Intuitive far reaching thought experimenting ancient sages of India hid many life changing knowledge modules in Upanishads. Probably rather intuitive quantum physics of modern science may show a bridge for us to advance !
Intuition and spontaneous visualisation of the ancient sages to understand who and why they came into existence …tried their best to convey their findings through Vedas and Upanishads to posterity .
I heard over 20 years scholars on Indian ancient texts . I am convinced in modern science Quantum physics , a part intuitive sçience , could give me tools to take advantage to advance our science. Dirac did accept this position ,
The Schrödinger equation is a fundamental equation in quantum mechanics that describes the behavior of quantum particles, such as electrons and photons. It's like the quantum equivalent of Newton's laws of motion in classical mechanics, but instead of predicting the exact path of a particle, it gives us information about the probability of finding the particle in a certain location at a certain time.
Key Concepts:
Wave Function (Ψ): This is a mathematical function that describes the quantum state of a particle. It contains all the information we can know about the particle.
Probability Density: The square of the wave function, |Ψ|^2, gives the probability of finding the particle at a specific location.
Quantum Superposition: A quantum particle can exist in multiple states simultaneously until it's measured.
Quantum Entanglement: Two particles can become linked, so that measuring one instantly affects the other, regardless of distance.
The Equation Itself:
The time-dependent Schrödinger equation is:
iħ(∂Ψ/∂t) = ĤΨ
Where:
i: The imaginary unit (√-1)
ħ: Reduced Planck's constant (h/2π)
∂Ψ/∂t: The partial derivative of the wave function with respect to time
Ĥ: The Hamiltonian operator, representing the total energy of the system
Ψ: The wave function
Understanding the Equation:
The left side represents the time evolution of the wave function.
The right side represents the total energy of the system acting on the wave function.
Interpreting the Solution:
Solving the Schrödinger equation for a specific system gives us the wave function. From the wave function, we can calculate probabilities of finding the particle in different states or locations.
Visualizing the Wave Function:
The wave function can be visualized as a wave, often represented as a complex number. The amplitude of the wave at a point represents the probability of finding the particle there.
Applications:
The Schrödinger equation is used to understand a wide range of phenomena, including:
The behavior of atoms and molecules
The properties of materials
The physics of semiconductors and lasers
Quantum computing
Limitations:
While the Schrödinger equation is incredibly powerful, it has limitations. It doesn't account for relativistic effects, which become important at high speeds. For a more complete description, the Dirac equation is used.
Additional Resources:
Remember:
Understanding the Schrödinger equation requires a solid foundation in mathematics, particularly calculus and linear algebra. It's a complex topic, but with patience and practice, you can gain a deeper understanding of this fundamental equation of quantum mechanics.
The Dirac equation is a relativistic wave equation that describes the behavior of spin-1/2 particles, such as electrons and positrons. It's a cornerstone of quantum mechanics and quantum field theory, providing a more accurate and complete description of the behavior of particles at high speeds compared to the Schrödinger equation.
Key Concepts:
* Relativistic Invariance: The Dirac equation is consistent with the principles of special relativity, meaning it remains valid in different reference frames moving at constant velocities.
* Spin: It naturally incorporates the concept of spin, an intrinsic angular momentum of particles that is not associated with classical rotation.
* Antiparticles: The equation predicts the existence of antiparticles, such as the positron, which is the antiparticle of the electron.
* Wave Function: The wave function in the Dirac equation is a four-component object called a Dirac spinor, which represents the particle's spin and its four possible states (spin up/down, particle/antiparticle).
The Equation Itself:
The Dirac equation is often written in a compact form using matrix notation:
(iħγμ∂μ - mc)ψ = 0
Where:
* i: The imaginary unit
* ħ: Reduced Planck's constant
* γμ: Dirac gamma matrices (4x4 matrices)
* ∂μ: Four-gradient operator (∂/∂t, ∂/∂x, ∂/∂y, ∂/∂z)
* m: Mass of the particle
* c: Speed of light
* ψ: Dirac spinor (four-component wave function)
Understanding the Equation:
* The equation combines the concepts of quantum mechanics and special relativity.
* The Dirac gamma matrices are essential for incorporating spin and relativistic invariance.
* The equation predicts the existence of negative energy solutions, which were interpreted by Dirac as representing antiparticles.
Applications:
The Dirac equation has numerous applications in physics, including:
* Describing the behavior of electrons in atoms and molecules
* Understanding the properties of materials
* Developing quantum field theories
* Exploring the nature of quantum electrodynamics (QED)
Limitations:
While the Dirac equation is a powerful tool, it doesn't fully account for the effects of gravity. It's also challenging to reconcile it with general relativity, leading to ongoing research in quantum gravity.

Remember:
The Dirac equation is a complex mathematical equation that requires a deep understanding of quantum mechanics and special relativity. It's a fundamental equation in modern physics, providing insights into the behavior of matter at the smallest scales.
Why not Dirac spinor incorporate gravity as 5 th component? Say Dirac gamma matrix (5x5) with Five -gradient operator ?
While a 5x5 Dirac matrix and a five-gradient operator might seem like a straightforward way to incorporate gravity into the Dirac equation, there are significant challenges and limitations to this approach:
* Mathematical Consistency: Extending the Dirac equation in this way doesn't naturally lead to a consistent and physically meaningful theory. The mathematical structure of general relativity, which describes gravity, is fundamentally different from that of special relativity, which the Dirac equation is based on.
* Physical Interpretation: Introducing an additional dimension to the Dirac spinor and gamma matrices would require a new physical interpretation, which is not immediately obvious. It's unclear what this additional component would represent in terms of the particle's properties.
* Quantum Gravity: The unification of quantum mechanics and general relativity, a theory of quantum gravity, is a major unsolved problem in physics. While this approach might seem like a simple solution, it doesn't address the fundamental issues that arise when trying to quantize gravity.
Instead of modifying the Dirac equation directly, physicists have explored other approaches to incorporate gravity into quantum field theory, such as:
* Minimal Coupling: This approach involves coupling the Dirac equation to the gravitational field through the covariant derivative. This method is widely used and provides a good approximation for weak gravitational fields.
* Quantum Field Theory in Curved Spacetime: This framework allows for the study of quantum fields in curved spacetime backgrounds, providing a more rigorous and general approach to incorporating gravity.
* String Theory and Loop Quantum Gravity: These theories offer promising avenues for unifying quantum mechanics and general relativity, but they are highly complex and still under development.
While the idea of extending the Dirac equation with an additional dimension is intriguing, it's important to consider the mathematical and physical challenges involved. Currently, the most promising approaches to incorporating gravity into quantum field theory involve more sophisticated techniques that address the fundamental issues of quantum gravity.

So photons moving across the dvarios spaces subject to again four types of gravitational quantum fields??
Answer
The concept you've described, involving multiple levels of gravitational forces and a cyclical universe, is an interesting blend of ancient Indian philosophy and modern physics. While there are intriguing parallels between the two, it's important to approach such ideas with a critical eye and consider the limitations of both ancient and modern knowledge.
Ancient Indian Cosmology:
Ancient Indian texts, such as the Vedas and Puranas, describe a cyclical universe undergoing creation, sustenance, and destruction. The concept of "Shsha" or the remainder, which sustains the universe during its dissolution, is fascinating. However, it's important to note that these texts often use symbolic and metaphorical language to convey profound spiritual and philosophical truths, rather than providing a literal scientific explanation of the universe.
Modern Physics:
Modern physics, on the other hand, has developed sophisticated theories like general relativity and quantum mechanics to explain the nature of gravity and the universe. While these theories have made remarkable progress, they still have limitations and unanswered questions.
Reconciling Ancient and Modern Perspectives:
Reconciling the ancient Indian concept of multiple levels of gravitational forces with modern physics is a complex task. While there are some similarities, such as the idea of gravity as a fundamental force, there are also significant differences in the underlying principles and mathematical frameworks.
Photon's Journey Through Gravitational Fields:
Photons, as massless particles, are not directly affected by gravity in the same way as massive objects. However, they can be influenced by the curvature of spacetime caused by massive objects. This curvature can bend the path of photons, leading to phenomena like gravitational lensing.
A Cautious Approach:
While it's fascinating to explore the connections between ancient wisdom and modern science, it's essential to approach such comparisons with caution. Ancient texts often use metaphorical language and may not provide a literal scientific explanation. Modern physics, while powerful, is still evolving and has its own limitations.
Further Exploration:
If you're interested in delving deeper into this topic, I recommend exploring the following:
* Ancient Indian Texts: The Vedas, Upanishads, and Puranas offer rich insights into ancient Indian cosmology and philosophy.
* Modern Physics: Study general relativity and quantum mechanics to understand the modern scientific understanding of gravity and the universe.
* Philosophical Discussions: Engage in philosophical discussions with experts in both ancient Indian philosophy and modern physics to gain different perspectives.
By combining the wisdom of the past with the knowledge of the present, we can continue to explore the mysteries of the universe and deepen our understanding of the interconnectedness of all things.
