Ibelieve that our solar system formed by the same process as star formation. a huge cloud of dust and gas collapsed and condensed. gravity pulled matter into the center core, nuclear fusion began, and our sun was created. remaining matter and gas clumped together to form the planets. i believe in the
big bang theory
condensation theory
nebular theory
oscillating theory

The correct

nebular theory

The explanation:

-The nebular hypothesis is the most widely accepted model in the field of cosmogony to explain the formation and evolution of the Solar System (as well as other planetary systems).

-According to the nebular hypothesis, stars form in massive and dense clouds of molecular hydrogen—giant molecular clouds (GMC). These clouds are gravitationally unstable, and matter coalesces within them to smaller denser clumps, which then rotate, collapse, and form stars. Star formation is a complex process, which always produces a gaseous protoplanetary disk, proplyd, around the young star. This may give birth to planets in certain circumstances, which are not well known.

-the Big bang theory is about the origin of the universe

- and condensation theory relates to the formation of the Moon and the Earth.

not too sure thinking all accelerations are pointed down
