Heliocentrism and why the Earth is moving

Copernicus created heliocentrism, Foucault confirmed the rotation of the Earth, and Bessel measured 61 parallax arcseconds in the constellation Cygnus.

The main idea of geocentrism is that the Earth is the center of the universe and is stationary, while all other planets orbit the Earth. The main idea of heliocentrism is the antithesis of the movement of celestial bodies, which holds that the sun is the center of the universe, not the earth.

The geocentric view is that the Earth is at the center of the universe and does not move. Each planet rotates at a constant speed in a small circular orbit called the "Wheel", and the center of the Wheel rotates around the Earth at a constant speed in a large circular orbit called the "Wheel", but the Earth is not at the center of the Wheel, but at some distance from the center of the circle.

The heliocentric view is based on the previous research doctrine that the earth is spherical. The Earth is in motion and rotates once every 24 hours. The sun is motionless, and at the center of the universe, the earth and other planets move in a circle around the sun, and only the moon orbits the earth.

The proposal of the heliocentric theory made the geocentric theory much less important than before, and it was gradually eliminated.

The "heliocentric theory" was proposed by Copernicus, and the "geocentric theory" was first the initial concept formed by the Miletus school, and later proposed by the ancient Greek scholar Eudox. The "heliocentrism" holds that the sun is the center of the universe, while the "geocentrism" holds that the earth is the center of the universe. Copernicus spent his whole life using accurate calculations and observations to prove the theory that the earth rotates and that the planets revolve around the sun, and rejected the "geocentric theory" that the earth is the center of the universe.

The theory of "geocentrism" was put forward earlier than Copernicus's "heliocentric theory", and although the theory that the universe is centered on the earth has been verified wrong by the modern level of science, its contribution to mankind is also indelible. At least the "geocentric theory" believes that the earth is spherical and distinguishes the planets from other stars, allowing scientists to focus on the motion of major planets, and promoting the development and progress of science.

"Another major contribution is the use of mathematical models to measure the motion of planets, and the design of a wheel equalization model, through which scientists can more accurately calculate the position of the planets, which is a remarkable achievement."

The only drawback is that the "geocentrists" did not know that their theories were wrong, so they were gradually replaced by the "heliocentric theory". The "heliocentric theory" is a theory put forward by Copernicus after years of research and observation, and it can only be recognized after a long period of verification of facts to make people accept the new theory. He proposed that the sun is the center of the universe and that the earth revolves around the sun as a year, and we have continued to use this scientific theory until now.

For example, the sun is not the center of the universe, but only a central celestial body in the solar system, and the earth is not round, but elliptical, but his contribution to mankind is still great and worthy of people's admiration.

Both the "geocentric theory" and the "heliocentric theory" put forward the idea that the earth is a sphere, and the "geocentric theory" holds that the earth is the center of the universe and is immobile, and all the celestial bodies around it revolve around the earth; The "heliocentric theory" holds that the sun is the center of the universe, the earth is in motion, and the planets and surrounding celestial bodies revolve around the sun.

Geocentrism".

1. The Earth is at the center of the universe and is stationary.

2. Each planet rotates at a uniform speed in a small circular orbit called the "Wheel", and the center of the Wheel rotates at a constant speed around the Earth in a large circular orbit called the "Wheel", but the Earth is not in the center of the Wheel, and this source is some distance from the center of the circle.

3. The center of Mercury and Venus is located on the line connecting the earth and the sun, the center of the current cycle rotates once a year on the mean wheel, and the straight line from Mars, Jupiter, and Saturn to their respective center of the wheel is always parallel to the Earth-Sun line, and these three planets revolve around the center of their current cycle every year.

4. Stars are located on solid shells called "sidereal days". In addition to the above-mentioned movements, the sun, moon, and planets also orbit the earth once a day together with the "sidereal heavens", so that various celestial bodies rise in the east and set in the west once a day.

heliocentrism".

1. The earth is spherical. If a light source is placed on the top of the mast, when the ship leaves the shore, the people on the shore will see the light gradually decrease until it disappears.

2. The earth moves by a number of moves, and rotates once every 24 hours.

3. The sun is motionless, and in the center of the universe, the earth and other planets move in a circle around the sun, and only the moon orbits the earth.

In the second century AD, the ancient Greek astronomer Ptolemy (90-168) founded the geocentric universe system, proposing that the earth is stationary at the center of the universe, and the sun, moon and stars revolve around the earth in a circular orbit day and night. For more than a thousand years, Ptolemy's geocentric theory was regarded as a classic by the world, and later used by the church as a theoretical pillar of God's creation of the world. In the century, with the improvement of social productivity and the development of navigation, the observation of celestial phenomena was promoted, and people's understanding of the universe began to undergo revolutionary changes.

In 1543, the Polish astronomer Copernicus (1477-1543) published his immortal work "The Theory of the Movement of the Heavenly Bodies", which put forward the theory of the center of the sun, arguing that the earth is not the center of the universe, the sun is the center of the universe, and the planets revolve around the sun; The Earth is an ordinary planet orbiting the Sun, itself rotating; The Moon is a satellite of the Earth, and the Earth orbits the Sun with the Moon; The planets are arranged in the solar system in the order of earth, wood, fire, earth, metal, and water, and their orbital periods are 30 years, 12 years, 2 years, 1 year, September, and 88 days, respectively.

Geocentrism was proposed by the ancient Greek scholar Eudox, and then gradually established and perfected by Aristotle and Ptolemy. The heliocentric theory was proposed by the Polish astronomer Nicolaus Copernicus.

Ptolemy believed that the Earth was stationary at the center of the universe. From the Earth outward, there are the Moon, Mercury, Venus, the Sun, Mars, Jupiter, and Saturn, which orbit the Earth in their respective orbits.

Among them, the motion of the planets is more complex than that of the Sun and the Moon: the planets move on the current wheel, which in turn orbits the earth along the average wheel. Beyond the Sun, Moon, and Planets, there is a celestial sphere stellar sky inlaid with all the stars.

Outside, there is the prime mover that moves the celestial bodies. Geocentrism is the world's first model of a planetary system.

Copernicus's "heliocentric theory" effectively broke the "geocentric theory" that had dominated religion for a long time and brought about a fundamental change in astronomy.

Heliocentr: Copernicus.

Geocentrism says: Ptolemy.

The main content of heliocentrism:

1.The earth is spherical. If a light source is placed on the top of the ship's mast, people on the shore will see the light gradually decrease until it disappears as the ship moves away from the shore.

2.The Earth is in motion and rotates once every 24 hours. Because the sky is much larger than the earth, it is inconceivable that the infinite heavenly dome is rotating and the earth is not moving.

3.The Sun is motionless, and at the center of the solar system, the Earth and other planets move in a circular motion around the Sun, with only the Moon orbiting the Earth.

The main contents of geocentrism are:

Ptolemy believed that the Earth was stationary at the center of the universe. From the Earth outward, there are the Moon, Mercury, Venus, the Sun, Mars, Jupiter, and Saturn, orbiting the Earth in their own circular orbits. Among them, the movement of the planets is more complex than that of the sun and the moon

The planets move on this wheel, which in turn orbits the earth along the average wheel. Beyond the Sun, Moon, and Planets, there is a celestial sphere stellar sky inlaid with all the stars. Outside, there is the prime mover that moves the celestial bodies.

Geocentrism is the world's first model of a planetary system. Although it is wrong to regard the Earth as the center of the universe, its historical merits should not be erased. Geocentrism's recognition of the "spherical" nature of the Earth and the separation of planets from the stars with an eye toward exploring and revealing the laws of motion of the planets marked a great advance in human understanding of the universe.

The most important achievement of geocentrism was the use of mathematics to calculate the orbit of the planets, and Ptolemy also proposed the concept of "orbit" for the first time, and designed a model of the average wheel of the current cycle. According to this model, people were able to quantitatively calculate the motion of the planets and speculate on the location of the planets, which was a remarkable creation. In a certain period of time, according to this model, the celestial phenomena can be correctly corrected to a certain extent, so it has also played a certain role in production practice.

Ptolemy put forward the geocentric theory.

Bai 1543, Polish astronomical du

On his deathbed, the scholar Nicolaus Copernicus published a work of historical significance, "The Theory of the Movement of the Heavenly Bodies", which completely put forward the theory of "heliocentrism". This system of theories holds that the sun is the center of the planetary system, and that all planets revolve around the sun. The Earth is also a planet that rotates like a spinning top on its top and orbits the Sun like other planets.

"Heliocentrism" was proposed by Copernicus, and Bruno was sentenced to death for spreading "Heliocentrism"! Subsequently, Kepler, Newton, Galileo and other scientists further confirmed the heliocentric theory.

Geocentrism was proposed by Ptolemy.
