Events invoke time. - Dimensions of space and time:

Description of the unit of time, the second (s):

The second (s) is the SI unit of time. It is defined based on the fixed numerical value of the cesium frequency ΔνCs. The second is the duration of 9192631770 cycles of the radiation corresponding to the transition between two hyperfine levels of the cesium 133 atom. 

In other words, the second is defined as the time taken for a specific number of oscillations of the cesium atom, making it a reliable and precise unit for time measurement. The value of ΔνCs is 9192631770 Hz, which is equivalent to s^-1.


Events Invoke Time: 

Existential events by their very nature invoke time. In our reality, event or events are fundamentally tied to the concept of time. Whenever something happens or comes into existence, it does so within a temporal framework. Time is the dimension that provides the context in which events occur, and through the progression of time events unfold, develop and eventually cease to exist.

Here is a description of how existential events invoke time:

Temporal Sequence: Time enables the sequencing of events. Each event occurs one after the other or at a specific time. The concept of "before" and "after" is possible only because of time. For example, we can say that the force of gravity over time causes an object to fall to the ground before bouncing back up.

Duration and Persistence: Duration provides the duration for which the event exists. Whether it is a fleeting moment or a prolonged process, events have a temporal span The duration of an event can be infinitely short or extend over an extended period of time, and this duration is defined by time.

Cause and Effect: Timing is crucial for establishing causal relationships between events. Cause and effect are closely tied to the temporal order of events. A cause precedes its effect, and this temporal relationship is essential to understanding how events are interconnected in the fabric of reality.

Change and Transformation: Time is the canvas on which change and transformation take place. Events can evolve, change and change their status as time progresses. For example, plant growth from a seed to a mature plant is a process that unfolds over time.

Birth and Death: Time defines the beginning and end of events, including the birth and death of entities. Whether it is the birth of a star in the universe or the passing of a living organism, both events are characterized by their occurrence over time.

Perception and Experience: Our perception and experience of reality is intertwined with time. As conscious humans, we experience events in a temporal flux. Our memory, awareness and ability to recall past events or anticipate the future depends on our sense of time.

In short, existential events invoke time because time provides the framework within which events occur, persist, and change. Time is the invisible thread that weaves together the tapestry of existence, enabling us to understand the relationship between events and their unfolding within perceptible space.

Time: 

Time is a concept that defines the indefinite and continuous progression of past, present and future existence and events. It is a fundamental dimension that exists alongside the three spatial dimensions (x, y, and z). Time is regarded as an irreversible and unidirectional flow, meaning that events occur in a sequence that moves forward without the possibility of going back to a previous state.

The nature of time can be described as follows:

Indefinite progression: Time has no definite beginning or end; It extends infinitely in both directions. We can trace the events of history and look into the future, but there is no finite point that marks the origin or conclusion of time.

Including past, present and future: Time contains past, present and future as a unified whole. Events that occurred in the past led to the present moment, and current actions and decisions will shape what will unfold in the future.

Irreversible Flow: Time moves forward in an irreversible manner. Once an event occurs, it becomes part of the past and cannot be undone. There is no mechanism in our macroscopic reality that allows us to go back in time.

Uniform succession: Time progresses uniformly, meaning it moves at a constant speed without changing speed or direction. In our macroscopic reality, time is considered consistent and operates at a constant speed across all events and experiences.

Fourth Dimension: Time is considered the fourth dimension when added to the three perceptible spatial dimensions (x, y, and z). Together, these four dimensions provide a framework within which objects, events, and phenomena exist and interact in our observable reality.

Perceptible space is inextricably linked: time and the three spatial dimensions are intertwined. The unfolding of events within perceptible space invokes the concept of time. Events occur at specific points in space and are characterized by their temporal order. 

In short, time is an abstract dimension that encompasses the ongoing progression of existence and phenomena in our macroscopic reality. It is distinct from the three spatial dimensions and is considered an irreversible and unidirectional flow, which is integral to our understanding of the manifested universe. 

Dimensions of Space and Time: 

Perceptible space: This refers to the three spatial dimensions (x, y, and z) in which objects can be observed and experienced in our macroscopic reality.

Invisible dimensions: These are non-local dimensions beyond the three perceptible dimensions (x, y, and z) that are not directly observable or experienced in our macroscopic reality. One such invisible dimension is time (t).

Invisible Dimension (t): It specifically refers to time (t) as a separate and distinct dimension from the three spatial dimensions. Time (t) is one of the four fundamental dimensions that we experience, and although not directly observable to a spatial extent, the progression and sequence of events in perceptible space is called time (t).

Based on the given (x, y, z, t) coordinate system, the definitions are as follows:

x, y, z: Three spatial dimensions representing the length, width and depth of an object or event in perceptible space.

t: The time dimension represents the progression of events and the order in which they occur and is considered an invisible dimension.

With these definitions, we can further clarify:

Time (t) is considered an invisible dimension because we cannot directly perceive or experience time as a spatial dimension, but it is fundamental to describing the sequence and duration of events in our perceptible space.

Perceptible events are conceptual (time) = t: This means that in our perceptible space (x, y, z), events occur and invoke the concept of time (t) to describe their occurrence and duration.

In short, in the (x, y, z, t) coordinate system:

Realizable dimensions: x, y, z (local dimensions)
Invisible dimension: t (time dimension)

Time (t) is crucial to understanding the sequence and progression of events in our perceptible space. It is considered an invisible dimension because we cannot feel or experience it directly like the spatial dimension.

A 360° clock cannot display time dilation due to varying time scales:

The time scale for proper time (t) and the time scale for time dilation (t') are different. The time scale for proper time (t) is 360°, as represented by the 𝑇(𝑑𝑒𝑔) = 𝑇/360 equation. The time scale for time dilation (t') is greater than 360°, Since, Time scale for Time dilation > 360°. Since the two time scales are not the same, the clock that measures proper time (t) cannot display or measure time dilation (t') in the same units.

As per the Special Theory of Relaitivity, time dilation results from relativistic effects that cause time to run differently for the moving object compared to an observer at rest. Due to this difference, the time dilation cannot be directly measured using the same time scale (clock) used to measure proper time.

Conclusion: proper time (t) and time dilation (t') are associated with different time scales, and a clock that measures proper time cannot directly display or measure time dilation in the same units. The relativistic effects of time dilation cause time to be dilated or stretched for the moving object compared to an observer at rest, leading to different time scales for proper time and time dilation.

Mathematical Representation:

The equation of time dilation is 𝑑՚ = 𝑑/√(1 − 𝑣²/𝑐²) where 𝑑′ is dilated time, 𝑑 is proper time, v is relative speed, and c is the speed of light in free space.

  1. 𝑇(𝑑𝑒𝑔) = 𝑇/360 = (1/𝑓)/360 = ∆t; Time scale = 360 (𝑇/360); t < t';  
  2. Time scale for Proper time = 360°; Proper time = t; 
  3. Time scale for Time dilation > 360°; Time dilation = t';  
  4. Since, [Time scale for Proper time]  ≠  [Time scale for Time dilation];
  5. Therefore, Time scale (clock) for Proper time cannot display Time dilation.

Time distortions in clocks or oscillators having mass:

Time distortion is possible for clocks, or oscillators, with rest mass m, and applied speed v<c, or gravitational potential difference h>0, where, v and h denote velocity in m/s and height above ground in m, respectively.

However, when clocks undergo time distortion, electromagnetic waves do not undergo the same distortion, but such waves maintain a time delay of 3.335641 Β΅s/km; propagating at speed c, where, c represents the speed of light in free space. As such, redshift corresponds to time delay.

Mathematical Presentations for time distortions in clocks or oscillators:

1. If time distortion (π›₯𝑑) is possible for clocks or oscillators with the given rest mass (m), applied speed (v) < c, and gravitational potential difference (h) > 0. Where, rest mass (m) = 9.1093837 × 10^-31 kg;  height above ground (h) = 1 Km; v = 1 km/s.

To determine if time distortion (π›₯𝑑) is possible for clocks or oscillators with the given conditions, we need to check the two conditions:

v < c (object's speed is less than the speed of light).
h > 0 (there is a gravitational potential difference).

Given:
m = 9.1093837 × 10^-31 kg (rest mass)
v = 1 km/s = 1000 m/s (applied speed)
h = 1 km = 1000 m (height above ground)
g = 9.8067 m/s^2 (acceleration due to gravity)

v < c:
1000 m/s < 299792458 m/s (True)
The object's speed (v) is less than the speed of light (c), so condition 1 is satisfied.

h > 0:
1000 m > 0 (True)
The gravitational potential difference (h) is greater than 0, so condition 2 is satisfied.

Both conditions are satisfied, so time distortion (π›₯𝑑) is possible for clocks or oscillators with the given conditions. Time distortion occurs when an object's speed is less than the speed of light (v < c), and there is a gravitational potential difference (h > 0). In this case, both conditions are met, so time distortion is possible.  

2. If time distortion (π›₯𝑑) is possible for clocks or oscillators with the given rest mass (m), applied speed (v) < c, and gravitational potential difference (h) > 0. Where, rest mass (m) = 9.1093837 × 10^-31 kg;  height above ground (h) > 299792458 m; v = 299792458 m/s = c.    

To determine if time distortion (π›₯𝑑) is possible for clocks or oscillators with the given conditions, we need to check the two conditions:

v < c (object's speed is less than the speed of light).
h > 0 (there is a gravitational potential difference).

Given:
m = 9.1093837 × 10^-31 kg (rest mass)
v = 299792458 m/s (applied speed, equal to the speed of light c)
c = v (equal to the speed of light c)
h > 299792458 m (height above ground, greater than the speed of light c)
g = 9.8067 m/s^2 (acceleration due to gravity)

v < c:

299792458 m/s < 299792458 m/s (False)
The object's speed (v) is equal to the speed of light (c), not less than it, so condition 1 is not satisfied.

h > 0:

The given height above ground (h) is greater than the speed of light (c), h > c, which means there is a gravitational potential difference.

Both conditions are not satisfied, so time distortion (π›₯𝑑) is not possible for clocks or oscillators with the given conditions. 

Time distortion occurs when an object's speed is less than the speed of light (v < c), and there is a gravitational potential difference (h > 0). In this case, neither condition is met, so time distortion is not 

3. z is proportional to the time delay (π›₯𝑑):

To determine if there is a proportional relationship between redshift (z) and time delay (π›₯𝑑), we can compare the expressions for z and π›₯𝑑:

z = k (πœ†/360)
π›₯𝑑 = (πœ†/360)

From the above expressions, we can see that both z and π›₯𝑑 have the same term (πœ†/360) on the right-hand side. This indicates that z and π›₯𝑑 are proportional to each other, and the constant of proportionality (k) is equal to 1.

There is a proportional relationship between redshift (z) and time delay (π›₯𝑑) for the given expressions, and the proportionality constant is 1. 

This means that as the redshift (z) increases or decreases, the time delay (π›₯𝑑) will also increase or decrease in direct proportion.

Conclusions:

Time distortion (π›₯𝑑) is possible for clocks or oscillators with the given rest mass (m), applied speed (v) < c, and gravitational potential difference (h) > 0. When the rest mass (m) is 9.1093837 × 10^-31 kg, the height above ground (h) is 1 km, and the applied speed (v) is 1 km/s, both conditions are satisfied, and time distortion is possible.

Time distortion (π›₯𝑑) is not possible for clocks or oscillators with the given rest mass (m), applied speed (v) < c, and gravitational potential difference (h) > 0. When the rest mass (m) is 9.1093837 × 10^-31 kg, the height above ground (h) is greater than 299792458 m, and the applied speed (v) is equal to the speed of light (c), the first condition is not satisfied, and time distortion is not possible.

There is a proportional relationship between redshift (z) and time delay (π›₯𝑑). The expressions for redshift (z) and time delay (π›₯𝑑) both involve the same term (πœ†/360), indicating a direct proportionality between the two. The proportionality constant (k) is equal to 1.

The effective mass of electrons (mβ‚‘*):

In the 80s, in our electronics classes in semiconductor or solid state physics, such as semiconductor diodes, LEDs, transistors, integrated circuits, BJTs, thyristors, triacs, fets, mosfets and many more, we learned the effective mass of electrons, a very interesting topic, which I'm sharing now.

Electron effective mass (mβ‚‘*) is a concept in solid-state and semiconductor physics that describes the behavior of electrons in a crystal lattice or semiconductor material. In these materials, electrons experience periodic potentials, causing them to behave differently based on their momentum and the crystal's band structure. Effective mass is the modified mass of electrons, which can vary in different crystal directions. It is determined experimentally or theoretically from the element's electronic band structure. In some cases, the effective mass of electrons in a semiconductor can be negative, causing unusual phenomena like negative differential resistance.

It is important to note that the electron rest mass (mβ‚‘) is a fundamental constant and is always the same for electrons, regardless of the material in which they reside. On the other hand, electron effective mass (mβ‚‘*) is a material-dependent property that describes how electrons behave in certain materials under certain conditions.

Question: Lorentz transformation involves mass change but mass cannot be transformed into another form?

Answered by Others: The Lorentz transformation is a mathematical tool that helps understand how physical quantities change under relativistic conditions. It does not involve the direct conversion of mass into another form, such as energy or frequency. The Lorentz transformation deals with the relativistic effects of high velocities.

In the context of the Lorentz transformation, the mass of an object does not change. The concept of "relativistic mass" was introduced in the early days of special relativity to describe how an object's mass appears to change with its velocity. However, this concept has fallen out of favor in modern physics, and the more accepted view is that an object's mass is an invariant quantity, meaning it remains the same regardless of its velocity or the reference frame from which it is observed.

The Lorentz transformation does not involve any change in an object's rest mass. It is a mathematical tool used to understand how physical quantities vary between different inertial reference frames and is consistent with the principles of special relativity. Mass (m) remains an invariant quantity in all inertial reference frames, meaning its value remains the same for all observers, regardless of their relative velocities.
