Su Meng has also been experimenting with various materials on the spacecraft, of course, due to space constraints, the scale of the experiment is relatively small.

After Su Meng stayed in the main control room for seven or eight days, she took her sister to the experimental area.

In the experimental area, Su Meng began to experiment with a new material.

Originally perfected by Su Meng's enormous computational power, this material is a super-complex extremely heavy atom-class material.

This material is composed of elements with proton number 128 and elements with proton number 231, these two elements do not exist in the universe, but Su Meng can directly produce them through energy production in the simulation in his mind, and at this moment, it is the time to verify whether the simulation in his mind can succeed in reality.

Su Meng came to a laboratory table, on the experimental table, there is a crystal vacuum ball, under the action of the magnetic field, this crystal vacuum ball is suspended on the experimental table, the crystal ball is an absolute vacuum, Su Meng is ready to make this substance in it, in order to prevent some accidents.

Su Meng closed his eyes and created an element that did not exist in the universe, and the energy consumed seemed to be different from ordinary creations, and tens of thousands of standard energy were consumed in an instant, and then in the vacuum ball, a mass of black light was created.

Su Meng opened her eyes and looked at the mass of materials with curiosity in her eyes.

This mass of material is an alloy made by mixing one element with proton number 128 and neutron number 128 and another element with proton number 231 and neutron number 233 in special proportions, and its total weight is about 1g.

At this time, the radiation monitor placed next to it sounded an alarm, and Su Meng took a look at it, showing that the radiation intensity exceeded the standard intensity by 2,000 times.

Su Meng couldn't help but show a disappointed expression, in the simulation in his mind, this alloy should be stable, and its radiation value would not exceed 0.1 times the standard strength, but now the radiation value is so high, it can only be said that it has failed. Such a high emissivity means an extremely high decay rate, and it will not take long for this alloy to decay into other elements and lose its original material properties.

Originally, Su Meng calculated that the strength of this alloy was 800 times stronger than that of diamond, and it could accelerate the spacecraft to 80% of the speed of light after success, but now this alloy has no way to exist for a long time, and even Su Meng has calculated that its half-life is only 2 and a half years.

The alloy currently used by Su Meng is titanium-hydrogen alloy, which is 2.7 times harder than diamond, and the failure of this new heavy element alloy tells Su Meng that in this universe, heavy elements are an element that is suppressed, an unknown factor, making the decay rate of heavy elements exceed the decay rate she simulated.

This means that it is impossible for Su Meng to make a heavy element alloy that can last for a long time, and this path has been proven wrong.

Su Meng had to consider the various elements that already existed in the universe, all she had been simulating in her mind before were various metal alloys, titanium-hydrogen alloy was the product of her inspiration when she was on Earth, and later it was actually made on Mars.

Compared with the polymer materials used in the previous human future, the titanium hydrogen alloy has better heat resistance and durability, and more importantly, the strength of the human future can only support the speed of tens of kilometers per second, otherwise it will collapse, and Su Meng's titanium hydrogen alloy spacecraft can support 30% of the speed of light, which is incomparable between the two, there is a huge gap.

Su Meng began to experiment again, this time focusing on alloys that combine gas and metal elements, trying to create metals that are stronger than titanium-hydrogen alloys.

Ten years have passed, Su Meng has experimented with thousands of materials, and it has been proved again and again that titanium-hydrogen alloy seems to be unsurpassed, the closest one is krypton trivalent ferrosilicon sulfide, and the hardness has reached twice that of diamond, but the hardness of this bell alloy is only twice that of diamond, and there are many gaps from titanium-hydrogen alloy, not to mention others.

The long-term experiment also made Su Meng understand that the elements in the universe are the same everywhere, and what he sees when exploring the starry sky must be the product of these elements, so that Su Meng's fear of the universe is almost invisible, and he feels that the starry sky of the universe is like a somewhat strange home.

The failure of chemistry made Su Meng have to temporarily stop continuing the test of new materials.

Ten years have passed, Su Meng has almost no hope of making a stronger light element alloy, and the heavy element alloy, although it has a strong hardness, but it cannot be stored for a long time, and it is not of much significance to make a spaceship that can only exist for more than a year or two years.

The main element in the universe is hydrogen helium, followed by the heavy elements that form planets.

Heavy elements come from the Big Bang of star destruction, while elements come from the explosion of the birth of the universe, and it seems that all new life is related to explosions.

Su Meng hugged her sister and left the experimental area and returned to the rest area.

Put my sister on the bed in the villa room and wait for my sister to wake up.

Su Tian woke up from her sleep, stretched slightly, and saw her sister looking at her beside her, she didn't feel surprised, she was almost used to the current situation.

"Sister, how long has it been?" Su Tian asked.

"It's another decade." Su Meng said.

"Oh" Su Tian nodded, and couldn't help but sigh in his heart, it's been another ten years.

"Forty-five years to go, sister." Su Tian said.

"Yes" Su Meng nodded, now the distance from that star, there are still a little more than 14 light years, and it will take another 45 years to get there.

"Hmm" Su Tian nodded, sat up from the bed, she found the laptop on the table, and then opened it.

She found her previous research on black holes on the computer and looked at it for a while.

"Sister, where are we going to play later?" Su Tian said.

Su Meng showed a faint smile and said, "Wait a minute, my sister will take you to play a virtual game." ”

"Virtual games, what's that?" Su Tian asked.

"You know the virtual headset, right?" Su Meng said.

"Hmm" Su Tian nodded, of course she knew that when she didn't leave the earth, there was a time when virtual helmets were all the rage on the earth, but unfortunately the technology was not mature at that time, so she could only use the helmet to play some very simple games.

"My sister is going to help you get a virtual game to play." Su Meng said.

"Thank you, sister." Su Tian said with a smile on the corner of her mouth, at this moment, she was faintly looking forward to it, the virtual game made by her sister would definitely not be the kind of immature toy on the earth, and she couldn't wait to try it.

"Sister, let's study with me." Su Meng said.

"Hmm" Su Tian nodded, although she was afraid of zombies, but she was interested enough in studying virtual helmets, although she liked to follow her sister to eat and wait for death, but if she could study with her sister, it might be a very good life.

Su Meng took Su Tian to the basement of the villa in the rest area.

Then Su Meng started to create an experimental table.

It was in this basement that the sisters began experimenting with a new high-fidelity virtual projection helmet.
