Before there is a more in-depth breakthrough in the theory, the speed of light is one of the basic constants, and deeper matters will not be discussed for the time being.
Accelerating a massive object to close to the speed of light consumes a lot of energy, and on a cosmic scale, light is still too slow. After all, light-year is the unit of distance.
Then there is nothing we can do if civilization is taken away?
This paper on the universe will also provide some hints and ideas when it comes to problems for civilization, such as quasars showing a huge red shift in the spectrum, and the space expansion of the Big Bang.
This all tells civilization a truth: the speed of space expansion can exceed the speed of light. This is the basic principle of the curvature engine.
Use huge energy to distort space, causing direct differences in space, allowing space to pull objects forward.
In layman's terms, just like cutting off a straight river to create a waterfall, gravity will pull the object traveling on it to fall rapidly.
The curvature engine essentially makes use of the laws of the universe, and it also does not exceed the speed of light. Because light is still at that speed in the curvature bubble, but the outer space is moving at super-light speed.
Only civilizations that master the curvature engine can have the ability to travel across the galaxy. This technical theory may seem simple, but only the top civilizations can do it.
Ordinary civilizations can only use hyperspace engines, and the existence of hyperspace can be regarded as the greatest kindness left to civilization by the universe. (In Warhammer 40k, there is subspace.)
In the memory of Swarm that Zhang Han saw, Swarm's curvature engine battleships were very huge, even larger than Swarm's Leviathan, because warping space inherently requires large mass and high energy.
Sometimes in the inter-galactic Swarm fleet that is about to set off, the mass of the warp engine battleship can reach half of the total mass of the fleet. (Here is a reference to the Tyranid Zerg jump ship.)
The small curvature engine in Zhang Han's body is indeed a huge advancement in technology, and is one of the most precious gifts left to him by the previous Hive Mind.
Stretching out his right hand like an iron arm, Zhang Han shook his head at the Perseverance in the distance. The curvature engine ran at normal power, and the surrounding space began to distort.
To Zhang Han, this process was like a moving picture in a movie. One minute later, he arrived at a place one million kilometers away from Perseverance.
This is an extremely close distance. The pull of the strong gravity and the extremely high temperature make Zhang Han feel a little stressed, but these still do not threaten him.
Observing the terrifying cosmic creation like stars at close range, Zhang Han felt that his cognition and soul had been sublimated. Compared with stars, its size was not even an ant. This terrifying sense of oppression could make ordinary people unable to breathe.
But the life form of Zhang Han is no longer the little otaku on earth. His mental power and physical body are far beyond ordinary life forms. The pressure of giant objects exists for him, but it will not really make him feel scared or frightened.
Suddenly there was violent movement on the surface of the star, and a million-kilometer-long prominence erupted from the sun and ejected along an arc-shaped path.
Coincidentally, Zhang Han was on this path. After thinking about it, Zhang Han reinforced his shell with Psionics and mobilized the body's protective system. He planned to test the limits of this body.
The huge prominence Consume, which was as huge as a fire dragon, dropped the Zhang Han that was more than thirty meters high. It was easier than a whale swallowing a bacterium. In the blink of an eye, the Zhang Han disappeared into the red material.
This time the ejection of the prominence is large in scale and lasts for a long time, and the entire star seems to have grown a small ear.
Ten minutes later, the red Zhang Han rushed out of the prominence, bringing with it a large amount of material. This behavior seemed even more exaggerated than a person rushing out of magma.
Zhang Han was also stunned by the strength of his body. He looked at his arms and felt his body. If he didn't feel anything at all, that was not the case. If he felt anything, it would be like taking a hot bath.
"What level of material knowledge is this..." The new body gave Zhang Han so many surprises that he didn't even know how to express his amazement.
He doesn't plan to test his power anymore. He needs real test data, data from the combined research in the Cerebrate and Hatchery laboratories.
Ether dragon? I can tear it apart with my hands now. Although Zhang Han is still a little petite compared to the Leviathan beasts, in terms of strength, it is only stronger than weak.
Just as he was about to fly back, Zhang Han discovered the test records left by the previous Hive Mind.
The first line reads heavily:
Overmind's consciousness was shattered by enemy weapons, and losing Overmind was unacceptable to Swarm. Those Swarm and Hatchery who lost control initiated emergency plans, and they hatched new logical Zerg units to replace Overmind.
I don't approve of this approach. I will collect discrete fragments of consciousness to reshape Overmind. Swarm needs Overmind... I need Overmind.
What follows is the complex test process of Hive Mind. It will also fight Stellaris Council and other Swarm. But its purpose is not to Consume Galaxy, nor to become a new Overmind. It is only to collect energy and rare elements in order to rebirth Overmind.
Zhang Han cannot understand the experimental process and complex theories. His current Hatchery database is missing, and many technologies have not been decoded.
Moreover, there may be a lot of theories and technologies developed by Hive Mind himself under the orders of Cerebrate, which are not stored in the universal gene chain.
While collecting fragments of Overmind's consciousness, Hive Mind is also building a new body for Overmind. The passing of Overmind has caused Swarm to face the biggest crisis, so we must avoid the same thing happening in the future.
The new body must meet various needs. Even if only Overmind is left from Swarm, Overmind can survive on the new body and lead Swarm to make a comeback.
In order to make Overmind's body meet such high standard design requirements, Hive Mind asked a large number of Cerebrate to do scientific research and theoretical verification almost every day, and finally it invented a new material.
Everyone knows the wonderful uses of nanorobots. From repairing cells in medicine to destroying enemies in military, nanoscale robots can turn decay into magic. I believe the name Gray Feng is familiar to many people.
Since nanorobots can repair cells, why not turn cells into nanorobots? Nanorobots have both biological and mechanical properties.
This is not whimsical, it can be done. Swarm's technological accumulation has long passed the threshold for manufacturing cellular nanorobots. In terms of life and genes, Swarm is second, and no one dares to say first.
It's just that Swarm rarely does this because the price/performance ratio is low. How expensive is it to use cell nanorobots to build a Swarm that can cover the sky and the sun?
To crush the enemy, sometimes it is enough to hatch more low-level Swarm units. With the help of auxiliary facilities such as Swarm Network, Creep, the lethality of low-level Swarm units is equally strong.
For example, Zergling and Needle Crawler, who are clearly cannon fodder, can still fight against thousands of Warcraft even when their physical strength, strength, or Psionics are not dominant.
