If one looks at the biggest structures in the universe, one             discovers that our "neighborhood", the region of space near our                 galaxy, is remarkably similar to other regions of similar size,                 located elsewhere in the universe.  In fact our universe appears                to be very much the same in all directions.  This property is                   shared by the very cold radiation, discovered in 1965, which was                left behind by the big-bang.                                                            To explain this fact in a way that is consistent with                   Einstein's theory of relativity is very difficult, and has forced               cosmologists to consider a new theory of how the universe began.                In this theory the universe "inflates" and grows very rapidly in                size during a very short period of time.  This project shall                    investigate under what conditions such a stage is consistent with               the laws of quantum mechanics, which are the laws that govern                   matter at very tiny length scales.  It shall also seek to                       understand better how gravitons, the light-like particles that                  transmit gravitational forces, are produced during such an                      inflationary stage, and how they could affect the appearance of                 the cold radiation left over from the big-bang.
