Any civilization's understanding of something is proportional to what they see and hear. The more things they see, the higher their understanding will naturally be.

  What is light? What is its speed? In human cognition, the speed of light is kilometers. Because humans have never left the solar system, this limits their cognition. We have crossed countless galaxies, and our cognition is broader than that of humans. In our cognition, 290,000 kilometers per second is not the speed of light, but only a state of light.

  …

  "Is this all the data you have about the pyramids? Can't you reveal the other data to us? Or are you deliberately hiding it from us?"

  "You must understand one thing. On Earth, in the solar system, we are not free. Apart from the things happening inside our moon, our activities on other planets are restricted. We do have other data about the pyramids, but not much, because we are not allowed to enter the interior. The only data we have is what we see from outer space. The only other data we have is a number, which is just a time period. It means that 2040 to 2449 will be an important year. We don't know what will happen, but this number is indeed left to us and the people of Earth by the guardians. It has nothing to do with you."

  "Then could this number be related to the opening year of the pyramid? Will its hidden functions be gradually opened from this year onwards? When was this pyramid built? Have you done any research in this regard?"

  "It probably won't represent the number of years it has been opened, because the pyramids are often opened randomly. There is a secret passage connecting each pyramid, and the end of the secret passage is the stone statue that is still there. This statue was built to commemorate the contribution of their first generation of pharaohs. Of course, this is just a lie. Its purpose is actually to be a converter that delivers energy to each channel. It has a side door, but according to human technology, they can't find the entrance. This entrance is opened once every 99 years, sucking in enough energy from the outside world and then closing. So the number you said represents the number of years it has been opened, which is not very realistic. The reason why we say it is for us and humans is, We have a basis for our judgment, and this basis cannot be explained for a while. As for the construction period of the pyramids, we are not sure, but according to our calculations, it must be at least tens of thousands of years. After all, the civilization of the Gendaya has completely disappeared from the earth. The reason why we have such an inference is that we first know when they arrived on the earth; secondly, we have studied humans, and the limit of human historical records is only 10,000 years, and there are very few records of pyramids in human history, so the age of these pyramids must be more than 10,000 years. Regarding the history of the pyramids and Gendaya, we can only explain this, because this is all we know. "

  "Let's stop here with Ms. Ran Ping's explanation of the knowledge about the pyramids. It won't have much to do with you if I explain it further. After all, we can tell you what we can determine, and we won't tell you if we are not sure, because it is meaningless to talk about knowledge that cannot be confirmed without any evidence. So we should change the topic and change our thinking. We can discuss the knowledge you want to know about light. Light is a very incredible thing, and we haven't studied it thoroughly. Here I ask you a question. In your opinion, what is the speed of light?"

  "Our home planet is 130,000 kilometers per second"

  "Our home planet is 450,000 kilometers per second"

  "Shouldn't the speed of light be the same? Isn't the data given by the Alliance 350,000 kilometers per second? This is the data we have been using since we were born. Is this the first time I heard that the speed of light is different? This is too magical."

  "Of course it's different. Its speed depends on its own state and the cosmic environment it is in. Our research archives record that light is a wave and it can also be a particle. It is precisely because it can switch between different states at will that its speed is absolutely different. In any cosmic environment, as long as there is gravity, the speed of light will also be restricted by gravity. We use the solar system as a unit. Its gravity is equivalent to one, and its speed is 290,000. If you use 350,000, it is equivalent to that you can withstand more than one point of gravity. When you enter the solar system, you will not be affected too much. This one gravitational point is the unit we use. When we enter any new galaxy, we will first study the gravitational point of the galaxy, and then adjust the speed of our spacecraft. We don't have to worry about encountering a large gravitational point. What we are most afraid of is encountering a small gravitational point, because such an environment will tear us apart in an instant. This is the biggest obstacle many civilizations encounter when they begin to explore the universe..."

  "What if it was us?"

  "If it were you, then you would be able to withstand a higher gravitational point. If you were to fly at your speed, the moment you entered the solar system, your speed would instantly drop below 290,000. You should know what would happen."

  “What is the concept of this gravitational point?”

  "It has no concept. It is an invisible force that is affected by many factors. The most important one is the force of the entire galaxy. For example, the entire Milky Way is rotating, so light will also be affected by the rotation of the Milky Way, reducing some of its speed. In addition, the center mass of the Milky Way is very large, and the entire Milky Way is concave downward. The closer to the edge, the faster the light speed, and the closer to the interior, the slower the light speed. The second is the number of black holes within 999 light years in the area, because black holes will release gravitational waves. Every time a gravitational wave reaches the solar system, it will reduce the speed of light. Finally, there is the density of dark matter. The greater the density of dark matter, the slower the propagation speed, and the smaller the density of dark matter, the faster the propagation speed."

  "So what's your fastest speed of light?"

  "We almost never use the speed of light, because it requires too much energy. For us, time is irrelevant, energy is the most important. Our speed of light is 390,000 kilometers per second. Your 450,000 is not the fastest. According to our supercomputer calculations, in a 100% pure space environment, the speed of light would be 990,000 kilometers per second."
