what is the meaning of steady state theory
Steady State theory In cosmology, the Steady State theory is an alternative to the Big Bang model of the evolution of the universe. In the steady-state theory, the density of matter in the expanding universe remains unchanged due to a continuous creation of matter, thus adhering to the perfect cosmological principle, a principle that asserts that the observable universe is basically the same at any time as well as at any place.

Commonwealth (U.S. state) The term "Commonwealth" does not describe or provide for any specific political status or legal relationship when used by a state.[8] Those that do use it are equal to those that do not. A traditional English term for a political community founded for the common good, it is used symbolically to emphasize that these states have a "government based on the common consent of the people"[9] as opposed to one legitimized through their earlier colonial status that was derived from the British crown. It refers to the common "wealth", or welfare, of the public[10] and is derived from a loose translation of the Latin term res publica.[a]
