For Einstein, I believe that friends will not bear weight, and he can be called the greatest scientist in the history of human science. Once the scientific community has ranked all the great scientists of mankind for hundreds of years, Einstein has been ranked as the top leader. It can be seen that in the scientific community, people recognize Einstein’s great contribution to human science. No one can surpass the contribution so far.
So what is Einstein’s great contribution? I believe that when many people mention Einstein, they will think of the great theory of relativity it put forward. Yes, the theory of relativity can be said to be the greatest achievement in Einstein’s life, and it is also the greatest achievement in the current history of human science. In a sense, the theory of relativity actually hints to us part of the ultimate mystery of the universe.
If we can turn some of the theories put forward by the theory of relativity into reality, then human beings dare not say that they will become the overlord of the universe, but there is no problem with the Milky Way. In addition to the theory of relativity, Einstein also put forward the mass-energy equation, which suggested to mankind for the first time the relationship between matter and energy, and mankind’s most powerful ultimate weapon nuclear bomb was researched on this theoretical basis.
We all know that every great scientist has a special hobby, which is to make predictions about the future. Einstein naturally has such a hobby, but Einstein’s prediction is very different from the predictions of other scientists. The predictions of other scientists, ten predictions can be achieved in half in the future, that would be the best, and Einstein’s prediction success rate is very high, so high that scientists feel incredible.
Einstein’s predictions are not complete nonsense, but some predictions based on his own scientific theories. These predictions seemed like fantasy at the time, but today, 100 years later, we continue to use advanced science and technology to confirm them. With these prophecies. Of Einstein’s five major predictions, three have been successfully fulfilled, and two have not been fulfilled, and one of them is very worrying.
In fact, Einstein’s predictions are far more than five, and those 100 years later have all been fulfilled. If there are ten Einstein’s predictions, then eight of them have been scientifically proven, and only two have not yet Realize, and these two, in the eyes of scientists, have a high probability of being realized in the future. If this is the case, then the success rate of Einstein’s prediction is 100%. Does it make us feel incredible? So, what is fulfilled in Einstein’s prophecy? Let’s take a brief look at it below.
1. The prediction of the equivalence of mass and energy, I believe that friends all know the famous mass-energy equation, E=MC, through a formula that tells us that mass and energy are equivalent. Mass can be transformed into energy, and the same energy can also be transformed into mass. Such a conclusion was shocking 100 years ago. Few people would believe such prophecies at the time.
You know, if the mass and energy are equal, it means that the energy value obtained by burning one kilogram of oil should be converted into one kilogram of oil with this same energy value. But in real life, I believe everyone knows that it is very simple to convert oil into energy through combustion, but if you want to convert the same energy after conversion into oil, I believe it is not yet visible.
It is precisely because people cannot see the fact that energy is transformed into matter, that people doubt the prediction of the equivalence of mass and energy. However, with the advancement of human science and technology, scientists have finally confirmed through continuous research that energy and mass are equal, and they can be transformed into each other. The reason why we can’t convert energy into matter is because energy transformation matter still needs to meet many conditions.
And this kind of condition is also very difficult to see in the universe. Perhaps only the moment of the Big Bang met the conditions for energy to be transformed into matter, so there is a scenario where energy is transformed into matter after the Singularity Big Bang. In fact, in supernova explosions in the universe, there are also some conditions for energy to be converted into matter. One of the important conditions is that energy must be released in an instant. Only by doing this can it be possible to convert energy into matter.
2. The prediction of black holes. I believe everyone knows about black holes. Last year, scientists published the first photo of a black hole in mankind, officially proclaiming that the black hole is real. Black holes have always been the product of conjecture in the past. They are actually prophecies under Einstein’s theory of relativity. According to the theory of relativity and Einstein’s conjecture, there may be a special powerful celestial body in the universe, which is a black hole.
After the black hole was proposed, it was naturally questioned by many people. However, after nearly a hundred years of continuous exploration and research, scientists have observed a lot of accretion disk phenomena caused by supermassive black holes in the universe. For example, the center of the Milky Way galaxy is unusually bright. There may be a supermassive black hole. Its powerful gravitational pulls the surrounding stars constantly approaching it, so the distribution of stars in the center of the Milky Way is very dense.
It is precisely because there are so many and very dense stars around the galactic center that it can make the galactic center appear extremely bright, even if it is 26,000 years away from the earth, it is still a very dazzling existence. Although scientists have now confirmed the existence of black holes, what exactly are black holes? What’s inside it? Where is the matter that was swallowed by it? It is still a mystery.
Since black holes have to swallow even light, small and medium-mass black holes have no obvious accretion disks, so it is difficult for us to observe them. And those supermassive black holes are basically the centers of large galaxies like the Milky Way, which are too far away from the earth, and it is impossible for humans to conduct actual surveys with current technology. Therefore, it may take a long time to explore the true mystery of black holes.
3. The prediction of the introductory lens. The theory of relativity tells us that the universe is not a flat space, but a space that can be distorted. Therefore, on this basis, Einstein proposed the gravitational lensing effect, which is a manifestation of mass-curved space-time, and light can also bend in such a warped space-time.
Using the gravitational lensing effect, we can observe many celestial bodies hidden in the past, and the gravitational lensing effect has been confirmed by scientists, and related telescopes have also been studied. Of course, our current understanding and research on gravitational lensing is still relatively small, and it is believed that in the near future, the gravitational lensing effect will bring greater surprises to mankind.
4. The prediction of the constant speed of light, I believe many friends know that Einstein’s theory of relativity tells us that the speed of a mass object can only be infinitely close to the speed of light, and even massless particles like photons can only reach the speed of light. This is the limit theory of the speed of light. This prediction has been confirmed by scientists. Through the particle collider, we can only speed up the particles to 99.999%. No matter how powerful the collider, we can only continue this 9 without achieving the speed of 100 light.
V. Prediction of gravitational waves: It is relatively easy to understand gravitational waves from the mass-curved space-time in general relativity. When an object with mass accelerates, or when its mass changes, it will have a ripple effect on space and time, and this ripple will travel outward at the speed of light. On February 11, 2016, the LIGO and VIRGO teams jointly announced that humans first directly detected gravitational waves on September 14, 2015, which originated from the merger of two black holes.
The above are the five representative prophecies that Einstein has fulfilled. So what are the two unfulfilled prophecies? One of them is the wormhole that we often see in science fiction works. The concept of “space crossing (wormhole)” was first proposed by the physicist Ludwig Frahm in 1916, and this theory is Ein Stan and Nathan Rosen made perfect assumptions when they discussed the “gravitational field” in 1935, so the wormhole is also called the “Einstein-Rosen Bridge”.
Einstein proposed in the general theory of relativity that three-dimensional space can be bent, so when there is a massive celestial body in the universe due to the action of gravity, the space around the celestial body will be distorted, just like a steel ball is placed on a sponge same.
Therefore, Einstein believed according to the general theory of relativity that since space can be bent and deformed, assuming that there are two points A and B in the universe and the two points are far apart, can the space where the two points AB be deformed and deformed, so that Are these two points AB getting closer?
Theoretically speaking, this kind of channel that can connect two space-time points exists, but it is not so easy for us to find such space-time wormholes in reality. At least the taller man-made wormholes are farther away for humans. Although the wormhole predicted by Einstein has not yet been discovered by us, scientists believe that its probability exists.
It’s just that human beings are still relatively weak in science and technology, and their understanding and understanding of space-time distortions are still very weak, so we can’t observe the possible wormholes in the universe. The existence of wormholes also directly determines whether humanity’s dream of vertical and horizontal universe can be realized.
Another unfulfilled prophecy is the doomsday prophecy. When you talk about the doomsday prophecy, many people will think of the 2012 Mayan prophecy. Thousands of years ago, the glorious Maya civilization predicted that the earth will usher in a doomsday in 2012, but it will be 2012. In 2016, the earth was still so stable and nothing happened.
Although the doomsday prophecies that worries people have not been fulfilled, there are not many doomsday prophecies. Hawking also predicted that the earth will usher in the end in hundreds of years, and Einstein once also predicted the end of mankind.
Einstein’s doomsday prophecy does not refer to the dramatic changes in the ecological environment, but to the worries about human doomsday wars. I believe my friends all know that the history of human civilization can also be called a history of war. From ancient times to the present, the interior of human civilization I don’t know how many wars have occurred. Even in the modern era of peace, the war never ceases.
Like war may be a human nature, and this nature may bring destruction to human civilization in the future. No matter how large the scale of human wars in the past, it was difficult to bring devastating blows to the ecology of the earth, but since the advent of nuclear weapons, the situation has been completely different.
Einstein predicted: Although I don’t know what weapons humans will use in the Fourth World War, we know that in the Fifth World War, the weapons used by humans will be stone tools and wooden sticks. Einstein’s words actually tell us that if a world war breaks out again, there is a high probability that nuclear war will eventually be destroyed, human science and technology civilization will disappear completely, and the people who survive will enter the primitive age and civilization will start again.
This last prophecy worries many people. People are worried because we all understand the inferiority of human beings. Whether in the earth age or in the future human beings enter the space age, it is impossible to eliminate problems such as resource contention and internal conflicts. Once conflicts are stimulated to a certain extent, wars will break out. Therefore, although we do not expect them to happen in World War IV and World War V, some things are difficult to do as we wish.
