稳态状态学说(Steady State Theory)是20世纪中期提出的宇宙学模型,主张宇宙无始无终且通过持续物质创造维持稳态,但因其无法解释关键观测证据(如宇宙微波背景辐射)而被大爆炸理论取代。下文将从理论框架、历史背景、核心争议及科学影响等方面展开分析。 一、理论框架与核心假设 稳态理...
Quasi-steady state cosmology (QSS) was proposed in 1993 by , , and as a new incarnation of steady state ideas meant to explain additional features unaccounted for in the initial proposal. The theory suggests pockets of creation occurring over time within the universe, sometimes referred to as ...
By this time, thesteady state theoryof the universe had been largely abandoned.───到此时,宇宙稳态论大半已被扬弃。 Perhaps the best known was proposed in 1948, and called thesteady state theory.───也许最广为人知的理论是1948年所提出的稳态理论。

By 1917, theoretical calculations based on Einstein's field equations showed that the Universe had to be in either a state of expansion or contraction. By 1929, observations made by George Lemaitre (who proposed the Big Bang Theory) and Edwin Hubble (using the100-inch Hooker telescopeat theMou...
What is the steady-state theory? The steady state theory is a theory proposed by Fred Hoyle, Herman Bondi, and Thomas Gold in 1948. It suggests that the universe has no beginning and no end. It also explains that as the universe expands, there is a continuous creation of new stars and...
Steady-State Theory refers to a mathematical concept associated with stationary Markov processes, characterizing nonequilibrium steady states in terms of time irreversibility, breakdown of detailed balance, free energy dissipation, and positive entropy production rate.
