Document Summary
Distance that light travels in one year. Basic ideas of the theory of the big bang. All matter and energy concentrated in a single point (singularity) Different ways in which chemical elements were generated. Light elements (atomic numbers <6): big bang nucleosynthesis. Medium elements (atomic numbers 6-26): during the life of a star. Heavy elements (atomic numbers >26): during the death of a star. What the doppler effect is, and what it means in terms of the universe key evidence that the universe is expanding, because light from distant stars is red- shifted with respect to us object emitting energy (sound or light) Waves are going to be compressed in front of the moving object, and expand behind the moving object. Red shifted galaxies moving away (bigger wavelengths) Basic steps to the formation of a stony planet (like earth: planetesimals accumulate into a larger mass because of gravitational attraction, development of an irregular proto-planet.
