From a philosophical point of view, matter is the unity of absolute motion and relative rest, and all things in the world are in motion and change. This view is equally valid when placed in the context of the entire universe.
Long ago, humans always thought that the sun and the moon revolved around the earth and that the earth was a stationary individual. But when modern science gradually developed, we realized that the Earth has also been in a state of motion.
Motion of the Earth
The Earth moves in two ways, rotation and rotation.
After astronomers' research found that the so-called sunrise and moonset, not the sun is rotating, but rather the Earth rotates around the sun, and there are many celestial bodies that rotate around the sun like the Earth, in addition to the other seven planets, the expelled Pluto also still has a trajectory around the sun.
The explanation for this phenomenon stems mainly from Newton's law of gravitation. Newton believed that the greater the mass of an object, the greater its gravitational force. As the only star in our solar system, the Sun's mass is absolutely dominant over the planets in our solar system, so the other planets are subject to the Sun's gravitational force and move in orbit around it.
Although we live on Earth and cannot visually see the trajectory of the Earth, the average speed of the Earth's rotation can reach 29.8km/s when viewed from the perspective of space.
In addition to its rotation, the Earth is also making a rotational movement. There are various theories about the reason for the Earth's rotation. Some believe that the Earth got its starting speed from the collision of stars in space, while others believe that the Earth has been carrying its own speed since its birth. Either way, it is clear that the Earth is not in a static state.
The change of day and night and the alternation of the seasons are the passage of time that we can feel from the level of the Earth, and another way of presenting the movement made by the Earth in the universe.
If the Earth, which is orbited by the Moon, moves, does the Sun also move? Will the Milky Way galaxy? In fact, the answer to all of these is yes.
Solar System and Milky Way
The Sun is only one of the hundreds of billions of stars in our galaxy, and although the Milky Way is not a celestial body, it does allow the Sun to make a turnover motion around its silver center.
Scientists calculate that the Sun is about 2.4-2.7 play light years away from the Galactic center, and that it takes about 250 million years to move around the silver center at a speed of 220 kilometers per second for one week. In this way, when the Sun is moving around the silver center, the Earth is also displaced at some level by the Sun's gravity.
So how is it that the galaxy can keep the sun moving around its center?
In the Milky Way galaxy, in addition to young stars like the Sun, there are many older stars that have come together to form the silver core we see about 20,000 light years in diameter. However, there comes a time when a star dies, and when they do, the interior collapses rapidly, resulting in the formation of a black hole. A black hole is a dense object with a gravitational pull so strong that it can absorb all matter that comes near it.
Therefore, scientists believe that there is a supermassive black hole in the center of the galaxy, and the Sun is influenced by this black hole to move around the silver center.
But it is curious that the whole galaxy is also in motion. According to conventional understanding, the motion of celestial bodies comes from higher masses, but there are hundreds of billions of stars in the Milky Way. What is it that can make the Milky Way, which is already so massive, have to move closer to it?
And, as observed by scientists, because of the movement of the Milky Way, the Earth also followed with the speed of 630 kilometers per second in the universe, where the Earth and the Milky Way are actually going?
The presence of a giant citation source
We often say that there are people outside of people. In the universe, the same applies, beyond the Milky Way is the Virgo Cluster, which is part of the Lani Kaiya Supercluster.
Since there is a relationship of inclusion, it seems not surprising that a greater gravitational force appears. In the 1980s, scientists discovered an amazing phenomenon in the direction of the constellations Perseus and Centaurus: there, they observed a large number of aged galaxies and galaxies colliding with each other, thus also radiating a large number of radio waves.
Serpens and Centaurus, like Virgo, are part of the Lani Kaiya Supercluster, and their distribution shows that all galaxies are not close together. Here, however, there are galaxies close together or even colliding, and scientists have studied them.
The study found that there is a large gravitational field, it is different from the black hole that can swallow matter, but with their own great gravitational force makes the galaxies, including the Milky Way, hundreds of millions of light-years away towards it, and this site is named by scientists "giant gravitational source".
Scientists speculate that the giant gravitational source is part of the Momentum Cluster, about 250 million light-years away from the galaxy, and its mass is 3-5.4×10^16 times that of the Sun. The super size and the super gravitational force make many galaxies affected by it.
Although further study of the giant gravitational source is not possible due to its location from Earth just because of the occultation zone on the galactic disk. However, by means of redshift, scientists have found that the Milky Way is moving toward the Virgo Cluster, which in turn is moving toward Centaurus, where the giant gravity source is located. Moreover, the speed of this motion is not low, and it is estimated that all galaxies and their intra-galactic objects affected by the giant gravity source are moving in that direction at a speed of 600-700 kilometers per second.
And the Earth is moving towards the giant gravitational source at a speed of about 630 km per second.
Although from the perspective of the Earth alone, it is speeding to another location in the universe, as a whole, the entire space environment in which the Earth is located is moving, and such synchronized motion instead leaves the Earth in a relatively static state.
What exactly will happen when the galaxy reaches Centaurus is still too far away for us. Before that happens, the first thing we need to figure out is how exactly the giant gravitational source is formed.
