The Earth is carrying mankind through the universe?

Modern science believes that our Earth was born 13.8 billion years ago, there was a singularity explosion, the singularity is an infinite mass, infinite energy, infinite heat, infinite density, and infinitely small volume of the point, after the explosion of this point, the rapid expansion of the universe around, after 13.8 billion years, the universe has expanded into what we see now, now we know In the universe, there are many celestial bodies, like stars, planets, comets, asteroids, neutron stars, etc. These are produced after the Big Bang, and our Earth is a planet in the solar system, there are a total of eight planets in the solar system, they are Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune.

Outside of Neptune, there is also a Pluto, once Pluto also belongs to a planet, but later scientists think that Pluto's volume and mass are too small, so Pluto was kicked out of the ranks of the planets, now the solar system is left with only eight planets, in the eight planets, the current after the planet Earth was born life, the emergence of life to the planet Earth added a lot of colors, especially human After the emergence of human beings, many mysteries of the Earth were solved. According to the research of scientists, we can know that the Earth is constantly rotating and rotating every moment, and the time of one rotation is about 24 hours, and the time of one rotation is about one year.

In the solar system, the mass of the Sun accounts for 99.86% of the total mass of the solar system, and the remaining eight planets and other substances account for 0.14% of the total mass of the solar system, from the percentage we can know that the Sun's mass is very large, according to Newton's law of gravity, any material with mass is gravitational, the greater the mass of the material, the greater its gravitational force, in the solar system. As the mass of the sun is the largest, so the gravitational force of the sun is also the largest, strong gravity can attract all eight planets, and the eight planets in order not to be swallowed by the sun, can only choose to rotate and rotate, rotation and rotation can produce centrifugal force, centrifugal force and gravitational force balance each other, so the eight planets can be stable rotation around the sun.

In the universe, not only the eight planets are rotating around the sun, but the sun is also rotating around the larger galaxy, so we can say that the entire universe is in constant motion. The sun is constantly rotating around the center of the galaxy, the speed of rotation is about 220 kilometers per second, which is equivalent to the sun carrying the earth in the universe, and the earth carrying us in the universe, the earth, in the end, to take us to where?

Scientists found through research that in the center of the Milky Way, there is a supermassive black hole, the gravity of this black hole is very strong, the entire galaxy is rotating around these black holes, the current diameter of the Milky Way reaches 200,000 light years, but for the universe, 200,000 light years is not a very long distance, you know, humans can now observe the diameter of the universe is about 93 billion light years, and This is not the full extent of the universe, the universe may be larger than we think, how big is the universe? Scientists are also actively researching, scientists have found that there is a mysterious object hidden near the Milky Way, and the gravitational force of this object is very strong.

Several surrounding galaxies are rotating around this mysterious object, this mysterious object in the end what is it? To solve this answer, scientists have also made a lot of efforts, in 1986, scientists in this supergalaxy cluster found a huge gravitational center, this gravitational center is about 250 million light-years away from the Milky Way, and its scale reached 400 million light-years, the mass is 5 * 10^16 times the Sun, we can hardly imagine this mass in the end how big, scientists will be this huge gravitational center Scientists call this huge gravitational center is a giant gravitational source, scientists believe that several galaxies around this giant gravitational source are rotating around it, our galaxy is also rotating around it, scientists have calculated that the speed of the rotation of the Milky Way is about 600 kilometers per second. This means that the Milky Way travels 52 million kilometers through the universe in a day.

And our Earth follows the Milky Way in the universe, the distance a day is also 52 million kilometers, scientists still do not know what kind of celestial body this huge gravitational center is, but many scientists believe that this huge gravitational center may be a huge black hole, and some scientists believe that this huge gravitational center is a singularity, the singularity is an infinite mass, infinite energy, infinite The singularity is a point of infinite mass, infinite energy, infinite heat, infinite density, an infinitely small volume of the point, this point after the explosion, the universe is rapidly expanding in all directions, although scientists have not found the singularity, this huge gravitational center, and the singularity is very similar. In the future, with the progress of human technology, maybe we can solve this mystery.

See there may be many friends who will have a question, is why the Earth in the universe moving so fast, but we can not feel it? This is related to the reference, according to Einstein's theory we can know that any material is in relative motion when we see the car moving forward because we take the stationary material as a reference, so we can see the car in the fast forward, and we do not feel the Earth is turning, because we can not find a suitable reference, so we can not see the Earth in motion. If we can stand outside the earth and find a suitable reference in the universe, then we can also feel the earth is rotating.

Why are all the celestial bodies in the universe in regular motion? In addition to these reasons, there are many other reasons that we do not know, the universe is vast and mysterious, and there are many mysteries hidden in the universe that we do not know, but I think that humans are the most intelligent life on earth, human technology is constantly progressing, in the future, with the development of human technology, we will be able to Solve the mysteries of the universe
