Fooling Tomoko into being a system

The biggest disaster in the three-dimensional universe is the two-dimensional expansion caused by the two-dimensional foil. Human civilization will naturally conduct in-depth research on the characteristics of the two-dimensional expansion.

Space dimensionality reduction releases no energy or a small amount of energy.

Dimensionality reduction of matter. Falling from high dimensions to low dimensions will release a large amount of energy. It is speculated that the higher the mass of matter, the more energy it releases when it falls. This is consistent with the characteristic that the energy level of the high-dimensional universe is higher.

It is precisely based on this characteristic that human civilization believes that energy life can seamlessly reduce dimensions, and energy has great versatility in different dimensions.

Human civilization has already collected data on the energy released when four-dimensional debris falls into the three-dimensional universe. As long as it takes a while to find a digital human in two dimensions, it is possible to obtain the data on the energy released when three-dimensional matter falls into two dimensions, and combine the two data. Comparisons will naturally yield useful data.

Low-dimensional matter will not be destroyed when it comes into contact with high-dimensional space, and high-dimensional matter will be expanded (destroying the material structure) when it comes into contact with low-dimensional space.

The reason why the singer civilization can survive in the virtual world in the two-dimensional universe is most likely because it uses two-dimensional matter to create a two-dimensional super-core central processor in three dimensions, and then sends three-dimensional digital life into the two-dimensional virtual world.

Then there is the key issue, the three speeds, namely escape speed, fall speed, and diffusion speed.

The most well-known is the escape velocity. When your galaxy has a two-way foil unfolding, only the speed of light can escape the scope of the two-way foil.

Escape velocity also involves the concept of "fall zone". There is such an area in the three-dimensional universe that is close to the two-dimensional universe but has not yet fallen into the two dimensions for the first time. This is called the "fall zone".

Escape velocity is exactly the speed at which you can escape from the 'fall zone' and out of the two-way foil attack range.

The fall speed refers to the speed of falling from a high dimension to a low dimension. In the original work, humans on earth watched the sun, the buildings around them, and humans become two-dimensional. This is the fall speed.

The falling speed is not fast at the beginning, as evidenced by the fact that the human eye can see that buildings have fallen into two dimensions one after another, but as the two-dimensional universe expands, the falling speed will accelerate.

Human scientists have various hypotheses. For example, the initial falling speed of the two-way foil may have been artificially modified, because the two-dimensional foil is a compressed two-dimensional fragment that loses its position constraint and expands rapidly. This is obviously a characteristic after being compressed.

After observing two-dimensional fragments of different sizes in the universe, it was found that the falling speed is also different with the different sizes of the two-dimensional fragments. The larger the fragments, the faster the speed, up to the speed of light.

Finally, there is the diffusion speed of two-dimensional debris, which usually refers to the diffusion speed of low-dimensional space in high-dimensional space. It is also the most concerned issue of all three-dimensional civilizations. The faster the diffusion speed, the sooner the end of the universe.

According to ordinary people's understanding, the two-dimensional fragments will accelerate to the speed of light after unfolding and continue to swallow the three-dimensional universe.

Assuming that a light-speed spacecraft approaches the two-dimensional universe but is not captured by the 'fall zone', a large enough two-dimensional universe will chase the light-speed spacecraft at the speed of light. The light-speed spacecraft can only escape in the opposite direction to avoid being swallowed by the two-dimensional universe. .

But according to the original work, Cheng Xin flew out of the solar system in a light-speed spaceship and arrived at Blue Star in 286 and accidentally fell into the black space. He escaped 1890 million years later and was not swallowed by the two-dimensional universe?

This can explain that the blue star is in the black domain, which is approximately equal to the low-light speed black hole, and the time is different from the time of the outside universe. However, this statement is far-fetched and unconvincing.

There is a more mathematically sound explanation that answers this question.

The diameter of the solar system is about 1 light-year for easy calculation. As the two-dimensional universe becomes larger, the falling speed is calculated according to the speed of light. However, the three-dimensional universe is a three-dimensional space, not a unit of length.

The three-dimensional expression of the two-dimensional universe only has front and side surfaces. The formula for the three-dimensional space area that can be swallowed up every year is: π0.5?*1 light year*2 sides=1.57 cubic light years.

然后再计算需要吞噬的三维空间面积，以太阳系当中心点到蓝星286.5光年作为半径，球体积公式为：4/3π286.5?=98456017立方光年。

98456017 cubic light years/1.57 cubic light years = 6272 million years, which is a long time from 1890 million years.

The diffusion of two-dimensional space cannot only be in the direction of the light speed ship, but spreads as a whole. It must completely swallow up all the space within one cubic light-year before it can continue to move forward. The three-dimensional space of the universe is not only distance. This is what the two-dimensional universe cannot do in 1890 million years. The reason for catching up with Cheng Xin.

This calculation process is an ideal situation. There cannot be only one two-way foil in the three-dimensional universe. Every time an additional two-way foil is launched, the swallowing speed will double.

Relying on the three-dimensionality of the universe, civilizations that master the speed of light can escape the engulfment of the two-dimensional universe.

However, this kind of light-speed civilization has very little scientific research time, and spends most of its time avoiding the two-dimensional universe. As the three-dimensional universe becomes smaller and smaller, it will eventually be caught up.

Decades later, human civilization upgraded its super-light distortion engine to 40 times the speed of light because of Zhuo Wen's discovery, and sent an advance fleet to the Mafi Galaxy Group in advance!

The straight-line distance is as long as 1000 million light-years. The immigrants of human civilization will settle through multiple galaxies rather than directly reaching the Maffei galaxy group.

One hundred thousand light-years later, the advance fleet flew out 400 million light-years, and human civilization finally began the era of great migration.

The great fleet of human civilization stopped and went between galaxies. It took 50 light-years, twice as long as the original plan of 25 light-years, and finally arrived at the Mafi Galaxy Group. The next immigration may be 950 million light-years away. after.

The specific time will be modified according to the current status of the universe, and may be accelerated or slowed down.

However, according to the tendency of most civilizations to randomly throw two-way foil as stones, human civilization most likely does not have 950 million years to develop.

Human civilization has changed its era name again, and the time when it reaches the Mafei Galaxy Group is called Mafei Era Year 0. This epoch will last up to 950 million years.

Thanks to the powerful 40 times faster-than-light distortion engine, Ma Fei humans have led countless civilizations to their targets, and have time to observe the civilization behind them with super core + big eyes.

Human civilization concentrates on studying quantum ghost technology and sends super-light spacecraft to explore the center of the universe and the Virgo galaxy cluster!

Time - 500 million years of Maffei's era!

With the help of the distortion engine, human civilization has thoroughly understood the details of quantum ghost technology and is moving towards weak quantum life.

Human civilization has discovered many wakes left by light-speed spacecraft in the distance between the local galaxy group and the Maffei galaxy group, and discovered cosmic war outbreak radiation and electromagnetic waves between the Sculptor galaxy group...

Human civilization speculates that the two sides are immigrants from the local galaxy group and the Sculptor civilization.

To a large extent, it proves that human civilization made a wise choice in not choosing the 7 o'clock emigration route of the Virgo Super Galaxy Cluster. The new generation of humans can only lament again that this is a miracle for hibernators.
