Astronomical Unit is usually used to measure the distance within the solar system Parsec: The parsec is the unit of length used to measure the large distances to astronomical objects which are outside of the solar system.  1 Parsec = 31 trillion kilometre                         1 Parsec = 210,000 astronomical units AU 1 Parsec

COSMIC EXPANSION Inflation theory was first proposed by Alan Guth in 1979 at Cornell University US. In Physics "universe expansion" is the exponential growth of the space in the universe. The inflationary epoch lasted from about 10^-36 seconds from the big bang event to sometimes between 10^-33 to 10^-32 seconds after the big bang singularity. Cosmic Inflation explains various critical conepts   Why universe is Homegeneous ? Why universe is flat ? Why Cosmic Mirowave Background Radiations (CMBR) disturbed ? Eternal Inflation: Eternal inflation is a hypotheical inflationary universe model, which is itself an outgrowth or extension of the big bang theory. According to the eternal inflation. The inflation phase of the universe lasts forever throughout the universe. Three Puzzles: Cosmic inflation give answer to the following puzzles or mysteries of the universe. The universe is so uniform on large scale. Normally different objects are same because they have been in contact some
