Theories About The Beginning Of The Universe Pdf Universe Stars Discoveries in astronomy and physics suggest that the universe had a definite beginning. the big bang theory is the prevailing theory that describes the origin and evolution of the universe. it is considered to be our best theory of cosmology because it explains most experimental observations. first stars may have seeded the growth of supermassive black holes that formed in the hearts of galaxies and became the spectacular power sources of quasars. in short, the earliest stars made possible the emergence of the universe that we see to day—everything from galaxies and qua sars to planets and people. the dark ages.
1 Theories On The Origin Of The Universe Pdf Universe Big Bang The universe is the astrophysics. albert einstein discovered that the energy can be converted into the matter and vice versa. at the beginning of the universe, the vacuum energy converted to matter. inside the stars the energy turns into matter, that’s why they shine. equivalence between matter and energy e = mc2 quarks , leptons p n e. Once scientists understood that the universe was expanding, they immediately realized that it would have been smaller in the past. at some point in the past, the entire universe would have been a single point. this point, later called the big bang, was the beginning of the universe as we understand it today. First, the expansion of the universe, discovered by edwin p. hubble in the 1930s, as a recession of galaxies at a speed proportional to their distance from us. second, the relative abundance of light elements, explained by george gamow in. The expansion of the universe was one of the most important intellec tual discoveries of the 20th century, or of any century. it transformed the debate about whether the universe had a beginning: if galaxies are mov ing apart now, they must have been closer together in the past. if their.

In this unit we introduce the different theories on the origin, evolution, and future of the universe. the most prominent theories in this field are the big bang theory and the steady state theory. among them the big bang theory is the widely accepted one. hence it is given prominent place in the discussion.
