American physicist who proposed the model of the Big Bang universe.

Big bang cosmology is an influential theory in modern cosmology, so who is the American physicist who put forward the big bang cosmology model?

1, 1940s. Gamov, an American Russian astrophysicist, first integrated general relativity into the theory of the universe and put forward the hot Big Bang cosmology.

2. 1929. American astronomer Hubble accidentally discovered in a study that most galaxies outside the milky way are gradually moving away from the milky way where the earth is located. From this, he further inferred that the universe is gradually expanding and the distance between galaxies in the universe is getting farther and farther. 1932, Belgian astronomer Lemaistre put forward the modern big bang theory for the first time: the whole universe first gathered in a "primitive atom", and then the big bang happened, and the fragments scattered in all directions, forming the present universe.

3. In the 1940s. Gamov, an American Russian astrophysicist, first integrated general relativity into the theory of the universe and put forward BIGBANG's cosmology model. In 1960s, penzias and Wilson discovered the cosmic background radiation, and later they confirmed that the cosmic background radiation was a relic left by the Big Bang, thus providing an important basis for the Big Bang theory.

The above is about the American physicist who proposed the big bang universe model.
