                        Reverse Engineering the Universe

Kivonatos ismertetés:
Careful observations over the past sixty years guided by basic principles of 
physics including, especially, Albert Einstein’s General Relativity, have 
allowed cosmologists to reconstruct the history of the universe and to describe
it using a remarkably simple standard model. This narrative begins with an 
epoch of rapid acceleration, called inflation when the seeds of contemporary 
structure were sown. This was followed by a period decelerating expansion while
the universe, cooled off. In recent times it has started to accelerate again 
due to the dominance of a cosmological constant.  This standard model has 
proven to be quite resilient to observational challenge and more tests are on 
the way. However, many questions remain unanswered. One of these is how much 
can be learned about the largest scale structure of the actual universe we 
inhabit.
