Conservation, Dark Energy, and Redshift Effects:

Abstract:
This paper delves into the intricate interactions of photons in the realms of gravity and antigravity. Photons, being fundamental particles of light, exhibit remarkable behaviors as they traverse through the cosmos. They journey through the vast expanses of the universe until they venture into the enigmatic invisible realm. The photon's encounters with gravity and antigravity are explored in detail. When confronting the gravitational influence of massive objects, such as celestial bodies, photons neither gain nor lose energy, but they exchange momentum with the external gravitational field while steadfastly preserving their intrinsic momentum. Intriguingly, the photon's interaction with the mysterious force of antigravity, propelled by dark energy, presents an irreversible transformation. The consequences of this interaction are profound, as photons undergo a cosmic redshift of a magnitude greater than that induced by gravity or other redshift mechanisms. This distinctive effect manifests as the photon departs from the gravitational embrace of galaxies and embarks on a journey beyond their boundaries, where the domain of zero gravity commences. 

Furthermore, the paper elucidates the dynamics of external forces exerted by massive objects on photons during their interactions. These forces momentarily carry the photons while they engage with the massive objects. Yet, despite this external assistance, the photons maintain their original momentum. Notably, within a gravitational field, the effective deviation from this transportation remains zero, reaffirming the photon's commitment to its initial trajectory.

1. Introduction:
This paper delves into the intriguing realm of photon interactions within the gravitational and antigravitational landscapes. Photons, as fundamental particles of light, play a pivotal role in the cosmos, journeying through the fabric of space and encountering various external forces along their path.

One of the remarkable attributes of photons is their unvarying speed, always traversing at the cosmic speed limit, the speed of light, unless subjected to interactions with matter. Within the scope of this exploration lies the enigmatic phenomenon of photons venturing into the invisible universe, a domain beyond the grasp of current observational instruments.

These interactions encompass the intricate interplay between photons, gravity, and antigravity, with dark energy serving as a mysterious driving force. Here, photons exchange momentum with the gravitational field of massive objects, sustaining their intrinsic energy, and yet, they succumb to the inexorable influence of antigravity, leading to an irreversible cosmic redshift.

This paper unravels the complex dynamics of photon behavior, shedding light on their resilience in the face of gravity and their ultimate surrender to the cosmic forces that govern the cosmos. Through a comprehensive analysis of these interactions, we aim to deepen our understanding of the fundamental principles that govern the behavior of photons in the universe and the enigmatic realms they traverse.

2: Fundamental Photon Characteristics

In this section, we will describe the fundamental properties of photons, including their masslessness and constant speed in a vacuum. We will also explain how photons always travel at the speed of light (c) from the moment of their creation. To do so, we will reference the equation E = hf to underscore the relationship between photon energy and frequency.

Masslessness of Photons: Photons are elementary particles that possess a unique property – they are completely massless. Unlike most other particles in the universe, photons do not have any rest mass. This intrinsic characteristic of photons sets them apart from other particles and plays a crucial role in their behavior.

Constant Speed in a Vacuum: One of the most remarkable features of photons is their constant speed in a vacuum. Photons always travel at the speed of light (c) from the very moment of their creation. This speed is approximately 299,792,458 meters per second (or about 186,282 miles per second). Unlike objects with mass, photons do not need to accelerate to reach this speed; they are born with it. This principle is a fundamental aspect of Albert Einstein's theory of special relativity.

The Equation E = hf: To understand the relationship between a photon's energy (E) and its frequency (f), we turn to the equation E = hf. This equation, known as the Planck-Einstein relation, reveals that the energy of a photon is directly proportional to its frequency. Here, E represents the energy of the photon, h is Planck's constant, and f is the frequency of the photon. In simple terms, higher-frequency photons carry greater energy.

By highlighting these fundamental characteristics of photons, we lay the groundwork for a deeper exploration of their interactions with gravity, antigravity, and their behavior in different environments. Photons, being massless and always traveling at the speed of light, exhibit unique properties that have far-reaching implications in the realm of physics and cosmology.

Now, let's delve into the interactions of photons with gravity and antigravity as described in the quoted paper.

Photon Interactions in Gravity and Antigravity:

The photon travels until it disappears into the unobservable universe. It interacts with gravity, antigravity caused by dark energy, and other external forces. Here, we examine how these interactions affect photon energy and momentum.

Gravitational Interaction:

When a photon encounters the gravitational influence of a massive object, it exchanges momentum (Δρ) with the external force field of gravity.

According to the equation (E + Δρ = E - Δρ), the photon neither gains nor loses energy during this interaction but experiences changes in momentum.

The effect of the photon's interaction with the external gravitational force is reversible. The photon maintains its intrinsic momentum and returns to its original path after releasing the gravitational interaction.

The effective deviation from its initial trajectory in the gravitational field is zero (0 = Δρ - Δρ).

Antigravity Interaction:

In contrast, when a photon interacts with the external force of antigravity caused by dark energy, the effect is irreversible (ΔEc).
This interaction results in cosmic redshift (zc), which is more pronounced than gravitational or other types of redshifts.

A photon's interaction with antigravity occurs when it moves beyond the influence of a galaxy and enters the zero-gravity sphere of radius.

By understanding these interactions, we gain insight into how photons navigate complex gravitational and antigravitational environments. These phenomena have implications for our understanding of the cosmos and the behavior of light in the universe.

3: Photon Behavior in Gravity

In this section, we will explore how photons interact with gravity, the familiar force that attracts objects with mass. We will explain that photons neither gain nor lose energy when crossing a gravitational field, emphasizing the equation ΔEg = 0 to underscore the conservation of photon energy and momentum in a gravitational field. We will also introduce the concept of effective deviation (0 = Δρ - Δρ) and describe how photons return to their original path after gravitational interaction, drawing references from the previously quoted papers.

Photon Interaction with Gravity: Photons, despite being massless particles, do interact with gravity. Gravity is the force that attracts objects with mass, and when photons pass through a gravitational field created by a massive object like a planet or star, they experience gravitational effects.

Energy Conservation in Gravitational Fields: One of the remarkable aspects of photon behavior in a gravitational field is that they neither gain nor lose energy during this interaction. This conservation of energy is expressed by the equation ΔEg = 0, where ΔEg represents the change in photon energy due to gravity.

ΔEg = 0: This equation highlights that the change in photon energy (ΔEg) as it passes through a gravitational field is zero. In other words, the photon's energy remains constant before and after the gravitational interaction. This phenomenon is a consequence of the masslessness of photons and is a fundamental principle in the behavior of light in the presence of gravity.
Momentum Exchange: While photons do not experience a net change in energy, they do undergo changes in momentum (Δρ) as they interact with the gravitational field.

Effective Deviation: The concept of effective deviation (0 = Δρ - Δρ) illustrates that, despite changes in momentum during gravitational interaction, the photon ultimately returns to its original path.

0 = Δρ - Δρ: This equation signifies that the effective deviation of the photon from its initial trajectory is zero. In simpler terms, the photon's path is not permanently altered by the gravitational interaction. Instead, it may experience a temporary deviation but ultimately resumes its original course.
By understanding these principles of photon behavior in gravity, we gain insight into how light interacts with massive objects and how it maintains its energy and momentum even in the presence of gravitational forces. This knowledge is fundamental in the study of astrophysics, general relativity, and cosmology, as it helps us comprehend phenomena like gravitational lensing and the bending of light by massive celestial bodies.

4: Antigravity and Irreversible Effects

In this section, we delve into the intriguing concept of antigravity and its counteracting force to gravity. We explain how antigravity exerts an irreversible effect on photons, primarily through cosmic redshift. Additionally, we define cosmic redshift (zc) and elucidate that it occurs when a photon departs from the influence of a galaxy. We also introduce the notion of the zero-gravity sphere of radius as the boundary marking the transition where antigravity begins to influence photons, drawing references from the previous discussions.

Antigravity Concept: Antigravity is introduced as a hypothetical force counteracting gravity. While gravity attracts objects with mass toward each other, antigravity serves as a conceptual opposite, pushing objects apart.

Irreversible Effect on Photons: Antigravity is emphasized as having an irreversible effect on photons, distinguishing it from the interactions with gravitational fields discussed earlier.

Cosmic Redshift (zc): Cosmic redshift (zc) is defined as a critical phenomenon associated with antigravity. It occurs when a photon leaves the gravitational influence of a galaxy and enters a region where antigravity begins to exert its influence. Cosmic redshift results in a change in the photon's characteristics, including its wavelength and energy.

Zero-Gravity Sphere of Radius: The concept of the zero-gravity sphere of radius is introduced as the boundary that marks the transition between regions influenced by gravity and those influenced by antigravity. Within a galaxy's gravitational influence, photons behave in a conventional manner, while beyond this boundary, antigravity's effects become significant.

By exploring these aspects of antigravity and its effects on photons, we gain insights into the hypothetical forces that may exist in the universe and how they impact the behavior of light. While antigravity remains speculative in the realm of physics, considering its potential effects on fundamental particles like photons opens the door to fascinating possibilities in our understanding of the cosmos.

5: Photon-Electron Interactions in Dense Transparent Media

In Section 5, we shift our focus to the intriguing topic of photon interactions with matter, particularly within dense but transparent media. We explore how photons can be absorbed by electrons in such environments, temporarily converting their energy into electron energy. Furthermore, we elucidate the phenomenon wherein electrons in an excited state subsequently release excess energy in the form of photons, resulting in noticeable time delays. Our discussion draws references from the previously mentioned papers to provide a comprehensive overview of these interactions.

Photon-Matter Interactions: This section serves as a transition into the realm of photon interactions with matter. It emphasizes the significance of understanding how photons behave when they encounter dense but transparent media.

Absorption by Electrons: We describe how photons can be absorbed by electrons within the atoms of dense, transparent materials. During this process, the photon's energy is transferred to the electron, causing it to transition to a higher energy state (e + ΔE).

Excited State and Excess Energy: We elaborate on the consequences of photon absorption, highlighting that the excited electron remains in this higher energy state temporarily. This period of excitation eventually culminates in the release of excess energy (E - ΔE) as photons.

Time Delays: We emphasize that the emission of these new photons introduces a time delay (Δt) in the progress of the original photon through the medium. The cumulative effect of multiple interactions adds up to create a noticeable delay in the photon's journey.

By exploring these photon-electron interactions within dense transparent media, we gain insights into the intricate behavior of light when it encounters matter. This knowledge is fundamental in various scientific and technological applications, spanning fields such as optics, materials science, and the design of optical devices. Understanding how photons interact with electrons in these environments is crucial for the development of technologies ranging from lenses to fiber optics and beyond.

6: Equations Describing Photon-Matter Interactions

In Section 6, we delve into the mathematical framework that underlies photon-matter interactions. We present fundamental equations that characterize these interactions, such as E = hf, ΔE = hΔf, f/Δf, and E/ΔE, to elucidate how photons undergo changes in energy and frequency during their encounters with matter. This section draws upon references from the previously discussed papers to provide a comprehensive understanding of the mathematics governing these phenomena.

E = hf: This foundational equation, known as the Planck-Einstein relation, establishes the intrinsic relationship between a photon's energy (E) and its frequency (f). It is represented as E = hf, where E denotes the energy of the photon, h represents Planck's constant, and f signifies the frequency of the photon. This equation underscores that the energy of a photon is directly proportional to its frequency.

ΔE = hΔf: Building upon the Planck-Einstein relation, this equation introduces the concept of changes in photon energy (ΔE) corresponding to changes in frequency (Δf). It reveals that a change in frequency results in a corresponding change in photon energy, with Planck's constant (h) serving as the proportionality factor.

f/Δf: This expression represents the ratio of the initial frequency (f) to the change in frequency (Δf). It quantifies how much the frequency of the photon changes due to interactions with matter. This ratio provides valuable insights into the extent of frequency alterations during photon-matter interactions.

E/ΔE: Similarly, this expression represents the ratio of the initial photon energy (E) to the change in energy (ΔE). It quantifies how much the energy of the photon changes during interactions with matter. Understanding this ratio is essential for comprehending the energy transformations that occur when photons interact with electrons within materials.

By presenting these equations, we establish a mathematical foundation for understanding the dynamics of photon-matter interactions. These equations enable us to quantify the changes in energy and frequency that photons undergo as they interact with matter, thereby contributing to our comprehension of fundamental processes in optics, materials science, and quantum mechanics.

7: Time Delay in Photon Passage

In Section 7, we explore the concept of time delay (Δt) in the passage of photons through matter, particularly in dense but transparent media. This phenomenon arises as a result of the cumulative effect of photon-electron interactions. We draw upon references from the previously discussed papers to provide insights into how these interactions contribute to time delays in photon propagation and how this concept is relevant in the field of optics and telecommunications.

Cumulative Effect of Photon-Electron Interactions: Within dense but transparent media, photons can interact with electrons, leading to processes such as absorption, excitation, and re-emission. These interactions, when considered collectively, give rise to a time delay (Δt) in the passage of photons. As photons encounter and interact with numerous electrons within the medium, each interaction contributes to a slight delay in the photon's progress through the material.

Group Velocity Dispersion: The concept of group velocity dispersion becomes relevant in this context. Group velocity dispersion refers to the phenomenon where different frequencies of light travel at slightly different speeds through a medium due to their interactions with electrons. It is particularly pertinent in the field of optics and telecommunications, where precise timing and synchronization of optical signals are crucial.

By introducing the idea of time delay in photon passage and connecting it to group velocity dispersion, we provide a comprehensive understanding of how photon-electron interactions can impact the propagation of light in dense but transparent media. This section underscores the significance of considering time delays in practical applications such as optical signal transmission, where the precise timing of signals is essential for reliable communication.

8: Photon Energy Variation in Strong Gravitational Fields

In Section 8, we delve into the intriguing topic of how photon energy behaves within strong gravitational fields. We reference equations and concepts from our previous discussions to elucidate the variation of photon energy in these environments and highlight the importance of energy conservation.

Photon Energy Variation: Within strong gravitational fields, photons interact with gravity, leading to changes in their energy. We reference the equation Eg = E + ΔE = E - ΔE to express the total energy of a photon in such conditions. Here's how we describe this variation:

Eg = E + ΔE = E - ΔE: This equation represents the total energy of a photon (Eg) in a strong gravitational field. It is expressed as the sum of its initial energy (E) and the gain (ΔE) or loss (-ΔE) of energy due to the gravitational influence. This equation emphasizes that, despite gravitational effects, the total energy of the photon remains constant. In other words, the photon conserves its energy even when subjected to the influence of a massive object's gravitational field.

Consistency of Total Energy: In this section, we stress the importance of maintaining the equivalence of total energy, even in the presence of strong gravitational forces. We emphasize that changes in photon momentum (Δρ), whether gains or losses, do not alter the total energy of the photon. This concept underscores the fundamental principle of energy conservation, even within the context of gravitational environments.

By presenting the equation Eg = E + ΔE = E - ΔE and reiterating the constancy of total energy in strong gravitational fields, we provide a comprehensive understanding of how photons navigate these challenging environments while adhering to the conservation of energy. This section contributes to a deeper comprehension of photon behavior in the presence of gravity, enriching our knowledge of fundamental physics principles.

9: Momentum and Wavelength Changes under Gravitational Influence
In Section 9, we delve into the fascinating realm of how photons undergo changes in momentum (Δρ) and wavelengths (λ) when influenced by strong gravitational fields. We reference equations and concepts from our previous discussions to provide a comprehensive explanation of these changes.

Changes in Photon Momentum: When photons traverse strong gravitational fields, they encounter changes in momentum. We present the equations Eg = E + Δρ = E - Δρ to elucidate these changes:

Eg = E + Δρ = E - Δρ: This equation represents the total energy of a photon (Eg) in a strong gravitational field. It is expressed as the sum of its initial energy (E) and the change in momentum (Δρ) due to the gravitational influence. This equation emphasizes that the photon experiences changes in momentum while maintaining constant total energy. These changes in momentum can result in gravitational redshift or blueshift, depending on whether Δρ is positive or negative.

Wavelength Changes: In this section, we explore how the wavelengths of photons are altered when subjected to strong gravitational forces. We introduce the equation h/Δλ = h/-Δλ to illustrate these changes:

h/Δλ = h/-Δλ: This equation relates the change in photon wavelength (Δλ) to the Planck constant (h) and the change in momentum (-Δρ) due to gravity. It demonstrates that as photons move through gravitational fields, their wavelengths experience shifts, which are determined by the changes in momentum. A positive Δλ signifies gravitational redshift, where the wavelength increases, while a negative Δλ represents gravitational blueshift, where the wavelength decreases.

By presenting the equations Eg = E + Δρ = E - Δρ and h/Δλ = h/-Δλ, we provide a comprehensive understanding of how photons undergo changes in momentum and wavelengths when influenced by strong gravitational fields. These equations serve as fundamental tools for describing photon behavior in the presence of gravity, enriching our comprehension of the interplay between photons and gravitational forces.

10: Consistency of Photon Energy in Gravitational Fields

In Section 10, we reinforce the fundamental concept of the constancy of total photon energy in the presence of strong gravitational fields, represented by the equation Eg = E. Additionally, we highlight the symmetry in changes in photon momentum (Δρ) and introduce the Planck length-to-time ratio (ℓP/tP) to elucidate its significance.

Consistency of Total Photon Energy: We reiterate the core principle that in strong gravitational fields, the total energy of a photon remains constant, as expressed by the equation Eg = E:

Eg = E: This equation underscores that the total energy of a photon (Eg) remains unchanged despite the influence of a strong gravitational field. This constancy of energy is a fundamental property of photons in such environments, emphasizing their resilience to external forces.

Symmetry in Changes of Photon Momentum: We emphasize the symmetry in changes of photon momentum (Δρ) caused by gravitational effects. As previously discussed, photons experience changes in momentum while maintaining constant total energy. This symmetry in momentum changes is a key characteristic of photon behavior in gravitational fields.

Planck Length-to-Time Ratio (ℓP/tP): To further enrich our understanding, we introduce the Planck length-to-time ratio (ℓP/tP). While not explicitly covered in earlier sections, this ratio plays a crucial role in the quantum realm, where the Planck length (ℓP) represents the smallest meaningful length scale and the Planck time (tP) is the shortest possible time interval. Their ratio (ℓP/tP) is a fundamental constant in physics and is relevant when considering extreme conditions, such as those encountered in strong gravitational fields.

By reiterating the constancy of total photon energy (Eg = E), emphasizing the symmetry in changes of photon momentum (Δρ), and introducing the Planck length-to-time ratio (ℓP/tP), Section 10 contributes to a comprehensive understanding of photon behavior in gravitational fields. These concepts and equations collectively enhance our grasp of the intriguing interplay between photons and the profound forces of gravity.

11: Conclusion

Photons can be temporarily absorbed by electrons, converting into electron energy, and subsequently, this energy is released as photons after time delays.
