Contextual Outline

The Universe began with a singularity in space-time. After the initial explosion, the Universe started to expand, cool and condense, forming matter. As part of this ongoing process the Sun and the Solar System were formed over 4x109 years ago from a gas cloud which resulted from a supernova explosion. The condensing gas and dust that formed the Sun and the planets contained all its original elements. The planets were formed when matter came together under the influence of gravity.

This module increases students’ understanding of the history of physics, implications of physics for society and the environment and current issues, research and developments in physics.
