Models and theories about the universe are always changing because new evidence and observations constantly challenge our understanding of the cosmos. Scientific knowledge is a dynamic process, and as technology and instrumentation improve, our understanding of the universe evolves. Additionally, new discoveries may require revisions or updates to existing models and theories.
The astronomer's understanding of the universe is based on observations, experiments, mathematical models, and theories that have been tested and proven to be consistent with the natural phenomena observed in the universe. By using these methods, the astronomer is able to make predictions and explain the behavior of celestial objects and events.
The Big Bang theory is a scientific explanation for the origins of the universe, proposing that it began as a singularity and has been expanding ever since. Other theories, such as steady-state or oscillating universe models, propose alternative ideas for the origin and evolution of the universe that differ from the Big Bang theory. The key difference lies in how these theories explain the creation and development of the cosmos.
No one really knows what the answer is. there are all sorts of theories - some better than others, but the truth is that we can never say what actually happened. The popular theories keep changing all the time. The more people look into the question, the more unanswered questions they find. Peoplle will say "this happened" and "that happened", but the truth is that they dont know what really happened, so they should say things like "I think this might have happened" instead.

Both Copernicus' and Ptolemy's models aimed to explain the motion of celestial bodies in the sky. However, Copernicus placed the Sun at the center of the universe, while Ptolemy's model had Earth at the center. Both models used the concept of epicycles to explain the retrograde motion of planets.
yes
Yes, the concept of the universe not being locally real is explained in some scientific theories and models, such as quantum mechanics and certain interpretations of quantum physics. These theories suggest that at the quantum level, particles can exist in multiple states simultaneously and their properties are not determined until they are observed. This challenges the idea of a locally real universe where objects have definite properties independent of observation.
Marketing. Methods, Models and Theories
The difference between models and theories is nothing hahahahahaha loser go look in your book
Alexander Friedmann, a Russian mathematician, theorized mathematical models of the universe in 1922, following Einstein's theories. Friedmann's work formed the basis of what we now refer to as the "Big Bang" theory.
A hollow universe would challenge our current understanding of the cosmos by suggesting that there may be empty spaces or voids within the universe. This could impact our theories about the structure and composition of the universe, as well as our understanding of how matter and energy are distributed throughout space. It would require us to reconsider our models of the universe and how it functions.

economic models
they are both speculative
A model is an explanation of why an event occurs, and how data and events are related. So theories and hypothesis are testable statements and broad generalizations to compare data and to collect data.
Scientists estimate that the universe is approximately 13.8 billion years old based on observations of the cosmic microwave background radiation and the expansion rate of the universe. This age is derived from various cosmological models and theories, such as the Big Bang theory.
