Philosophers and scientists are perplexed in describing the actual physical nature of time. On one hand, time feels tangible because we can tentatively see the passage of time in our everyday lives. As well, we use mechanical measurements of time, which further promotes our sense that it is a physical property. Yet on the other hand, the concept of time is so elusive that scientists cannot contain it as a quantifiable sum; every attempt to physically quantify time as a substantive constituent has resulted in persistent conceptual and mathematical paradoxes.
Time becomes a non-paradoxical concept when defined as a arbitrary measurement of duration, and not a physical component of matter, energy, or space. The progressive interactions of matter and energy are mechanical processes, no different from one gear turning another in a succession of events. We are dependent on time as a temporal tool to measure the mechanical progressions of events, but the event itself is not dependent on time to occur. Time is a measurement of duration, just as an inch is a measurement of length, neither cause nor affect what they measure.
The measurements of time in hours, minutes, and seconds are artificial values that we use to coordinate the sequential relationship between events. Time as a temporal value is an essential tool in expressing the motion of velocity, acceleration, and duration. Without the measurement of time, motion would be impossible to calculate. The sensation of physical time is taken for granted as fact, and there lays the problem; our neural sense of time has inadvertently been perceived as fact, a material thing, when in reality, it is only a neurological process.
The awareness of time passing is a neurological process (sensation) generated by our brain. Our brain uses circadian time to regulate our body metabolism. The temporal sense of time is an organizational strategy that helps us navigate our environment. Our sensory systems are energy detectors; sight for electromagnetic energy, sound for kinetic energy, taste and smell for atomic or molecular energy, and touch for pressure or thermal energy. Time is not a form of energy, so we do not detect it through sensory stimulus; we only neurologically perceive it in relationship to progressive events around us.
Time is subjective. A child's temporal sense of time is different from an adult's sense of time. A child's sense of minutes can seem like hours; a child may ask, "Are we there yet," every few minutes as if it had been hours. An adult may ask "How long until we get there," every few hours. Perceptions of time are generated by many subjective factors; while waiting to use a restroom, seconds can seem like minutes, or minutes seem like hours; whereas, waiting to take a dreaded physics test, hours can seem like minutes, and minutes can seem like seconds. Perceptual time is a matter of neural status that determines our subjective sense of temporal reality.
If you were in a dark box for hours and days, you would not have a definable sense of time, other than the progression of moments, but no definition of how long the moments are in seconds, minutes, hours, or days. With no events to coordinate time, time would just be the progression of thoughts, one after another, with no definition of measured time. Two people, in two different boxes, would develop different perceptions of time passing, based on their individual neurology. Even if they had a watch to monitor the passing of time, they would still develop neural distortions of time as it relates to the everyday world. The value of a minute in a dark box would seem much different than the value of a minute while driving, talking, or reading. Time is a perception that coordinates interactivity.
When a traumatic event occurs, such as a car accident, our sense of time can vary, seemingly to move faster or slower than normal. In dreams, our sense of time seems normal, whereas dreams can feel like hours or days long, but in actuality, they are only seconds long. Drugs can alter our neural sense of time. Long-term isolation can distort our sense of time. Many environmental and neurological factors and conditions can alter our sense of time.
People learn about time through movies and books that tell adventurous stories of time travel, compelling people to dream about traveling through time. People believe these concepts of physical time because the entertainment industry has promoted time-travel as a real futuristic science. So strong is this induced compulsion that DARPA, NASA, DOD, and other governmental agencies, along with private institutions, are investing vast resources - trying to explore and develop time-travel. The concept of time as a physical component of existence is an induced case of mass hysteria, generated by Relativity and the entertainment industry.
Scientists tell the world that 'physical time' or the 'universe' started approximately 13.7 billion years ago. They based this estimation largely on reversing the motion of galaxies to an elusive point of singularity, though they cannot point to a spot in the sky that is the center. They also measure time through evaluating the farthest spot of light they can see, and gauging its dim factor (how bright something is,) to determine its theoretical distance expressed in terms of light-years. As well, scientists use the Doppler Effect to also tentatively gauge time distance, but many factors such as gas and dust, heated space, and magnetic fields can affect Doppler shift, and over such a great distance is unreliable. These are all theoretical measurements based upon invented values. Scientist use measurements of age, distance, and gravity as a simulation to prove physical/material time, because they have no other evidence to quantify the nature of time.
Unfortunately, scientists have made a physical science out of the science fiction concept of time, portraying it as a material attribute of the universe, when in reality, it is just a neurological process designed to coordinate our actions and behavior. There are no timeons, time-dimensions, or wormholes (time channels through space) in nature. Time is only a measurement of duration, a vector, no different from the measurements of direction or position.
Science will never be able to time travel. Time is not tangible; science will never be able to travel backwards, sideways, or forwards in time, because it is only a neural perception, and not a physical property. Events are linear chain reactions of motions and interactions. The concept of time is not a material component or property of the event. The concept of time is solely an arbitrary fractionated measurement that we apply as a finite vector of duration. Time is not a substantive material that can be captured and stored in a box.
The truth about the concept of time is that it is only a subjective neurological process, a simulation generated by our brain. Nature evolved this neural sensation to give us a tool to perceive and interact with the motions of our environment. Time coordinates perception into action; a sensation neurally generated to negotiate/navigate the material world about us. The perception of time only exists in our mind to coordinate internal rhythms and exterior navigation. In other words, time synchronizes our motion within the motions of the world we live in.
This all seems contrary and counterintuitive, but it is accurate. Time, like light, seems obvious, but in reality, they are only neural illusions. A physicist would tell you time is a tangible/physical component/property of space and matter; a philosopher would tell you time is subjective; a biologist would tell you that time is a metabolic circadian process; and a cognitive scientist would tell you time is a neurological temporal process. Each science has a different perceptual view of time, because each employs different functionality and applications.
The concept of time is used in many different ways throughout science and philosophy. Essentially, time is our neurological coordinator that navigates the obstacles and motions of the world around us. That is non-disputed. However, orthodox science believes that time is more than just a neural construct; science believes that time is a physical construct; something that can be altered, shaped, and twisted into pathways to other places and times, i.e., time traveling.
Think it through for yourself and decipher what the nature of time is? If you take someone's word for it, that is faith not science. How the brain processes data is as important as the data itself. You must understand the mechanics of the brain before you can understand the data that it processes, and the impressions it formulates. Twist and flip a few neurons in the brain, and it changes the temporal impressions of time.
In conclusion: Physical time does not exist. Time is only an arbitrary neural measurement of duration, not a physical or mechanical component or property of matter, energy, or space...
Additional data on 'Time' can be found in topics, The nature of "Light and Colors," and, The nature of "Dreams." As well, there is an enormous amount of data on the Internet with different perspectives. Research and learn about what it is to be human, and why we 'believe and behave' as we do. All you have to lose is ignorance.
