the pulsating universe theory is when the universe expands (the big bang) then contracts (the big crunch) and so on (it's pulsating). according to this theory right now the universe is expanding, but then it will contract

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.


Problems in the Pulsating Universe Theory?

Some potential problems with the Pulsating Universe Theory include lack of observational evidence, difficulty in reconciling with current understanding of cosmology, and challenges in providing a mechanism for the pulsations. The theory also faces criticisms regarding energy conservation and the feasibility of a cyclic universe model.


How does expanding universe provide evidence for big bang theory?

It is not so much that the universe is expanding, but rather the rationalization for its expansion that provides evidence to support the Big Bang Theory. The Big Bang supports interpreted observational evidence of the Cosmic Microwave Background Radiation (CMBR) barrier that there is an evolutionary expansion of the universe which promotes a finite age for the universe.


Is pulsating theory and oscillating theory the same?

Pulsating theory and oscillating theory are related concepts in cosmology but are not the same. Pulsating theory suggests that the universe undergoes cycles of expansion and contraction, leading to a series of "big bangs" and "big crunches." In contrast, oscillating theory specifically refers to a model where the universe expands and then collapses repeatedly in a cyclical manner. While both involve cyclical behavior, the terminology and implications can vary based on the context in which they are used.


What are some questions about the Big Bang theory and its implications for the origin of the universe?

Some questions about the Big Bang theory and its implications for the origin of the universe include: What caused the Big Bang? How did the universe evolve after the Big Bang? What evidence supports the Big Bang theory? What are the implications of the Big Bang for our understanding of the universe's beginning and future?


What does the big bang theory have to do with the universes expansion?

It is not so much that the universe is expanding, but rather the rationalization for its expansion that provides evidence to support the Big Bang Theory. The Big Bang supports interpreted observational evidence of the Cosmic Microwave Background Radiation (CMBR) barrier that there is an evolutionary expansion of the universe which promotes a finite age for the universe.


What is one major piece of evidence that supports the validity of the Big Bang theory?

One major piece of evidence supporting the validity of the Big Bang theory is the cosmic microwave background radiation, which is a faint glow of radiation that fills the universe and is considered a remnant of the early stages of the universe's expansion.

What theory does red shift support?

Red shift supports the theory of the expanding universe proposed by Edwin Hubble. The observed red shift in the spectra of distant galaxies indicates that they are moving away from us, providing evidence for the idea that the universe is continuously growing and expanding.


What word supports the theory that the universe is expanding?

Theories explain evidence. There is considerable evidence our universe is expanding. The primary evidence is the red shift of the light from distant galaxies. The further a galaxy is from our local group, the more the light is shifted towards the infrared end of the spectrum. The theory of General Relativity also predicts our universe should be expanding.
