What are the 4 theories of how the Solar system was made?

1st theory - a cloud of gas and dust was disturbed by a supernova and that explosion made waves in space which squeezed the cloud of gas and dust. Squeezing made the cloud to start to collapse, as gravity pulled the gas and dust together, forming a solar nebula. Just like a dancer that spins faster as she pulls in her arms, the cloud began to spin as it collapsed. Eventually, the cloud grew hotter and denser in the center, with a disk of gas and dust surrounding it that was hot in the center but cool at the edges. As the disk got thinner and thinner, particles began to stick together and form clumps. Some clumps got bigger, as particles and small clumps stuck to them, eventually forming planets or moons.
