The Beginning of the Universe
• The universe was created 12-14 billion years ago in an event known as the big bang
• The universe started at an incredibly small volume
• It rapidly expanded and cooled• four fundamental forces (gravity,
electromagnetism, and the strong and weak nuclear forces) were created
The beginning of The galaxy
• The young universe did not have a perfectly even distribution of energy and particles.
• Concentrations of matter formed into clouds, then condensed into stars and the collections of stars we call galaxies.
• We live in a Galaxy known as the Milky Way
The Birth of the Solar System
• The most prevalent theory is the Nebula theory.
• Nebula: an interstellar cloud of dust, hydrogen gas and plasma
• It is called the red planet because it is covered in rusted Iron• Contains the solar system’s
biggest volcano (known as Olympus Mons)
• Atmosphere consisting of CO2• It is believed that it may have had life earlier on.• There are signs that there once was liquid water.• Is the most similar planet to Earth.
Exploring Mars
• Mars has been extensively studied
• Currently NASA would like to see if there is liquid water at the polar ice caps
