Interstellar Immortality: Live long enough to dominate the universe

"The real graviton."

Ella was so excited that she recorded all the data.

At the end of one minute, Yan Xia was also a little moved by this discovery. He didn't have much hope.

After all, who can think of using gravitational waves to detect gravitons?

Gravitons move with the vibration of space. When matter moves, it will inevitably produce mass. Even if the graviton itself is attached to space, it will not move relative to space as space moves.

But the cleverness of this experiment is that if gravitons exist, how to adjust the size of gravity.

Gravity can spread to an infinite distance and has no boundaries in theory. This is the special feature of gravity.

The existence of gravitons must explain this special feature, that is, gravitons are adjusted by a mechanism, not by the number of other mediators.

This device is designed to capture the tiny changes of gravitons. If it cannot be detected, then it proves that Ella's theory is wrong.

Fortunately, they succeeded.

"Yan Xia, we found the graviton!"

Yan Xia nodded. The discovery of the graviton means the perfection of quantum mechanics.

Of course, this is not yet a grand unification.

The grand unified theory means that the four fundamental forces have a unified source. Now Ella has only discovered that all forces have a medium that transmits the force in the middle.

The medium makes everything in the world bound by the four fundamental forces, so what is the other side of the medium?

"If the graviton exists alone, perhaps we can achieve grand unification more easily." Yan Xia said.

This is undoubtedly a basin of cold water.

They climbed over a high peak and saw the graviton, and also saw a higher peak where the graviton was located. At the same time, there are three other high mountains around this peak.

Some people on Earth say that they have achieved the unification of the three fundamental forces, electromagnetic force, weak nuclear force and strong nuclear force.

But that is not really a real unification. The model created is too arbitrary, just like pointing to a car, a truck, and a sports car and saying that they are all cars.

And the discovery of the graviton is just adding a toy car to it. (The structure of the graviton is different from the other three fundamental forces, and its interaction is also minimal)

They are all cars, of course, but their inner nature is completely different.

Only under certain conditions, these four forces are all symmetrical and become one force, with only one action intensity, can it be called true unification.

This involves another thing.

That is "superstring theory".

Superstring theory is a narrow string theory. Super does not mean super, but supersymmetry.

Superstring theory can perfectly unify the four fundamental forces.

To derive superstring theory, it is necessary to detect the existence of strings.

String theory believes that particles in the universe are not basic units, but smaller strings. Strings form particles through movement. All interactions in the world, all forms of matter and energy, can be explained by the splitting and combination of strings.

The size of energy is also determined by the strength of string movement.

The reason why Yan Xia said that if gravitons exist alone, it would be easier for them to achieve grand unification is also the same. The more similar gravitons are to other particles, the less likely it is to explore smaller strings.

But the reality is that the four fundamental forces are very different, and the strength of the electromagnetic force is 100 trillion trillion trillion times that of gravity.

Even the word "sky-high" seems too small. Even if the earth is only 1 nanometer high, it will be 100 trillion light years away.

"Yes, but Yan Xia, isn't this the charm of science?"

Indeed.

Although Ella has observed the existence of gravitons, it will take a long time before she can really apply gravitons.

Yan Xia originally planned to enter a new round of hibernation, waiting for the day when Ella can make an antimatter device.

But Ella told him something else.

"In the process of detecting gravitons, we need to measure where the center of mass is and create a black hole in the center of mass."

"I collected some data, including Alpha Centauri A and Alpha Centauri B."

"These two stars revolve around the center of mass. If we only observe simple data, it seems that there is nothing."

"But after careful calculations, I found that the center of mass of the two stars should be offset by 70 meters."

The distance of 70 meters in front of the two huge stars is like a wrinkle on a person's clothes protruding one micron.

But after calculation, this exposed a lot of situations.

The mass of the star is wrong.

"You want to say that the things we can't find are likely to be inside the star?"

The third civilization cannot take radioactive elements out of thin air, there must be a device.

Ella has never stopped looking for this device for all these years, but there is no trace.

The device may have beaten all the radioactive elements into microscopic basic units such as strings, so it can escape their detection.

If the source cannot be detected through traces, then other means can only be used.

Ella's discovery is very important.

"Is the problem Alpha Centauri A or Alpha Centauri B?" Yan Xia asked.

The previous data on the screen has been overwritten by new data. It is a triple star system, showing the relationship between Alpha Centauri A, Alpha Centauri B and Proxima Centauri.

"The gravity of the three stars affects each other, which causes Alpha Centauri A and Alpha Centauri B to rotate around the center of mass, but there should be some deviation. After all, the gravity of Proxima Centauri itself is not small, enough to affect two stars so close."

"But I didn't observe this effect, as if the gravity of Proxima Centauri could not shake Alpha Centauri A and Alpha Centauri B at all."

"This is a sophisticated disguise. Alpha Centauri B must have been hollowed out, so that Proxima Centauri just corrected its influence on this binary star system."

"The device we are looking for is most likely in the northern hemisphere of Alpha Centauri B."

It is unimaginable to dig a hole in a star.

The temperature inside Alpha Centauri B may reach 100,000 degrees Celsius. What can exist here, and it seems to maintain a huge hole around it?

"Can our spacecraft enter Alpha Centauri B?"

If they can't enter, then they will have no way to deal with this device.

"Yes!"

"Using the light civilization alloy and internal refrigeration, I can build a spacecraft that can enter the interior of Nanmen II B within 5 years."

"But it can only go 500 kilometers below its surface. The core temperature of Nanmen II B is as high as 17 million degrees Celsius. Going deeper will only melt."

Yan Xia nodded.

"Then I will wait for a while and see what's going on inside Nanmen II B."

This may be the first contact with the third civilization.
