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.
