• Anticipation — The act of anticipating and its result; the intuition, foreseeing, or execution of an event, idea, or action before the proper time or before a due date. In literature (science fiction), the term defines the genre that projects the future evolution of society and technology based on scientific speculations made in the present.
• Anticipation — The act of anticipating; a mental representation, intuition, or execution of a fact before its natural time or before a due date. In literature, the term denotes the science-fiction genre that explores and projects the future of humanity, technological evolution, and social transformations based on current scientific data and theories.
• Antigravity — A hypothetical phenomenon consisting of the cancellation, inversion, or neutralization of the gravitational attraction force exerted by a massive body; gravitational repulsion. In modern theoretical physics, the concept is analyzed in relation to dark energy or negative mass hypotheses.
• Anti-universe — A hypothetical universe composed entirely of antimatter (antiparticles such as antiprotons, antineutrons, and positrons), representing an inverted physical and structural duplicate of our material universe. In advanced quantum mechanics theories and science fiction literature, a potential direct contact between our universe and this anti-universe would instantly lead to total annihilation, converting the entire mass into pure energy.
• Anti-utopia — A literary, philosophical, or cinematic manifestation (often synonymous with dystopia) depicting an imaginary future society organized under extreme totalitarian, oppressive, or technocratic principles, representing the absolute antithesis of an ideal utopia. This conceptual genre analyzes individual dehumanization, the loss of fundamental liberties, and the absolute control exerted by an oppressive state apparatus following social, technological, or political catastrophes.
• Asimov — The surname of the famous American writer and biochemist of Russian origin Isaac Asimov (1920–1992), one of the most influential authors of science fiction and popular science of the 20th century. Structurally, his name is globally associated with the creation of the 'Three Laws of Robotics', the 'Foundation' series, and a visionary outlook on artificial intelligence and humanity's future.
• To land on the Sun — To perform a smooth descent and controlled landing of a spacecraft, exploration module, or cosmic probe onto the surface of the Sun or within a theoretical zone extremely close to the solar atmosphere; the term is used exclusively in sci-fi literature or speculative theoretical studies, built by analogy with verbs like 'aseleniza' or 'ateriza'.
• Solar landing — The act of landing on the Sun; a hypothetical descent and settling of a cosmic vehicle onto the surface of the Sun. This linguistic term extends the class of technical landing nouns (aterizare, amartizare, aselenizare), used primarily in sci-fi jargon or modern semantic exercises.
