Why Did The Collapse Of Our Solar System

Most scientists think that our solar system was made from a nearby star, called the supernova. These scientists believe that the explosion of the supernova squeezed a nearby cloud of dust, causing it to collapse. When the gravity gathered the dust together, it formed something called a solar nebula. Soon, the cloud became hotter, a disk of gas surrounding it. Molecules gathered in a clump as the disk got smaller.
Scientists believe in this theory using technology. They used this technology to observe and watch the birth of other stars much like the sun. They saw that these stars were created by a cloud of dust. Using this information, scientists made their hypothesis. This is how the theory came along.
It is believed that most of this cloud
