Unit 1 Origin of matter and Energy: FAQ


Waves from the EM spectrum are collected by telescopes that help reveal the origins of the universe. Analysis of the EM spectrum from stars provides evidence for the Big Bang Theory.  After the Big Bang elements were made by nuclear fusion reactions in stars and supernova explosions.  These elements formed the material for the nebular cloud that formed the solar system and Earth.  The nuclear fusion reaction inside our own star, the Sun, provides energy for the Earth.


All stars and most of the universe is made of Hydrogen and Helium, why is this?
