What is 'Pulsating theory' and 'Steady state theory'?
Pulsating Theory According to this theory, the universe is supposed to be expanding and contracting alternately i.e. pulsating. At present, the universe is expanding. According to pulsating theory, it is possible that at a certain time, the expansion of the universe may be stopped by the gravitational pull and the may contract again. After it has been contracted to a certain size, explosion again occurs and the universe will start expanding. The alternate expansion and contraction of the universe give rise to pulsating universe.
How long has the universe existed going by the Steady State Theory?
The steady-state theory is obsolete - it is now known that the Universe does change over time (the Steady-State Theory states that it doesn't). According to the Steady-State Theory, the Universe has no beginning and no end.
How did Einstein's theory change people's view of the universe?
Einstein's theory of relativity revolutionized people's view of the universe by introducing the concepts of space-time curvature, time dilation, and the interrelationship of mass and energy. It showed that gravity is not just a force acting at a distance, but a bending of space itself. This new understanding fundamentally shifted our perception of how the universe works and our place within it.
Which theory proposes that all the matter in the universe simply exploded outward after it was compressed into a small space under tremendous pressure?
The big bang theory does not state that "the universe began with a gigantic explosion." The theory suggests that our universe originated from an infinitesimally small point called a singularity. Since all of space was all localized within this point, the rapid expansion of the universe isn't an explosion. An explosion occurs within space, but the expansion of space itself isn't an explosion. Quite simply, there isn't anything outside of space for the universe to explode into. Thus the "big bang" wasn't big, nor did it go bang. Around the time of the big bang (about 13.7 billion years ago), the universe was much hotter and expanding very rapidly (somewhat analogous to an explosion but by no means an actual explosion).
What is the evolution theory of the creation of the universe?
Evolution does not concern the origin of the universe. Evolution is a theory concerning the origin of species--diverse biological organisms--via mechanisms of inheritance with modification. The origin of the universe is best dealt with by the Big Bang theory.
What is the dust theory and how does it explain the formation of celestial bodies in the universe?
The dust theory proposes that celestial bodies in the universe form from clouds of dust and gas. Over time, gravity causes these particles to come together and clump, eventually forming planets, stars, and other objects in space.

What is the description of the no boundary universe theory?
It is very easy to answer- First, I want to tell that , what is a universe? A universe is a limitless space with billion of stars in it. So,lets come to the point.There is no boundary in the universe as it is a very vast space and billion of other universe are also there. I wish that you could understand it
What is static universe theory?
from CosmologyScience.com "Dynamically stable, non-expanding or non-stretching Universe models; space does not 'expand' with these models." "Do not confuse with Steady-state models which employ space expansion." For more details see -- http://www.cosmologyscience.com/glossary.htm#Static
What theory proposes species evolve during short periods of rapid change?
Punctuated equilibrium theory proposes that species evolve rapidly during short periods of significant change, followed by long periods of stability with little evolutionary change. This contrasts with gradualism, which suggests that evolution occurs steadily over long periods of time.
How long has the universe existed going by the Steady State Theory?
The steady-state theory is obsolete - it is now known that the Universe does change over time (the Steady-State Theory states that it doesn't). According to the Steady-State Theory, the Universe has no beginning and no end.
What is the significance of the Kaluza-Klein theory in the field of theoretical physics?
The Kaluza-Klein theory is significant in theoretical physics because it proposes that the universe may have extra dimensions beyond the familiar three spatial dimensions and one time dimension. This theory has influenced the development of modern theories like string theory and has provided new insights into the fundamental forces of nature.
The theory that evolution occurs during short periods of rapid change is puntuated?
The theory that evolution occurs during short periods of rapid change is punctuated equilibrium. This theory suggests that most species remain relatively unchanged for long periods, with bursts of significant change happening over short periods of time. This contrasts with the gradualism theory, which proposes that evolution occurs at a slow and constant rate.
Which best describes the beginning of big bang theory?
The Big Bang Theory is a scientific theory that suggests the universe began as a singularity around 13.8 billion years ago. It proposes that the universe expanded rapidly from a hot, dense state, cooling over time to form stars, galaxies, and eventually planets. This theory is supported by various observations and evidence in the fields of cosmology and astrophysics.
A theory about how species can change over time?
The theory of evolution proposes that species can change over time through processes like natural selection, genetic drift, and mutations. These mechanisms drive variation within populations, allowing those individuals with advantageous traits to survive and reproduce, resulting in changes in the species over successive generations.
How did Einstein's theory change people's view of the universe?
Einstein's theory of relativity revolutionized people's view of the universe by introducing the concepts of space-time curvature, time dilation, and the interrelationship of mass and energy. It showed that gravity is not just a force acting at a distance, but a bending of space itself. This new understanding fundamentally shifted our perception of how the universe works and our place within it.
How would you describe the punctuated equilibrium theory?
The punctuated equilibrium theory suggests that evolution occurs in rapid bursts of change interspersed with long periods of stasis. It proposes that species experience sudden bursts of evolutionary change due to localized environmental pressures, followed by extended periods of little to no change. This theory contrasts with the gradualism model, which suggests a constant and gradual rate of evolution over time.
