🌟 Light as an Electromagnetic Wave vs. Curvature Wave (PPC View)
Light has fascinated scientists for centuries. Modern physics describes light in two powerful ways: as an electromagnetic wave and, in the PPC (Pawan Upadhyay's Pressure–Curvature) Law of Gravity, as a phenomenon whose motion is governed by pressure-generated spacetime curvature.
These two views are not contradictory—they describe different aspects of the same reality.
🔌 1. Light as an Electromagnetic (EM) Wave
The electromagnetic nature of light was discovered by James Clerk Maxwell.
Key ideas:
Light consists of oscillating electric (E) and magnetic (B) fields
The fields are perpendicular to each other and to the direction of motion
Light does not require a medium
It travels through vacuum at a constant speed:
c = 299,792,458 m/s
What this explains:
Reflection, refraction, interference
Polarization
Radio waves, microwaves, visible light, X-rays, gamma rays
Communication technologies (radio, Wi-Fi, satellites)
👉 Conclusion:
Light is an electromagnetic wave in its internal structure and propagation.
🌌 2. Light as a Curvature-Guided Wave (PPC View)
The PPC Law of Gravity adds a gravitational interpretation.
In PPC:
Mass–energy creates gravitational pressure
Pressure creates spacetime curvature
Curvature determines the paths (geodesics) of matter and light
PPC insight:
Light is not gravity itself, but its motion is guided by curvature produced by gravitational pressure.
Thus, light behaves like a curvature-guided wave in gravitational fields.
🧠Important Clarification (Very Important)
🔹 Light itself is NOT a curvature wave
🔹 Light does NOT create curvature in the PPC sense
🔹 Light remains an electromagnetic wave
Instead:
Curvature acts on light, not the other way around.
So in PPC:
EM theory explains what light is
PPC gravity explains how gravity affects light
🔄 3. How the Two Views Work Together
EM View:
Describes the nature of light
Explains how light propagates
Governed by Maxwell’s equations
PPC Curvature View:
Describes the environment light travels through
Explains bending, delay, redshift
Governed by pressure-generated curvature
🌠4. Light Bending: The Perfect Example
EM theory alone:
Cannot explain why light bends near massive objects.
GR:
Says spacetime is curved.
PPC:
Explains why spacetime is curved:
Gravitational pressure bends spacetime, and light follows that curvature.
Thus, light appears to bend—not because it slows down locally—but because the geometry shaped by pressure changes its path.
⏱️ 5. Speed of Light in Both Views
Locally, the speed of light is always c
Gravity does not slow light directly
Apparent slowing is due to:
Time dilation
Curvature of spacetime
Pressure gradients (PPC interpretation)
Both EM theory and PPC fully respect this principle.
✨ Final Understanding
Light is an electromagnetic wave by nature
Light behaves like a curvature-guided wave in gravity
PPC gravity does not replace electromagnetism
PPC explains the gravitational environment in which EM waves travel
Final statement:
Light is electromagnetic in essence, and curvature-guided in motion.
PPC gravity explains the curvature; Maxwell explains the wave.
