Abstract:

This paper explores the role of piezoelectric crystal oscillators in understanding various effects on material deformation. Piezoelectric crystals, such as quartz, are pivotal in electronic oscillator circuits due to their ability to generate an electric charge in response to mechanical stress, a property known as inverse piezoelectricity. The study examines how these oscillators operate with a high Q factor, providing stable frequency oscillations influenced by factors like mechanical deformation, temperature, and gravitational potential differences. The paper also discusses the relationship between wave distortions and time distortions due to relativistic effects, highlighting that wavelength distortions, caused by phase shifts in frequency, are directly linked to time distortions through the relationship λ ∝ T. Additionally, the analysis includes a comparison of theoretical concepts with practical observations from atomic clocks and the effects of phase shifts on time distortions in different frequency ranges.

The Piezoelectric Effect is the ability of certain materials to generate an electric charge in response to applied mechanical stress. A crystal oscillator is an electronic oscillator circuit that uses a piezoelectric crystal as a frequency-selective element. It relies on the slight change in shape of a quartz crystal under an electric field, a property known as inverse piezoelectricity. A voltage applied to the electrodes on the crystal causes it to change shape; when the voltage is removed, the crystal generates a small voltage as it elastically returns to its original shape. The quartz oscillates at a stable resonant frequency, behaving like an RLC circuit but with a much higher Q factor (less energy loss on each cycle of oscillation). Once a quartz crystal is adjusted to a particular frequency (which is affected by the mass of electrodes attached to the crystal, the orientation of the crystal, temperature, and other factors), it maintains that frequency with high stability.

Relativistic effects, such as speed or gravity of real events, cannot interact with the proper time (t) referred to in the fourth dimension. Relativistic effects, such as the speed or gravity of real events, cannot interact with the proper time (t) referred to in the fourth dimension. The term 1/√1-v²/c² in the equation of time dilation does not influence or interact with the proper time (t) to cause time dilation (t′). Wave distortions correspond to time distortions due to relativistic effects. Wavelength distortions, caused by phase shifts in relative frequencies, correspond exactly to time distortion through the relationship λ∝T.

Piezoelectric crystal oscillators demonstrate that errors in waves correspond to time shifts due to relativistic effects, mechanical deformation, motion, gravitational potential differences, and temperature. These oscillators show that wave changes correspond to time shifts under these conditions.

Piezoelectric crystals follow the equations F = ma and F = kΔL. Specifically, piezoelectric crystals also adhere to F𝑔 = G (m₁m₂)r², where m₂ is the mass of the piezoelectric material. Even very small changes in mechanical force or gravitational forces (G-force) cause internal particles of matter to interact, leading to stresses and associated deformations in the internal matter.

Material deformation can occur due to various causes, including:

• Wavelength distortions due to phase shifts in frequency.
• Mechanical forces causing stresses.
• Gravitational potential differences and forces.
• Relativistic effects.
• Temperature changes, causing thermal expansion, contraction, and stress.
• Electromagnetic forces, such as electric and magnetic fields.
• Chemical reactions, including corrosion and oxidation.
• Pressure, including hydrostatic and atmospheric pressure.
• Radiation, such as ionizing radiation and radiation pressure.
• Environmental factors, such as moisture and freeze-thaw cycles.
• Manufacturing processes, such as welding, casting, or machining, which can introduce residual stresses over time.

These causes correspond to time distortion in oscillation through the relationship λ∝T.

Applicable equations include:

F = ma, 
F = kΔL, 
F𝑔 = G (m₁m₂)/r².

The wave equation, in combination with the Planck equation, has successfully identified distorted frequencies due to the relativistic effect that has the influence factor. Therefore, events invoke time but not vice versa. What special relativity represents in time dilation is not time, and time dilation does not involve actual time. It is rather an error in the clock oscillation.

An atomic clock, which measures time by monitoring the resonant frequency of atoms, is based on the principle that electron states in an atom are associated with different energy levels. In transitions between such states, they interact with a very specific frequency of electromagnetic radiation. This phenomenon serves as the basis for the International System of Units' (SI) definition of a second: The second, symbol s, is defined by taking the fixed numerical value of the caesium frequency, Δvcꜱ,  the unperturbed ground-state hyperfine transition frequency of the cesium-133 atom, to be 9192631770 when expressed in the unit Hz, which is equal to to s⁻¹.

Phase Shift and Time Distortion:

The time interval T𝑑𝑒𝑔 for 1° of phase is inversely proportional to the frequency (f). For example, a 1° phase shift on a 5 MHz wave corresponds to a time shift of 555 picoseconds (ps).

For a wave of frequency f = 5 MHz

1° of phase shift = 1/360f

T𝑑𝑒𝑔 = 1/(360 × 5 × 10⁶),
T𝑑𝑒𝑔 = 555 ps.

Therefore, for 1° phase shift for a wave with frequency f = 5 MHz the time shift (Δt) is 555 ps.

Moreover, for a 360° phase shift or 1 complete cycle for a wave having frequency 1Hz of a 9192631770 Hz wave, the time shift (Δt) is approximately 0.0000001087827757077666 ms.

For a 1455.50° phase shift or 4.04 cycles of a 9192631770 Hz wave, the time shift (Δt) is approximately 0.0000004398148148148148 ms or 38 microseconds per day.

Applicable Equations:

1° phase shift

T𝑑𝑒𝑔 = 1/360f.

For a 1° time shift/distortion:

Δt = 1/360f.

Where:

• Δt is the time shift/distortion for 1 degree phase shift.

For an x° time shift/distortion:

Δtₓ = x(1/360f).

Where:

• Δtₓ is the time shift/distortion for x degrees, 
• x is the number of degrees of phase shift.

Erroneous Transformations: Lorentz Factor in Classical Mechanics

Abstract:

The Lorentz factor,  γ = 1/√(1-v²/c²), is a mathematical construct developed by Hendrik Lorentz and later incorporated into Albert Einstein's theory of special relativity. This factor, along with its associated transformations, introduces concepts specific to relativistic mechanics that deviate from classical mechanics. While the Lorentz factor and transformations are integral to special relativity, they can be seen as "simple transformations" within relativity, contrasting with the "deformations" observed in classical mechanics. Classical mechanics remains effective in describing motion and gravitational interactions, even at speeds approaching the speed of light, as evidenced by research on the Coma cluster of galaxies by A. D. Chernin et al., which integrates classical mechanics with considerations of dark energy and local dynamical effects. The Lorentz factor’s role in special relativity highlights the non-intuitive modifications introduced by relativity to classical concepts. Ultimately, it serves as a mathematical tool rather than a physical theory, reflecting Einstein's unconventional integration of mathematical concepts into physical theory.

Critique of Gravitational Lensing and Spacetime Distortion

Soumendra Nath Thakur
04-08-2024

The original post raised questions about the inapplicability of time dilation in special relativity (1905) on a standardized time scale. While time dilation is indeed not applicable on a standardized time scale, the comment questions the phenomenon of gravitational lensing as predicted by general relativity theory (1916).

Gravitational lensing occurs when a large amount of matter creates a gravitational field that distorts and magnifies light from distant galaxies. However, the phenomenon of gravitational lensing is not a consequence of spacetime curvature but rather the symmetric exchange of photon momentum (Δρ). This relationship between the external gravitational field and object motion raises questions about the necessity of including spacetime distortion in gravitational theory.

The behaviour of photons in strong external gravitational fields reveals the interactions between photon energy, momentum, and wavelength. The conservation principles involved demonstrate how changes in wavelength affect photon energy while maintaining total energy constancy. The direct impact of the gravitational field on object motion is proven to be indisputable in eradicating spacetime distortion


Why Time Dilation is Not Possible
A 360° time scale is always fixed, and a 360° clock dial cannot be greater than >360° or less than <360°. Thus, the 360° movement of the hour hand or second hand should be exactly one hour and one minute, respectively. Any deviations from this should be known as an error in time. This is why time dilation is not possible since a 360° time scale cannot accommodate dilated time unless there is an error in time.

Coordinate Transformation and Time Distortion: The Interdependence of Space and Time in Relativistic Spacetime

Soumendra Nath Thakur

01-08-2024

Abstract

In the context of relativistic interpretation, time dilation (t′) induces a transformation in spacetime coordinates, impacting the entire spacetime fabric and resulting in changes in the coordinates (x', y', z', t'). This dilation, reflecting the fusion of space and time into a unified four-dimensional continuum, alters the perception of events. Specifically, an event P occupying spacetime will experience changes due to the interdependence of space and time in special relativity. Consequently, the coordinates of event P in the moving frame will differ from those in the rest frame, illustrating the relativistic effects of time dilation on the spacetime continuum.

In relativistic physics, the fusion of space and time into spacetime implies that variations in the time coordinate (due to time dilation) are accompanied by corresponding changes in spatial coordinates. This interdependence is governed by Lorentz transformations, which maintain the invariance of the spacetime interval for all observers. Thus, dilation in the time coordinate leads to corresponding changes in spatial coordinates, culminating in a transformation of both time and space, known as spacetime dilation.

As a result, the event P, situated within such dilated spacetime, will be affected by this distortion. The perception and coordinates of event P in the moving frame will reflect the relativistic effects of dilation on spacetime, leading to differences from those in the rest frame. This underscores that time dilation can be viewed as a form of time distortion due to relativistic effects.

Where (t₁ - t₀) = elapsed time.

Explanation

Cosmic Expansion:

t₀ < t₁ = (t₀+Δt) → (x₀,y₀,z₀,t₀) < (x₁,y₁,z₁,t₁)

Where (t₁ - t₀) = (Δt) (elapsed time), 

Here: 

• c is the speed of light, considered a constant.

• The distance between event points (x₁,y₁,z₁,t₁) - (x₀,y₀,z₀,t₀) is greater than c.

Space-Time Dilation: 

t < t′ → (x,y,z,t) < (x′,y′,z′,t′)

Where t′ is dilated time, 

Here: 

• Dilated time t′ - t ≠ Δt (change in time)

• c is constant in the rest frame. 

• c ≠ constant in the moving frame.

• t′ - t ≠ Δt (change in time).

Comparison between Cosmic Expansion and Space-Time Dilation: 

• For constants:

(x₀,y₀,z₀,t₀) = (x,y,z,t)

• For dilation:

(x₁,y₁,z₁,t₁) ≠ (x′,y′,z′,t′)

Explanation and Analysis:

1. Cosmic Expansion:

• Describes how distances between cosmic objects increase over time due to the expansion of the universe.

• The elapsed time Δt represents the time interval during which this expansion occurs.

• The speed of light c is constant, but the distance between event points can exceed c due to the expanding universe.

2. Space-Time Dilation:

• Reflects the relativistic effect where time dilates (slows down) for objects in motion relative to an observer or in a strong gravitational field.

• The dilated time t′ differs from the uniformed change in time Δt, indicating the effects of relative motion or gravity.

• The speed of light c remains constant in the rest frame but may vary in the moving frame due to relativistic effects.

3. Comparison:

• Cosmic expansion deals with large-scale cosmological phenomena driven by factors like dark energy, leading to an increase in distances between cosmic objects.

• Space-time dilation deals with local relativistic effects where the fusion of space and time leads to changes in the perception of events and coordinates.

• The comparison highlights that while both phenomena involve changes in space and time, their causes and scales are different. Cosmic expansion is a large-scale effect, whereas space-time dilation is a relativistic effect experienced locally.

This explanatory presentation provides a clearer distinction between cosmic expansion and space-time dilation, emphasizing their unique characteristics and how they affect space-time differently

Is space-time dilation conceptually equivalent to space-time expansion?


Relativistic space-time is described as a four-dimensional continuum comprising three dimensions of space and one dimension of time. In this framework, space and time are interwoven, forming an integrated space-time fabric. As time dilates due to relativistic effects, does this interconnected nature imply a dilation of space-time as a whole?

For context:

Cosmic Expansion: Describes how the distance between cosmic objects increases over time, which can be represented as:

t₀ < (t₀+Δt) = t₁ → (x₀,y₀,z₀,t₀) < (x₁,y₁,z₁,t₁)

Where (t₁ - t₀) = elapsed time.

Space-Time Dilation: Reflects how time dilation in relativistic contexts affects space-time coordinates:

t < t′ → (x,y,z,t) < (x′,y′,z′,t′)

Where t′ is dilated time

Given these representations, can the concept of space-time dilation be viewed as a form of space-time expansion in terms of their consequences?
