The Universe in a Nutshell by Stephen Hawking Apparently a large number of the many millions who bought A Brief History of Time got stuck on page one Oh dear I expected more of my readers With this in mind I have now simplified some of the ideas in the hope you will make it to page two But since you had no idea of what I was talking about first time round this is almost certainly a total waste of time Still as Einstein pointed out there is no universal quantity called time Instead everyone has his or her own personal time and mine dare I say it is more valuable than yours This is one of the postulates of the theory of relativity - so called because it implied that only relative motion was important Relativity was not compatible with Newtons law of gravity and from this Einstein inferred that it is not space that is curved but spacetime itself This led us to understand that the universe is expanding Sadly relativity breaks down at Big Bang because it is not compatible with quantum theory Alas despite having worked on this problem myself we still dont have a grand unified theory of the origin of the universe But back to time Although I have my own personal time I cannot actually say what it is I can only describe the mathematical model for it The singularity theorems of Roger Penrose and myself established that spacetime is bounded to the past by regions in which quantum gravity is important So to understand the universe we need a quantum theory of gravity Supersymmetries provided a natural physical mechanism to cancel the infinities arising from ground state fluctuations This led to the discovery of supergravities and superpartners However in 1985 people realised there was no reason not to expect infinities and this led to one dimensional extended object superstring theories But that wasnt it
