Cosmology (general knowledge): Which physicist is commonly credited in quiz literature as being responsible for the Big Bang Theory? Note: Options include an answer often cited in GK even though multiple scientists contributed historically. Choose the correct name.

Given data

• The prompt asks for the physicist credited (in common GK framing) with the Big Bang Theory.

Concept / ApproachWhile the modern hot Big Bang model draws on work by several scientists (notably Georges Lemaître), many GK sources credit George Gamow for developing and popularizing the theory and its nucleosynthesis implications.

Step-by-step reasoning• Among the options, Gamow is the customary quiz answer.• Einstein did foundational relativity; Penrose worked on singularities; Michael Skube is not associated with cosmology.

Common pitfalls

• Confusing historical origin (Lemaître) with the name typically expected in GK (Gamow).

Final AnswerGeorge Gamow.
