“Who is the smartest person in the world?” “Who is the greatest contemporary scientist?” If someone asks you these two questions, I believe many friends will think of Einstein. Yes, the smartest and the greatest can often be tied together, and Einstein undoubtedly has both.
Einstein relied on his incomparable clever advantage and became the greatest scientist of our time. There is a list of scientists in the scientific community, which ranks the great scientists born after mankind entered the era of science and technology, and on this list, Einstein occupies the top spot.
This shows how great Einstein’s contribution in the field of science is. His research and theories have brought mankind into a brand new era. It may be said that Einstein’s great theories are nothing more than the mass-energy equation and the theory of relativity. Are these two theories really that important to mankind?
If you are a science lover, then you can understand how great these two theories are and how important they are to the progress of human science. The mass-energy equation tells us that energy and matter are two manifestations of mass, and there is no essential difference between them. Under certain conditions, energy and matter can be transformed into each other. Under the guidance of this equation, mankind began to study and explore nuclear energy, and achieved good results.
The mass-energy equation reminds mankind of the origin of the universe’s matter, let us understand how the original elements such as hydrogen and helium in the universe came from? At the same time, it has better promoted the formation and perfection of the Big Bang theory.
Not to mention the theory of relativity, its greatness is hard to describe in words. The theory of relativity tells us that the limit of the speed of an object is the speed of light. It also tells us that the universe is distorted. In a sense, the theory of relativity reveals the essence of the universe. As long as we continue to study and explore along the direction guided by the theory of relativity, we hope to truly understand the ultimate mystery of the universe.
The theory of relativity has enabled human beings to achieve rapid development in many fields of cosmology, and his thinking has surpassed that of the people at that time. The special theory of relativity and the general theory of relativity are used to redefine the universe under the state of gravity and high speed. In terms of the basic theory of the universe, no one can surpass Einstein for a long period of time in the future.
There is no doubt about Einstein’s greatness. In addition to studying some theoretical sciences, every great scientist also likes to make some predictions about the future through theory. Such a great scientist as Einstein naturally liked predictions very much. He made a lot of predictions during his life. These predictions were not favored by people at the time. However, in the subsequent scientific exploration, most of them were Confirmed by scientists. Below we will briefly describe three of these prophecies. The first one makes us look forward to it, while the third one makes mankind worry about it.
1. Wormholes. Wormholes are also called space-time holes, or “Einstein-Rosen Bridge”, which is a theoretically existing space-time channel. Its function is to connect the two ends of the distant universe and realize rapid shuttle through it. This speed has exceeded the super-light speed in the traditional sense.
We all know that speed has allowed us to travel all over the world and have a new understanding of the earth. It is also the speed that allows us to walk out of the earth and see the vast universe. As long as we have the advantage of speed, we can go further and explore more cosmic mysteries.
But Einstein used the theory of relativity to tell us that the limit of speed is the speed of light, and mass objects can only approach the speed of light infinitely. The theory that the speed of light cannot be surpassed has been confirmed by scientists. Scientists use particle colliders to accelerate particles. No matter how hard they work, the speed of particles can only be continuously increased on the basis of 99%, and the speed of light cannot reach 100%.
If the limit speed of an object is the speed of light, that is not good news for humans. We must know that the distance of the universe is based on light-years. The diameter of the solar system is two light-years, while the diameter of the Milky Way is 100,000 light-years. At present, the range of the universe that humans can observe is 93 billion light-years. This may be just the tip of the iceberg of the entire universe.
If you want to explore such a vast universe, you can’t do it without a speed advantage, and even if our spacecraft achieves 99% of the speed of light, we can explore the vicinity of the solar system at best, not the entire galaxy, let alone the entire galaxy. The universe is out. If this is the case, then what is the significance of human development of science and technology to explore the universe? Will we be trapped in a limited range forever?
Is the speed of light unbreakable? In fact, Einstein’s general theory of relativity reveals to us that the universe can be distorted, and it can fly faster than light in a distorted space state, and he also proposed a wormhole conjecture.
Wormhole is a channel that may be opened when the universe is greatly distorted. It allows our spacecraft to pass through this hole and quickly reach the other end of the universe. If the wormhole can be realized, then the distance of the universe will no longer be a problem for us. Even two galaxies that are separated by millions of light years can be reached quickly through the wormhole, instead of only fantasy in the past.
2. Cosmological constant. When Einstein proved that the universe is a “steady state”, he added a non-existent factor to the relevant equation. It is the “cosmological constant”. The effect of adding this constant is used to Counteract the gravitational force.
Newton once also proposed a similar “ether theory”, but in later research, Hubble confirmed the correctness of “Hubble’s Law”, thus pointing out that the cosmological constant is wrong and does not exist. Due to the limited scientific and technological strength at the time, and the existence of dark energy was not known, it could not be used to prove that the cosmological constant was real.
In this regard, Einstein also admitted frankly that the cosmological constant was the biggest mistake in his life. So is the cosmological constant really a mistake of Einstein? With the continuous advancement of human science and technology, many people have forgotten Einstein’s prediction. However, after mankind entered the 21st century, in the process of universe research and exploration, both dark matter and dark energy were discovered.
Dark energy is an invisible and intangible force that exists in the universe. It occupies most of the matter in the universe and may be the core and most important thing in the operation of the universe, and dark energy can be offset by gravity. The force generated by dark energy is very similar to the characteristics of the cosmological constant, so some scientists believe that the cosmological constant may really exist, perhaps it is the dark energy we don’t understand now.
3. In the Fourth World War, Einstein made two great contributions to mankind, one is the theory of relativity, and the other is the mass-energy equation. The mass-energy equation reveals that energy and matter are two manifestations of mass and can be transformed into each other.
Inspired by the mass-energy equation, scientists have formally entered the road of nuclear energy research, and since then opened an era of nuclear energy that has made mankind happy and worried. I believe everyone is aware of the power of nuclear energy, especially the emergence of nuclear bombs in the last century, which made mankind aware of this terrible weapon of destruction.
Einstein’s mass-energy equation prompted the birth of nuclear bombs, but for Einstein himself, he was very opposed to war and the use of nuclear weapons. He once made a prediction: “I don’t know what weapons were used in the Third World War, but I know that the weapons used in the Fourth World War are stones.”
This prophecy means that if the third world war breaks out, it will eventually evolve into a nuclear war. Once human science and technology civilization is destroyed, the surviving people will live on a nuclear-radiated earth, enter the era of doomsday, and lead primitive civilization. life.
After the earth recovers, human science and technology no longer exist. Human civilization regresses to primitive civilization, and when war again occurs, it can only fight with weapons such as stones. This prediction may seem a bit pessimistic, making people feel scared, and some people think it is impossible to achieve.
But if we think about it carefully, you will find that Einstein did not make this prophecy when his head was heated, but that prophecy came after a lot of thinking and analysis. The rapid development of mankind has brought people better and better living conditions, but everything has two sides, and technology also makes weapons more powerful.
The 5,000-year history of human civilization is actually a history of war. From ancient times to the present, wars of all sizes have never really stopped. Even now in the relatively peaceful era, conflicts and small-scale wars have never disappeared, and they are still taking place in some areas.
The power of weapons is getting stronger and stronger, and in the future humans may compete for resources more and more fiercely. When the contradiction rises to a certain level, it is not impossible for a new world war to break out. The power of powerful weapons, coupled with nuclear weapons, is enough to cause the restart of human civilization, so such predictions make people worry.
Einstein is such a great scientist, every one of his predictions is not random. In addition, most of his predictions have been fulfilled, and those that have not yet been fulfilled are not going to happen, and because human technology has not yet advanced to a higher stage, there is no way to verify the scientific theories described in the predictions. . Therefore, we should pay attention to Einstein’s third prediction. Only by maintaining peace can mankind have a future. Otherwise, once civilization is restarted, all our efforts will be in vain.
