Wedding night!My vegetative husband suddenly opened his eyes and kissed me

What are gravitational waves?
Gravitational waves were a prediction made by Einstein 100 years ago in his general theory of relativity.

The general theory of relativity believes that as long as it is an object with a non-zero mass, it will cause space-time curvature, and this curvature will form a "field" that extends infinitely outward. All objects, including light, can only move along the geodesic line in this curved space-time. The effect of space-time bending is manifested in the form of gravity.

In this way, Newton's theory of universal gravitation in classical mechanics has been sublimated qualitatively, explaining how gravity comes from the root.According to the theory of space-time curvature, any matter, as long as it has mass, regardless of its size, will cause curvature to the surrounding space-time.

The movement and changes of these substances will cause disturbances to the surrounding space-time, forming circles of ripples like a stone thrown into the water, spreading to the distance. These are gravitational waves, also known as space-time ripples.

This wave does not travel instantaneously, but travels at the speed of light.

But Einstein's prediction has been put forward for more than 100 years, scientists have exhausted all kinds of methods, but they have not detected the existence of gravitational waves.

Because gravitational waves are very weak waves, they are difficult to detect.

In the 70s, Professor Taylor of the University of Massachusetts and his student Hulse observed the phenomenon of twin neutron stars entangled with each other, and used Einstein's theory to accurately calculate the orbital changes of the two neutron stars, thus indirectly confirming the gravitational wave The presence.As a result, they won the Nobel Prize in Physics in 1993, but direct evidence of the existence of gravitational waves has not been obtained.

And now, the question raised by the other party is how to directly confirm the existence of gravitational waves!

It's so hard!

There is simply no solution!
……

"You guys are cheating! This is a century-old problem!" Wang Kai blushed and had a thick neck.

"But the professors in our school discovered indirect evidence of gravitational waves! This shows that in the field of physics, we are still dominated by white people! You yellow people are just picking up the wisdom of others—"

The student on the opposite side was still talking about it, but Su Sa said coldly: "Prove gravitational waves? Is it difficult!"

With that said, Su Sa got off her seat and came to the blackboard in the middle of the stage.

"Su Sa! What are you doing! This is quantum physics! You don't understand! Don't be brave!" Wang Kai yelled.

But Su Sa was unmoved.

"Chief Cheng, take care of me!"

Wang Kai looked at the head of the delegation.

The leader's surname is Cheng.Many people don't know that he is actually the head of the four great families in the imperial capital, the current head of the Cheng family, Cheng Yaozong!
Logically speaking, as Cheng Yaozong, he would not participate in such activities.

But the Cheng family has always loved talents.

Want to recruit young talents.

That's why I chose to lead the team myself.

Because these are the best young people in Huaguo.

During this time, Cheng Yaozong watched with cold eyes, and had a very good impression of Su Sa.

Low-key, restrained, talented, and beautiful.

It's just someone else's child!
Let Cheng Yaozong not only sigh with emotion, if he had such an excellent daughter?
As for Wang Kai?

Arrogant, grandiose, utilitarian.

Cheng Yaozong had a bad impression of him.

Hearing Wang Kai's words now, Cheng Yaozong said coldly: "Academic communication is to speak freely, and you have to allow others to speak out!"

Wang Kai didn't dare to say anything.

But in his heart, he hoped that Su Sa would make a big fool of himself!
Su Sa stood on the stage and talked eloquently: "We can detect gravitational waves through black hole collisions. Black holes are the top extreme celestial bodies in the universe...The energy and gravitational waves erupted by black hole collisions are of course stronger and easier to monitor. It's here... Except for black holes, the source of gravitational waves detected by humans comes from neutron stars..."
