A theory is formed through a systematic process that begins with observations and questions about phenomena. Researchers collect data and conduct experiments to test hypotheses, which are preliminary explanations based on initial observations. As consistent results emerge, these hypotheses are refined, and broader patterns are identified. Ultimately, a theory is established when it successfully explains a wide range of observations and withstands rigorous testing and scrutiny.
The big bang theory
The answer is a theory or a model.
nebular theory
The fission theory, the capture theory, the condensation theory, the colliding planetesimals theory and the ejected ring theory.
This is the theory of abiogenesis - the theory that life can spring fully formed from non-life.
coformation(or sister) theory
The "big" bang theory is the theory that the earth was formed during a collision of space matter. The explosion/collision was so large that the particles in the middle generated life and formed the earth.
No. A theory is formed when lots of data point to a probability. Further data may modify the theory.
The Big Bang Theory
Creationism.
volcano
the collision ring theory is a theory about how the moon formed. It says that a planet sized objoct hit earth while it was still young and exploded on inpact. Then the debris formed the moon as the magma cooled.
