Steady State Theory & Oscillating Theory Flashcards
Another view that proposes that the universe has always been expanding
As the universe expands, new stars and galaxies are formed at the same rate that old ones become unobservable due to distance and recession velocity
Despite the continuous expansion, the average density of the universe remains the same
Has no beginning & end
Steady-state theory
Has always been here and will always be present
Steady-state theory
Always looks the same in any time and space
Steady-state theory
Created new matter as it continuously expands
Steady-state theory
They proposed the steady-state theory in 1948
Hermann Bondi
Thomas Gold
Fred Hoyle
Either created nor destroyed
Law of Conservation
It is not parallel with the law of conservation of energy and mass
Drawback of SST
The discovery of cosmic microwave background radiation significantly supported the explanations given by the big bang theory and led many scientists to reject the steady state theory in 1965
Drawback of SST
Recent finding reject the idea that cosmic radiation was a result of a supernova
Drawback of SST
Radiation is equal in any direction of the universe and could not have resulted from supernova
Drawback of SST
What is the other known name for Oscillating Universe Theory
Pulsating theory
The Universe is expanding and will contract one all the energy after the big bang has been used up. Then, it will expand again once it approached the point of singularity.
Oscillating Universe Theory
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
Big Crunch
A Caltech professor; called the birth of another universe as the BIG BOUNCE
Richard Tolman
The suggestion that the universe would collapse on its own after it reached its full expansion violates some current laws of physics, such as the postulated existence of dark energy.
Drawback of OUT
The currently postulated end of the universe is by big freeze or heat death
Drawback of OUT
