According to a dictionary, illusion is defined as something that appears natural but doesn’t exist. For example, fantasy, delusion, false impression and fiction. I will tell you one instance, Most of you know about the movie Tarzan. The character Tarzan, raised by a mountain gorilla, didn’t know about the actual human lifestyle. So he began to live like a gorilla in the jungle. Once he learned about humans, he realised who he is. Here I have one question, is the past life of Tarzan an illusion for him? Would he manage the sudden change? Whoever at that time thought the world was an illusion? Why did I ask this? Because we create our society, language, culture, religion, races etc. Everything in the world is made by us, including “time”.
1. Truth (reality) is eternal and unchanged.
2. Real exist anytime.
Human life is full of thoughts and emotions. These thoughts and emotions are just part of life, but they are not living. All humans survived life only by thoughts and emotions. We only think about life but fail to live life. If you have excellent ideas for one person, your emotions towards that person are lovely and comfortable. Is it genuine that the person is friendly to all? It’s just an illusion. One unique way of living and experience creates perception. Perception is something that looks right, feels right but does not exist. For example, we see things as real and natural in our dreams, but they are just an illusion when we wake up. While you are dreaming, you are transported to a world that is different from the waking world. In the waking world, you probably still think you are “you”. In the dream world, it feels real, and the waking world also feels authentic. Few of you think it is insane, but you believe the more profound you get and realise something is there.
The types of illusion are caused by distortion in a sense (stimulus):
1. Optical (visionary) illusion: caused by distortion in the sense of vision.
2. Tactile illusion: caused by distortion in the touching sense.
3. Auditory illusion: caused by distortion in the sense of hearing.
Is time an illusion?
Does time only move forward? How do you distinguish the past, present and the future? You can get it by a general theory of relativity. E.g., Suppose you saw a car drive past you. You are still on the ground, but your mind would perceive the car and the car’s passengers moving at the same speed as the car because their rate is relative to your position.
Meanwhile, the passengers feel like stationary objects inside the car since their motion matches the car motion proportion to the outside world. Still, Einstein’s theory of relative motion could be applied to all objects in the universe. One exception to relativity is light. Light moves at a constant velocity. It leads Einstein to conceive a link between time and space. The perception of how time passes can differ from two spectators. Rely upon how speedy one is moving compared to the other. The passing of time is universal since humans agreed to this time system to organise our lives. In contrast, time is a convenient tool for tracking the past, present and future. Once you realise the past, present and future could all exist at once.
The star Proxima Centauri is closest to the earth, and it is only about four light-years away. So the light from the star you see now is four years old in our time. If Proxima Centauri exploded, we would know about it until after four years, as the speed of light is constant. Another thing is that the faster you move, the slower time it goes. For example, you know the movie “Interstellar”, directed by Christopher Nolan. The main characters are Cooper and Murph. Cooper travelled. After the wormhole, he reached the Millar planet. At that time, the character roomily stayed in space. Cooper spends more than an hour while roomily waiting for twenty-three years and gets old. After much struggle, Cooper gives binary codes to the Murph to solve the gravitational equation. Later Cooper reached Cooper station built by Murph. In Starting the age of Cooper is 35 and age of Murph is 10. When he arrives at the cooper station, he has the same age, and Murph gets older than his father.
Science of illusion:
You take a tennis game. For the ball to get to the other side of the court, our brain needs time to process incoming sensory input. One in ten seconds in advance, our brain processes the visual information about the location of the ball it reaches. The recipient sees the ball on a particular site. It takes one in ten seconds for the receiver brain to figure out what he is seeing? For the information at that time of sensing still, the ball is moving. How relevant is this? Actually, in professional tennis, the ball has moved seven meters in that time. The receiver is seeing the ball seven meters behind where it is. How does the brain manage the interaction with the ball? The answer is that the brain predicts the near future. Our brain knows about its delay and tries to compensate for them by predicting what will happen. We’ve seen that “now” in our brain is the past, predominantly.
An illusion is just a misinterpretation of something. So the more you question, the more you will get.
