"Steady state".
The person who coined the term "big bang" meant it to be taken derisively; Sir Fred Hoyle was a proponent of the "steady state" theory of the cosmos, in which the universe had existed forever pretty much as it is now, and would continue forever.
But as evidence accumulated, the concept of a steady state universe began to be more and more untenable, and most astronomers and cosmologists now accept that the universe probably "began" at some point about 14 billion years ago. Some extremely exotic theories have bubbled up suggesting that the universe may be cyclical, that it may eventually collapse, or that it may continue to expand forever. These theories are still in flux, and are supported primarily by mathematical models rather than by observed facts.
But keep an open mind; we're only at the beginning of this story.

Scientists have proposed several theories of man's origin. Some of these theories are: the Creationist theory, the missing links theory and the out of Africa theory.
The larger scale theories generally fall into the category called Macro theories and they are generally considered to be concerned with social structures and the effects of those structures on the human behavior while Micro theories are considered to be theories and are concerned with trying to explain the individual level causes of crime and delinquency.
Theories of how planning should be done generally are often referred to as procedural planning theories. They are theories of planning while substantive theories are theories in planning.They are theories in specific fields.
The five theories of the state are the Pluralist theory, the Elite theory, the Marxist theory, the Functionalist theory, and the Systems theory. Each of these theories offers a different perspective on how power is distributed and how the state functions within a society.
Ancient Greeks had two major theories of matter. These were the Atomic theory of matter and the theory of pangenesis.
Interactionist theory is less tangible than role theory, because it involves internal mental models as opposed to external social models. The symbolic interaction perspective is also known as symbolic interactionism, it is a major framework of sociological theory.
