Now we know that the earth is a planet in the solar system. There are eight planets in the solar system, namely Mercury, Venus, Earth, Mars , Jupiter , Saturn , Uranus and Neptune . There is also an Pluto outside Neptune. Pluto was once a planet in the solar system, but later scientists believed that Pluto was too small, so they kicked Pluto out of the ranks of planets. Among the eight planets in the solar system, only the planet Earth gave birth to life. The emergence of life has added a lot of color to the earth, especially after the appearance of humans, it has unraveled many mysteries on Earth. However, so far, there are still many physical problems that humans cannot explain.
The first physical problem that humans cannot explain - how the universe was born
Modern science believes that our universe was born 13.8 billion years ago. 13.8 billion years ago, an singularity exploded. The singularity is a point with infinite mass, infinite energy, infinite density, infinite heat, and infinite volume. After this point exploded, the universe quickly expanded to the surroundings. After 13.8 billion years, the universe expanded to what we see now. The celestial bodies in the universe were born after the Big Bang. Although many scientists now believe that the universe was born in the Big Bang, there are still many loopholes in the Big Bang , such as how the singularity before the Big Bang was born? Logically speaking, there should be no infinitely small or infinitely large matter in the universe.
However, because the singularity is too mysterious, scientists can only describe it as singularity. At present, scientists are also actively exploring the mysteries of the universe. With the development of human science and technology in the future, maybe we can unlock the mysteries of the universe.
The second physical problem that humans cannot explain - do wormholes really exist?
Once Einstein used formulas to calculate the existence of black holes, but due to the limited technology of humans at that time, many people did not believe in the existence of black holes. Later, with the advancement of human technology, in 2019, scientists finally took the first photo of a black hole, which also proved that black holes do exist in the universe. In addition to black holes, Einstein also predicted wormholes, gravitational waves, etc. At present, gravitational waves have been discovered by scientists, and there are still wormholes that have not been found by scientists. Scientists believe that wormholes are a tunnel that can travel through time and space. If we can enter wormholes, then we can travel from one side to the other side.
Many scientists believe that black holes may be the entrance to wormholes. The characteristic of black holes is to constantly swallow matter. There may be a more mysterious substance on the other side of the black hole. White hole . The black hole and white hole are connected together to form a wormhole. Although humans have not found wormholes yet, with the advancement of human technology in the future, we may be able to find wormholes.
The third physical problem that humans cannot explain - dark matter
There are many scientists who speculate that there is a large amount of dark matter in the universe, and scientists believe that dark matter is the most important matter in the universe. The matter that can be seen in the universe (stars, planets, comet , asteroids, etc.) accounts for 5% of the total mass of the universe. Invisible matter (dark matter) accounts for 95% of the total mass of the universe. From the proportion, we can see that dark matter is the most important matter in the universe. Scientists believe that dark matter can promote the continuous expansion of the universe and control the movement of celestial bodies. In the early 20th century, American physicist Edwin. Hubble discovered when observing the Andromeda galaxy that the spectrum in the galaxy showed a redshift phenomenon. This phenomenon means that these galaxies are far away from us.
After seeing this phenomenon, Edwin Hubble proposed a bold guess, that is, our universe is still expanding. Later, scientists observed the universe one after another and finally found that Edwin Hubble's theory is correct. In addition, dark matter can also control the movement of celestial bodies, because when scientists observed the Milky Way, they found that celestial bodies at the edge of the Milky Way were rotating regularly. We know that there is a supermassive black hole in the center of the Milky Way.
This black hole has very strong gravitational force, but generally speaking, the closer the celestial bodies near the black hole, the greater the gravitational influence it will be. The farther away from the celestial bodies near the black hole, the less the gravitational influence it will be. The celestial bodies at the edge of the Milky Way are very small with the gravitational force, but they rotate very quickly. We all know that matter will produce centrifugal force when it moves. The faster the rotation speed, the greater the centrifugal force. If we say that, celestial bodies at the edge of the Milky Way should be thrown out by centrifugal force, but not only are the celestial bodies at the edge of the Milky Way not only are not thrown out by centrifugal force, but can rotate stably around the center of the Milky Way. Therefore, scientists guess that this may be related to dark matter.
The fourth unexplained physical problem - what is the principle of quantum entanglement
Quantum entanglement refers to two paired particles, no matter how far apart they are, as long as we affect one of the particles, the other particle can also be affected, and the speed of this influence is almost instantly complete. For example, we place one particle in the southmost part of the universe and the other particle in the universe In the northmost part of the world, as long as we influence one of the particles, the other particle at the edge of the universe will also be affected. For this reason, scientists also conducted a special experiment. Scientists placed the two paired particles more than 100 kilometers apart, and then paired the paired third photon with one of the particles. Finally, the scientists found that a third photon appeared on the second particle more than 100 kilometers, which shows that quantum entanglement can indeed affect the other party instantly. But until now, scientists do not understand what the principle of quantum entanglement is?
The fifth unexplainable physical problem - the amount of positive and antimatter is not equal
Positive matter and Antimatter were proposed by scientists in 1927. At that time, physicist Paul Dirac accidentally discovered negative energy in the equation, and then he proposed antimatter. He believed that any matter has two positive and negative aspects. When positive and antimatter meet, an annihilation reaction will occur, and at the same time it will generate huge energy. If we look at this theory, then after the birth of the universe, the number of positive and antimatter should be the same. However, what surprised scientists was that we can see positive matter everywhere in the universe, but we cannot find antimatter. Why is this? Some scientists believe that these antimatters may be controlled by some mysterious force.
If all antimatter is released, then positive matter and antimatter will annihilate each other, which will lead to the disappearance of the world, so antimatter is likely to be hidden. At present, scientists can create antimatter in the laboratory, but the antimatter created by humans is much worse than everything in the universe. With the advancement of human technology in the future, maybe we can find antimatter in the universe.
The universe is vast and mysterious, and there are many mysteries we don’t know in the universe. Since its birth, human beings have been constantly exploring the mysteries of the universe. After so many years, scientists have finally gained a certain understanding of the universe. However, human beings are limited in technology and cannot unravel all mysteries in the universe. However, human beings are the wisest life on earth. In the future, with the development of human technology, we will definitely be able to unravel all mysteries in the universe. The editor hopes that this day will come soon. Do you have anything to say about this?
