zeromass

Zeromass refers to a theoretical concept in particle physics and cosmology that describes a hypothetical state where matter and antimatter annihilate each other completely, resulting in no residual mass. This term is often explored in the context of understanding the early universe, particularly the asymmetry between matter and antimatter observed today.

In the early moments after the Big Bang, the universe was believed to contain nearly equal amounts of matter and antimatter. When these particles meet, they annihilate, converting their mass entirely into energy in the form of gamma rays, according to Einstein’s mass-energy equivalence principle (E=mc²). However, the current universe appears to be composed almost entirely of matter, with very little detectable antimatter. This discrepancy is known as the matter-antimatter asymmetry problem, and zeromass represents an extreme theoretical scenario where this imbalance might have been resolved through complete annihilation.

Some theoretical models speculate that regions of the universe where such complete annihilation occurred could have formed voids or "bubbles" devoid of matter. These areas would have zero net mass, hence the term "zeromass." Such regions might explain certain large-scale cosmic structures, like underdense voids observed in galaxy surveys, though no direct evidence of zeromass regions has been confirmed.

Zeromass is also discussed in the context of exotic physics, such as certain interpretations of dark energy or modified gravity theories. In these scenarios, regions with zero effective mass could influence cosmic dynamics in unconventional ways. However, zeromass remains largely speculative and is not part of mainstream cosmological models.

Further study in particle physics, particularly experiments like those conducted at the Large Hadron Collider, may provide insights into the behavior of matter and antimatter, potentially clarifying whether zeromass phenomena play a role in the universe’s evolution.
