Creation Of The Universe And Theories Flashcards
Is a cosmological model that explains how the universe began
Suggest that the universe started its expansion 13.8 billion years ago
Not a literal explosion
big bang theory
Matter dilutes as the universe expands
Raisin bread model big bang theory
Predicted to be the core of a black hole high temp and density
Intense heat resulted to formation of matter and antimatter particles were destroyed every time they collided with each other
SINGULARITY
Is the formation of elements, presence of these elements led to the formation of stars and galaxies
Led to plantes comets and asteroids
NUCLEOSYNTHESIS
Proposes that the universe has always been expanding
New stars and galaxies formed at the same rate old ones become un observable due to distance and recession velocity
THE STEADY STATE THEORY
Matter is constantly created as the universe expands
Steady State Theory
Matter is constantly created as the universe expands
Steady State Theory
Proponents of the steady state theory
Hermann Bondi (1919-2005)
Thomas Gold (1920-2004)
Fred Hoyle (1915-2001)
Also known as the Pulsating Theory
Proposes that the universe is explaining and will contract once all the energy of the big bang has been used up
Will expand again once approaches point of singularity
OSCILLATING UNIVERSE THEORY
Is a combination of big crunch and big bang
Oscillating universe theory
Occurs when the universe expands and eventually reverses, then collapses causing the formation of a singularity results to big bang and new universe
THE BIG CRUNCH
Proponent ofnoscillating universe theory
Richard Tolman(1881-1948)
According to this theory the solar system originated from a nebula
Was widely accepted view of formation of the solar system some 4.5 billion years ago
THE NEBULAR THEORY
Proponent of the nebular theory
Immanuel Kant
Proposes that the planets were formed from the material ejected from the sun during and encounter with another celestial object such as another statt
THE ENCOUNTER THEORY
