If you look at the earth from 2,200 light years away, can you witness the ancient Qin and Han dynast

There are many times when we want to travel back to ancient times to see what kind of life people lived at that time, and now it is impossible for human beings to realize crossing, and there are many mysteries of the universe that have not yet been solved by human beingsSo if you look at the earth from 2,200 light years away, can you witness the ancient Qin and Han dynasties? Theoretically, the ancient Qin and Han dynasties can be seen 2,200 light-years awayLet's break it down. <>

We all know that many time-traveling dramas are fake, and many excellent film and television works also mention the exchange of time and space in the storyline, or because of something that caused the protagonist to travel to ancient times, and then triggered various stories in ancient times. We usually watch the time-traveling drama, it is very difficult to realize or cannot be realized through time and space, and our current level of science and technology is completely unable to construct a device that can travel through it. We all know that the propagation speed of light has been discovered by us humans and defined as 300,000 kilometers per second, and the length of the path of light in a year is one light year.

Observing the earth 2,200 light-years away, we can logically see the Qin and Han dynasties 2,000 years ago, but we have to reach that place at this time to see how fast we can teleport. But the reality is really cruel, first of all, we humans can't get to that place so quickly, and secondly, our earth is a planet, and it doesn't shine like a star, and it is very likely that we won't be able to observe the earth 2,200 light years away, or we can't see it. <>

When it is hot, it is true that the sunlight of 2,200 years ago can be felt 2,200 light-years away from the Earth, and it will be extremely tiny to see the Earth from such a distance, unless we can directly see the surface of the Earth. The relationship between light and space is very delicate, but I believe that in the future we humans can do interstellar travel.

No. Because there are many planets within the range of 2,200 light years, which will block the light, it is impossible to witness the ancient Qin and Han dynasties.

If you look at the earth from 2,200 light years away, you can't witness the ancient Qin and Han dynasties, because there is no time going backwards, and time is passing every day.

Many times we want to go to ancient times and see what kind of life people lived at that time. Now, it is impossible for humans to achieve crossing. There are many mysteries that humanity has yet to solve.

So if it's in the year 2200, if you look at the earth a year away, can you see the ancient Qin and Han dynasties? Theoretically, the ancient Qin and Han dynasties could be seen 2,200 light-years away. Let's analyze it.

Twenty-two light-years away from Earth can't see Qin Shi Huang's image, because we can't. Even no matter how advanced the technology is, it's the same, so don't look at Qin Shi Huang anymore, it's terrible.

In fact, it is theoretically possible, but it is really impossible to see the image of Qin Shi Huang from 2,200 years away from Earth, even with an astronomical telescope.

At a distance of 2,200 light years from the earth, you can see the image of Qin Shi Huang, in fact, some scholars believe that this is true, and it is also said that the true god has been recorded in historical records, so it can be said that Qin Shi Huang should have been grand when he ascended the throne at that time.

Regarding whether there is a time lapse in the universe, Hawking only proposed that it is theoretically possible to go through wormholes before his death. But after all, wormholes are not yet what our human civilization can currently build.

If you go to 2,200 light-years away and observe the Earth, will you be able to see Qin Shi Huang?

In fact, we can see the image of Qin Shi Huang in our mobile phones.

We can only learn about Qin Shi Huang through relevant texts and cultural relics. But from a physical point of view, if the technology of the future is developed enough, we can theoretically see Qin Shi Huang, just like watching a TV picture.

On planets farther away from Earth, you can see the Earth earlier. For example, if there is a very advanced alien civilization around Sirius light years away, then they can see the Earth from years ago, because the light from the Earth just traveled here.

What happened on Earth did not disappear there, but was preserved by the universe. Qin Shi Huang lived about 2,250 years ago, when the light reflected from the Earth is still traveling through the universe and is now 2,250 light-years away from the Earth. 2,250 light-years away, light reflected from the Earth 2,250 years ago can be received, so you can see what happened on Earth 2,250 years ago, including Qin Shi Huang, who was unifying the Six Kingdoms.

It is not possible at the moment. First of all, we don't have enough technology to support it. If we want to see the images of 2,200 years ago, at least at the speed of light to catch up with the images that have been running for more than 2,200 years, we will not be able to reach the speed of light at all, let alone the speed of light.

Images are attenuated in the process of propagation, not to mention such small details, it is difficult to preserve them completely thousands of years later.

We want to achieve the ultimate speed of instantaneous displacement of 2,000 light years, which is basically impossible for human beings to do with the current theory, unless we turn the theory of quantum entanglement into reality, and can ignore the dangers of radiation and floating in the universe, and where to move at the speed of quantum entanglement. Even if humans were to travel at the speed of light, it would take more than 2,000 years to reach 2,200 light-years away. And when people really walked to a place of more than 2,000 light years, the information of Qin Shi Huang's enthronement on the earth has reached a place 4438 light years away, which also means that people will never catch up with Qin Shi Huang's accession to the throne.

The general environment of the universe is not as peaceful as people think.

I don't think so. Even if there is really a way to travel through time and space, Qin Shi Huang, as an emperor, is not something that ordinary people can easily see.

Qin Shi Huang can be seen. Because the light that can be seen 2200 light years away is 2200 years ago. But this will not happen, because the current scientific and technological conditions have not yet been met.

I don't think I can see Qin Shi Huang, because Qin Shi Huang is dead, he no longer exists in this world.

Traveling through time and space has also been an important topic for a long time. Some people even say that standing more than 2,000 light years away, we can even see the glorious Qin and Han dynasties. This goal could be achieved more quickly if the area was accurately reached and the Earth was observed.

Scientists have questioned the unrealistic nature of this idea, as it is not enough to travel through time and space in a variety of ways.

As a unit of distance, the light-year does not have the function of spanning time and space

As early as primitive times, people knew how to calculate time according to the alternation of day and night, and measured the approximate duration of all work, and thus came the biological clock, etc., and many living things existed in similar states.

Although this idea is very common, there is no real time in the strict sense of the word. Especially in Einstein's theory of relativity, everything is relative, all moments are equal, so there is no past, present, and future.

As a unit of distance, the light-year does not have the function of spanning time and space, and the activity of galaxies or celestial bodies tens of millions of light-years away is only a lag after the phenomenon occurs. It takes tens of millions of light-years for light to reach the earth until it is caught.

So if you want to stand more than 2,000 light-years away and see the Earth at that time, the results are not surprising. This is because the earth does not change its own light, and it does not leave any images of that time.

The past, present, and future do not exist in the physical sense

In fact, the so-called past, present, and future are completely non-existent in the physical sense, and all the time we experience is a strange illusion. From Newton to Einstein, many physicists believed in this statement, but no one was willing to truly accept reality.

But photons also keep escaping, and in the thousands of years of activity of the earth, photons also disappear with the passage of time. Therefore, even if we have the relevant technology, it is difficult to find the complete photon information to recover.

Standing 2,000 light-years away, although it is really insignificant compared to the diameter of tens of billions of light-years in the universe, our current technical means still can't reach that far.

Time plays a role similar to a chain, and it is unrealistic to travel through time and space

In Newton's laws of motion, time plays a role similar to that of a chain, and all motions are connected by time in a sequential order.

Later, some physicists extended Newton's statement and came to the conclusion that Newton's laws of motion were applicable to both forward and reverse time, which provided a certain theoretical basis for Einstein's theory of relativity.

The discussion of time never stops, because it is not only a physical change, but also the boundaries of the concept of time are of great significance to the development of philosophy and human society as a whole.

From the point of view of physics, time cannot exist alone as a unit or dimension, and gravity can have a huge impact on time, which is called "time travel".

Space travel has always been a topic of curiosity, and these two events have influenced all kinds of people for thousands of years. But some people say that as long as you stand for more than 2,000 years, you can see the Qin and Han dynasties, and you can observe the earth, and your goal will be achieved. But in reality, this idea is completely unrealistic, and it does not have the ability to cross time and space.

Scientists have also specifically questioned this, because it is impossible to cross distances now because of the various conditions that need to be met to cross time and space.

First, it is unrealistic to use light years as a unit of distance, and the key is not the ability to cross time and space. In fact, as early as the primitive times before that, we already knew how to use day and night to calculate time and measure work, and we also made a biological clock. It's a similar situation with a lot of creatures now, but the concept is more common and not really time.

In Einstein's theory of relativity, everything is relative. If you take light years as the distance unit, there is no way to cross time and space, and tens of millions of aliens or some celestial activities before the Chinese New Year can be observed, which is only a lag after the phenomenon appears.

Second, in fact, it has been a long time since we went directly to Earth and were captiveIt would take about a few thousand light years. If you want to stand for more than 2,000 years and see the results of the earth, there is no way to surprise people, because the earth itself does not say that there are some changes, and there will be no images left, the past, the present and the future do not exist in a physical sense, and everything in the present is an illusion.

3. Photons can record everything, but they can't capture the activity of photons. If you want to recreate the original scene, you have to record it. The invention of the camera was based on the relevant principles.

Photons are actually constantly passing away and disappearing, and will cease to exist over time. Standing more than 2,000 light-years away, although it is tiny compared to the diameter of tens of billions of light-years in the universe, our current technological means still can't reach that far, and time plays a role similar to a chain, and it is unrealistic to travel through time and space.

Yes, it is true, if we can exceed the speed of light, then standing in the place more than 2,000 years ago, we can see the glorious Qin and Han civilizations.

Depending on what tools are used, the human eye must not see them, with the help of astronomical instruments, aliens can.

No, it must not be visible, the human eye does not have that far vision.

It doesn't have to be rough, because even if you can travel back in time, you can't travel to any moment in history, which has something to do with the distance between the celestial bodies and us, so you can't really see the rocks.

Yes, it can be seen because the light is traveling, and at a distance of 2,200 light years, there is a good chance that there will be light that existed in the time of Qin Shi Huang.

It's a friendly gesture; Because Qin Shi Huang lived in a dynasty that imitated us 2,200 years ago, if our science and technology reached a certain level, then it would definitely be a balance that could be seen.

This is a conundrum at the intersection of time and space.

I want to ask if we can see Qin Shi Huang in an area 220 billion light years away? According to the basic theory, Qin Shi Huang can still be seen under the support of sufficient scientific and technological progress.

The speed of light is the speed at which light travels, and the speed at which light travels is more than 300,000 kilometers per second. For example, the distance between the moon and the earth is about more than 10,000 kilometers, and it only takes 1 second to reach the earth from the moon alone. The distance from the earth to the sun is about 149.6 million kilometers, and it takes about 8 minutes for sunlight to reach the earth.

If we think of the sun's rays as a continuous gushing stream of water, and mark a stream of water, we will see it on Earth in eight minutes. Again, when you look at this sign on Earth, it's actually put out eight minutes ago.

We only live in the solar system, and there is also the Milky Way to which it belongs outside the solar system, and there are also many extragalactic galaxies, star orbits, super black holes and other celestial bodies. The distance between the celestial bodies is also very long, for example, my distance from the constellation Lyra, to which Vega belongs, will be 2.6 billion light years, which is the distance between 26 years of light. In other words, a beam of light from Vega will not reach the Earth until it reaches the Earth after a period of 26 years, and what you see is only from Vega 26 years ago.

And so on, if it's a longer celestial object, the greater the time difference between what we see. Today's scientists use lower magnification glasses to observe the condition of celestial bodies hundreds of millions of light-years away, that is, to see the future development of space 100 million years ago, and then expand to a longer period to explore the origin of the universe.

Now that everyone is pulling back to Qin Shi Huang, if there is a relatively developed civilization in an area of more than 2,200 light years now, and they can observe the Qin Dynasty on the earth in a delicate enough way, they can still see the impression of Qin Shi Huang. It's as if we can observe the past in the universe. However, there is a necessary condition for sufficiently developed civilized behavior and high and new technology.

Can people see it themselves? It is unlikely at this stage. First of all, everyone does not have enough high-tech support points.

If you want to see the image of 2,200 years ago, at least use the speed of light to chase the image that has been running for more than 2,200 years, and you can't reach the speed of light at all, let alone the speed of light. The attenuation coefficient of the image will be in the process of dissemination, let alone such a small key point, it is difficult to store it in detail thousands of years later.

In fact, it is unlikely that we will see Qin Shi Huang, which is like talking in physics: a way of exercise can always do a uniform linear fitness exercise without the application of other external forces. And in physical terms, there is not a single object that does that kind of fitness movement.
