Half-immortal civilization

Chapter 740 The War of Theory

Three hours passed in a blink of an eye, with tears, blessings, and concerns; but in the end, everything turned into a firm determination to fight.Not for anything else, just to protect this warm and civilized land!

In space, electric sparks flicker and magnetic motors work violently.The powerful thrust means that the 150-kilometer-long spacecraft does not need to be driven by complicated light pressure at all; the breakthrough in the research and development of the magnetic engine makes the kinetic energy of the spacecraft more sufficient and more flexible.

In just one month, the spacecraft has accelerated to 0.3 times the speed of light, and got rid of the relatively (solar system) Vulcan galaxy, which is much weaker, and entered space; it has since disappeared from the field of vision of the telescope.

In the lonely space, the four human spaceships are constantly accelerating.Do not allow the enemy to invade the house and fight.In the battle in the universe, when the enemy hits the door, it will be too late!Human beings have experienced some battles, and have deduced too many possible battles.The best way is to keep the enemy out of the country!

There are only soldiers in the spaceship!Everyone looked serious, even while the spaceship was advancing, they were still immersed in the virtual network, constantly increasing their combat experience.Battles in the universe are very strict tests of individual abilities.The distance of hundreds of thousands, millions, or even hundreds of millions of kilometers far exceeds the second propagation distance of the speed of light. Under such circumstances, if you want to hit the opponent, you can only rely on experience and judgment.Computers also cannot provide accurate information.At this time, when the technology is not much different, it is more a test of the combat quality and wisdom of the soldiers!

Behind four huge spaceships.Follow more than 2000 huge war flying saucers.Compared with spaceships, flying saucers have the advantage of arrogance that there are no dead ends, every place.All weapons of war can be arranged.Also, the surface of the flying saucer is densely packed with fighter jets.

Standing in the space command center, the gray-haired Du He managed to break through the golden core stage to continue his life at the last moment of his life, and Du He could only keep his old face.However, this cannot conceal the capabilities of an outstanding military talent.Mo Wentian personally led the fleet to set off, while Du He stayed in space.Responsible for directing battles and coordinating.

"Commander, the spaceship formation has left the galaxy. Now the speed has reached 0.6 times the speed of light."

"En." Du He responded, but the scientist next to him was calculating.

In fact, there is another reason for taking the initiative to attack, and that is to use the theory of relativity to block the enemy!Using relativity?It sounds ridiculous at first.Just a small theory, this thing can also be used as a weapon?

But in fact, that's it!The enemy is now 3 light-years away from human beings. Calculated according to the speed of the enemy’s spaceship at 0.8 times the speed of light, if we do nothing, the enemy will definitely arrive at Zhurong Star in four years (counting the deceleration time).But what if humans take the initiative?The enemy's spaceship travels at 0.8 times the speed of light, the human spaceship travels at 0.6 times the speed of light - and will eventually accelerate to 0.7 times the speed of light.So here's the problem, anyway, in the universe.The speed of light is constant.Even if the two objects seem to be moving in pairs now, the absolute speed between them should be 1.5 times the speed of light?

wrong!impossible!

Assuming that the distance between the two spaceship teams is three light years, then one side moves at 0.8 times the speed of light.The other party moves at 0.7 times the speed of light. Under low-speed physical conditions, it should take two years to meet.However, in the high-speed physical state, the time when the two actually meet is: 2.822 years!

It's a strange phenomenon, but it's true!Assume that the coordinate of Zhu Rong is "0", and now the coordinate of the enemy spaceship is "150".Well, in theory, 4 years later.The enemy spaceship should reach point "0"!But now, due to the departure of human spaceships, the space-time between the two is distorted. After 2.822 years, the enemy's spaceships can only reach the position of "70".Then, even if the human fleet is killed immediately and continues to move forward, it will still take 1.75 years to reach the goal! (Calculation headache. Hiss...) Originally, the distance of 3 light years, 0.8 times the speed of light, the enemy needs 3.75 years; but now it takes (2.822+1.75=4.572) years, adding 0.822 years of love out of thin air!

This is one of those practical examples of scientific theory!Taking the initiative to attack, in addition to defending the enemy at the gate of the country, it also won at least 0.8 years for mankind out of thin air!And 0.8 years is enough for human beings to cultivate a group of troops with initial combat capabilities!

And the most important thing is that this kind of change cannot be noticed by people and machines in the coordinate system!That is to say, the time has obviously increased, but the human army and enemies in a state of war cannot notice the change, because this is the change of the universe itself!At this time, only "bystanders can see"!If the other party doesn't know this, they may be bullied by human beings—but come to think of it, even if such a developed civilization does not have a top theory like the theory of relativity, it must have experienced star battles, and such a phenomenon will never be ignored.Strategically, human beings will never ignore this aggressive civilization!

"Dididi..." In Zhu Rongxing's space base, scientists are calculating.The complex space environment makes it extremely difficult for the star cannon to aim.Especially now that the relative movement of human spaceships and enemy spaceships has added countless changes to the already complex universe.And that's not all, the speed of the rail gun also has a huge initial speed, relative to the enemy's spaceship, it is a relative movement with huge variables!

In addition, there are also the movement of the universe itself, etc., which are very complicated calculations.Now, the supercomputer has been working for more than a month, and the calculation progress has just entered 90%!

There is a saying that a person who travels a hundred miles is half ninety, and it is the same in the field of science. When entering 90%, the progress bar begins to slow down.

In space, the star cannon is still accelerating slowly, even surpassing the gravitational field of the planet, and the speed has reached 30 kilometers per second.The battle in the starry sky is different from the ground, in order to adapt to the huge reaction force.Had to accelerate the Star Cannon in advance.After waiting for the cannon to fire, the huge reaction force will stop the cannon instantly.and.Such an early acceleration effect will also improve the utilization rate of energy as much as possible.This small change can increase the energy of the projectile by 1%!

Don't underestimate 1% of energy, you must know that accelerating a projectile to 0.8 times the speed of light consumes enough energy to meet the power consumption of a city with a population of tens of millions for ten years!One percent of the energy is the total electricity for a month!

Intense war preparations have begun in every corner of human society.Not only the starry sky cannons of the Zhurong galaxy are ready, but also the starry sky cannons of every planet.Star Cannon.Although bulky, it is the last and strongest line of defense for human beings.Star Cannon.A weapon that maximizes physical impact!In extreme cases, one launch can be made every hour.

With a length of tens of thousands of kilometers, the star cannon is definitely the Great Wall of technology!

A silent universe, a silent battle.war.At a distance of three light-years between the two parties, and at a time span of three years in advance, it has already started.This is a war in the universe, a completely different way of fighting on the ground.

"Beep!" At Zhu Rongxing's starry sky base, the computer finally calculated the trajectory of the enemy's spaceship after two months of non-stop calculations!At a distance of about 3 light years, about 28 trillion kilometers, it has been locked!

"Wait, don't launch yet!" Du He stopped the scientist who was about to press the start switch happily.

"Why?" The scientists were puzzled.

"This is a strategy." With the self-confidence of a soldier, Du He must of course explain clearly to these scientists that intellectuals are sometimes very stubborn;Scientists can continue to complete scientific research and progress.

"That's it." Seeing that the faces of the scientists were about to change, Du He quickly explained, "We have to calculate. It is best to let the spaceships of both sides approach the combat distance, so that our shells can hit the enemy. If it is too early, the enemy will be killed." Be alert, unknown changes may occur. Space is too far away, we only have one chance to attack!

After an attack, regardless of whether it hits the target or not.The enemy may change the movement state, which makes us lose the direction of locking; it is also not conducive to the army that has already set off to lock the enemy. "

"Oh..." The scientist touched his nose resentfully.Then restart the calculation.Calculate the distance at which two fleets of spaceships enter a state of war.According to the plan, humans will start the battle with rail guns at a distance of one light-year.And here is another problem. After the rail gun is fired, the speed is faster, and if the enemy counterattacks, the speed must be very fast, and the powerful civilization is probably a light-speed weapon.

Then this will cause all the previously calculated data to be invalid and need to be calculated from scratch!

"Alright, alright..." Scientists are not lacking in patience. Although the calculation of time and space is very complicated, especially every moment and every position is changing, humans can still calculate the precise space-time position.Standing on the planet, it is already possible to calculate a one-meter-sized target three light-years away.

However, such advanced technology requires a technical team of thousands of people!The Star Cannon is currently the only human weapon that cannot be completely controlled by soldiers.Without him, the technical content is too high!It even requires a professional technical team to develop and temporarily calculate!

In other words, the Star Cannon is not only a weapon, but also a pinnacle product of technology and one of the sharp weapons for scientists to explore time and space!This is not only a weapon, but also a peak experimental machine!

When the Zhurong galaxy was completely in a state of super war, the entire human world, hundreds of spaceships set off, and as long as the galaxy was within 20 light-years from here, they all began to send troops.Farther away, it's too late; but farther away sends armies around the Earth - the solar system is the heart of humanity.

Whether and how powerful the civilizations that came to invade are strong, human beings have not yet counted.But, be careful sailing the boat of ten thousand years, and this is a battle of human life and death.If the enemy is not strong, at worst, it will be regarded as a super-large-scale military exercise; but what if the enemy is really strong?

The lonely space is ignited by human enthusiasm!Human spaceships come from various galaxies, with different shapes and sizes, but they carry the same enthusiasm! ——Destroy the enemy!
