Chapter 516

For a moment, Mr. Alberton felt that the world had become unreal.

The basis of mages' theory comes from observation, while human observation mostly relies on vision.

Now, they find that light will be bent by gravity, which means that the original observation data must take into account the influence of gravity. In a low-speed and small world, the value of gravity is very low, and it can be approximated. However, in a macro high-speed world, especially when it comes to the laws of the operation of stars, the influence of gravity can not be ignored.

If light really bends because of gravity, there will be huge errors in the observation data of planets at present. All the theorems, including the three laws of Reagans, will be overturned and rewritten, and the three laws of kinematics, the cornerstone of your promotion to legend, may also deviate.

Mr. Alberton felt shaken and did not dare to think further, for fear that these thoughts would lead to cognitive instability and collapse.

Mr. Braggs saw the trouble of Mr. Alberton. He carefully observed the bending laser and thought for a long time before he said.

"According to Ian Gray's uncertainty principle, we can't measure the position and momentum of a particle at the same time. Therefore, we originally thought that light was a mass free object, so it would not be affected by gravity, but now it seems that this theory is somewhat biased."

He thought about it, took a look at Lena, and then continued.

"To be exact, light has no rest mass, but momentum only when it moves."

Lena nodded slightly.

It's easy to understand.

The energy of the released light is different when the electron in the atom transits in different energy level orbits. The energy follows Stein's formula e = HV. If the light has a static mass and the light quality of different frequencies is different, then the energy of the moving photon e = 12mv ^ 2, the speed of the photon will be different because of the different mass, but in fact it is The speed of light is constant and there is no deviation, so the photon has no rest mass.

This is consistent with the deduction of Lennar's mass energy conversion equation. Mass is a form of energy, which is precisely a measure of the inertia of an object. Therefore, photons can be regarded as particles that are not constrained by inertia. In fact, light only has energy, but not static mass.

Because of this, light will be affected by gravity and deflect.

"It's just that..."

Your Excellency Bragg's words changed and began the calculation process. Countless lights flowed in the control room and turned into equations.

Soon, the calculation was over, but Mr. Bragg's expression was more dignified than relaxed.

"According to the calculation results, if the three laws of kinematics and the gravitational formula are applied, then the deflection angle calculated is this value."

With a wave of his hand, a simplified calculation is presented.

"But actually, the observed deflection angle is this value."

After careful calculation, the value of light deflection angle also appears in your hand. You can see that the actual measured value is almost twice the value calculated by the gravitational formula, which can not be explained by error.

"There seems to be some twists and turns we don't know about."

Lord Braggs closed his eyes and seemed to be thinking.

At this time, at the bottom of the silent big hole, the abyss diver is located outside the gate of the nether world. Although there is no threat of the invisible monster, the things that make the mages feel more scared are lingering.

"Actually."

After a long time, Lena cleared his throat and said, making the rest of the people look at him.

Lena put forward the theory of relativity, which solved many problems related to the speed of light, but now it seems that this theory is not perfect.

In fact, after the theory of relativity was put forward, although many observation results conform to Lennar's prediction, there are also some that do not conform to the prediction, but the deviation is relatively small, and the explanation given by many mages is the error of observation means.

Now it seems that this may be related to the deflection of light under the influence of gravitational field.

"After I put forward the theory of relativity, there has always been a doubt, that is, how gravity spreads."

At the beginning of Lena's words, the mages were still a little confused, but soon they realized the problem in Lena's words, and all of them showed surprise.

"Yes, if the speed of light is constant and cannot be surpassed, then the propagation of gravity should be time-dependent, that is to say, gravity is not an instantaneous effect, but needs to be propagated."

Mr. Alberton said suddenly.

This means that the gravitational force between the sun and the planet on the main plane will take several minutes to reach, because the speed of gravity cannot exceed the speed of light.

Substituting this point into the current astrology theory, the result is inconceivable and contrary to the experimental observation.

But if we think that the propagation of gravity does not need time, it will violate the hypothesis that the speed of light in relativity cannot be surpassed."Gravity itself is a kind of information. It can't exceed the speed of light under the framework of relativity, so there is a huge contradiction. Lena, you thought about this before?"

Field looks at Lena. This young high-level mage is growing up step by step, but he didn't expect that he had thought so far. I'm afraid that now, in terms of academic level, field is not as good as Lena.

"I had some thoughts before, but I couldn't find a solution, so I didn't put it forward systematically. Until now, we realized that light would bend because of the existence of gravitational field, which made me have a new idea."

Said Lena, looking out of the glass window at the door of the nether world, which loomed in the light, and then opening his mouth.

"First of all, gravity is not an electromagnetic force. To be exact, gravity is not a force."

Leiner's words made Mr. Alberton's eyes wide open. In his decades of research, gravity has always been one of the basic forces and the basis of his research, but now Leiner even says that gravity is not a real force?

"What did you say, Lena?"

Mr. Alberton asked uncertainly, asking Lena to repeat what he had said.

"Gravity is an interaction, which does not originate from the mutual attraction of matter, but from the distortion of space-time, that is to say, your excellences..."

lenaton said later.

"The space-time we live in is not flat, but distorted. Just like the space around the gate of the nether world, it is this distortion that produces gravity and deflects light."
