At present, physicists … search only for continuous pictures of fundamental physics. Maybe, one day, they will be motivated to look at possible structures of a fundamentally discrete world.

John Barrow (2007)



[T]he entropy level at the beginning of the expansion of the Universe must have been staggeringly small, which implies that the initial conditions were very special indeed.

John Barrow (2007)



Whereas most physicists regard the second law of thermodynamics as a reflection of the improbability of certain types of initial conditions, there are others who regard it as a far more fundamental idea that is prior to the laws of nature themselves.

John Barrow (2007)



There is one qualitative aspect of reality that sticks out from all others in both profundity and mystery. It is the consistent success of mathematics as a description of the workings of reality and the ability of the human mind to discover and invent mathematical truths.

John Barrow (2007)



The traditional view that initial conditions are for the theologians and evolution equations for the physicists seems to have been overthrown―at least temporarily.

John Barrow (2007)



The study of the Wave Function of the Universe is in its infancy. It will undoubtedly change in many ways before it is done.

John Barrow (2007)



What we really want is some principle that tells us why the organization of the Universe changes in the way that it does: why it now expands so uniformly and isotropically.

John Barrow (2007)



The question of why the Universe is as it is, is inextricably linked to that of why fundamental physics is the way that it is.

John Barrow (2007)



The message seems to be this: reality is non-local, so get used to it.

Jim Baggott (2004)
