What are the theories behind the revolution of the universe?

The two main theories behind the revolution of the universe are the Big Bang theory and the steady state theory. The Big Bang theory proposes that the universe began from a very hot, dense state and has been expanding ever since. The steady state theory suggests that the universe has always existed in a constant state, with new matter continuously being created to maintain a constant density as the universe expands.


What is a sientific theory?

Scientific theory involves a collection of concepts of observable phenomena expressed as quantifiable properties with rules (laws) that express relationships between the observations of such concepts. A theory is a good theory if it satisfies two requirements: It must accurately describe a large class of observations on the basis of a model that contains only a few arbitrary elements, and it must make definite predictions about the results of future observations.


What two things do astrominists do?

Astronomers study celestial objects and phenomena, such as stars, planets, and galaxies, to understand the universe's structure and evolution. They often use telescopes and other instruments to collect data, analyze it, and develop theories about cosmic processes. Additionally, astronomers may engage in public outreach and education to share their findings with the broader community.


How could you combine the following two questions into one question Ex- Who KnowsDoes the universe have nine planets Is it - Who Knows if the universe has nine planets or?

Those are both poorly worded versions of the same question. The question should read:"Does the universe have nine planets?"And the answer is:"No. The Universe has trillions and trillions of planets, but our solar system has eight planets."

Is it possible to change a stated theory in the scientific world?

I think Scientific Theories can be changeable. If we find new theories that prove others wrong, that scientific theory can be proved wrong. Galileo used shapes of different masses at the Leaning Tower of Pisa. He had refuted the theory about free falling objects, championed by Aristole. So there you have it! He changed a scientific theory! Actually, two! He proved that the earth was NOT in the center of the universe, which had been accepted since ancient time. People can scientific theories CAN be changeable. Not unchangeable.
