Is time an illusion?

Is time an illusion? In the hustle of our daily lives, we often hear people around us urging us to hurry up, or we would not have enough time. Some say that they are so busy they don't have enough time. What is time? Is it when the sun rises in the morning and changes when the sun sets at night? Or is it the movement of the second hand on the clock? Generally speaking, we think of time as something simple and basic that passes evenly. From the past to the future, it can also be measured by a clock. Would you believe it if we said that the concept of time does not exist, and that it is only an illusion of the mind? Let's talk about the mystery of time. In 1851, a strange man was reported wandering through a German village, speaking only bits of broken German. He said his name was Joffa Vorring, and claimed to come from a part of the world known as Sakria. He spoke and wrote in unknown languages, which he called Luxarian. He told authorities that he was looking for his long-lost brother, but appeared in the village after encountering a shipwreck. There was another report in 1986 of a man named Pedro Oliver Ramirez, who was driving from Seville to a town called Alcalá de Guadera, when he went around a curve and allegedly found himself on a six-lane highway he had never seen before. He continued driving down this straight road, seeing unfamiliar buildings and roadside. After continuing to drive on the highway for an hour, he spotted a sign pointing in three different directions. One was labeled Malaga, the other was Sevilla, and the last was Alcabala. He took the Sevilla detour, and without fully knowing why, he was standing outside his home in Alcalá de Guadera. Frustrated and confused, he tried to retrace his steps, but could never find the crossroads or the triple road sign. Fast forward to 2008. A Spanish woman, Lorena Garcia, woke up one day to find that her world had suddenly changed in some strange ways. Her bedsheets were unfamiliar, and the pajamas she was wearing were different from the ones she had gone to sleep in. Her day got weirder when she went to work and discovered that she worked in the same building, but in a different department, under a boss she had never met. She also discovered that her current boyfriend is her ex-boyfriend, and her new boyfriend, whom she had been dating for a few months, was nowhere to be found. The woman was found to be in good physical and mental health. So what happened? There are many more unexplained phenomena like these. Could it be possible these people experienced some sort of time travel or ended up in parallel dimensions? Let's take a look at what our scientists have found about the mystery of time. Aristotle's view of time. What is time? The first person known to ask this question was the famous ancient Greek scientist and philosopher Aristotle. In his work Physics, he formulated the first classical view of time. What it simply means is that time is a measure of change. For example, someone went out in the morning for two hours and then returns home. Hence these two hours are a measure of a change that occurred between leaving and returning home. Perhaps someone will ask, according to Aristotle, if everything is not in motion and does not change, then does time also stand still and cease to exist? If Aristotle could hear this question, he would most definitely answer yes. But some would then ask, why is it that when I turn off all the lights at night and lie motionless in bed falling asleep, I can still feel the passage of time? Aristotle also pondered this question when he wrote his book Physics. In the book, he mentions that even if the body does not move, your mind is thinking. Once the mind thinks, we immediately assume time has passed. He said Newton's absolute time. Some people may find Aristotle's idea of time a little strange. This is understandable as we were taught Newton's concept of time in modern physics. Isaac Newton, the greatest mathematician and the most influential scientist of all time, believed that time is absolute and exists independently of any perceiver and progresses at a consistent pace throughout the universe. Even if all objects remain motionless, even if the activity of our souls were frozen, time would still pass, unaffected by anything. Newton used the letter T to represent time in his physics equations. Einstein Time is an illusion Aristotle and Newton, the two most powerful scientists of their time, both gave different views on the subject of time. People were caught in between the two theories and pondered whose view was the truth. Suddenly, another significant scientist, Albert Einstein, appeared with his theory of relativity. Einstein's statement was even more confusing when he said, Time is an illusion. The distinction between past, present and future is only a stubbornly persistent illusion. This theory was too avant-garde for many people to accept. So how is this meant to be understood? Einstein believed that there is no absolute time or space in this world, and he proposed a theory of the unity of space and time. In other words, time and space are the same, called spacetime. Physicists call the matter that makes up the world field, such as the temperature field or the electromagnetic field, and hence many experts say that spacetime is a gravitational field. Gravitational fields are no different from any other matter in the world. The world is a superposition of several fields, of which the gravitational field is one layer, and like other fields, it is neither absolute nor uniform and fixed. It can bend and stretch and interact with other fields. With this theory, spacetime can also be as smooth as a flat surface, which is the version described by Newton that we are familiar with, but the field can also fluctuate, as is the case with the gravitational waves, which can contract and expand. Einstein's theory of relativity contains two theories, special relativity and general relativity. According to special relativity, time passes more slowly for fast-moving objects than for stationary objects. On the other hand, general relativity says that time passes more slowly for objects in strong gravitational fields than for those in weak gravitational fields. In other words, for a person standing on the ground, time passes more quickly for the head than it does for their feet, because the head is further away from the ground where the gravitational field is weaker. So it looks like there might be some scientific basis for the claim that doing a handstand can be a good way to improve your beauty. So is Einstein right or not? Let's have a look at some classic examples. Atomic Clock Experiment In 1971, there was an experiment by two scientists, Joseph Hafele and Richard Keating, using four cesium atomic clocks. These atomic clocks used the standard frequency of the atomic nucleus to calculate and maintain the accuracy of time. The International Bureau of Weight and Measures reported in 2020 that a certain cesium atomic clock in Germany had an error of not even a second over 187 million years. Therefore, it would be a very reliable tool to use in an experiment measuring whether time has changed or not. For the experiment, Hafele and Keating placed two cesium atomic clocks on two commercial airliners travelling around the world in opposite directions, one going east and one going west, and compared them to another atomic clock located at the US Naval Observatory. What were the results of the experiment? The atomic clock on the plane flying east in the direction of the Earth's rotation, which means it was at a faster relative speed, was 59 nanoseconds slower than the one on the ground in the observatory, while the atomic clock on the plane flying west at a slower relative speed was 273 nanoseconds faster than the one on the ground. Einstein's theory of general and special relativity was verified simultaneously. Even the GPS positioning systems we use today require calibration daily, otherwise the atomic clocks on satellites would be 38 microseconds faster than the time on the ground each day. Don't think this is not significant. If left uncorrected, the GPS would accumulate a positioning error of about 10 kilometers each day. The NASA Twin Experiment In 2015, America's NASA did a special human biology experiment involving a pair of twins. Astronaut Scott Kelly and his brother Mark are identical twins, which means they share the same genome. NASA sent Scott into space, where he spent 340 days on the International Space Station. Mark stayed on Earth, awaiting Scott's return to compare the genetic changes in the two men to study the effects of space life on the human body. When you look at the photos released by NASA, does it seem that Scott looks younger after being in space and flying around Earth at high speed? However, since NASA had not released any photos of the two men before they took part in the experiment, we can't say for sure whether Scott would have looked younger. However, NASA's research does prove that Scott is aging slower than Mark. It turns out that when NASA did genetic testing, they found that Scott's body aged significantly slower during his time in space. This was because the telomeres, located at the ends of chromosomes, shortened at a lower rate. Telomeres are the small segment of DNA found at the end of a cell's chromosomes, and their function is to prevent damage to the chromosomes. As people age, telomeres become shorter and cells gradually age and die. In a twin space experiment, Scott's telomeres slowed down, while Mark's continued to age at a normal rate. However, when Scott returned to Earth, his telomeres soon went back to the normal rate of shortening. There is an ancient Chinese saying that a day in heaven is a thousand days on Earth. In different positions and spatial dimensions, the rate of change in time is completely different. In one dimension, a day may have just passed, but on Earth, we may have already experienced the rise and fall of a civilization. Is it possible that the people in the cases we mentioned at the start of this video accidentally came from another spacetime? Block Universe Based on Einstein's theory of relativity and the four-dimensional view of the universe as the unity of spacetime, in 2015, Bradford Scow, a professor of philosophy at the Massachusetts Institute of Technology, proposed a theory of the block universe. It describes how the past, present, and future all coexist now in a four-dimensional universe, which consists of three dimensions of space and one dimension of time. All movements that exist are relative to each other and have their coordinates in spacetime. The block of the universe is static, standing still in four-dimensional spacetime. There is no passage of time, no movement of the stars. The world is a static piece and each point on the timeline corresponds to an image of three-dimensional space at that instant. The whole moving universe is made up of countless such images of three-dimensional space. If we could look outside the block universe, it would be as if we were watching a film in this world. You can choose any point in time to watch what is happening at that moment. We all know that when we press the play button, the movie will continue playing. So block universe theory also has a corresponding button where humans feel the irreversible passage of time. MIT physicist and philosopher Max Tegmark and the British physicist Julian Barbour argued that this button is our brain. The passage of time is an illusion of our brain that the neuronal structure of the brain allows us to remember the past but will not tell us what will happen in the future. That's why memory gives people an illusion that time is passing and everything is moving from past to the present and into the future. If this is true of the universe, how can we transcend the illusion and see the past, present and future? Is it possible for anyone to do so given the current state of science? The Serial Universe Different dimensions have different time. In 1934, a British soldier, aeronautical engineer and philosopher John William Dune wrote a book about his precognitive dreams and a theory of time which he later called serialism. We have previously done videos about people with precognitive dreams such as the Japanese comic artist Ryo Tatsuki. Please check out our comment section below on the video Predictions COVID-19 will suddenly disappear. He believes time varies in different dimensions. Our physical brain inhabits in one time dimension, our conscious mind inhabits the next level of time dimension and so on all the way to an ultimate consciousness like our soul. He proposes that when we die, only our physical body in the initial level of time dies. Our higher selves are outside of this time and are effectively immortal. His theory was never accepted by mainstream science. It is possible that science today is not yet advanced enough to fully explain the mystery of time. The story of the Shakya clan In ancient India, after King Virudhaka had usurped the throne, he decided to destroy the Shakya clan, the home of Buddha Shakyamuni. It is said that three times in succession, Shakyamuni sat on the road that his army must take to dissuade King Virudhaka. On a fourth occasion, Shakyamuni did not stop him and the Shakya clan was annihilated. When one of Shakyamuni's disciples Moggallana asked Shakyamuni about why this happened, Shakyamuni explained that long ago, King Virudhaka used to be the kingfish in the water who was eaten by the people who lived by the river. His flesh was shared amongst 500 people who were the Shakya clan. At that time, Shakyamuni was a small child who did not eat the fish but out of curiosity had once struck the kingfish three times on the head. It was for this reason that Shakyamuni actually had a headache for three days after he became Buddha. After the kingfish reincarnated as King Virudhaka, he targeted the Shakya clan, wiping it out completely. As for what would happen to King Virudhaka, Shakyamuni predicted that seven days after the massacre, King Virudhaka and his army would definitely be destroyed. Sure enough, seven days later, King Virudhaka and his army perished in the big storm. So how did Buddha know the future without any access to scientific studies and theories? According to the Buddhists, those who practice cultivation and enlightenment have insight into fate and are able to observe the past, present and future. In that case, is Buddha the greatest scientist of all? So what are your thoughts on time? Is it absolute or is it an illusion? If you have any comments, please share them here.
