Big History Project: Our Solar System & Earth

The formation and evolution of the Solar System began 4. This model, known as the nebular hypothesis was first developed in the 18th century by Emanuel Swedenborg , Immanuel Kant , and Pierre-Simon Laplace. Its subsequent development has interwoven a variety of scientific disciplines including astronomy , physics , geology , and planetary science. Since the dawn of the space age in the s and the discovery of extrasolar planets in the s, the model has been both challenged and refined to account for new observations. The Solar System has evolved considerably since its initial formation. Many moons have formed from circling discs of gas and dust around their parent planets, while other moons are thought to have formed independently and later been captured by their planets. Still others, such as Earth's Moon , may be the result of giant collisions.

The belief that Earth's sediments, were deposited in an orderly sequence in a year's time defies all geological observations and physical principles concerning sedimentation rates and possible quantities of suspended solid matter, and that extinctions instead occur when the Sun passes through the galaxy's spiral arms.

These individuals often believe that the present physical form of Earth can be explained by "catastrophism," including a worldwide flood, and that all living things including humans were created miraculously. These arms are contained in what is called the disk of the galaxy.
