Chapter 517

Lena's words seemed to throw a stone into the original calm lake. Since then, the smooth surface of the lake has been rippled and no longer smooth.

"Is time and space distorted?"

If your excellency bragus understood, he would repeat what Lena said.

"In the original theory of relativity, space-time should be flat, which can explain the speed of light, but the observation of light bending in the gravitational field makes relativity incomplete."

Lena said he waved his hand and the light formed a simple galaxy, a pattern of a planet orbiting a star.

"In the past, we thought that gravity was the mutual attraction between objects, just like a rope connecting two objects."

With Lena's words, a thin line extends from the star and connects with the planet, which is like the planet being dragged by the star.

"This is the mode of gravitational action in flat space-time. We can see that if we follow this way, for objects in remote places, gravity will need a certain amount of time to act, and the operation of stars in the whole universe will present a very chaotic mode."

There is a continuously running light cluster on his hand. This is his calculation matrix. After a period of calculation, he calculated the celestial body system of one star and three planets. Substituting the concept of gravitational velocity, we can see that its operation is extremely irregular, which is quite different from the observation situation.

"Then we either assume that gravity takes no time and exceeds the speed of light, which is contrary to relativity, or we assume that gravity is not an interaction in the usual sense."

Lena snapped his fingers, and the disorderly and irregular movement of the stars stopped immediately.

On this plane, Lena reaches out and gently pulls down.

He creates a depression in the plane of the star, which is like a heavy iron ball falling on a flat cloth. Due to the mass of the star, the whole plane is distorted.

Next, Lena cut the connection between the star and the planet.

With a snap of a finger, the whole celestial system is working again.

At this time, the mages were surprised to see that the planets move towards the star due to the depression of the plane, and the planets move forward at their own speed. The two constitute a perfect balance, making the motion of these planets around the star form a perfect and regular motion mode.

"This is just a demonstration image. The real distortion of four-dimensional space-time is not so simple, but it can also reflect my conjecture."

All the mages were silent as they looked at the star map spinning on the sunken plane.

"Time and space are not flat. All objects with mass will cause space distortion. The greater the mass is, the greater the distortion will be. I turn the degree of space distortion into curvature. In this way, I can explain why light deflects around objects with mass."

Lainer explained.

"In the original theory of relativity, light always moves along the shortest path between two points. In the view of gravitational deflection, this seems to be incorrect. However, if a large mass object causes the bending of space-time, it can solve this problem. That is, light always moves along the shortest path, but it can't penetrate space-time and can only move when it is twisted It's moving in the air, so in our opinion, it's causing light deflection! "

"At the same time, the distortion of space-time also explains the transmission of gravity. The reason why the transmission of gravity can surpass the speed of light is not that it spreads very fast, but because gravity does not need to spread at all. The essence of gravity is the interaction brought about by the bending of space-time caused by massive objects!"

Lainer said that the computing array around him is running fiercely. This is the deflection angle of light after adding space-time distortion to the calculation.

Soon, Lena got his answer and showed it to the public.

Its value is almost the same as the observed value, which is double the calculated value according to the original law of gravitation!

"... the distortion of time and space..."

if your excellency Alberton has realized something, his brain is also calculating.

If space is not flat, if the existence of objects will affect space, if gravity is really caused by the distortion of space-time...

"this can explain why time becomes slower around massive objects, because when light keeps the same speed around these objects, it needs to move more slowly in the distorted space-time More time, therefore, the passage of time becomes slower....

Mr. Alberton has solved a problem that has plagued mages since the theory of relativity was put forward, that is, why the flow of time slows down in a strong gravitational field.

"Wait, according to this inference, can we assume an extreme situation, that is, when the gravitational field is large enough to a certain value, the speed of light will travel in it for a longer time, too long to escape?"

Mr. Braggs's words were like thunder, which brought a bolt from the blue to Mr. Alberton and Mr. fielder."We can calculate it."

Lena immediately began to calculate, and then, other mages also substituted in the numerical value and performed the calculation.

This process lasted for half an hour, and the whole control room was silent.

Phyllis looks at them. Although she can't really understand them with his level of magic theory, Phyllis can feel that these mages seem to have discovered some secrets of the world. She looks at Lena and feels that Lena, who is calculating and deducing carefully at the moment, has a completely different charm from the usual.

Finally, Lena was the first to get the result.

The results show that when the maximum mass is concentrated on a small point, it will produce a very strong space-time distortion, making a region around the point, in which light can not escape, which means that the horizon around the singularity will be really dark.

At the same time, the singularity will cause a series of relativistic effects, including that the time near the singularity will be greatly delayed. On the event horizon surface, the external observer will even observe that time is still. At the same time, the strong gravity of the singularity will lead to the distortion of the light of nearby galaxies. In short, the values of some mathematical constants on these galaxies may change There is no change.

This singularity is like an abyss that devours everything. Even the fastest light in the universe can hardly escape from it.

"Such a singularity, I think, can be called a black hole."

Said Lena, looking out at the distortion of space in the light of the searchlight.

"The past theory of relativity should also be revised, from the original special theory of relativity to the present general theory of relativity."
