The villain powerful minister pitted his tech house

Chapter 481

"That is...pretend that there is an elastic cloth in front of you, and stretch it straight. This cloth is the field, and an object with a large mass is placed in the center of it, and its depression is the change of the field caused by the mass.

Throw some small balls on the cloth, and the balls will spin and fall down along the depressions.

You understand this.

This is the reason why planets revolve around stars, and this is also the effect of gravity.

It is also because of the revolution of the planets that spring, summer, autumn and winter and different temperature zones are produced. "

Song Shushu looked at him with bright eyes, "Do you understand?"

In fact, Fu Xuan didn't understand it very well, and felt that if he said he didn't understand at this time, he would be disgusted by Shushu. It was the first time that His Majesty learned the inferior behavior of pretending to understand, "Well, this gravitational force is really powerful."

"Of course it's great." Song Shushu said excitedly, "Is the concept of time clear?"

"It's natural." Fu Xuan nodded, even if he hadn't watched those Enlightenment TVs, he was quite clear about it.

The plan for a day lies in the morning, and the plan for a year lies in the spring.

This is what the ancients said, to cherish the famous aphorism of time.

"That's fine." Song Shushu stroked in the air, and "swimmed" to the vicinity of Fu Xuan like a frog. "According to research, the magnitude of gravity can also change the flow rate of time."

"Gravity can change time?" Fu Xuan's mind was buzzing.

"That's right." Song Shushu nodded, "When the gravitational force is stronger, the relative time flow will slow down."

"Time will change?" Fu Xuan began to diverge his thoughts, "Wouldn't it be possible to live forever in a place with a huge gravitational force?"

"It's a good idea." Song Shushu smiled mockingly, "This slowing down of time is relative. There was once a great man named Albert Einstein, who proposed an extremely important theory - the theory of relativity.

One of the important theories states that the speed of light remains constant under any circumstances.

What does this mean? If there are two people, A and B, they both live on the same planet.One day A got a spaceship, went on an interstellar journey, and flew to another planet.The gravitational force of this planet is a hundred times that of the original planet, stay on it for an hour or two, and then fly back to the original planet.

At this time, the time of A and B are compared respectively.From A's point of view, the time has only passed a few hours; but from B's point of view, or the original planet, years or even decades have passed. "

Song Shushu looked at Fu Xuan, did you understand?
Fu Xuan pondered slightly, "It's a bit like the fairy tale of 'one day in the sky, one year on the earth'."

"Yeah!" Song Shushu nodded, "It kind of means that."

Song Shushu looked up, pawing and pawing in the air with his limbs and claws.

"In addition to gravity, speed can also change the flow of time. The faster the speed, the faster the flow of time." Song Shushu continued, "The proof is relatively simple.

As early as the earth period, some people did experiments with two cesium ion clocks.Put them on the ground one by one, and fly one around the earth on a supersonic plane.

Compared with the final results, the cesium ion on the plane is slower than that on the ground by a full second. "

Song Shushu looked at Fu Xuan, and said slowly, "Isn't it amazing?"

Fu Xuan looked at Song Shushu and nodded seriously, "Are all the people there so powerful?"

"No, there are also idiots like Ye Feixin."
