One emperor through the ages, this is the simplest and most powerful summary of Qin Shihuang, so many people are very interested in such a domineering king, but unfortunately he was born at the wrong time, and it seems that we will never be able to really see him. To Yingzheng .
In fact, it is not necessarily true. According to modern science, it can capture the moon in the sky and catch dragons in the deep sea. There is really nothing that can stump it. Hehe, yes, theoretically speaking, we have a chance to meet Qin Shihuang.
Light year is a distance unit, representing the distance traveled by light in one year.
In 221 BC, Qin Shihuang officially unified the six countries and proclaimed himself emperor by taking the essence of Three Sovereigns and Five Emperors . It has been 2243 years ago. In other words, we only need to go to a position 2243 light years away from the earth to directly witness it. Qin Shihuang's ascension to the throne!
Deng Xiaoping once said that it doesn't matter the white cat the black cat, as long as it can catch mice it is a good cat. Talking on paper is ultimately shallow. No matter how popular theoretical science is, it must be verified by practice. So how can we verify this question about Qin Shihuang?
How do we teleport to a location 2243 light years away?
The first difficulty in wanting to see Ying Zheng in person is the race against the light.
Yes, if we teleport to a location 2243 light-years away by some means, we will be able to receive the light emitted by the earth at that time.
However, teleportation is too sci-fi and unscientific. We have to start from the earth and reach the destination step by step. In this way, we encounter new problems. We are racing against light.
Assuming that the traveling speed of your fleet is less than or equal to the speed of light, then you will never be able to see the light from 2243 years ago, because it is also moving forward while you are moving forward, and you always maintain a relative distance.
Let's put it this way, for example, your speed is exactly equal to the speed of light. When you finally reach the desired location, but the journey takes 2243 years, what you can see at this time is exactly the earth today. Qin Shihuang is still 2243 light years away from you. The position of the year is waiting for you.
This is not complicated, and it is consistent with a theory of Einstein . When your speed is greater than or equal to the speed of light, time can stop or even flow backward.
Observation methods
Then, the second difficulty in meeting Ying Zheng is observation. Assuming that you have arrived at a planet 2243 light-years away, what means should you use to observe the Earth that is far away?
Many people will say telescope without thinking, but in fact, astronomical telescope is not so magical at all. The farthest distance that the Hubble Telescope can currently observe is 12 billion light-years. This does not mean that any planet within this distance is within human vision.
First of all, the earth is not a star that emits heat. It is just a planet illuminated by the sun. Its surface can reflect part of the sunlight.
And when you reach such a far distance, the light that the earth can transmit is already very small. Using all the methods in the world now, you cannot observe a little light from the earth.
The farthest planet discovered by humans today is in the constellation Sagittarius, 5,000 light-years away. However, we have no idea whether this star has an atmosphere, whether it has mountains and rivers, or even why it emits so much light as a planet. The light is so intense that humans can observe it.
So even if we observe the earth from such a distance, it is like looking at the stars in boredom at night. At most, we can only catch a point of light. How can we say that we saw Qin Shihuang ascending the throne?
Conclusion
It is not impossible to see Emperor Qin Yingzheng with his own eyes. A pair of scuds that can teleport and a pair of clairvoyance that can see the stars in the universe are two necessary conditions to meet him.
However, scientists shook their heads to achieve such an incredible level of technology, and even science fiction novelists did not dare to think about it.
