Brief description and understanding of time as it applies to different situations.
Time is a fundamental requirement for the very existence of the universe irrespective of the presence of a conscious observer or not.This is because time is simply the rate of change of patterns ,which can also be defined in another way that time is the rate of flow of information .All information and the very basic information which we could think of is energy , if there was any failure of flow of information in the universe then it would cease to exist or get frozen at a particular moment,so if time didnt exist or ceased to exist, the universe would cease to exist .
Since time is related to the
rate of flow of all information in the universe including energy and from the laws of thermodynamics "energy can neither be created nor destroyed we could say that ,"Time can never be created nor destroyed"But just as the flow of energy can vary depending on the different parts or nature of space, it finds its self. So time varies according to the nature of space in which it finds itself in.
Time is so fundamental that it is responsible in a hidden way for the formation of the very matter and perhaps forces, this implies that "if energy flowed at a certain rate or at time "T" it would either become matter or not .
Thus Time = rate of flow of energy in the universe , Time = rate of flow of information =rate of flow of energy= speed of light and varies depending on the nature of space it is measured in and who is measuring it.
Time also has a relationship to the speed of light ,but light is also a flow of information for the conscious entities and therefore, that is why the speed of light and time are important in relativity.
In physics, time is considered to be a fundamental quantity that is not easily defined but is understood through its effects on matter and energy. In classical physics, time is viewed as a universal constant that progresses uniformly and independently of other physical quantities, such as mass and energy. However, in modern physics, time is recognized as being relative to an observer's position and motion in space.
The theory of relativity, developed by Albert Einstein in the early 20th century, fundamentally changed our understanding of time,but also fixed our minds strictly to an observer being present. According to this theory, time is not an absolute quantity but is instead a dimension that is intertwined with space to form spacetime. This means that the passage of time can vary depending on an observer's motion and location in space.This statement that the passage of time can vary depending on the observers motion and location in space is quit
important due to the fact that space is made up of multiple dimensions and not just the three dimensions that we are aware off. But if we have to accomodate quantum mechanics then other dimensions beyond our daily perception emerge, as we discover that there is more than what meets the eye.
In addition, quantum mechanics, which is another branch of modern physics, also suggests that time can be a more complex and subtle concept. In some interpretations of quantum mechanics, time is viewed as an emergent property that arises from the interactions of quantum systems.
It is said that nothing we are able to perceive is able to travel faster than light , The fundamental reason is that 'the speed of light' is actually 'the speed of information propagation', the rate at which information about any event in spacetime propagates away from it and towards the future.
Traveling faster than information would cause inconsistencies in the universe's history and the universe is built so that it does not allow inconsistencies.But it isn't so as there are alot of observations that have been observed that support faster than light motion that we shall look at later on. It just happens that our interpretation of information is based on light and we cant
make sense of any information traveling at speeds faster than light.
But that is best described as we simply can't perceive any information traveling faster than the speed of light ,which is a limitation on our part and not that of the universe.
When we compute anything traveling faster than light we find that it suddenly begins traveling backwards in time.
It's understandable that such a scenario can't be comprehended by a human mind but not by the universe. Assuming we could perceive anything, we would perceive 'the history film' in reverse motion. People would 'awake from death', get younger and end as a fertilized egg in their mother's uterus. Targets would be shot before any trigger was pulled.
since photons would move away from our eyes towards their source, sensory information would escape from our brains into the environment, instead of learning we would know less and less,we would only know memories, which we would gradually experience again and which would then simply disappear.
One wouldn't want to travel faster than light.
How ever we can now look at observations and effects in our universe that travel faster than light. A good example of travelling faster than light is the formation of all anti-particles , all anti-particles are mirror images of their matter particles which has been described as traveling faster than light and thus backward in time. So how does the universe achieve that under our noses?
In 1949 Richard Feynman devised a theory of antimatter.
The following is a description of a spacetime diagram for pair production and annihilation which appears to the right.
An electron is travelling along from the lower right, interacts with some light energy and starts travelling backwards in time.
An electron travelling backwards in time is called a positron. Then an electron travelling backwards in time interacts with some other light energy and starts travelling forwards in time again. Note that throughout, there is only one electron.
Nambu commented on Feynman's theory in 1950: "The time itself loses sense as the indicator of the development of phenomena; there are particles which flow down as well as up the stream of time; the eventual creation and annihilation of pairs that may occur now and then is no creation or annihilation, but only a change of direction of moving particles, from past to future, or from future to past." (Progress in Theoretical Physics 5, (1950) 82).
Dimensions and the interaction with different values of time and speeds of light in space .
In physics, a dimension is a measure of the size or extent of an object or a system, and it refers to the number of coordinates needed to specify the location of a point in that object or system.
In the space we live in, there are three dimensions: length, width, and height, which are also known as the X, Y, and Z axis, respectively. These dimensions are often referred to as the 3-dimensional space or 3D space.
It is important to note that in some areas of physics, particularly in theoretical physics, there are theories and models that propose the existence of additional dimensions beyond the three we experience in everyday life. These additional dimensions are often referred to as "extra dimensions," and there are several different theories about their nature and properties.
The behavior of objects and systems in different dimensions is governed by the laws of physics, just as they are in our three-dimensional world. However, the specific characteristics of objects and systems in higher dimensions can be very different from what we experience in our everyday lives.
For example, in a two-dimensional world, objects can only move along the X and Y axis, and they would not be able to move in the Z direction or experience depth. Similarly, in a four-dimensional world, objects could move along four axes, including time, which would allow them to experience time as a physical dimension in addition to the three spatial dimensions.
Mathematics plays a crucial role in understanding and describing the properties of objects and systems in different dimensions.
Many mathematical models have been developed to describe the behavior of objects and systems in different numbers of dimensions, including vector spaces, tensors, and differential geometry.
the concept of time is closely related to the speed of light and the theory of relativity. According to the theory of relativity, the speed of light is a fundamental constant that is the same for all observers, regardless of their relative motion.
In certain extreme conditions, such as near a black hole or in the early moments after the Big Bang, the effects of gravity and the high energy densities can lead to distortions in space and time, which can lead to time dilation and other effects.
One example of this, is gravitational time dilation, which occurs when an object is in a strong gravitational field. According to the theory of relativity, time passes more slowly in a strong gravitational field, and near a black hole, time can become so distorted that it appears to slow down or even stop for an observer far away.
Another example is the concept of cosmic inflation, which proposes that the universe underwent a period of rapid expansion in the first moments after the Big Bang. During this period, the universe expanded faster than the speed of light, and the concept of time as we know it, may not have existed in the same way.
There is no mathematical formula to describe a condition where time is equal to the speed of light, as this would violate the fundamental principles of relativity and causality. However, mathematical models and equations have been developed to describe the behavior of objects and systems in extreme conditions, such as those near a black hole or during cosmic inflation. These models and equations are based on the principles of relativity and other fundamental laws of physics, and they provide a framework for understanding the behavior of the universe in different conditions.
However if we looked at time as the speed of information transfer ,which information is indestructable as it is energy perhaps a way to address the above exists.
According to the theory of relativity, time dilation occurs in regions of space with different gravitational potentials or with different relative velocities. This means that time can appear to move slower in regions with stronger gravitational fields or at higher speeds relative to an observer.
In an atom, electrons orbit around the nucleus, which creates a small but measurable gravitational field. The speed of the electrons is also significant, as they travel at speeds close to the speed of light.
As a result, time dilation occurs in the atom, and time appears to move slower for the electrons than it does for an observer outside the atom.
In the nucleus of an atom, there are protons and neutrons, which are made up of smaller particles called quarks and gluons. These particles are held together by the strong nuclear force, which is one of the fundamental forces of nature. The strong nuclear force is extremely strong, but it only acts over very short distances, which means that the particles in the nucleus are packed very tightly together.
The high density and strong nuclear force in the nucleus create a very strong gravitational field, which causes time dilation. This means that time appears to move slower in the nucleus than it does for an observer outside the nucleus.
The effect of time dilation in atoms and nuclei is very small and can only be measured with very precise experimental techniques. However, it is a well-established prediction of the theory of relativity and has been confirmed by numerous experiments.
According to the theory of relativity, mass and energy are equivalent, and they can be converted into each other according to the famous equation E=mc², where E is energy, m is mass, and c is the speed of light.
The rate at which time flows is related to the energy and mass of a system through the concept of time dilation. According to the theory of relativity, time appears to move slower in regions with stronger gravitational fields or at higher speeds relative to an observer. This means that if a system has a high energy or mass density, the gravitational field it creates can cause time to flow more slowly.
To convert energy into mass, a system must have a sufficiently high energy density to create a gravitational field strong enough to slow down time to the point where the energy can "condense" into mass. This is the basis of pair production, where high-energy photons can create pairs of particles (usually an electron and a positron) with mass. The energy of the photon is converted into the mass of the particles, but this process can only occur if the photon has enough energy to create the mass and the gravitational field it creates is strong
enough to slow down time to the necessary degree.
The rate at which time would need to flow for energy to become mass, depends on the energy density of the system and the strength of the gravitational field it creates. In general, the higher the energy density and the stronger the gravitational field, the slower time would need to flow for energy to become mass. However, the precise rate of time flow required for energy to become mass would depend on the specific details of the system and the process involved.
I can provide a brief derivation of the equation E=mc² and its variation involving time dilation.
The equation E=mc² is a consequence of the theory of relativity, which relates energy, mass, and the speed of light. The basic idea behind the equation is that mass and energy are equivalent, and they can be converted into each other.
The derivation of E=mc² starts with the mass-energy equivalence principle, which states that the total energy of a system is equal to the sum of its rest energy (energy due to the mass of the system) and its kinetic energy (energy due to its motion):
E = E(rest) + E(kinetic)
According to the theory of relativity, the rest energy of a system is equal to its mass times the square of the speed of light:
E(rest) = mc²
Combining these two equations, we get:
E = mc² + E(kinetic)
Now, if we consider a system at rest (i.e., with zero kinetic energy), we get:
E = mc²
This is the famous equation E=mc², which shows that mass and energy are equivalent and can be converted into each other.
As for the variation involving time dilation, we can start with the formula for the relativistic energy of a particle:
E² = (mc²)² + (pc)²
Where E is the total energy of the particle, m is its rest mass, p is its momentum, and c is the speed of light. Using the relationship between momentum and velocity (p = mv) and the
equation for time dilation (t' = t/√(1 - v²/c²)), we can rewrite this equation as:
E² = (mc²)² + (mv)²c²/(1 - v²/c²)
Expanding and simplifying this equation, we get:
E = γmc²
Where γ is the Lorentz factor, which is given by:
γ = 1/√(1 - v²/c²)
This equation shows that the total energy of a particle is proportional to its mass and a factor that depends on its velocity relative to an observer. This factor takes into account the effect of time dilation, which causes time to flow more slowly for a moving object and increases its effective mass.
There fore we can see that Time is an extremely important part of the universe ,irrespective of the presence of an observer or not. It determines everything
by determining the flow of information in relation to the type of space or dimension it finds itself. Due to the fact that in our universe our perception is dependant
on electromagnetic force which is transmitted by a photon all our limititations seem to arise from a certain limit or constant and that is the speed of light .However the universe isn't limited by the
speed of light to transfer information or energy and adopts to the type of dimension it finds its self in .So in summary time can flow backwards when we exceed the speed of light ,Time can create matter when the speed of light is
extremely slow in a special kind of dimension etc.
