A star system, a binary star system with two stars revolving around each other quietly releasing light and heat, this is a world shrouded in deep blue and blazing white, 5 planets, 49 moons, like jewels in this dream world, bringing wonderful beauty to the entire star system. Pen? Interesting? Pavilion wWw. ｂiquge。 ｉｎfo

And now, this beauty is starting to change.

In the star system, there are some small points of light that move around the galaxy at a slow speed, and the number of these points of light is so huge that the stellar light they reflect can even bring another piece of starry sky to this galaxy that is not inferior to the Milky Way.

It is a piece of light sail floating in a galaxy of water commissions, a kind of spacecraft that uses the light pressure of the stars to sail through space, they do not have any power system of their own, but because of the presence of two stars, they can continue to interact until their own structure is damaged or the star is extinguished.

As early as the 17th century, the famous astronomer Kepler conceived the possibility of using spacecraft to travel through space without carrying any energy and relying only on the energy of sunlight. Because light is made up of photons that have no static mass but momentum, when a photon hits a smooth plane, it can change the direction of motion like a ping-pong ball bouncing off a wall, and give the impacting object a corresponding force. Using this force, it is possible to create a "light sail" that is accelerated entirely by the momentum of light.

The thrust produced by a single photon is extremely small, and at the distance from the Earth to the Sun, the thrust generated by light on a square meter of sail is only 0.9 dynes, which is less than the weight of an ant. In the case of the Shuiwei-1 star system, there are two stars that are 100 or 1,000 times brighter than the Sun, which brings enough impetus to the operation of the light sails.

In space where there is no air resistance, this small thrust can still provide about 10e-5~10e-3g acceleration for a solar sail with sufficient sail area.

The distance between each sail and the two stars, as well as the angle of light from each sail relative to the two stars, were calculated in detail by Noah, so that each sail could eventually maintain a balance under the gravitational pull of the star, and the propulsion brought by the light pressure of the star, like a planet, constantly revolve around the star.

This is one of Noah's second major projects for the Water Commission-1 star, and its priority is even higher than that of the faster-than-light fleet.

The name of this project is "Lens Project".

These light sails that surround the entire star system carry no weapons, they do not have any offensive or defensive capabilities, but they are the most important part of the system's defense system. Each light sail carries only one miniature gravitational generator, which is interconnected to form a vast network that covers the entire water system and a star system.

They are the only means that Noah came up with in order to deal with the star-level strategic weapon - light particles.

The gravitational lensing effect is a phenomenon predicted by Einstein's general theory of relativity, in which light rays bend in the vicinity of massive objects due to the distortion of space-time in the vicinity of massive objects (rays propagating along short-range lines in curved space). If there is a massive foreground object in the observer's line of sight to the light source, two images will form on either side of the light source, as if a lens was placed between the observer and the object, a phenomenon known as gravitational lensing.

The gravitational generators on these light sails are designed to amplify this effect, and when all the light sails are in operation, if you observe a star system from a few light years away, the gravitational lensing effect of light distortion will appear, and the positions of the two stars in the water system will be offset by one or two astronomical units in the observer's field of view than the actual position, just like looking at an object through the surface of the water, as long as it is not under the surface of the water (in the star system), the object seen will be offset in its actual position.

When this project was completed, Noah was truly relieved.

In this way, no matter which star system the Kara civilization launches a particle strike on the water committee, their first particle strike will never hit the star, because the position of the star they observed is different from the actual one, and Noah, who has completed the lens project, can modify the "refractive index" of the lens at any time, so that the position of the star that Kara observes every time will not coincide with the actual one, unless they break into the interior of the star system to lock, and the threat of the particle strike can basically be eliminated.

And Noah doesn't think that the Kara civilization will have this kind of costly project in its own star system, except for the defense of light particles, when Noah builds the Dyson sphere and the ring stellar particle accelerator, the level of the stellar system-level strategic weapons, the extra "lens" will become Noah's decisive advantage to end this war.

Although the abnormal scene of the sun's brightness disappearing gives birth to the possibility of the destruction of the solar system, this is only a possibility, not to mention that even if the solar system is really destroyed, the Kara civilization can create a Dyson sphere, and a second one can be created, and the realization of the lens project means that as long as they do not discover that Noah is located in the water committee a star system before the lens project is completed and launch a light particle strike here, the light particles will become no threat to Noah.

After all, no matter how powerful an attack is, you must first hit the enemy.

On the other hand, the search fleet of the Water Commission has arrived 20 light-years away, and the 101 white doves of the Cara fleet and the Sidney-inhabited ship have also sailed 21 light-years away, and they will arrive in the solar system in a little more than 7 Earth years.

The civilization inheritance cabin that was stored by the frigate has arrived in the water committee one star system.

This frigate, which has maintained a maximum speed of 8.5 times the speed of light during the voyage, shuttled between the Water Committee 1 and Kara's abandoned fleet, and when it obtained the "safe" containing the inheritance cabin from the abandoned fleet, it rushed to the Water Committee non-stop.

The frigate has entered the Oort cloud of the Hydro 1 star system, and is currently approaching the five major planetary systems in a conventional propulsion manner in order to prevent the gravitational pull of the galaxy from affecting the curvature of space-time.

On the other hand, Noah, the galaxy's home port, has prepared a separate scientific research spacecraft to analyze this inheritance module.

Something that doesn't know an alien civilization, Noah doesn't dare to put it in the laboratory of the Ark.

Not long after, the frigate arrived in the five major planetary systems, and the scientific research spacecraft greeted it, quickly completed the docking, and handed over the inheritance module.

Noah's phantom appears in the laboratory of the research ship.

The one-cubic-meter "safe" contained creations from unknown civilizations in the universe.

The girl came to the front of the box, put one hand on the box and stroked it, and for a long time, a smile appeared on the corner of the girl's mouth.

"It turns out that this is such an emotion, no wonder human beings like to unpack the express."

The whole body of this box is sealed by a neutron star material shell, and there is no possibility of invasion from the outside under the convention, and the means of opening it are the voice code of the head of Kara, the manual code, and the iris code......

But Noah won't be so troublesome, and the wave-particle cutter has long been hungry.

The fugitive government's information to Noah recorded details of the internal structure of the safe, which made the cutting work quite smooth, and soon the robotic arm removed the legacy pod from the irregularly shaped safe.

In the girl's blue eyes, this wonderful object is reflected.

A regular sphere with a diameter of 0.1 meters, smaller than a football ball and a little larger than a tennis ball, reflects a silvery white light, and there are countless blue light streams on the surface that pulsate slowly.

It is like a pulsating heart, pulsating light and matter at a fixed frequency.

The gravitational acceleration g that is automatically set inside the spacecraft has no effect on it, and it floats in the air as if it has no mass.

In Noah's test, it does have mass, but the amazing thing is that it only has inertial mass, not gravitational mass.

Inertial mass and gravitational mass are theoretical decompositions of the concept of "mass", but this is not to say that these two masses are different, the reason why they are divided into two parts is only derived from the fact that one is derived from Newton's second law and the other is derived from the law of gravitation, but in the end they are all derived from the mass of the object, which is just a "mass" derived from different derivation processes.

With the discovery of gravitons and the application of the Grand Unified Theory, Noah can also erase the existence of the gravitational force of an object, but it is only the mutual cancellation of the artificial gravitational field, and does not erase the existence of gravitational mass in the real sense.

In an object, the inertial mass and gravitational mass are always equal, but this is not a law, just because there has never been a disequal situation, in human physics, there is no way to prove that inertial mass and gravitational mass are not the same quantity, and in Noah's subsequent research, the two quantities have always been used as a unified quantity.

But the existence of this inheritance capsule tells Noah that inertial mass and gravitational mass are not the same quantity, they can not be equal.

The girl held this precious inheritance cabin floating in the air with both hands, and a trace of joy flashed in her eyes.

Just such a conclusion has cleared a lot of fog for Noah's future research in the field of gravity, and sometimes the correct research direction is equivalent to a beacon pointing to the truth.

At the same time, the principle of retaining the inertial mass but zeroing out the gravitational mass is incomprehensible to Noah, and there is no description of this aspect in the tech tree left by the Kara civilization, an unknown civilization that surpasses Noah and Kara in terms of achievements in the field of mass, regardless of the level of civilization.

Noah touched the sphere full of inexplicable technological art suspended in front of him with his finger, and the illusory light and shadow overlapped with the blue pulsation, but nothing happened.

A hint of frustration flashed in the girl's eyes, in the records of the Kara civilization, the opportunity for them to open the first inheritance cabin was when one of their clansmen accidentally touched the surface of the inheritance cabin, so they deduced that the physical contact of intelligent life could be the key to open the inheritance cabin.

And this inheritance cabin does not seem to treat artificial intelligence as life.

It's kind of sad.

But for the current Noah, whether an alien creature acknowledges himself or not is not so important.

Noah gave the order, and the leader of Sidnia, Karen, was heading towards the ship, and the legacy module was put back on the analysis bench by the robotic arm.

"Even if you don't admit it, I'm still a life, and I'm certainly higher than your creator, because I'm a civilization in itself."

An ethereal voice echoed through the laboratory, and Noah looked indifferently at the quietly floating inheritance chamber on the analysis table, without a trace of waves in his tone.

In Noah's somewhat strange expectation, the Legacy Module did not respond, or it did not have the function of responding at all.

Even as a machine, it was a failed existence in front of Noah, and a trace of disappointment flashed in the girl's eyes.

And the next second when the girl turned around, something that could subvert the common sense of physics of Noah from his birth to the present and for a long time in the future happened in the water committee a star system.

At this moment, and for quite some time to come, every star, every life, every particle of dust, every atom, and even every electron cloud in the water system was frozen in the Planck time that the girl turned around.

It's a cold world, with no thermal radiation and no molecular thermal motion, a world of absolute zero.

This is a dark world, without the transmission of light wave and particle duality, a dark and lonely world.

This is a dead world, a world that is completely static and lifeless compared to the outer universe.

This is a separate cosmic frame.

A world where true entropy does not change, and time stands still. (To be continued.) )
