Trillion Theory (TT), a new theory, estimates the cosmic origin at one trillion years. This calculation of thousands of eons is based upon a growth factor where solar systems age-out at a max of 15 billion years, only to recycle into even larger solar systems, inside of ancient galaxies that are as old as 200 billion to 900 billion years. TT is a new brash cosmology theory proposing many new radical ideas. These proposed ideas should be given credence, as such small changes can give rise to large consequences in speeding the present cosmic revolution. All astronomers must undertake greater introspection by performing forensics on black holes throughout cosmos. This article discusses the following topic areas: TT's background, big questions TT answers, the basics of TT, how Earth formed into a sphere, how the sun formed, law of all spheres by T Theory, how the solar system formed, how galaxies became cosmic hotels, materials used to build cosmos, how cosmos grew ever-larger, cosmic design in Trillion Theory, the goals of TT, and proofs of TT.
