Question
Who was the first to propose a specific model for the Big Bang?
- Group of answer choices:
- Stephen Hawking
- Georges Lemaitre
- Albert Einstein
- John Wheeler
Solution
The first person to propose a specific model for the Big Bang was Georges Lemaître. In the early 20th century, Lemaître, a Belgian priest and physicist, introduced the idea that the universe began from a "primeval atom" which exploded to form the universe we see today. His groundbreaking work laid the foundation for the Big Bang theory.
Stephen Hawking made significant contributions to cosmology, particularly regarding black holes and the nature of the universe, but he did not propose the initial Big Bang model. Albert Einstein contributed to the field of cosmology with his theory of general relativity, which provides the framework for understanding the universe's expansion, but he did not specifically propose the Big Bang. John Wheeler was influential in the development of theoretical physics but did not propose the Big Bang model itself.
Thus, the correct answer to your question is Georges Lemaître.
