Origin of Earth and Universe

The origin of Earth, and indeed of the universe, is incompletely understood. It is generally accepted that the universe began with a cosmic event called the big bang. The most widely held view is that the big bang took place some 13.7 billion years ago – similar to the age of the oldest known stars.

  • The big bang began in a fraction of a second as an infinitely dense and infinitesimally small bundle of energy containing all of space and time started to expand away in all directions 
  • Origin of Our solar system originated between 4.5 and 5 billion years ago when a nebula – a huge, cold, diffuse cloud of gas and dust – began to contract inward, owing to its own gravitational collapse, forming a hot, dense protostar.
  • This hot center “our Sun” was surrounded by a cold, revolving disk of gas and dust that eventually condensed and coalesced to form the planets.

The origin of the solar system. (1) Diffuse gas cloud, or nebula, begins to contract inward. (2) Cloud flattens into nebular disk as it spins faster around a central axis. (3) Particles in the outer parts of the disk collide with each other to form protoplanets. (4) Protoplanets coalesce into planets and settle into orbits around the hot center. (5) The final product: a central Sun surrounded by eight orbiting planets (solar system not shown in correct scale). The original nebular disk was much larger than our final solar system.
