Introduction
The idea that empty space could emit photons, leading to the generation of negative mass, is intriguing and has profound implications for both theoretical physics and potential technological applications. Here, we explore the theoretical framework for this concept, combining principles from General Relativity and Quantum Field Theory.
Conceptual Basis
If empty space somehow emits photons, we hypothesize that the energy required for this emission is drawn from the vacuum itself. According to the principles of energy conservation and Einstein’s theories, this process could result in a region of negative energy density, effectively behaving as negative mass.
Key Idea
The core idea of my hypothesis is that photon emission from quantum vacuum fluctuations can lead to the generation of negative mass and energy density, particularly in curved spacetime. This concept integrates principles from both Quantum Field Theory (QFT), General Relativity (GR), and Special Relativity (SR). Key Points
Photon Emission from Vacuum Fluctuations: According to QFT, the vacuum is not truly empty but filled with fluctuating fields. Under certain conditions, these fluctuations can produce real photons. Energy Conservation and Negative Energy Density: The energy required for photon emission is drawn from the vacuum itself (SR). This process could result in regions of negative energy density, effectively behaving as negative mass according to GR. Antigravity Effects: Negative energy density regions could exhibit repulsive gravitational effects, analogous to negative mass, challenging traditional models and suggesting new phenomena.

Please I need your valuable feedback, so that I can decide whether or not research this one further.
``Empty'' space(time) is ambiguous, there's flat space(time) and curved space(time). Flat spacetime definitely can't emit photons, however curved spacetime can. This doesn't imply antigravity, however, because these photons are matter particles, that don't change the spacetime geometry, they propagate on it.
Antigravity would require spin-1 particles (that aren't photons, not all massless, spin-1 particles are photons) that are part of the geometry-this would be possible were supergravity to describe spacetime geometry,cf. https://inspirehep.net/literature/142417
Nature of Spacetime
Photon Emission in Quantum Field Theory
Quantum Field Theory suggests that even in flat spacetime, the vacuum is not truly empty but filled with virtual particles and fluctuations. These fluctuations can, under certain conditions, lead to the emission of real photons:
- Casimir Effect: Demonstrates that vacuum fluctuations can produce measurable forces, indicating the potential for energy extraction from the vacuum.
- Unruh Effect: Suggests that an accelerating observer in flat spacetime can detect particles, implying that the vacuum state is observer-dependent.
Energy Conservation and Negative Energy Density
The counter-argument states that photons do not alter spacetime geometry and therefore cannot lead to negative mass. However, the hypothesis hinges on the idea of energy conservation and the nature of vacuum energy:
Photons and Spacetime Geometry
While photons themselves do not alter spacetime geometry, the hypothesis does not rely solely on the photons' properties but on the process of their emission and the resulting energy dynamics:
- Vacuum Energy Transformation: The transformation of vacuum energy into photons implies a change in the vacuum state. This change can lead to regions of negative energy density.
- Negative Mass Effects: Regions of negative energy density would exhibit effects similar to negative mass, such as repulsive gravitational effects.
Supergravity and Spin-1 Particles
The counter-argument suggests that antigravity effects require spin-1 particles that are part of the spacetime geometry, as in supergravity:
- Broader Framework: While supergravity provides a framework for such particles, the hypothesis does not exclude the possibility that similar effects could arise from more conventional interactions between QFT and GR.
- Exploratory Nature: The hypothesis encourages exploration beyond traditional models, potentially leading to new insights into the interplay between quantum mechanics and gravity.
