Flawed relativistic time can't challenge abstract time:
21 January 2024
By Soumendra Nath Thakur.
There is always a recognized place for scientists, but the science they discover or theorize is the main consideration, because science is about advancing scientific understanding and not the place of scientists.
I need to point out that it was relativity that challenged Newtonian time and promoted relativistic spacetime but it is now certain that the promotion of relativistic time and therefore spacetime is a flawed proposition. Whereas relativistic spacetime is based on Einstein's own definition of time and space as spacetime but it is now certain that Einstein's time like relativity is a flawed representation of time and therefore relativity is based on a flawed interpretation of spacetime that cannot be fully repaired. .
On the other hand Newtonian abstract time is still meaningful in all scientific applications. This means that abstract time can still be considered applicable for all scientific and applied purposes whereas Einstein's relativistic time is flawed given its imposed natural aspects. Clearly time is not natural.
In fact, the relativistic misrepresentation of time is very likely to shake the rest of the relativistic foundations because they are based on the misrecognition of time, hence spacetime, where Newtonian time is applied by Earth's space agency with flying colours for all applicable purposes.
Therefore, science is more relevant here than the places occupied by scientists.

The Planck Length and the Constancy of Light Speed: Navigating Quantum Gravity's Enigma and the Limits of Physical Theories
Summary:
The exploration of the Planck length and the constancy of light speed is central to understanding quantum gravity and the limitations of current physical theories. The Planck length, derived from fundamental constants, signifies a scale in general relativity where quantum effects become significant. Quantum gravity, aiming to reconcile quantum mechanics and general relativity, involves the Planck length as a crucial parameter, suggesting quantum properties in spacetime at small scales. The constancy of light speed, foundational in relativity, particularly in quantum gravity's context, lacks a complete explanation. The challenges at small scales underscore the need for theories like string theory and loop quantum gravity. Max Planck proposed Planck units, including the Planck length, in 1899-1900, but the explicit link to the constancy of light speed, a postulate in Einstein's 1905 special relativity, came later, shaping our profound understanding of spacetime.
Description:
The relationship between the Planck length and the constancy of the speed of light plays a role in the broader context of quantum gravity and the limitations of current physical theories. Let's elaborate on the consequences:
Range of Validity of General Relativity:
The Planck length (ℓP) is a fundamental length scale that emerges from combining the constants G (gravitational constant), ℏ (Planck's constant), and c (speed of light) in a specific way.
In the framework of general relativity, the Planck length represents a scale at which quantum effects become significant in the gravitational field. Beyond this scale, classical descriptions of spacetime provided by general relativity may no longer be valid, and a theory of quantum gravity might be needed.
Quantum Gravity and Planck Scale:
Quantum gravity is a theoretical framework that seeks to reconcile general relativity with quantum mechanics, especially in extreme conditions like those near black holes or at the very early moments of the universe.
The Planck length is a crucial parameter in theories of quantum gravity, where spacetime itself is expected to exhibit quantum properties at scales on the order of ℓP.
Unexplained Constancy of Light Speed:
While the constancy of the speed of light (c) is a foundational postulate in both special and general relativity, the reasons for this constancy within the broader context of quantum gravity, where the Planck length becomes significant, remain an open question.
There is no widely accepted theory that provides a complete explanation for the constancy of the speed of light within the framework of quantum gravity. Bridging the gap between general relativity and quantum mechanics at the Planck scale is an active area of research, and various approaches, including string theory and loop quantum gravity, aim to address these fundamental questions.
The consequences highlight the challenges and open questions at the intersection of quantum mechanics, general relativity, and the nature of spacetime at extremely small scales. The Planck length sets a fundamental scale at which these questions become prominent, and exploring quantum gravity theories is crucial for understanding the behaviour of physical phenomena in these extreme conditions.
Planck's Proposal (1899-1900):
Max Planck proposed the Planck units, including the Planck length (ℓP), in 1899-1900. These units were derived from fundamental physical constants, including Planck's constant (h), the speed of light (c), and the gravitational constant (G).
While Planck introduced these units, including c, in the context of developing a system of natural units, the constancy of the speed of light was not explicitly linked to its postulate in special relativity at that time.
Einstein's Special Relativity (1905):
Albert Einstein formulated special relativity in 1905. One of the postulates of special relativity is the constancy of the speed of light (c) in a vacuum.
Einstein's work on special relativity provided a new framework for understanding the behaviour of space and time, and it explicitly introduced the postulate of the constant speed of light.
Planck introduced the Planck units, including c, in 1899-1900, the specific postulate of the constancy of the speed of light in a vacuum (c) was formulated by Albert Einstein in 1905 as part of his theory of special relativity. The constancy of the speed of light in special relativity is a key feature that has profound implications for our understanding of spacetime, and it was introduced as a specific postulate by Einstein in 1905.

Applying the equations to a practical example, such as an "effective mass" (mᵉᶠᶠ) of 0.001 kg:
- E = mᵉᶠᶠc²
Concluding that relativistic mass (m') as an effective mass (mᵉᶠᶠ) of a relativistic energy E = [m₀/√{1 - (v²/c²)}]c² - m₀c².
Relativistic Mass and Energy Equivalence: Energetic Form of Relativistic Mass in Special Relativity:
E = m₀c²
m′ = m₀/√{1 - (v²/c²)} - m₀
mᵉᶠᶠ = m′
E = [m₀/√{1 - (v²/c²)}]c² - m₀c²
