The Origins course tracks the origin of all things – from the Big Bang to the origin of the Solar System and the Earth. The course follows the evolution of life on our planet through deep geological time to present life forms.

What was the early evolution of the “primitive solar nebula” (solar nebula for short)? What is its relation with the circumstellar disks that are ubiquitous around young low-mass stars today? Is it possible to define a “time zero” (t0), the epoch of the formation of the solar system?
Will the universe end? Are there other universes? Possibilities for the Future of the Universe Flat: The expansion of the universe will slow down and stop Closed: The universe will begin to contract Open: The universe will continue to expand forever Possible future depends on dark matter & dar...
Types of planets in the solar system The inner four planets closest to the sun — Mercury, Venus, Earth and Mars — are often called the "terrestrial planets" because their surfaces are rocky. Pluto also has a rocky, albeit frozen, surface but has never been grouped with the four terrestri...

Solar Nebula Based upon Density –Heavier objects are near the center of the solar system –Less dense objects are further away Where are the rock planets located? Gas Planets? Ages of Space Universe 14 Billion years old Solar System 4.6 Billion years old Earth 4.55 Billion years old...
Additionally, all of the heavier elements formed in previous generations of aging and dying stars. What is the age of the solar system relative to the universe? The age of the solar system is estimated to be ~4.6 billion years old. The age of the universe is ~13.8 billion years old. ...
explanation of the origin of the solar system according to which a rotating nebula cooled and contracted, flattening into a disk shape with a central bulge. The matter in the disk condensed into the planets, their moons, asteroids, and comets, while the great mass at the center became the ...
