Relativistic effects on phaseshift in frequencies invalidate time dilation II

Thakur, Soumendra & Samal, Priyanka & Bhattacharjee, Deep. (2023). Relativistic effects on phaseshift in frequencies invalidate time dilation II. 10.36227/techrxiv.22492066.v2

𝑨𝒃𝒔𝒕𝒓𝒂𝒄𝒕: Relative time emerges from relative frequencies. It is the phase shift in relative frequencies due to infinitesimal loss in wave energy and corresponding enlargement in the wavelengths of oscillations; which occur in any clock between relative locations due to the relativistic effects or difference in gravitational potential; result error in the reading of clock time; which is wrongly presented as time dilation. 

Cosmic Influence in a Dark Energy Dominated Universe:

This research introduces the idea that gravitational redshift occurs within the gravitational influence of massive objects (e.g., galaxies), but as photons move beyond these regions, they also experience cosmic redshift caused by the influence of dark energy, which results in a greater observed redshift. This is a novel interpretation that suggests that the expansion of space driven by dark energy can affect the observed properties of photons, leading to a greater perceived distance traveled.

The Universe is composed of various components, with less than 5% being interactive baryonic matter, approximately 26% consisting of non-interactive but gravitationally interactive dark matter, and a substantial majority of over 68% being dark energy. This dark energy possesses an effective mass that is less than zero.

The relationship between gravity and dark energy is akin to a cosmic tug of war. While gravity exerts a force that draws galaxies closer together, dark energy exerts an opposing force, pushing these galaxies apart. This dynamic interplay is most evident in galaxies or clusters of galaxies, where zero-gravity spheres exist beyond the reach of gravitational influence. The overall expansion or contraction of the universe hinges on which force holds dominance at a particular time – gravity or dark energy. Dark energy, in particular, creates an anti-gravitational effect, consistently winning in this celestial tug of war. Beyond the gravitational influence of any object, there exists an ongoing contest between gravity and anti-gravity. Many fundamental principles of standard cosmological models describe the roles of gravity and expansion. This universal "tug of war" manifests itself as a dynamic, ever-changing universe, rather than a static one. This raises the fundamental question: How exactly is the universe evolving?

The structure of a typical cosmic cluster consists of three key mass components: matter mass (Mᴍ), dark-energy effective mass (Mᴅᴇ, with a value less than zero), and gravitating mass (Mᴳ). The dark energy backdrop exerts a more potent anti-gravity influence compared to the gravitational force of matter, resulting in the acceleration of cosmological expansion. This anti-gravity effect can be globally and locally stronger on scales ranging from approximately 1 to 10 Megaparsecs (Mpc). The effective density of dark energy, from a gravitational perspective, is negative, thus generating anti-gravity. Gravity dominates at distances within R < Rzᴳ, while anti-gravity becomes more pronounced at distances greater than Rzᴳ. A gravitationally bound system with a mass of Mᴍ can only exist within the zero-gravity sphere with a radius of Rzᴳ.

When considering the propagation of light, the concept of "light travel distance" comes into play. This distance refers to the path that light travels through free space in a given time. It is influenced by redshift and is calculated by measuring 'light travel time'.

In contrast, the 'proper distance' pertains to the separation between an observer and a source at a specific time 't'. This distance is not constant; it changes over time due to the continuous expansion of the universe. It signifies the distance between two galaxies at that specific time 't', which can vary as the universe continues to expand.

Gravitational Redshift:

Gravitational redshift occurs when a photon of light is emitted from a massive object (a "star") located at a distance (r) from the center of the object (the "star").

This process results in the stretching of the photon's wavelength, causing a "gravitational redshift" (λ/λ0) in the observed light.

Gravitational redshift is relevant within the gravitational influence of the massive object, such as a galaxy, specifically within the zero-gravity sphere of that galaxy with a radius (r) from its center.

Anti-Gravity and Cosmic Redshift:

The text introduces the concept of antigravity, driven by dark energy, which opposes gravitational effects.

The argument is that within the gravitational influence of a galaxy (up to the zero-gravity sphere), only gravitational redshift occurs. The speed of the photon remains constant at 'c' (the speed of light).

However, when the photon moves beyond the zero-gravity sphere (at a distance r from the center of the "star"), it begins to experience "cosmic redshift" in addition to gravitational redshift. Cosmic redshift is calculated as {(λ_obs - λ_emit)/ λ_emit}.

Effective Redshift:

The effective redshift of the photon is the combined effect of gravitational redshift (λ/λ0) and cosmic redshift {(λ_obs - λ_emit)/ λ_emit}.

The text concludes that the effective cosmic redshift is greater than the gravitational redshift. This implies that in regions dominated by anti-gravity (dark energy), the photon's relative distance is expanding at a greater rate than in regions of normal gravitational influence.

Interpretation:

The text suggests that the observed cosmic redshift in regions influenced by dark energy results in a "greater light traveled distance" compared to the photon's "proper distance" from its original emission point.

In simpler terms, this implies that in regions where dark energy dominates, the photon, while still traveling at its intrinsic speed ('c'), appears to be covering a larger relative distance due to the expansion of space.

Exploring the Limits of Existence: From the Planck Length to the Cosmic Unknown:

Your post seems to be grounded in the concept of existence. You've assumed that existence is eternal, and therefore, there can't be a starting point for existence. Based on this assumption, you've concluded that there is neither a beginning nor an end to the universe.

However, it's crucial to consider what existence truly means. While you might define it based on social or philosophical understanding, this definition doesn't align with how existence is interpreted in the realm of physical science.

Let's explore physical existence in terms of the Planck scale, specifically the Planck length. This scale marks the point where classical notions of gravity and space-time no longer apply, and quantum effects take over. Even before reaching the Planck length, our physical perception becomes ineffective, and we can never fully grasp anything beyond this threshold. The Planck length, approximately 1.616255×10^−35 meters, is defined by physical constants such as the speed of light, the Planck constant, and the gravitational constant. It serves as the limit of physical reality perception.

So, physical reality's inception occurs well before we reach the Planck length, and its end is when it reaches the Planck length. Our physical universe and existence are confined within this Planck threshold. We can't observe or measure anything beyond it, even with advanced technology in the distant future. The Planck length stands as our permanent perceptual limit.

While we may experience gravitational or antigravitational effects from existence beyond our physical perception, such existence holds no meaning within our physical domain because we can't perceive events and time from this imperceptible existence beyond our physical reality.

The notion of a beginning and an end is rooted in our limited perception. The Big Bang and Black Holes, for instance, hypothesize domains beyond our perceptual capabilities. The concept of a beginning and end of physical existence is mathematically possible beyond our perceptible reality.

Therefore, you cannot dismiss the idea of a beginning and an end to existence considering our physical limitations. Furthermore, your post doesn't account for the effects of dark energy and the gravitational influences of black holes, which we can perceive as interactions from the non-existent reality.

It's important to note that the Planck length represents a fundamental limit to our current understanding of physical reality. However, claiming that our physical universe's existence begins and ends strictly at the Planck length might be an oversimplification. While it serves as a lower limit for our perception, it doesn't necessarily define the boundaries of the universe itself.

Furthermore, acknowledging the existence of phenomena beyond our perception, such as dark energy and the gravitational effects of black holes, is essential. These interactions may provide insights into regions of the universe that we can't directly observe.

So in conclusion, it's essential to recognize that scientific understanding of existence and the universe is a complex field that extends far beyond our current comprehension. While the Planck length is a crucial concept, defining the precise boundaries of the universe based solely on it remains a topic of ongoing research and debate. Additionally, accounting for phenomena like dark energy and black holes is crucial in our quest to comprehend the universe fully.

Navigating the Balance Between Abstraction and Physical Intuition in Fundamental Physics:

Physics is ultimately a physical science, and the goal is to describe and understand the physical world. Concerns about excessive abstraction are not new in physics and have been criticized and debated for decades.

I strongly emphasize that physics should be rooted in physical, intuitive concepts rather than highly abstract mathematics. I am therefore concerned with the shift from physical reality to abstract mathematics in fundamental physics, and I present my view that this shift is significant.

Relative time dilation is an example of this concern. It is a "real" or "natural" time that deviates from the concept of abstract time. I have a preprint research paper that addresses the time dilation problem and debunks it.

I strongly take the view that abstract concepts, such as virtual particles, interaction exchange theory, probability waves, curvature of spacetime, black holes, big bang, etc., are mistakenly accepted as physical reality. This concern is shared by a minority of physicists who argue for a more conservative approach to theoretical concepts, demanding a closer connection to empirical data and physical intuition.

The claim is highly plausible that physicists may be driven to adopt highly abstract and sensational models in order to gain public acceptance, leading to the introduction of absurd concepts into fundamental physics. It is true that concepts like black holes and the Big Bang have captured the public imagination and can influence the direction of research.

The tension between mathematical abstraction and physical intuition is a long-standing challenge in physics. Although mathematics is a powerful tool for modeling and understanding the physical world, it is essential for physicists to ensure that their mathematical models are based on experimental evidence and not divorced from reality.

The adoption of abstract concepts in physics often follows from their ability to explain and predict physical phenomena. Although caution is required, some abstract concepts have proven highly successful in doing so, such as the mathematical framework of quantum mechanics.

Public perception and recognition can influence the direction of research, but this is not unique to physics. Many scientific fields experience this phenomenon. The challenge is to balance communicating exciting ideas with maintaining rigorous scientific standards.

Open-mindedness is critical to collaboration and paradigm shifts within subfields. However, specialization is a natural consequence of the increasing complexity of physics, making collaboration and communication even more important.

The idea of an expert panel to evaluate research is attractive but may face challenges related to bias and the potential to slow down the publication process. It is important to ensure that such panels maintain objectivity and transparency.

The discussion raises valid concerns about the state of fundamental physics research. However, it is important to note that the scientific community constantly evaluates and evolves its theories and models. Physics remains a dynamic field, and ongoing dialogue and peer review are essential to its progress.

This short paragraph is misleading and wrong? A confusing and incorrect reiteration:

Reiteration, ''Consistency of Total Photon Energy: We reiterate the core principle that in strong gravitationalfields, the total energy of a photon remains constant, as expressed by the equation Eg = E. The 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 (4) (PDF) Photon Interactions in Gravity and Antigravity: Conservation, Dark Energy, and Redshift Effects. Available from: 

www.researchgate.net/publication/374264333 [accessed Oct 12 2023]. (Photon Interactions in Gravity and Antigravity: Conservation, Dark Energy, and Redshift Effects)

This short paragraph is misleading and wrong. What happens to a photon in a gravitational field is the following:

  • h∆f=hf/c²g∆H.

h is Planck’s action constant. f is the photon frequency, ∆f is the change of the photonfrequency, c is the speed of light, g is the gravitational field strength, H is the height in the gravitational field, h∆f is the energy gain or loss of the photon according of changing its height in the gravitational field by ∆H.

We get ∆f/f=g∆H/c². g is the mean value between H and H+∆H.''

The Author Answers:

I see your pointing out, 'this short paragraph is misleading and wrong';

So let me explain the basic difference between the equation I provided, Eg = E and your equation h∆f (= ∆E).

It's evident that "Eg = E" and "hΔf = hf/c²gΔH" address different aspects of a photon's interaction with gravitational fields. Wherewas, my explanations highlights that "Eg = E" focuses on the conservation of the total energy of a photon within an external gravitational field, while "hΔf = hf/c²gΔH" pertains to local energy changes within a single gravitational well. Additionally, the mention of "Δλ/λ" as a representation of intrinsic energy changes helps differentiate these concepts further.

1. Your explanation, 'what happens to a photon in a gravitational field is the following:

h∆f=hf/c²g∆H.

where "h∆f" represents the energy gain or loss of a photon as it changes its height in a gravitational field by ∆H. It quantifies the energy change of the photon due to its change in height within the gravitational field. This aligns with the concept that a photon loses energy as it moves away from a massive object (the source of gravity) or "escapes a gravitational well."

The equation "∆f/f = g∆H/c²" in the quoted text is a simplified form that shows the relative change in photon frequency (and hence energy) as a function of the gravitational field strength (g) and the change in height (∆H) within the gravitational field. It is consistent with the idea that a photon loses energy (or experiences a change in frequency) while moving within a gravitational well.

However, the inconsistency arises when one equation focuses on local energy changes within a single gravitational well, while the other equation takes into account the cumulative effect of multiple gravitational fields:

(A1) what is incosnsistent in your presentation is that, the change in height (∆H) mentioned in the previous comment is specific to the source gravitational well that the photon is escaping. It represents the change in altitude or position within that particular gravitational field. It does not directly take into account other gravitational fields that the photon may encounter in its transit path.

The equation "hΔf = hf/c²gΔH" and the equation "0 = Δρ - Δρ" describe different aspects of a photon's interaction with gravity.

(a) "Eg" represents the energy state of a photon within an external gravitational field, and "Eg = E" signifies the conservation of energy, meaning that a photon's total energy within a gravitational field remains the same as its initial intrinsic energy "E." Despite any local changes in energy or frequency that might occur as a photon moves through gravitational fields (as represented by ΔE), the total energy of the photon remains constant, with respect to (Eg). The idea that within a gravitational field, even though there may be local variations or changes, the overall energy of the photon does not change, and the equation ΔEg = 0 is a reflection of this conservation of energy. This is consistent with the broader principles of physics, where the conservation of energy is a fundamental concept.

(b) Your equation: "hΔf = hf/c²gΔH" focuses on how the energy (and frequency) of a photon changes due to the specific gravitational well it is within. In this context, ΔH represents the change in height or position within a particular gravitational field, which indeed influences the photon's energy. This equation primarily pertains to the effects of a single gravitational field.

Whereas, my equation presented, "0 = Δρ - Δρ" refers to the concept of effective deviation, emphasizing how photons respond to multiple gravitational fields along their path. It suggests that even though photons may experience local changes in momentum as they move through different gravitational fields, the net change in momentum over the entire journey equals zero. This principle aligns with the concept of geodesics in general relativity, where particles, including photons, follow curved paths determined by the combined gravitational influences of all massive objects in their vicinity.

The inconsistency arises when your equation focuses on local energy changes within a single gravitational well, while the other equation takes into account the cumulative effect of multiple gravitational fields.

To provide a more comprehensive and consistent description of a photon's journey, it's important to consider both the local changes in energy within specific gravitational wells (as in "hΔf = hf/c²gΔH") and the overall path and effective deviation that accounts for all gravitational fields encountered (as in "0 = Δρ - Δρ").

(A2) It is well established fact that the photon expends energy while escaping a gravitational well (its source)," is a fundamental concept in general relativity. In this context, a photon is considered to lose energy as it climbs out of a gravitational well. The relevant equation that describes this phenomenon is known as the gravitational redshift equation, which is derived from Einstein's theory of general relativity.

The gravitational redshift equation is as follows:

Δλ/λ = GM/(rc²)
Where:
Δλ/λ is the relative change in the wavelength of light emitted by the photon.
G is the gravitational constant.
M is the mass of the object creating the gravitational well (the source of gravity).
r is the radial distance from the center of the gravitational well to the location of the photon.
c is the speed of light in a vacuum.

This equation shows that as a photon moves away from a massive object (the source of gravity), its wavelength increases. In other words, the photon loses energy as it escapes the gravitational well. This effect is commonly referred to as gravitational redshift or gravitational blueshift, depending on the direction of the photon's motion.

So, when the photon escapes a gravitational well (such as the gravitational field of a massive celestial body), it does so with less energy than when it was closer to the source of gravity. This concept is a key prediction of general relativity and has been experimentally confirmed.

The equation "Δλ/λ = GM/(rc²)" focuses on the local change in energy within a single gravitational well and how this affects the photon's wavelength and energy. This equation takes into account the gravitational field produced by a single massive object.

On the other hand, "0 = Δρ - Δρ" considers the overall path and effective deviation of the photon as it encounters multiple gravitational fields along its journey. It accounts for the cumulative effects of these fields on the photon's trajectory.

The inconsistency arises when your equation focuses on local energy changes within a single gravitational well, while the other equation takes into account the cumulative effect of multiple gravitational fields. To provide a more comprehensive and consistent description of a photon's journey, it's important to consider both the local changes in energy within specific gravitational wells (as in "Δλ/λ = GM/(rc²)") and the overall path and effective deviation that accounts for all gravitational fields encountered (as in "0 = Δρ - Δρ"). 

"Eg" represent the total energy of a photon within an external gravitational field and I am not focusing on changes in the photon's intrinsic energy represented by "Δλ/λ," then the context and interpretation of your equations would be specific to the total energy state of the photon as it encounters external gravitational fields. (Eg) does not represent (Δλ/λ) which is inherent to photons intirnsic energy (E - ΔE).
