Document Summary
The universe was in nitely small and hot and evolved by expanding fairly rapidly. The whole of the universe was compressed into this small volume. We evolved through a period of quick evolution (the rst few fractions of a second). This period of rapid expansion was less than a second long. Matter was soon visible (though it was really hot). We would not be here if matter had no won the battle between matter vs anti-matter. As the universe expanded, the particles should be moving further apart. The doppler effect: this question can be addressed by understanding the doppler effect. The train"s pitch increases as it moves toward you and decreases as it moves away. The distribution of pattern of sound shows that the sound waves are further apart away from the sound source and the sound waves are closer together next to the sound source.
