Voyage of the Stars.

Chapter 755 Great Science

This time, humans obtained data on almost all relevant virtual lattices and physical lattices, and counted them together after all fleets had their turns.

Obviously, this is a huge amount of data.

You have to know that humans can reach about ten times the speed of light, and the voyage took about two years. Because it was a careful exploration, it could not always maintain the maximum speed, so after the exploration, it was found that this space is about ten light years in radius, as if it was a spherical space.

But it is obviously not a spherical space, but a space that is folded in an unknown way. Not only is it a folded space, but it is also a space that is connected end to end. Unfortunately, even if humans have visited it, they still don’t know what kind of folding structure it is. It feels like they are in the middle of a mountain.

In such a large space, there is a diamond lattice almost every 0.5 astronomical units.

A data system composed of so many 0s and 1s is undoubtedly very large, and it is not necessarily true that a virtual lattice can only represent one 0, and a physical lattice does not necessarily only represent one 1. Therefore, what is in front of humans is a bunch of permutations and combinations of numbers.

However, the solution to the combination is nothing more than an exhaustive enumeration. As long as the computer is powerful enough, it can calculate all the possible results in a short time.

As for what the possible outcomes are, there are many possibilities.

First, it could be a digital image like the animated image civilization at that time, because it is necessary to convey information to the new generation of civilization billions of years later, and it is possible to use the common light sense to convey information. Second, it could be an expression of some cosmic physical laws, perhaps mathematical expression, or physical expression, but this kind of expression requires knowing the code behind these 0 and 1, just like humans convert 0 and 1 signals into natural language.

If it is the second case, then humans still need to find the code hidden in this universe, which is a bit difficult. After all, after a tour, humans have found nothing except virtual lattices and physical lattices.

There is a third possibility, these numbers are just a bunch of pure numbers, they may represent some meaning. This possibility also requires humans to know the code behind virtual and real, in other words, what base is 0 and 1 represented in, and whether the mathematical system used by the pioneers is the same as that of humans.

从人类自己的角度看宇宙，其他文明用跟人类一样的数学系统是有可能的。这里说的一样数学系统并不是指1、2、3、4、5、6这样的数字，而是说其他问定义的1跟人类定义的1概念相同。

The writing systems are probably different, but the concept of 1 defined in each writing system is probably the same. This is because from the moment of the birth of wisdom, everything we come into contact with has a concept of shape, whether it is as big as the sun or the moon, or as small as an individual, a stone, or a pool of water, there is a concept of 1.

And in the process of life survival and growth, we will come into contact with various things with 1 concept.

Therefore, most mathematics starts from this concept. Even if a civilization has different innate cognition from humans, the world it comes into contact with is the same universe and the same starry sky. There must be a certain number of stars in the Milky Way, so their concept of 1 is likely to be the same.

It is for this reason that Galileo said that mathematics is the language of the universe.

With the concept of 1, there must be the concept that two stones put together are 2, and so on, mathematics was born. Mathematics was born in daily life, or it can be said that mathematics is in the universe and is a natural tool for intelligent life to understand the universe.

Of course, this is just a mathematical concept, and the units are definitely different. For example, the definition of meters by humans was very sloppy. At the beginning, this unit of length was actually defined by the length of a king's legs, just like "step". Emperor Taizong of Tang defined "one step" as one step with each foot. The ancient Egyptians who built the pyramids used the length of the pharaoh's arm as the unit of measurement.

This will inevitably lead to different meanings.
Of course, in 1983, the 1th General Conference on Weights and Measures adopted a new definition of the meter, which is the length of light in a vacuum in a time interval of 299792458/133 seconds. The second is 9192631770 times the period of the electromagnetic wave radiated when the two hyperfine energy levels of the ground state of the cesium atom transition.

In this way, mathematical values ​​are linked to the physics of the real world.

These are the definitions of the various physical units used by each civilization, and the hidden meanings behind every number used by each civilization.

Obviously, it is impossible for humans to know the Pioneer code.

So in the absence of any clues, guessing alone will definitely not work, unless you can find clues from these 0s and 1s.

So how do we find the clues hidden in these diamond-shaped lattices?

It has to be said that scientists are scientists. The first thing they think of is the speed of light, because many physical concepts are based on the principle of the constancy of the speed of light. The speed of light is also the most basic physical constant in the universe, and the universe is also isotropic on the time axis. Therefore, the speed of light billions of years ago must have been a constant just like it is now.

If the laws of physics have not been modified by a god-level civilization, the speed of light has been the same throughout history.

Therefore, scientists first measured the speed of light here, and then calculated how long it would take for light to cross the distance between the two diamond lattices. In this way, if the pioneers were not deliberately making things difficult, humans would know the relationship between the pioneers' 1 distance unit and the speed of light.

In this way, the mathematics of humans and pioneers have achieved mutual communication to some extent. Then we can guess which base the pioneers used, and finally use the exhaustive method to arrange and combine the relationship between various bases and the values ​​of 0 and 1, and we can get a lot of numbers, strings, and groups that are so many that they make humans' scalps numb.
The next step is naturally to analyze and observe these massive numbers with the assistance of strong artificial intelligence, and find the patterns among them.

It has to be said that every step here is testing the technological strength of a civilization. A civilization without the ability to travel at the speed of light cannot explore the entire space diamond lattice at all. Without powerful computer technology, it cannot complete digital calculations. Without powerful strong artificial intelligence technology, it cannot perform analysis.
And these abilities can only be achieved by reaching at least level four civilization.

In other words, the Pioneers' test subjects seem to require at least a Level 4 civilization.

If this is true, then humans can get a message: the things left behind by the pioneers can only be used by at least a level four civilization.

Science is so great that humans can now begin to understand the meaning left by their pioneers billions of years ago.
