Chapter 117: Different than I Imagined

As the main gun fired, dozens of laser weapons located at the bottom and side of the Callisto ship also roared. A thick beam of light plus dozens of small beams tore through the darkness and roared towards the silver mist three million kilometers away.

"Positron cannon cooling countdown 30 seconds, prepare for the next round of shooting."

The magnetic confinement coil and other components of the positron cannon are made of superconducting materials, and there is no resistance heating problem, but the various gold and platinum sheets that generate positrons and the various facilities that separate positive and negative electrons cannot be completely superconducting, so after the main gun of the Callisto ship fired a shot, there is still a certain cooling time.

Laser weapons are high-energy photon beams.

Obviously, the speed of laser weapons is the speed of light. As long as there is no superluminal detection technology, it will be hit as soon as it is seen.

The positron cannon is a positron beam. Because electrons have mass, their speed is slightly lower than the speed of light, but on a scale of three million kilometers, this difference can be completely ignored.

So although the silver mist is a third-level civilization creation, it is impossible for it to detect the attack of such weapons in advance. In fact, not only Silver Mist, but even humans only know "I fired", as for whether it hits or not, it will take 20 seconds to see.

From the perspective of a bystander, the real laser weapon is actually invisible, and you can't see the radiant light beam like in the movie.

If there is such a God's perspective, you can probably only see the laser state of laser weapons and positron cannons before firing, and after such cannons are fired, you won't see a bright light beam like lightning.

Of course, after the laser weapon is fired, due to the existence of some gas dust in the universe, some of the photons in the emitted light beam will hit the gas dust composed of hydrogen, and then these photons will be diffusely reflected, so the bystander can still distinguish the direction of the laser beam from the rare diffusely reflected photons.

Simply put, you will see a blurred and hazy light beam.

The positron cannon is another matter. Because it emits positrons, it is impossible for the human eye to see the real light beam. Not only the human eye, but also the detection instrument cannot see it directly.

The reason is that the human eye "sees" the result of sensing photons, and although various detectors can detect electromagnetic waves of various bands, positrons are obviously not directly observable by detectors.

Therefore, if the positron cannon is fired in a vacuum without gas and dust, even the emitter will probably not be able to see anything.

However, true vacuum environments are rare in the universe. Although most of the universe is called a vacuum, there are still some rare hydrogen elements diffused there.

The observation of the positron cannon beam also relies on these gas dusts. A small number of positrons react with the electrons in the process of encountering these gas dusts, and then emit some photons. The detector detects the flight trajectory of the positron cannon based on these randomly flying photons.

Therefore, in fact, now, including Yue Yuan, all the people in the bridge of the Hope who are looking at the big screen actually see only a dim light flashing by.

Unless it is rendered by computer, the laser weapon shooting seen on the big screen is like this.

Because of this, laser weapons and positron cannons will be attenuated to a certain extent before hitting the target. This is the process loss of the environment and cannot be avoided.

If it is in the atmosphere, the loss is even greater.

From this point of view, the positron cannon is not suitable for use in the atmosphere, because the electrons in the molecules in the air are the first targets that the positron cannon contacts. Before hitting the real target, all the electrons in the air along the way must be neutralized.

Well, but speaking of it, as long as the power is large enough, it is also possible. In addition, when using the positron cannon in the atmosphere, you will really see a bright light speed shooting at the target.

In fact, no one in the bridge of the Hope was surprised to see this completely different picture from the usual imagination, because they all have common sense of physics.

So after the main gun fired, Yue Yuan and the scientific officer and others were all concerned about the timer on the screen that started counting from the firing.

5 seconds, 9 seconds, 10 seconds,

11 seconds, 13 seconds, 14 seconds, 16 seconds, 18 seconds, 19 seconds.

The timer just jumped to 20 seconds, and the picture that had been refreshing on the screen changed in an instant, and a light suddenly appeared on the quiet screen.

It looks like a flashlight shining into the thick fog, but there are some differences. There are many dense flashes where the beam of light touches the target.

The reason is that the positrons touch the target and annihilate with the target electrons, which triggers a series of explosion reactions.

Of course, in space, this type of explosion cannot be an explosion in the traditional sense, because its mechanism is that the high-energy photons produced by the annihilation of positrons and electrons destroy the structure of the target.

So, less than a second later, people saw the silver fog with a big hole on the right side under the radiating light.

This is what the optical telescope of the Hope saw.

In another split screen, because of the different types of detectors, the displayed content is different. Some only show a quadrant wave, while others show many spots of light.

After seeing these pictures, the fire control operator, signal expert, communicator and other staff on the Hope immediately used computers to summarize and analyze the information on the pictures.

Based on these feedback information, they need to determine whether the target is hit or not, the next offset direction of the target, the time difference and other factors, and then quickly adjust the direction of the Hope to aim the main gun of the Ganymede ship at the possible deviation position of the next target.

"The positron cannon hit the target and penetrated the target! The visual damage is 5% of the total target volume. It is impossible to determine the core and whether it has caused fatal damage to it."

"Blue laser weapon No. 14 missed the target!"

"Blue laser weapon No. 6 missed the target!"

"Blue laser weapon No. 8 missed the target!"

".Missed the target"

"Blue laser weapon No. 7 hit the target, the hit time was 1.78 seconds, and no obvious damage was caused."

After a bunch of misses, another hit information finally appeared in the fire control combat system, but the result was that the opponent was unscathed.

Laser weapons are different from other types of weapons. After hitting the target, the hit time needs to accumulate to a certain extent before it will cause high-temperature burning damage to the target.

It is not like in the movie, where a laser shot will cause a huge explosion.

This is determined by the principle of laser weapons.

Of course, it is also related to the power of laser weapons. If the technology is powerful enough and the laser weapons are high-energy gamma rays, the damage will definitely be much greater, and it will be no problem to melt the target as soon as it hits it.

However, humans have just entered the first-level civilization, and the scientific research power has been concentrated on positron cannons, and high-energy gamma ray laser weapons have not been developed in time.
