In current physics theories, gravity is expected to have a quantum nature, similar to other fundamental forces such as electromagnetism. However, reconciling gravity with quantum mechanics is still an open challenge, and a complete theory of quantum gravity has not yet been established.
The concept of a quantum value for gravity is associated with the hypothetical particle called the graviton, which is believed to be the quantum mediator of the gravitational force. In a fully realized theory of quantum gravity, it is expected that the graviton would carry discrete quanta of gravitational energy, much like photons carry discrete quanta of electromagnetic energy.
Regarding the maximum capacity of conjoined negative electrons, it's not clear what exactly you mean by "conjoined negative electrons." Electrons are fundamental particles with negative charge, and they do not have a notion of being "conjoined" in the same way that macroscopic objects can be. In quantum mechanics, electrons can be entangled or interact with each other, but the concept of a maximum capacity for conjoined negative electrons is not well-defined in the context of current scientific understanding.
As for the link between emergent effects and gravity, emergent phenomena in physics refer to properties or behaviors that arise from the collective interactions of many individual constituents. While emergent effects can be observed in various systems, such as condensed matter physics, they are not directly linked to gravity in a fundamental way.
Gravity, as described by general relativity, is associated with the curvature of spacetime caused by mass and energy. The emergent phenomena in other areas of physics, such as the behavior of complex systems or condensed matter physics, arise from the interplay of other fundamental forces and interactions, such as electromagnetic forces or quantum mechanical effects.
However, it is worth noting that there are ongoing investigations into possible connections between gravity and emergent phenomena in the context of quantum gravity and the holographic principle. These areas of research explore the idea that gravity may emerge from more fundamental quantum mechanical descriptions, leading to connections between gravity and emergent phenomena, but this is still an active area of study with many open questions.
