Why not steady and Quasi staedy state?

In summary, the Big Bang theory is widely accepted because it is consistent with a large amount of experimental and observational evidence. On the other hand, the steady state and quasi steady state theories are not accepted because they are inconsistent with many of these results, particularly those related to the cosmic microwave background.

Because:

a) the former ("the Big Bang theory") is consistent with a huge number of experimental and observational results, within its stated domain of applicability; and

b) the latter ("the steady state and quasi steady state") are inconsistent with a great many such results.

A widely cited paper outlining a) is http://arxiv.org/abs/astro-ph/0603449" [Broken], by Spergel et al. (the link takes you to the arXiv preprint).

At an extreme level of summary, it is the quantitative details of the CMB (cosmic microwave background) observations which b) are most strongly inconsistent with.

1. Why is steady state important in scientific research?

Steady state is important because it allows for the accurate measurement and observation of a system's behavior over time. This helps scientists to better understand how a system functions and how it may respond to changes.

2. What is the difference between steady state and quasi-steady state?

Steady state refers to a system that has reached a stable equilibrium, where the inputs and outputs are balanced. Quasi-steady state, on the other hand, refers to a system that is close to reaching steady state but is still experiencing small changes. In this state, the system is almost stable but not quite.

3. When is it appropriate to use quasi-steady state analysis?

Quasi-steady state analysis is commonly used in systems that are constantly changing or where the steady state cannot be easily achieved. It can also be used when studying the initial stages of a system's behavior before it reaches steady state.

4. What are the limitations of steady state and quasi-steady state analysis?

While steady state and quasi-steady state analysis can be useful in understanding a system's behavior, they are not always accurate representations of real-world systems. They assume that a system is linear and does not take into account external factors that may affect the system's behavior.

5. Are steady state and quasi-steady state concepts used in all scientific fields?

Steady state and quasi-steady state concepts are commonly used in fields such as physics, chemistry, and engineering where the behavior of systems can be modeled and observed. However, they may not be applicable in fields such as biology or economics where systems are more complex and difficult to predict.
