Who proposed the Big Bang Theory? Who discovered radioactive isotopes? What scientists contributed to the atomic model? Who created the Bohr model? Who discovered the quantum theory of how electrons move? Who discovered chemical reactions?
The idea that stars fuse together the atoms of light elements was first proposed in the 1920s, byEinstein's strong supporter Arthur Eddington. However, the real credit for developing it into a coherent theory is given to Fred Hoyle's work in the aftermath of World War II. Who discovered n...

For example, there have only been 1026 nanoseconds since the Big Bang. There are thought to be only 1075 atoms in the entire universe. When you consider that the Milky Way galaxy contains billions of suns, and there are billions of galaxies, you can see that that's a whole lot of ...
