Humans evolved from land creatures, but humans The biggest difference between humans and other creatures is that wisdom was born. Relying on wisdom, humans have reached the top of the Earth’s food chain in just a few thousand years. Humans have been able to leave the Earth and explore the universe. This shows the speed of the development of human science and technology. It is very fast. Although human science and technology are developing very fast, there are still many problems in the universe that we cannot explain. For example, what is time? Time may be the first cycle that humans feel from nature. When the sun rises, it brings day, and when it sets, humans usher in night.
The Elusiveness of Time
Time is a common property that all of us, especially physicists, fail to grasp its essence. But why is time so elusive? Astrid Eichhorn, a theoretical physicist at the University of Southern Denmark, said: If we can answer this question well, then it is not a problem. From a certain perspective, time is simple: because there are with it, things will not happen simultaneously. It may be easy to say, but at least everyone can reach a consensus. From this point of view, the existence of time can be explained as a prerequisite for some universe. In this, some things cause other things to happen. Many physical theories, from Newton’s laws of motion to quantum mechanics, avoid this problem. In these theories, time is an independent variable; other things will change, but everything can change. Time cannot be changed.
Time as an Independent Metronome
Time exists independently of physics, like a separate metronome, governing the gradual unfolding of everything in the universe. The once-famous scientist Aristotle believed that if time has a beginning, it must have a “first moment” to start counting. This first moment needs to be in an earlier or later time period. Since there is an earlier time than the first moment, the first moment is no longer the first moment, which means there must be an earlier time than it. If we look at it according to this theory, time has no beginning or end. In fact, different people have different understandings of time. Identical. The famous physicist Newton was also very interested in time and proposed his theory. Newton recognized Aristotle’s understanding of time.
Newton’s Concept of Absolute Time
But Newton believed that time is a real-time that flows no matter what. In his book, “Mathematical Principles of Natural Philosophy,” Newton argued that there is absolute time, in addition to the relative time proposed by Aristotle. He believed that absolute time is independent and separate from the relative time. Things change extremely and will pass even if they do not change in motion. Newton’s view of time is different from Aristotle’s concept of time. Aristotle believed that if there is no movement, time does not exist. Newton held the belief that time is a consistent entity that flows uniformly. Whether the world is moving or not, absolute time always exists.
Einstein’s Relativity and Time Dilation
His concept has been influential for centuries. People worldwide have recognized this concept of time through education, making it a widely accepted way to understand the passage of time. Newton used this as a model to establish modern physical theories, which are effective and self-consistent in most cases. But is time really such a thing? Newton’s three laws of motion, renowned in modern science, do not provide any information about the direction of time. Additionally, the physical laws proposed by Newton are not time-dependent. This also means that Newton’s explanation of the time may not be the final truth.
Einstein’s Theory of Relativity and the Flexibility of Time
So what exactly is time? Later, after Einstein appeared, there was a different definition of time. Einstein challenged the concept of time as an absolutely solid entity. In his theory of relativity, time became something malleable. The observer and the gravitational field affect the cat in the box.
Einstein believed that time would become different depending on the observer’s location. The same thing may happen to different observers or even simultaneously in different orders. Time and space are closely intertwined. Together, they form the four-dimensional structure of space-time. Einstein’s theory of relativity proves that time is relative. If an object moves fast, the speed of time will be slower. To understand this phenomenon in the universe, it is gravitational time dilation. According to Einstein, the speed of speed can affect the passage of time.
Time as Subjective and Objective
But, the faster the speed, the slower the passage of time. When it is infinitely close to the speed of light, time will tend to stop. Time dilation in the theory of chivalrous relativity is proposed based on an important premise: that the speed of light remains unchanged.
The constant speed of light does not mean that “the speed of light in a vacuum is constant at 300,000 kilometers per second.” It means that the speed of light remains constant in any frame of reference. For example, even if you travel by 99%, A spaceship is flying at the speed of light. When I am on Earth, I see that the speed of light emitted by you is still the speed of light, not 199% of the speed of light. For example, for a pair of twin brothers, the older brother drives the spaceship to fly away from the Earth at sub-light speed, and the younger brother is flying at sub-light speed. On Earth, who is losing time more slowly, the elder brother or the younger brother? Since speed is relative to the elder brother, the younger brother also flies at high speed. In the eyes of the older brother, the younger brother’s time has also slowed down. Could it be said that time has slowed down for both people? Isn’t this contradictory? The elder and younger brother’s thinking that time is slowing down for each other is not contradictory. This is because they rotate in different reference systems and use themselves as the reference point. When the reference systems are different, comparing the speed of time passage doesn’t make sense anymore.
The Mandela Effect: A Subjective View of Time
Scientists also conducted special experiments to prove that Einstein’s theory was correct. In 1971, scientists used high-precision atomic clocks to verify the slow clock effect in the theory of relativity. Scientists placed four atomic clocks on two aircraft and placed one atomic clock on the ground as a reference. The reason why scientists rotated the atomic clock is that it is very accurate. The error will be less than one second within tens of millions of years. The two planes fly east and west, respectively. When a plane flies eastward, it moves in the same direction as the Earth’s rotation. This means that its speed relative to the ground is the sum of its speed and the speed of the Earth’s rotation.
On the other hand, when a plane flies westward, it moves against the direction of the Earth’s rotation. In this case, the speed relative to the ground is obtained by subtracting the speed of the Earth’s rotation from the plane’s speed. The final experiment proved that the atomic clock on an eastward-flying aircraft is 59 nanoseconds slower than the ground atomic clock. The atomic clock is 273 nanoseconds ahead of the ground atomic clock. The data calculated through the relativistic clock slow effect theory is consistent with the results of scientists’ experiments. This experiment proves that Einstein’s view of time is correct.
Time as a Subjective Illusion
Gravity can also affect the passage of time. When the spacecraft travels near a black hole, the passage of time on the spacecraft will become slower and slower. Through Einstein’s general theory of relativity, we can know that the essence of gravity is actually the bending of time. The moon rotates around the Earth because the Earth bends the surrounding space and time, causing the moon to move in a specific path. Therefore, the gravitational field also affects light, causing time to dilate. In other words, time will slow down around a black hole, so time around a gravitational field will slow down. In fact, it is relatively speaking. There is no subjective change in time, but the time seen by others slows down.
In fact, time is an illusion. The meaning of this sentence is that time is meaningless. It may not even exist. Meal time is the same as any time of the day. There is no difference. You think mealtime is special just because society and culture make you think so. There is another thing that can prove that time is subjective, and that is the Mandela effect. Mandela once opposed the white democratic rule in South Africa. After fighting for 50 years, spending 28 years in prison, and becoming the first black President of South Africa, Mander once said: I have dedicated my life to eliminating racial discrimination and racial segregation. His purpose is actually very simple. He just hoped that whites and blacks could live harmoniously on the South African continent. In the end, Mandela relied on his own efforts to achieve this.
However, in the memory of many people, Mandela had already died in prison in the last century. What is going on? Nelson Mandela, the former President, died in 2013. The origin of all this began in 2010. Researcher Fianna, who studied paranormal phenomena, found that many people in different countries remember Nelson Mandela’s death in the 1980s. They recall TV reports, a funeral, and a speech by Mandela’s wife at that time. However, there is no evidence to support this. It is puzzling why so many people have this memory error. If one or two people have memory errors, it could mean they made a mistake. But if many people have made mistakes, could everyone have made a mistake?
Later, the American “supernatural blogger” Fianna Boomer called this phenomenon the Mandela Effect. The Mandela Effect specifically refers to the phenomenon that the public’s memory of certain historical events is completely inconsistent with the facts. Simply put, most people have collective amnesia or have formed false memories. There is currently no scientific evidence to prove the authenticity of this effect. Still, there needs to be more evidence to oppose it. Our memory is extremely susceptible to external factors and even our cognitive level. Mood can affect memory. Memory is affected by time experience. Memory problems may not be the issue. The foundation of memory, which is time, is subjective. This subjectivity affects how we perceive time. Perception, the constitution of memory, and the construction of reality.
In fact, your present moment and my present moment are not consistent. What is happening simultaneously may have nothing to do with me. The difference in time between you and me depends on the relative movement and position between us. Time is subjective and personal. However, if we consider it objectively, time seems like an illusion. It is a creation of humans.
The Quest to Unravel the Mystery of Time
Nevertheless, time does pass in reality. We can observe this when an apple detaches from the branch and hovers in the air. When we fall to the ground, we see that time is not an illusion but a fundamental part of the world. In the eyes of different people, time may be different. If you want to unravel the mystery of time, you need to start studying it from the moment the universe explodes.
Modern science believes that our universe was born in the Big Bang at a singularity 13.8 billion years ago. The singularity is a point with infinite mass, energy, heat, density, and infinitely small volume. After this point explodes, the universe is rapidly expanding in all directions. The universe took 13.8 billion years to expand into what we see now. The celestial bodies in the universe were all formed after the Big Bang. Scientists believe that the time was at the moment of the Big Bang. If we can know why the universe exploded, we can solve the mystery of time. However, it is too difficult to solve the mystery of the Big Bang. Scientists are still actively researching, and many loopholes exist in the mystery of the universe’s birth. The Big Bang Theory is only a relatively recognised view by the scientific community.
How did the universe originate? Is there someone behind all this? Scientists are currently actively researching. Humans, being the most intelligent beings on Earth, have always been curious and engaged in continuously exploring and studying the world’s mysteries. After thousands of years of technological development, humans have been able to Earth; this shows that human science and technology are developing quickly. The editor believes that humans will solve the mystery of time in the future by persisting in their efforts and advancing science and technology. I hope that this day will come soon. So, do you have anything to say?
