The spacious lecture hall was silent, with only Zhou Xing's voice echoing.
"The propagation of 'waves' requires a medium. In different environments, the propagation form and speed of 'waves'... each has its own characteristics. The collapse of space and time due to its own weight produces gravitational waves... The universe is the space closest to vacuum, and the density of matter is about 2-5 atoms/m3. In this environment, the propagation range of gravitational waves is the farthest, the period is the longest, and the intensity is the weakest... "
"We set the variable value of the propagation medium as: Z, and define the mass of the wave source as: S... Wavelength A, k is the wave vector, x is the space-time coordinate... Substitute the above equation into the wave equation: Kx2+ky2+kz2-k02/ c2=0."
"dE is the energy differential, dt is the time differential, -dE/dt is the rate of change of energy decreasing with time... The perturbation caused by the weak gravitational field, the Riemann tensor calculated under this metric... "
"Next, we start to derive the gravitational wave equation... "
“…”
Gravitational waves are a phenomenon in which perturbations in the curvature of space-time are transmitted outward in the form of traveling waves. They are radiated from stars or galaxies. They are fluctuations in space caused by changes in the mass and speed of space.
As early as 1915, Einstein proposed the existence of gravitational waves and predicted that strong gravitational field events in the universe would produce gravitational waves.
However, the fluctuation signal of gravitational waves is too weak to be observed.
During 1974, other scientists indirectly discovered the existence of gravitational waves. In 2016, the existence of gravitational waves was directly proved for the first time. An inspiration flashed in Einstein's head in two seconds. It took humans 100 years to prove it.
Now, the special wave theory of everything has further improved the theory of gravitational waves.
Under Zhou Xing's explanation, the experts and professors in the front row were fascinated, and the students from the engineering college in the back row were all drowsy. The content of the special wave theory of all things - gravitational waves was too profound. , they quickly lost their understanding.
Forty minutes passed, and almost half of the audience in the audience could hardly open their eyes.
Because of Zhou Xing's reputation, this opportunity to listen to the lecture was very rare. They all kept their spirits up, their eyes dull, and listened for days like years.
Faced with this situation, what can Zhou Xing do? He is also very helpless!
Engaging in science is inherently a highbrow thing, not to mention that The Theory of All Things Tebo is a profound paper in the field of basic science. The content is profound and complex, and it is impossible to understand it without relevant knowledge reserves.
"That's it for the gravitational waves. Next, I'll start explaining biological waves." Zhou Xing sighed and ended the narration on gravitational waves, preparing to explain the content of biological waves in other ways.
"Teacher Zhou, we haven't talked about the curve equation behind gravitational waves yet!"
"Yes, Teacher Zhou, you haven't finished explaining the force field effects of gravitational waves yet."
"Teacher Zhou, can you tell me again the process of defining the formula for the relative action of gravitational waves? This question is difficult to understand!"
“…”
As soon as Zhou Xing finished speaking, the experts and professors who were listening attentively stopped and shouted anxiously, "The theory of special waves of all things - gravitational waves haven't been finished yet!" How can I talk about biological waves? Who will answer the rest of the knowledge for them
"I'm really sorry. Due to time constraints, I can't explain all the contents of Tebo Theory of All Things today. I can only select some key knowledge to explain. Please forgive me." Faced with the sudden commotion in the audience, Zhou Xing smiled slightly and said nonchalantly.
After speaking, Zhou Xing ignored their reactions and continued his speech: "Before talking about biowaves, let me talk about bioelectricity first, because the two are closely related."
"Bioelectricity refers to the potential and polarity changes that occur in biological organs, tissues and cells during life activities. It is a normal physiological activity manifestation of a type of physical, physical-chemical changes during life activities, and is also a component of biological living tissues. Basic Features."
"Biological waves: various rhythmic fluctuations that occur in biological organisms, which are necessary for all organisms to maintain normal operation. Cells produce regular fluctuations during the process of growth and division. Through this fluctuation, energy is absorbed and used , and then excrete the waste produced by metabolism, thereby ensuring the normal functioning of the organism."
"You can understand it this way, bioelectricity is the process of biological activity, and biowaves are the result of biological activity." Zhou Xing concluded.
I understand this!
Hearing this, the originally listless students suddenly looked at Zhou Xing with a bright look.
Seeing this, Zhou Xing smiled slightly and continued to explain: "Compared to gravitational waves, the application of biological waves is more promising."
"Animals on Earth can be divided into two categories, one is ectothermic animals, and the other is endothermic animals. Compared with ectothermic animals, endothermic animals have a wider range of activities. However, ectothermic animals have a good characteristic that is worthy of our use. ." Zhou Xing looked at the audience and said with a smile.
Hearing this, everyone in the lecture theater pricked up their ears and showed great interest. The content Zhou Xing was explaining now was much more interesting than the boring knowledge about gravitational waves. Even the experts and professors were like this, with bright eyes. Look at him and wait for the rest.
"Snakes are cold-blooded animals. When the temperature drops in winter, they must hibernate to reduce energy consumption." Zhou Xing said with a smile.
Hearing this, the audience nodded incessantly. Snakes are cold-blooded animals, and the temperature in their bodies changes with changes in the ambient temperature. In winter, when the outside temperature drops, the snake's body temperature also drops, and its movements are slow and unable to catch prey. Therefore, the snake Humans must hibernate to adapt to low temperature environments.
But why did Zhou Xing use this example? What are the advantages of this feature
The audience looked at Zhou Xing on the podium with confusion and confusion.
"After a snake hibernates, its metabolism decreases. If we can use biological waves to change the body's thermostatic system, can we create a hibernation chamber with a long-lasting mechanism?" The audience asked in confusion. Eyes, Zhou Xing explained with a smile.
Without waiting for the audience's reaction, Zhou Xing straightened his face and continued to explain in an exciting tone: "According to the current speed of scientific research and the application potential of biowaves, in about 30 years, we can develop biotechnology that breaks the limit of human lifespan, and I am confident that I will develop this cryogenic sleep chamber within a year, and it is expected to slow down the metabolic rate of humans by more than 10 times."
"In the next stage, Shining Star Group will launch the cryogenic hibernation chamber project and invest heavily in finding biotechnology that will break the limit of human longevity. Compared with the vast universe, human lifespan should not be just a hundred years." Zhou Xing looked at it with a smile on his face. The audience in the audience solemnly announced.
The audience in the audience was stunned for one second, two seconds, three seconds. They looked at Zhou Xing dreamingly, as if they had seen a ghost, and they were collectively lost.
