The spacious lecture hall was silent, only Zhou Xing's voice was echoing.

"The propagation of 'waves' requires a medium, and in different environments, the propagation form and speed of 'waves' ,...... , each with its own characteristics, the celestial bodies due to the collapse of their own weight in space-time and space to produce gravitational waves,...... , cosmic space - the closest space to a vacuum, the density of matter is about 2-5 atoms/m3, in this environment, gravitational waves propagate the farthest distance, the longest period, and the weakest intensity,......。 ”

"We set the variable value of the propagation medium to: Z and the mass of the source body as: S,...... , wavelength A, k is the wave vector, x is set to the space-time coordinate,...... , substituting the above equation into the wave equation: Kx2+ky2+kz2-k02/c2= 0. ”

"dE is the energy differential, dt is the time differential, and -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 gauge,......。

"Next, we started deriving the gravitational wave equation,......。 ”

“……。 ”

Gravitational waves, a way in which the perturbation of the curvature of space-time is transmitted outward in the form of traveling waves, a phenomenon that radiates out of a star or galaxy, resulting in fluctuations in space due to changes in the mass and velocity of space.

As early as 1915, Albert Einstein proposed the existence of gravitational waves and predicted that gravitational waves would be produced by strong gravitational field events in the universe.

However, the wave signals of gravitational waves are too faint to be observed.

During 1974, other scientists indirectly discovered the existence of gravitational waves, and in 2016 the first direct proof of the existence of gravitational waves occurred in Einstein's head for two seconds, and it took mankind 100 years to prove it.

Now, the theory of gravitational waves has been further refined by the theory of gravitational waves.

Under Zhou Xing's explanation, the experts and professors in the front row listened fascinated, and the students in the back row of the College of Engineering listened drowsy one by one.

More than 40 minutes passed, and almost half of the audience was almost blind.

Because of Zhou Xing's fame, this opportunity to listen to the lecture was very rare, and they all held on to their spirits, their eyes were dull, and they listened like a year.

In the face of this situation, what can Zhou Xing do? He is also very helpless!

Engaging in science is inherently a matter of high and low, not to mention, the theory of all things 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 gravitational waves, and now I'm going to talk about biological waves. Zhou Xing sighed, ended the narration of gravitational waves, and prepared to explain the content of biological waves in other ways.

"Mr. Zhou, the curve equation behind the gravitational wave hasn't been talked about yet!"

"Yes, Mr. Zhou, you haven't finished talking about the force field effect of gravitational waves. ”

"Mr. Zhou, can you explain the process of defining the formula for the relative action of gravitational waves again?

“……。 ”

As soon as Zhou Xing's voice fell, the experts and professors who were listening to it stopped doing it and shouted anxiously one after another, "The Theory of Terte-Wave Theory of All Things-Gravitational Waves has not yet been finished! How can they skip talking about biological waves? Who will answer the rest of the knowledge for them?

"I'm really sorry, due to time constraints, today I can't explain all the contents of the theory of all things, I can only pick some key knowledge to explain, and I ask for your forgiveness. In the face of the sudden riot in the audience, Zhou Xing smiled slightly and said disapprerovingly.

After speaking, Zhou Xing ignored their reactions and continued to speak: "Before talking about biowaves, I will talk about bioelectricity, because the two are closely related. ”

"Bioelectricity, the potential and polarity changes of organism, tissues and cells in the process of life activities, it is a normal physiological activity manifestation of a class of physical, physico-chemical changes in the process of life activities, and it is also a basic feature of biological living tissue."

"Bio-waves: all kinds of rhythmic fluctuations that occur in biological organisms, which are necessary for the normal operation of all organisms. ”

"You can understand it this way, bioelectricity is the process of biological activity, and biological waves are the result of biological activity. Zhou Xing concluded.

This one understands!

Hearing this, those students who were originally listless looked at Zhou Xing's gaze with a hint of brilliance.

Seeing this, Zhou Xing smiled slightly and continued to explain: "Compared with gravitational waves, the application of biological waves is more promising. ”

"The animals of the earth can be divided into two categories, one is ectothermic animals and the other is homeotherms, compared to ectotherms, homeotherms will have a wider range of activities, however, ectotherms have a good characteristic worth using. Zhou Xing looked at the audience and said with a smile.

Hearing this, everyone in the lecture hall pricked up their ears, full of interest, the content that Zhou Xing is explaining now is much more interesting than the boring knowledge of gravitational waves, even those experts and professors, looking at him with bright eyes, waiting for the following.

"Snakes are ectotherms, and when the temperature drops in winter, it has to hibernate to reduce energy consumption. Zhou Xing said with a smile.

Hearing this, the audience nodded endlessly, snakes belong to cold-blooded animals, the temperature in the body changes with the change of environmental temperature, in winter, after the outside temperature drops, the body temperature of the snake also drops, and the slow action can not catch the prey, so the snake must take the way of hibernation to adapt to the low temperature environment.

However, what does Zhou Xing do with this example? What is there to use this feature for?

The audience looked at Zhou Xing on the podium in confusion, with a blank face.

"After the snake hibernates, its metabolism decreases, if we can use biological waves to change the body's thermostatic system, then can we create a long-term mechanism of hibernation pod?" Zhou Xing explained with a smile in the bewildered eyes of the audience.

Without waiting for the audience's reaction, Zhou Xing's face was straight, and he continued to explain in an impassioned tone: "According to the current speed of scientific research and the application potential of biological waves, in about 30 years, we can develop biotechnology that breaks through the limit of human lifespan, and I am sure that this kind of low-temperature hibernation cabin will be developed within a year, and it is expected to delay the life span of human beings by more than 10 times." ”

"In the next stage, Xingyao Group will launch the low-temperature hibernation chamber project and invest heavily in finding biotechnology that breaks through the limits of human longevity, and the human lifespan should not be just a hundred years. Zhou Xing looked at the audience with a smile on his face and solemnly announced.

The audience in the audience was stunned, for one second, two seconds, three seconds, they looked at Zhou Xing stupidly, as if they had seen a ghost, and collectively lost their minds.
