The distance that the Earth travels in the universe in a year

One year in space is equivalent to one year on Earth. People say that the year is pressedThe earth revolvesweek to calculate.

Space refers to a place other than Earth, and there is no concept of time in space, so time in space is the same as time on Earth, so one year in space for an astronaut is equal to one year on Earth.

In ancient Chinese mythology, there is a saying that one day in the sky is equal to one year on earth, which is just a myth at the current stage of science, but if you use the theory of relativity.

Theoretically, it could become a reality in the future! It seems that the Chinese ancient chain core people have a certain understanding of the fundamental laws of the universe.

Time in space is strictly indistinguishable from time on Earth. But the calculation is different, like the Moon.

Its day is what our Earth calls a month (Earth Concept Time), and our Earth's day is 24 hours, which is calculated according to the Earth's cycle around the Sun. In this sense, time on earth and time in space are different. There is no unit of calculation for space time.

When it is about 7,000 meters away, you can clearly see the whole earth in this case, and you can also observe the color of the earth, which is also called blue marble.

People should need to stand outside the surface of the earth more than 7,000 kilometers in space, so that they can clearly see the whole earth.

You need to be about 1,000 km away to see the whole earth. It can be said that it is very far. That's a long way to go.

It should be super super far away to see the earth, the earth is the home of human beings, we have to take good care of it, and the earth is a water blue planet is very beautiful.

One has not yet been able to calculate how long the year of the universe is.

Geophysicists divide atmospheric space, or airspace, into 5 layers. troposphere, sea level to 10 km. The troposphere has dense air called a dense atmosphere.

The air in the dense atmosphere becomes thinner and thinner as the altitude increases. Stratosphere, between 10-40 km. Middle layer, 40 80 thousand chain grandchildren.

80-370 km is the thermosphere, which belongs to the lower part of the ionosphere. The outer atmosphere, more than 370 kilometers of space, belongs to the upper part of the ionosphere. From the Earth's surface to an altitude of 100 kilometers, there is less and less air as the altitude increases.

About 75% of the atmosphere above the Earth is in the troposphere and 97% below the stratosphere.

The universe outside the Earth's atmosphere, the whole space outside the atmospheric space. Physicists divide greenhouse gas into five layers: troposphere (sea level up to 10 km), stratosphere (10 40 km), mesosphere (40 80 km), thermosphere (ionosphere, 80 370 km) and outer atmosphere (ionosphere, above 370 km).

About 3.4 percent of the atmosphere above the Earth is in the troposphere and 97 per cent below the stratosphere, the outer edge of which is the maximum limit for aircraft to fly with air support.

Some high-altitude rockets can enter the middle layer. The lowest orbit of an artificial satellite is within a thermolayer, and its air density is 1% of the Earth's surface. Air continues to exist at altitudes of 10,000 km, and there are still airborne particles even at altitudes of 100,000 km.

From a strictly scientific point of view, there is no clear boundary between the air space and the outer layer of emptiness, but gradually merges.

The farthest distance that humans have discovered by exploring the universe is a galaxy named "UDFY-38135539" at a distance of 100 million light-years from Earth.

Astronomers have discovered the farthest galaxy to date from Earth and named it "UDFY-38135539". The galaxy is 100 million light-years away from Earth. Never before have we ever discovered such a distant galaxy with stars, gas, and dust.

The galaxy is so far away from Earth that when scientists observe it, it is still in the early stages of formation, about 6 million years old. This is only 4% of their current age.

udfy-38135539: (aka:.)"") is the most spectrally confirmed object (as of October 2010) UDFY-38135539 is located in the constellation Celestia, more than 4 billion parsecs from Earth, more than 13 billion light-years.

The galaxies' rays are redshifted to reach. In contrast, the previous record holder for the most distant celestial body, the gamma-ray burst GRB 090423, had a redshift of light.

Universe: It is the general term for all things, the unity of time and space. The universe is a material world, which exists objectively and does not depend on human will, and is in constant motion and development, with no beginning and no end in time, no boundary and no end in space.

The universe is diverse and unified; diversity in the diversity of material manifestations; Unity lies in its materiality. The universe is a unity of space, time, matter, and energy.

Light-year: is a unit of length, is a unit that measures the distance of light in a cosmic vacuum along a straight line for a year, generally used to measure the space-time distance between celestial bodies, its literal meaning refers to the distance of light in a cosmic vacuum along a straight line for a year, is 9460730472580800 meters, is calculated by time and the speed of light.
