, it evaporates."
"The evaporation I am talking about is just an adjective. To be more precise, it is performing an unknown reaction, dissipating an energy body called dark energy. This energy body has unimaginable negative pressure and negative energy. It is this energy that causes the expansion of the universe!”
"Yes, the global physics and astronomy community, please update your universe models and textbooks now. It is certain that dark matter is disappearing because it is constantly generating new dark energy, more and more. This also explains the speed of the expansion of the universe. Why is it getting faster and faster?”
Throwing away the chalk, Chen Yu faced the camera and opened his arms: "At this point, everyone should know how the super-light spacecraft changes space."
"The left sphere of the spacecraft contains a large amount of compressed dark matter. The right sphere is a vacuum."
"When the spacecraft enters space and closes the restriction on the sphere on the left, through (unable to enter symbol) method, the dark matter will shrink the space on the left."
"At the same time, the spacecraft will decompose part of the dark matter into dark energy, introduce it into the sphere on the right, and expand the universe on the right."
"When the attitude of the spacecraft is changed to the left ball moving forward and the right ball moving backward, and then rising and falling, the spacecraft will move forward at super-light speed! No matter how fast the movement is, it will not produce any acceleration, even for one second, or even one microsecond. , can accelerate from 0 to hundreds of times the speed of light!”
"Technology has finally defeated the universe."
