How does the big bang theory support the steady state theory?

Answer 1

The Big Bang theory imposes a limit on how far we may look out in space as well as in time.

Also, the Big Bang theory precludes the possibility of Earth being in any kind of privileged position (the cosmological principle).

In the Steady State model, it is theoretically possible for the universe to exist eternally unchanged.

Answer 2

Steady State theory was developed in 1948 by Sir Fred Hoyle (a brilliant astronomer), as an alternative Theory. It gained momentum in the 1950's and 60's, but quickly died out in the early 70's as more evidence emerged in favor of the Big Bang Theory. Ironically Fred Hoyle was the same scientist who coined the term "Big Bang," in a derogatory manner, while describing what scientists today now accept as the birth of our universe.

So what does it state: In simplistic terms, this model asserts that the general character of the universe is not changing over time (hence, a steady state). It propones the idea that the universe looks the same no matter the viewpoint and that the universe has always looked like this.

The Demise of Steady State

The Steady State theory offered simple solutions to the way the universe worked, but as observatories looked farther back into the early eras of the universe, astronomers started to see contradictions to the theory.

Astronomers found that the universe actually evolves over time. For example, cosmologists discovered different types of stars are more common during different ages of the universe. The final demise of the Steady State theory came in the late 1960's with the discovery of the Cosmic Microwave Background. Steady State Theory could offer no convincing explanation for the CMB and as such, most contemporary cosmologists feel this theory is wrong.

Answer 3

By creation theory I judge you mean Creationism. Creationism is not a theory it is a religious belief (arrived at by faith rather than science). Creationism takes several different forms. There isn't just one belief called Creationism. But, basically it is the belief that God made everything. Usually in its original form. That is, he made the components of the universe -- the galaxies, the stars, our sun our earth, etc. in the form they are today.

Classically Creationism is an argument against evolution. It says plants and animals did not evolve slowly form simpler forms or organisms, but were created in the form we see them today. Giraffes were made like they are today, they did not begin as deer like animals which slowly developed longer necks because the necks made them better equipped to survive.

The big bang is a scientific theory, supported by evidence, that suddenly at a point in the past there was an event where energy and matter suddenly formed, and after that, expanded and combined and changed into the things we see today.

Answer 4

The steady state theory is not now considered to be a realistic possibility.

The main difference is that the steady state theory proposes that matter

is being slowly created all the time instead of in one "big bang".

The continuous creation of matter is supposed to keep the density of the

Universe in a "steady state" as the Universe expands. That's why it's called

the steady state theory.

Answer 5

The big bang theory states that the universe started when an expansion of space at all points in our Universe. Thus, our Universe had a specific start date ("A day with no yesterday" is how George LeMaitre described it), and its mass density has been decreasing over time. The evidence for this viewpoint is pretty overwhelming.

The cause of this expansion is presently unknown. We can't look back before the big bang because the universe didn't exist then, and our present theoretical structure breaks down when space shrinks to this point.

The steady state theory says that the universe has always existed and it is growing at the same rate it has always been growing. As such, their is no start date for our Universe, and the matter density of our Universe has remained pretty much constant over all eternity.

Answer 6

The Steady State Theory, now considered untenable by almost everyone, was the dominant cosmological model for centuries. It was preferred by Einstein, at least in the early part of his life. It was unsettling for him when his theories of relativity were shown to point to other models. The Steady State Theory says that the universe existed for eternity past and will exist for eternity future, and that the various objects, including galaxies, are fixed in place and not moving relative to one another. For various reasons having to do with gravity, it can be shown that this 'steady state' would not be able to sustain itself and would result in unstable and chaotic conditions throughout the universe. The Steady State is refuted not by the Big Bang but by the direct observations of the stars and galaxies that indicate a great deal of movement of galaxies relative to one another. The Big Bang is a theoretical attempt to explain the movements of the galaxies that have been observed for decades. If galaxies are moving away from one another, then it is likely that in the past they were closer together. The farther back we extrapolate, the theory goes, the closer together everything was. Theoretically, at roughly 14 or 15 billion years in the past, everything was in one place. Strange? Indeed. Theories often are.

Answer 7

How much information do you need? and at what level of discourse; high school, college. or graduate?

Anyway, there are not many adherents to the 'steady-state' theory anymore. There's too much evidence in favor of the B-B.

AND the latest buzz is that it wasn't the Big Bang, but the Big Bounce. Yep, the universe existed before B-B and after its prior expansion, it collapsed under mutual gravitation and then started over. No one knows how many times this has occurred.!

Bounce theory has been put forward to account for 'dark' or 'negative' energy.

Answer 8

Big Bang Cosmology (BBC) has become (pretty much) universally accepted, with the Steady State Hypothesis now bordering on pseudo-science, simply because the observations predicted by the former are seen, and those predicted by the latter are not. It's the same reason a geo-centric solar system is no longer accepted.

Answer 9

The steady state hypothesis completely fails to explain the following:

1) existence, spectrum, and isotropy of the Cosmic Microwave Background Radiation.

2) the lack of any white dwarf stars older than about ten billion years.

3) the ratio of radiactive isotopes to their decay products; all showing a maximum age of about ten billion years.

4) no quasars close to us.

If our Universe has been steady for even the last twenty billion years, the last three things would not be seen -- but they are. If our Universe did not expand from a dense state about 13 billion years ago, we wouldn't see (1) -- but we do. Steady State Hypothesis is now on the fringes of cosmology, and is now almost a pseudo-science. To believe it is to pretty much reject science.

Answer 10

The Big Bang Theory and the revised Steady State Theory are similar in that they are both in compliance with the Cosmological Principle, which states that the universe is homogeneous and isotropic in Space and Time, and the concept of an expanding universe.

The Big Bang Theory and the revised Steady State Theory are different by virtue of their proposed models. The Big Bang supports interpreted observational evidence for an evolutionary expansion of the universe and rationalization for a finite age of the universe. The revised Steady State Theory promotes that new matter and energy are continuously created as the universe expands and the rationalization for an ageless universe.
