Definition of Axion-Like Particles (ALPs) Axion-like particles (ALPs) are hypothetical elementary particles that extend the concept of the axion, originally proposed to solve specific problems in particle physics. These particles are characterized by their extremely low mass and weak interactions with ordinary matter, making them prime candidates in the search for dark matter. ALPs are […]
Definition of Supersolids Supersolids represent a unique phase of matter that intriguingly combines the rigid, ordered structure of a solid with the frictionless flow characteristic of superfluids. Unlike conventional solids, which maintain a fixed shape due to tightly bound atoms or molecules, supersolids exhibit the ability to flow without viscosity while preserving their crystalline lattice. […]
Definition of Majorana Neutrinos Majorana neutrinos are a hypothesized type of neutrino proposed by physicist Ettore Majorana in 1937. Unlike conventional neutrinos, which are distinct from their antiparticles, Majorana neutrinos are theorized to be their own antiparticles. This unique property challenges existing notions of particle-antiparticle symmetry and has profound implications for particle physics and cosmology. […]
Definition of Dark Energy Dark energy is a fundamental yet enigmatic component of the universe, playing a crucial role in modern cosmology. It is an invisible form of energy that permeates all of space and is responsible for the accelerated expansion of the cosmos. Despite its pervasive presence, dark energy remains largely mysterious, influencing the […]
Definition of the Cyclic Universe The cyclic universe is a cosmological model proposing that the cosmos undergoes an endless sequence of phases involving creation, evolution, destruction, and rebirth. Unlike linear models that envision a singular beginning and end, this concept suggests a perpetual loop where each cosmic era gives rise to the next, forming a […]
Definition of Cosmic Microwave Background Radiation The cosmic microwave background radiation (CMB) is a faint, pervasive electromagnetic radiation that fills the universe, serving as a relic from the early cosmos. It represents the thermal remnant from approximately 380,000 years after the Big Bang, marking the epoch when photons decoupled from matter, allowing light to travel […]
Definition of the Universe’s Age The age of the universe refers to the total time elapsed since the origin of all space, matter, and time itself. It represents the duration from the initial event known as the Big Bang to the present moment. Determining this age is a fundamental pursuit in cosmology, intertwining observational data, […]
Understanding Dark Matter Dark matter is a mysterious component of the universe, accounting for roughly 27% of its total mass-energy content. Unlike ordinary matter, it neither emits nor absorbs light, making it invisible to traditional telescopes and detectors. Its presence is inferred primarily through gravitational effects on visible matter, radiation, and the large-scale structure of […]
Definition of Dark Energy Dark energy is a mysterious form of energy that permeates all of space and is believed to be responsible for the accelerated expansion of the universe. It constitutes roughly 68% of the total energy content of the cosmos, making it a dominant component in modern cosmological models. Despite its prevalence, dark […]
Definition of Bose Glass The Bose glass represents a unique phase of matter observed in bosonic systems subjected to disorder. It emerges when bosons-particles that follow Bose-Einstein statistics-become localized due to random potential fluctuations, disrupting their ability to form a coherent superfluid state. This phase is distinguished by the coexistence of localized, insulating regions and […]
