actinices
Actinices are a proposed class of hypothetical subatomic particles that would mediate a fifth fundamental force of nature. This force, sometimes referred to as the "fifth force" or "actinic force," is theorized to exist alongside the four known fundamental forces: gravity, electromagnetism, the strong nuclear force, and the weak nuclear force. The concept of actinices and their associated force arose from attempts to explain certain cosmological observations and anomalies in particle physics that cannot be fully accounted for by the Standard Model of particle physics.
The existence of actinices is not experimentally confirmed, and they remain a speculative concept within theoretical
Research into actinices is driven by the ongoing quest to understand the fundamental constituents of the universe
