Su Meng's spaceship is still relying on inertia to sail, with Su Meng's current mastery of alloy material technology, the spaceship she is making now is already the largest spaceship that the material strength can bear, if it is several times larger, then the spaceship will produce obvious structural deformation under its own gravity, if it continues to accelerate, the main structure of the spacecraft will be damaged, which is why Su Meng did not continue to make a large planet-sized spaceship, not because he didn't want to build it, but because he couldn't build it.

Su Meng even had an idea, could he continue to optimize the layout of the ion thruster or the structure of the spaceship, so as to increase the maximum speed that the spacecraft could withstand.

The spacecraft accelerates to 30% of the speed of light, continues to accelerate, and must provide stronger thrust to continue to accelerate, this thrust is currently close to the upper limit of the spaceship's bearing, if you want to continue to accelerate, it is necessary to increase the power of the spaceship's thrusters, and then it will increase the force of the spacecraft, making the probability of the spaceship collapsing more than 50%, which is an unbearable risk, so Su Meng's spaceship, at present, can only move at 30% of the speed of light.

Some people think that as long as the thrust is constant, it can accelerate infinitely, this theory is absolutely wrong, and if this theory is correct, then there is no upper limit to the speed of light.

In fact, when the velocity of an object increases, the kinetic energy contained in it does not increase in a proportional way, but in an exponential way, and the closer it is to the speed of light, the more obvious the trend of exponential increase in kinetic energy, which means that more energy is needed to accelerate the same speed.

When the speed of the spacecraft increases to close to 30% of the speed of light, the ship's ion engine begins to run overloaded, fortunately, this overload can be withheld, but once the speed of light exceeds 30%, the load of the spacecraft's ion engine will also exceed the maximum withstand limit and explode.

Sometimes a theory will encounter logical errors, and then the theory must be wrong, for example, the theory that the speed of light cannot be exceeded and the theory of the constant speed of light are contradictory, this theory holds that if a light ray is illuminated by a flashlight on a spaceship traveling at the speed of light, the observer who is a little stationary outside the spacecraft will see that the speed of the light is always the speed of light, regardless of the direction in which the light is sung. This is incomprehensible in logic and violates the most basic mathematical principle that 1+1 is equal to 2 and 1-1 is equal to 0, i.e., the theory that the speed of light adds up to twice the speed of light and subtracts the speed of light to zero. The solution to this problem is to look at light as a wave that propagates in space.

This conclusion is also the reason why Su Meng finally thinks that he has no way to create a spaceship beyond the speed of light, because if the nature of space does not change, Su Meng will never be able to create a spaceship that exceeds the speed of light, and if the nature of space changes, a new speed of light limit appears, and it is still impossible to exceed the speed of light.

However, Su Meng also saw a glimmer of hope from this restriction.

She can change some of the rules of time around her, but for the study of the rules of space, she can't touch the source, so she can't change the essence of space, and her awakened ability to control the material origin can only change part of the origin of matter.

Su Meng made some assumptions, if she was the master of the spatial origin, then the speed of light would be as simple as eating.

By controlling the origin of space, Su Meng can set new spatial rules within her super-sensing range, that is, to set the speed of pure energy in the new space, then she can do things that exceed the speed of light in the space outside the range within her super-sensing range, that is, super-light speed in a certain sense.

It's a pity that she doesn't control the spatial origin, and her control of the material origin only exists on the surface, rather than going deep into the origin.

What makes Su Meng even more helpless is that her control does not come from a breakthrough in science and technology, but a gift from the fusion of alien super civilization products.

Su Meng didn't know how to study the origin of her body at all, although she knew that the path to promotion was there, but at present, she could only think about it, and she couldn't spy on it at all.

However, Su Meng has more ideas about the length of her sister's life, and the previous creation of repair light is some application of pure energy.

The human body repair machine was actually just a giant gamma ray transmitter, and then Su Meng changed the material rules there, so that this gamma ray was transformed into repair energy.

The origin of everything is Su Meng.

Su Meng hugged her sister and did not go to the experimental area, but came to the main control hall.

The big screen flashed with data updated thirty times per second, this kind of page turning speed is simply impossible for ordinary people, but Su Meng watched it very easily, she has evolved to the fifth stage not only to master the rules of material origin, but also to greatly enhance her body, her super sensing ability is thousands of times stronger than her sister.

What is displayed on the screen is the detection data of the surrounding starry sky, and the distance that can be detected at the farthest of one light minute is also Su Meng's current limit, if the spacecraft is far away, it can't be received, after all, the error is unavoidable, on the high-speed spacecraft, the radar signal emission is removed, and it can't be recovered at all.

In addition, those optical telescopes and ray telescopes were aimed at the target of Su Meng's voyage, the star 17 light-years away.

The distance is too far to discover the trajectory of the planet, and the study of the orbit of the star cannot be carried out, after all, it is not a temporary thing, the orbit of the star is too long, and without decades of continuous observation, nothing can be found at all.

And after waiting for decades, Su Meng has already arrived there.

At a distance of 17 light years, the star in Su Meng's optical telescope is just a small fireball that only occupies more than 40 pixels, the color of the star is yellow, as young as the sun, and the ratio of red giants to ordinary stars in the Milky Way is about 1:3, this ratio shows that the Milky Way is not as old as it seems, and even quite young.

You must know that this universe has been born for more than 10 billion years, and old stars have long since died, after all, even a stable star like the sun can only exist for about 6 billion years before turning into a red giant, and when its life reaches the age of 10 billion years, it will officially enter destruction.

This universe is still very young, and Su Meng is thinking about her next plan while looking at the vast amount of pictures and data collected by the optical telescope.

In another 55 years, Su Meng will reach that star, Su Meng has stored enough material to continue to store substance, and she is ready to carry out a giant material test there to see if she can make a better material than the alloy she has mastered so far.

Although the computing power in Su Meng's mind is extremely strong, it is limited after all, and the huge experiment cannot be replaced by pure simulation, after all, in the real world, there are many things that Su Meng does not know, and without that part of the unknown, Su Meng's simulation can only be accurate in a small range, and it is okay to analyze some things, but to innovate, it is still necessary to rely on huge experiments to do it.
