When we stand on the blue earth and look up at the starry sky, it seems that all the stars are still. However, this is only a visual illusion, in fact, the Earth is carrying us through the universe at an astonishing speed.
Every second, the Earth takes us 630 kilometers, which means that we travel more than 50 million kilometers in the universe every day. Moving so fast, but not noticing, makes one wonder: what is driving the earth so wildly? Where does it lead us in the universe?
Before answering this question, we need to realize that in the vastness of the universe, no object is truly stationary. This was one of the few mistakes Einstein made during his lifetime, he once thought that the universe was static, but the truth of the real universe was far more complex than he thought. Every celestial body in the universe is constantly moving, and they either rotate around their own axis or around other celestial bodies, forming one complex cosmic structure after another.
The Sun's Lead: The Source of Earth's Speed
The Earth's ability to travel at 630 kilometers per second in the universe is powered by the Sun, the central star of our solar system. The Sun is a medium-sized yellow dwarf star that has a strong gravitational pull and radiation that firmly controls all the planets in the solar system, including the Earth.
The mass of the Sun accounts for 99.86% of the total mass of the solar system, making it the undisputed ruler of the solar system. Planets such as the Earth move around the Sun in an elliptical orbit under the gravitational pull of the Sun, and the special shape of this orbit causes the distance between the Earth and the Sun to constantly change during its revolution. It is this combination of gravity and orbit that gives the Earth a sustained forward speed.
If we zoom in and look at the solar system as a whole, the sun is not stationary. The Sun also moves in the Milky Way, taking all the members of the Milky Way with it at a speed of about 220 kilometers per second, orbiting around the center of the Milky Way, a supermassive black hole. This black hole has a mass equivalent to millions of times the mass of the Sun, and its powerful gravitational field is the root cause of the movement of the entire solar system.
In this way, the mystery of the Earth's speed lies not only in its own rotation, but also in the vast and complex structure of the universe in which it is located. From the sun to the solar system to the vast Milky Way, every level is contributing to the speed of the Earth.
A Journey to the Solar System: A Dance Around the Milky Way
Guided by the sun, the earth embarks on a journey around the sun at a speed of 630 kilometers per second. This speed allows the earth to complete one revolution in one year, which is known as a year. However, the sun itself is not stationary. The Sun, carrying planets such as the Earth, orbits a huge black hole at the center of the Milky Way at a speed of about 220 kilometers per second. This huge black hole, millions of times the mass of the Sun, is its strong gravitational pull that pulls all the celestial bodies in the solar system.
The orbital period of the solar system around the center of the Milky Way is 225 million years. This means that in the history of the solar system, it has made about 20 revolutions around the center of the Milky Way. With each revolution, the solar system experiences a strong gravitational field at the center of the Milky Way, which may be related to periodic mass extinction events on Earth. Scientists have found that the time interval between mass extinctions on Earth seems to be mysteriously linked to the sun's orbital cycle.
When we zoom out again, the galaxy itself is in motion. As a member of the local group of galaxies, it orbits around a mysterious point of power in the universe along with other large galaxies. This point of power may not exist in our current model of the universe, it may be some kind of supermassive object, or it may be a gravitational center formed by multiple large galaxies. The orbital period of the Milky Way is estimated to be 100 billion years, a time span that is almost unimaginable for humans.
In this way, every journey that the Earth has undergone is part of the structure of the universe on a larger scale. From the Earth to the Sun, to the Solar System, to the Milky Way, each level plays a unique role in the universe, weaving together a magnificent picture of the universe.
The Mystery of the Rotation of the Universe: The Traction of an Unknown Force
In the process of exploring the depths of the universe, we have discovered that neither the Earth, nor the Sun nor the Milky Way exist in isolation. Every celestial body is in constant motion, and every galaxy is revolving around a larger cosmic structure. This rotation is not chaotic, but has some underlying order and regularity.
As a member of the local group of galaxies, the Milky Way orbits for 100 billion years, which is almost eternal relative to the age of the universe. This makes us wonder what the universe will look like when the Milky Way completes one revolution. Could it be that there is some kind of periodic change like the black hole in the solar system around the center of the Milky Way, which guides the life and death of the universe?
Scientists are currently unable to answer this question precisely because our knowledge of the universe is still limited. But we know that every movement in the universe has a cause, and every rotation has a meaning. Whether it is the rotation of the Earth around the Sun or the rotation of the Milky Way around the center of the universe, it is driven by some mysterious force or something. These forces may be gravity as we already know it, or it may be some cosmic force that has not yet been discovered.
With the progress of science and technology and the in-depth exploration of the universe by human beings, we have reason to believe that one day in the future, these mysterious forces that drive the rotation of the universe will be revealed by human beings. Until then, let us remain curious and in awe of the universe, continue to move forward on the road of science, and explore those unknown mysteries.
Exploring and Pondering: The Mystery of the Rotation of the Universe
In this magnificent journey through the universe, we have seen how the earth is orbiting and rotating again and again under the guidance of the sun at a speed of 630 kilometers per second. We also learned how the solar system as a whole orbits the black hole at the center of the Milky Way and goes through a 225-million-year orbital cycle at a speed of 220 kilometers per second. On a more macro scale, the Milky Way is also in the local group of galaxies, and along with other large galaxies, it orbits around a mysterious point of power for 100 billion years.
Every revolution and rotation is the result of the gravitational pull between the celestial bodies in the universe. These gravitational forces may be familiar with gravitational forces, or they may involve more complex and esoteric cosmological theories. It is the combination of these gravitational forces that shapes the structure of the universe as we see it, driving every celestial body in the universe to constantly shuttle and rotate in time and space.
Although we have been able to explain some phenomena of celestial motion, there are still many unknowns in the universe waiting to be explored. What forces drive the rotation of the universe? What will be the end of the universe? In the infinite expansion of the universe, where will our home planet end up? These are these questions, and perhaps one day in the future, humanity will find the answers. But until then, let us continue to maintain our love and curiosity about the universe, keep chasing those unknown mysterious powers, and explore the ultimate mystery of the universe's rotation.
