Formulation of the Big Bang Theory
Introduction to the Big Bang Theory
The Big Bang theory is a cornerstone of modern cosmology, describing the origin and evolution of the universe. It posits that the universe began from an extremely hot and dense state and has been expanding ever since. This theory has undergone significant development and refinement over the past century.
Early Contributions and Conceptual Foundations
Unorthodox Cosmologists: Darwin, Poe, and Spencer
Before the formalization of the Big Bang theory, several unorthodox cosmologists in the 18th and 19th centuries, including Erasmus Darwin, Edgar Allan Poe, and Herbert Spencer, anticipated some of its key elements. Although their ideas were not framed within the discipline of mathematical physics, their conceptual models contributed to the evolving understanding of cosmology as an evolutionary science .
Einstein's Static Universe and Subsequent Developments
The groundwork for the Big Bang theory was laid by Albert Einstein's attempt to model a static universe using his general theory of relativity. This model was further developed by Alexander Friedmann and Georges Lemaître, who introduced the concept of a dynamic, expanding universe. Lemaître, in particular, is credited with formulating the idea of a "primeval atom" or "cosmic egg" that marked the beginning of the universe .
Key Figures in the Development of the Big Bang Theory
Georges Lemaître: The Primeval Atom
Georges Lemaître, a Belgian priest and physicist, is widely recognized for his pivotal role in formulating the Big Bang theory. In the early 1930s, Lemaître proposed that the universe began from a single, extremely dense point, which he referred to as the "primeval atom" Landa2014Alpher2017.
George Gamow and the Hot, Dense Universe
Physicist George Gamow made significant contributions to the Big Bang theory by introducing the concept of a hot, dense early universe. In 1946, Gamow, along with his colleagues Ralph Alpher and Robert Herman, developed the idea of nucleosynthesis, explaining how elements were formed in the early universe. They also predicted the existence of cosmic microwave background radiation, a crucial piece of evidence for the Big Bang theory Bagdonas2021Alpher2017.
Popularization and Acceptance
Fred Hoyle and the Term "Big Bang"
The term "Big Bang" was coined by British astrophysicist Fred Hoyle during a radio broadcast in 1949. Hoyle, a proponent of the rival steady state theory, used the term derisively. Despite his intentions, the name stuck and became widely accepted in both scientific and popular discourse .
Observational Evidence and Theoretical Refinement
The Big Bang theory gained substantial support through observational evidence, such as Edwin Hubble's discovery of the expanding universe and the cosmic microwave background radiation. These findings, along with the theoretical work of many scientists, solidified the Big Bang model as the leading explanation for the origin and evolution of the universe .
Conclusion
The formulation of the Big Bang theory was a collaborative effort involving many scientists over several decades. While Georges Lemaître is often credited with its initial formulation, significant contributions from figures like George Gamow and observational evidence from astronomers like Edwin Hubble were crucial in developing and validating the theory. The Big Bang theory remains a fundamental framework for understanding the universe's origins and its ongoing evolution.

El Big Bang antes del Big Bang — según Spencer, Darwin y Poe (The Big Bang before the Big Bang — in Spencer, Darwin, and Poe)
Heterodox cosmologists from the 18th and 19th centuries (Erasmus Darwin, Edgar Allan Poe, and Herbert Spencer) predicted some of the major outlines of the Big Bang theory, allowing for the re-conceptualization of cosmology and physics as evolutionary sciences.

THE BIG BANG NEVER HAPPENED
The big bang theory is challenged by a plasma universe, which is too large to have been created from a single explosion 20 billion years ago, and instead grows slowly in giant strands connecting the smallest particles of matter to an infinity of different cosmic systems.
