What is the current theory about the formation of the solar system?

• The solar system originated from a single massive star that exploded.
• The solar system formed from the collision of multiple planets.
• The solar system was created by a series of cosmic explosions.
• The solar system began as a cloud of dust and gas that condensed, forming a bulging middle and an outer disk. The bulging middle of the cloud became the sun, and the rest of the dust and gas formed the planets.
