Why is the Earth far away? Is the Sun always the same close to Earth?

Due to the effect of gravity on the earth itself, the gravity of the earth is directed to the center of the sphere, and under the action of gravity, the earth itself will be adjusted by gravity, and it has experienced vicissitudes and become what it is now.

Due to the surface tension of the liquid, the bubbles and small water droplets are round.

Why the earth is round begins with the birth of the earth. The original universe was a high-temperature, high-energy, high-density substance, and due to its large **, various planets were produced. At that moment, those planets were all hot and liquid, and also due to the action of surface tension, they were all round.

After hundreds of billions of years of cooling, the temperature on the surface of some planets gradually decreased, and then proteins were slowly produced, and life was born, and this planet is the Earth. In the various movements that followed, there was no reason to change it to other shapes, so it has always been in the circle until now.

So how do you explain the trajectory of the earth, is our earth a curvilinear trajectory? Let's create an illusion of light illuminated by visual effects.

Beijing, 16 Apr (Xinhua) -- According to a report by Lu Suyan, a reporter from Paris and Wu Weinong from Washington, scientists from many countries recently used the Hubble Space Telescope in the United States to photograph a celestial object 26 billion light-years away from the Earth, which is twice as far as the farthest known celestial body. At present, the astronomical community has not been able to determine the nature of this celestial body. Experts point out that this discovery challenges existing theories to explain the universe.

Researchers participating in the Sloan Digital Sky Exploration program deduced this celestial distance based on the law of redshift. Members of the program include astronomers from places such as the United States, the European Union, and Japan. Redshift refers to the transition of the electromagnetic spectral lines of celestial bodies observed from the Earth towards the red end, that is, to the longer end of the wavelength.

It is produced by the regressive velocity of the celestial body, and the farther away the celestial body, the greater the redshift. Previously, the highest redshift observed by the astronomical community was 6 68, which corresponds to about 14 billion light-years from Earth. The Hubble Space Telescope captured this object with a redshift of 12 5.

From this, the distance between this celestial body and the Earth should be 26 billion light-years.

It is reported that the discovery came as a great surprise to astronomers. According to the currently accepted grand ** theory that explains the birth of the universe, the universe was formed from a small dot** about 14 billion years ago, and the universe is still expanding. The age of the universe can be determined based on the distance of the farthest celestial body from the Earth.

According to the principle of relativity, the distance between a celestial body and the Earth is calculated using the fastest speed of light in the universe. If a celestial body is 14 billion light-years away from Earth, it means that light will travel 14 billion years to reach Earth. The farthest object ever discovered is about 14 billion light-years from Earth, indicating that the age of the universe is at least 14 billion years.

The farthest object discovered is 26 billion light-years away, indicating that the light emitted by this object traveled 26 billion years to reach Earth, which means that the age of the universe may be much older than originally thought. Experts believe that the contradiction between this finding and the original theory indicates that either the observation process is wrong, or the original theory needs to be revised.

NASA's Swift satellite has observed an object about 13.1 billion light-years from Earth. This celestial body was formed 100 million years after the universe was formed, and it is the farthest celestial body from the earth that has been observed by mankind so far.

The most distant object observed this time is actually a gamma-ray burst. The gamma burst was first observed by NASA's Swift observation satellite on April 23, 2009, and the gamma burst was named the GRB 090423. After the discovery, astronomers began to study the infrared afterglow of the gamma burst using observation equipment such as the British Infrared Telescope on the island of Hawaii and the Gemini North Telescope.

Astronomers have found that the gamma burst is about 13.1 billion light-years away from Earth. Ido Berger, a scientist at the Harvard-Smithsonson Center for Astrophysics in the United States, is a member of the Gemini North Telescope observation team. According to Berger, "This is the farthest gamma burst from Earth, and the farthest object ever discovered in the universe."

To calculate the distance of the 090423 gamma burst from Earth, astronomers first measured the distance the gamma burst's rays extended and how much it turned red using the expanding-space method. Measurements have shown that the gamma burst is approximately farther away than all previously discovered gamma bursts. The previous redshift value was recorded only.

Gamma bursts at such a distance also mean that the dead star should be the earliest object since the so-called "reionization period". It is understood that a gamma-ray burst is a phenomenon in the universe in which gamma rays suddenly intensify. Gamma rays are electromagnetic waves with a wavelength of less than nanometers, and are a type of radiation that is higher than the energy of X-rays, and its energy is so high that it can wipe out any life on nearby stars.

Any gamma-ray burst within 6,000 light-years of Earth would be able to destroy the ozone layer, thereby destroying the planet. Ignoring the properties of its metallic particles, such a destruction is possible every billion years, but it may be that the high metal content in the Milky Way keeps the Earth protected.

The Northermann Galaxy is 3 trillion light-years away from the Milky Way inside the news.

Does a little farther or closer to the Sun have an impact on the Earth? What are the implications?

The earth is a star inhabited by human beings, the planet is full of life, there is a lot of life, but this is also the only living star on the planet of the solar system, and it is also the only living star among all the planets we have observed, because the standard of life can be formed is too strict, life must have water, and the temperature can not be too high, not too low, of course, this is only the establishment of our earth life requirements, does not mean that the entire universe of life must be produced under this condition, However, these standards are already very strict, which will cause the birth of the earth to turn back as if it were an accidental event.

The distance between the Earth and the Sun is just rightEarth is the third largest planet in the solar system to be close to the sun, so to speak, the distance from the sun is just right. If the earth is far away from the sun, just like the sparks, Venus, and Jupiter, the sparks are used as an example, the structure of the sparks is actually very similar to the earth, and they are called sisters, but because the sparks are too far away, the temperature is too low, and they fail to produce life in the end; And if the earth is too close to the sun, it will be like Uranus and Mercury, all the stars will continue to be hot for a long time, the surface temperature will reach more than 1,000 degrees, and it is almost impossible for life to be born, so the distance between the sun's rays and the earth is very important.

The accidents on the earth invite everyone to reverie,After understanding that it is not easy for the earth to form life, some people will gradually raise questions, because the generation of life on the earth is indeed too accidental, just like people now carry out experiments on a creature, all the necessary conditions for survival are prepared, so everyone gradually speculates that people are the subject of research on breeding, some people will speculate that maybe life on earth is the offspring of aliens, and the origin of human beings is accompanied by colonization, but modern science and technology have not come up with a reasonable explanation. I firmly believe that along with the scientific concept of development, we will eventually find a place to belong to human beings.

The distance between the earth and the sun, whether it is farther or closer, is a disaster for mankind. The birth of life on the earth is not only due to its own conditions, but also because of the proper distance between it and the sun. You know, even a small change in the distance between the Earth and the Sun can cause a drastic change in the temperature on the Earth, and the planets lining up before and after the Earth are a good example.

If the distance is too close, the temperature of the earth will increase, and the impact on the earth's organisms is also very serious, if the distance is too far, the surface temperature will decrease, and even a large area of glaciation will occur.

If the distance between the earth and the sun is too far, it will be as cold as Mars, Uranus, and Neptune, take Mars as an example, the structure of Mars and the earth are actually very similar, and they are called the two sisters, but because Mars is too far away, the temperature is too low, and life is not formed in the end;

On a microscopic scale, the Earth is indeed getting farther and farther away from the Sun.

In the era of the Sun's main sequence stars, due to the tidal action of the Earth on the Sun, that is, the kinetic energy of the Earth, coupled with the action of the solar wind, it is basically a few centimeters away every year. But this is simply unchanged for the distance of 100 million kilometers between the Sun and the Earth.

When the sun transforms into a red giant, it depends on the intensity of the solar expansion and the strength of the solar wind at that time, so there are two situations: one is that the earth gradually moves away from the sun under the impetus of the sudden strong solar wind, and finally becomes a cold interstellar wandering celestial body, that is, farther and farther away; The second is that the thrust of the solar wind is not as fast as the rapid expansion of the sun, so the fate of the earth will be vaporized by the high temperature of the sun's surface and swallowed by the sun, that is, closer and closer.

It may be farther and farther away from the earth, because the earth rotates in a circle at 23:56 minutes and four seconds, and it is calculated by scientists as 24 hours, a few minutes a day, which is likely to form a physical difference. Plus the sun's orbit is constantly changing, making it more likely to appear. And what we often call the expansion of the universe, too.

You are wrong, the earth is in the solar system, the solar system is in the Milky Way, that is, we are also in the Milky Way, not the earth does not belong.

Even if astronomers always say how many light years are away, although the light year is the most common unit in astronomy, but it is not as simple as words, you think that 1 light year is very short, and it is known that 1 light year is the distance traveled in one year, and the speed of light in a vacuum is about 300,000 kilometers in US seconds. 1 light-year is easy to say, but it's a distance that would still be out of reach even if it took a person a lifetime with the fastest flying machine in the world.

Now the most manned spacecraft is to send humans to the moon about 380,000 kilometers away from the earth, the next goal is to send humans to Mars, to Mars now at the fastest will take half a year, but manned landing on Mars is still a big technical difficulty, after all, manned space vehicles need to maintain human survival, and maintaining human survival in space for a long time is a very difficult thing, a little problem may kill people, unlike the space station and ground supplies, If you embark on an interstellar journey without any ground supplies and have to be self-sufficient, you can imagine for yourself how difficult this is.

If it is an unmanned probe, many have been launched, such as Voyager 1, Cassini, Curiosity, Spirit, China's Chang'e-1 and 2, and Chang'e-3 will be launched this year to achieve a soft landing on the moon. Voyager 1 has flown past Pluto into the Kuiper Belt, but it still hasn't left the solar system.

How many light-years is the farthest galaxy ever discovered?

At present, people can go as far as the moon. The unmanned sounding equipment has already left the solar system.

Fly out of the solar system in a limited amount of time and reach the Milky Way, but never fly out of the Milky Way.

At present, the farthest human beings have left the earth is the Apollo moon landing, which is about 280,000 kilometers away from the earth;

The artificial satellite is only tens of thousands of kilometers away from the earth (apogee), and if it is too far away from the earth, it is not called an artificial satellite;

The Artificial Space Probe Traveler has been flying for thirty-six years now, flying tens of billions of kilometers, billions of kilometers from the Earth, and has long since entered interstellar space beyond the solar system, and is still sending signals back to the Earth!

Today's technology is able to know the microwave background radiation of the entire universe.

Humanity is rushing out of the solar system!

Voyager No. 1 (below paste).

At 12:56 on September 5, 1977, he departed from Cape Canaveral Air Force Base in the United States and left Earth.

In December 1977, he caught up with his twin brother "Voyager 2", who was the first to leave Earth.

It left the asteroid belt in September 1978.

In March 1979, I "visited" Jupiter up close and saw the aurora on the back of Jupiter.

In November 1980, he "visited" Saturn at close range and sent back more than 10,000 color paintings**.

In 1989, it headed for the center of the Milky Way.

The edge of the solar system was reached in May 2012.

In June 2012, the probe, traveling at a speed of about 17 kilometers per second and about 18 billion kilometers from Earth, reached the edge of the solar system and is expected to become the first man-made object to break out of the solar system.

If the Sun were very close, the Earth would be like Mercury, and the ground temperature would reach more than 300 at night.

And water will appear as a gas, and there may be no atmosphere.

If it is far away, the Earth will be like Pluto, the temperature on the ground will be very close to absolute zero, and the water on the ground will be in a solid form.

It doesn't matter if it's very close or far away.

None of them meet the conditions for the appearance of life in the forest.

So it doesn't matter how far away or very close.

It is impossible to be stupid that Chunji has humans.
