Less than three hours passed in a flash, and the starry sky outside became fantastic and blurry because of the relative superluminal warp speed, relying on the powerful information processing ability of the night thorn, Su Zhao was even able to find some starlight beating, because of some dark matter or gravitational lensing effect caused by the twists and turns of the light path, with his own observation as the fulcrum of the rapid change and out of the lens observation range, suddenly returned to normal all kinds of wonderful scenes.

The countdown is complete, and the Nebula-class battleship is out of warp and connected to the Nebula's observation system.

In the extreme distance in the direction of progress, a huge red giant star is emitting a dark red light.

Apparently, this is a stellar object that has reached the end of its life cycle.

However, according to the ZR01 provided by Kunlun, the relevant parameters of this red giant star, its real lifespan, is only 3.7 billion years.

3.7 billion years, for ZR01, which was originally a yellow giant, is just the prime of life, and there are still billions of years before it collapses into a red giant.

Today, however, it is a real dark red glow, indicating that the average surface temperature is only in the low temperature range of 2000 K to 3500 K for the surface of a star.

This shows that this star, which was supposed to be blazing and releasing infinite light and heat, has suffered an unexpected change, so that the main sequence star, which is the most important source of energy for the galaxy, has entered a low-energy state in advance, which is a devastating blow to the civilization on which the entire galaxy depends.

The data shows that planets No. 2 to No. 4 were directly destroyed in the accident of the main sequence stars of that year, the orbit was changed, and the stars were broken.

After this system number 09, there are actually other planetary records, except that only a large belt of rubble remains.

Quite simply, as a highly developed civilization home galaxy, as long as the environmental conditions in the galaxy are within the permitted range, it will naturally be vigorously developed.

The planets after 09 were originally used as the object of resource development, but after the civilization went farther and farther, they were transformed accordingly as a powerful military base and as the backbone of the arch defense of the home galaxy.

Only after the vast majority of the system's defenses have been dismantled can any hostile presence ascend to the home planet of this civilization, a place that no civilization will tolerate desecration.

But, obviously, the ZR civilization has not been able to hold their home galaxy.

All the outer military planets were shattered, and all the orbital facilities of Planet 09 were destroyed, forming countless orbital space garbage, and the entire Planet 09 can be clearly seen to be wrapped in space junk in the distant view of the planet.

The Kunlun fleet entered from the vertical plane of the stellar system's orbit, and with the help of the gravitational slingshot effect of ZR01, it accurately passed through the channel to the Lagrange orbit region of 09.

Su Zhao looked at the real-time galaxy celestial body movement map at the moment, and found that Kunlun's high technology was actually reflected in the details.

Interstellar navigation is, in a way, quite simple, the vastness of space, as long as the starship flies according to its destination.

However, actual space travel is a very computationally intensive thing.

Deep space environment

The tube is quite empty, but gravity, one of the fundamental forces, controls the direction of the sailing unit.

The starship needs to have a superb gravitational detection system, and realize the corresponding attitude correction function according to the detection data, and then dynamically correct the course in real time.

The problem brought by the long astronomical distance of interstellar voyage is that a little deviation in the route, multiplied by tens or hundreds of light years of travel, is a huge and extreme error.

The Federation seems to be able to carry out free galactic voyages, but in fact, all voyages have extremely fixed routes, and the ship's main engine has accurate and accurate course data that is updated in real time.

Moreover, the passage between the Federation star fields is even narrower than a single-plank bridge on an astronomical scale, and it is a channel with a fairly small margin for error.

In light years, once the interstellar channel is out of the warp state, the regular sailing speed of any starship is as slow as a snail, and, except for the ability of large starships to quickly self-correct the warp course near the civilized star sector, the average starship main engine does not have enough detection capabilities to self-correct in a short period of time after the course is deviated too much.

Of course, in the galaxy, this is because the star map of the civilization region of the Federation Galaxy has been perfected for many years, and there are generally few deep space navigation deviation accidents, and the perfect star map data allows the Federation starship to reach the nearby civilization circle according to the star map as long as it is not lost outside the extremely remote channel.

However, the danger of deviating from the course is still high, which is why the starship main engine is extremely computationally stable.

If it is in an unfamiliar galaxy with no relevant data, then deep space navigation is basically a death for the Federation starship.

Su Zhao couldn't help but hypothesize what would have been the result of Sirius if it hadn't been directly out of warp near the Hope Galaxy, but in the deep space region.

If Sirius is in deep space and wants to reach the vicinity of any of the massive stars, then it will first need to collect data on the trajectory of the object.

This is because all the data that can be detected in real time is false, with a variety of factors such as time shift, star shift, space shift, dark matter torsion, etc.

In the former, the light emitted by the stars is not affected by gravity, but the space in which the light travels has a mass-distorting effect.

In other words, the light of the star, when it departs from the galaxy, is distorted by the mass of the galaxy in the forward space, which reverses the direction of transmission to a certain extent.

Not to mention the impact of massive celestial bodies, such as representative black holes, supernovae and other star pull-up lenses on the way to deep space, the strong gravitational pull distorts the space near these celestial bodies, causing the light to continue in a distorted path.

This is the shift in the path of the light of the celestial body, and secondly, there is the astral shift.

The infinite stars in the universe are all in dynamic motion, and this forward speed, in some areas, can reach the speed of light relative to the extra-river reference, and the essence is the same as the spatial warp effect, of course, in the river system, this characteristic exists, but it is not obvious.

However, the offset speed is still an extremely high macro speed, which is another difficulty in determining the new route.

Finally, the space where the starship itself is located is also in a dynamic shift, the first factor is the expansion of the universe itself, and the second point is because of the movement of celestial bodies.

To put it simply, a starship in a state of trek, first of all, will not say that it will continue to sail, it must stop fuel consumption first, at this time, with its own muzzle velocity, the influence of space offset, the starship actually can't even determine its own coordinates at all.

Secondly, the observed astral light needs to be carefully analyzed and the interference factors affected by it can be discharged by technical means in order to obtain the original approximate position of a path star.

The deviation from its true position can be described by a simple calculation, such as substituting the Hubble constant into the spectral data to measure a star 5 light-years away, then the light received by the object is emitted by the star object 5 years ago.

After completing the optical path correction, it is the time offset of these 5 years.

The data observation and analysis of the first two requires continuous time to establish long-term observation data in order to obtain accurate information on the operation of celestial bodies from the huge data.

Finally, there is its own spatial offset parameter, which is actually not large compared to the first two, and the amount of data is not high, but it is a point that must be considered.

It is still the first reason for deep space voyages, a little mistake in the route, will be magnified, and the establishment of its own coordinate system is indispensable.

As a result, if Sirius were lost in deep space, there would be no doubt that the Federation starships, which could be said to know nothing about the Andromeda Galaxy, would face a complete Star Trek.

All Isis can do is determine the position of the nearest mass object as soon as possible, and must not lose the ability to travel at warp speed, otherwise the maximum normal speed of the starship would be close to two years of sailing time, defined by the shortest standard celestial light distance in deep space.

"Isis, when you left the warp state and arrived in the Hope Galaxy, the warp function of the starship itself seemed to have been damaged, right?"

"Yes, Su Zhao, at that time, the warp engine had been overloaded and damaged due to the high warp alignment work, and the ship lost the ability to carry out warp sailing."

"Really? We're in luck. ”

Without the ability to sail at warp speed, lost in deep space, unfamiliar galaxies, and no star map, Su Zhao is now very glad that he is still alive, and even pilots a super strong night thorn armor from Kunlun.

Then, all of the above shows that deep space navigation requires extremely advanced deep space exploration technology, which is inconceivable for Kunlun's advanced technical level.

First of all, after Kunlun was activated, in just a few dozen hours, it completed the correction of the star offset for millions of years, and updated the original star map.

Secondly, it can directly carry out a deep space voyage across light years so quickly, not to mention the extremely high warp speed level, and can locate the target celestial body so accurately, Kunlun's star map program accuracy is quite high.

Finally, in the face of such a complex internal environment of the ZR galaxy, the orbit was accurately calculated to reach the Lagrange equilibrium region, which all of the above aspects illustrate Kunlun's huge and superb technical accumulation in interstellar navigation.

Su Zhao suddenly felt that the distance of 2.5 million light years did not seem so far away, perhaps......

"One day, I have a chance to return to the galaxy?"
