COSMOLOGY

• cosmology - It is a branch of astronomy that involves the origin and evolution of the universe, from the Big Bang to today and on into the future.
• universe - . It includes all of space, and all the matter and energy that space contains.
• big bang nucleosynthesis - The process that creates new atomic nuclei from pre-existing nucleons. Proton + Neutron = Deuterium Deuterium + Neutron = Tritium
• big bang nucleosynthesis - It forms the light elements.
• stellar explosion or supernova - Dramatic explosions that take place during the final stages of the stars. It forms elements heavier than Fe
• georges lemaitre - Who propose the theory of big bang theory.
• big bang theory - The idea that the universe began as just a single point , then expanded and stretch to grow as large as it is right now.
• singularity - A point in space and/or a moment in time where the universe was infinitely hot.
• inflation - A theory of exponential expansion of space in the early universe. Inflationary epoch lasted from 10-36 seconds.
• very hot , very dense and expanding - MAJOR TENETS OF THE BIG BANG THEORY
• molecular clouds - Dust clouds and gas clouds, referred to as
• gravitational energy - Energy that pulls the molecular clouds causing it to collapse.
• big bang nucleosynthesis - what is the first stage's of cosmic
• stellar formation and evolution - this is the second stage of the cosmic.
• stellar explosion or supernova - this is the last stage of cosmic.
