According to general relativity every bit of the collapsed star and every particle that falls afterwards into the black hole will end up at a last moment of time, at which the density of matter and strength of the gravitational field become infinite.

Lee Smolin (1997)



One can … always ask, why is the universe where it is, rather than ten feet to the left, or rotated 30 degrees? Or, why did the universe not start five minutes later? This is sometimes called the problem of under-determination: nothing in the laws of physics answers the question of why the universe is where it is, rather than translated or rotated.

Lee Smolin (2008)



It should also be said that for physicists relationalism is a strategy. As we shall see, theories may be partly relational, i.e., they can have varying amounts of background structure.

Lee Smolin (2008)



It is becoming clearer and clearer that the hardest problem faced by theoretical physics is the problem of accounting for the small value of the cosmological constant.

Lee Smolin (2005)



What is the universe? Is it infinite, or finite?

Lee Smolin (1997)



The problem of how to make a theory of a whole universe is thus the problem of how to construct a theory without making any reference to anything that exists … outside of the system we are describing.

Lee Smolin (1997)



No matter how smart she is, no matter how modern her methods and how tricky her reasoning, a detective cannot be a good detective unless in the end the bad guys are found out. It is the same with science.

Lee Smolin (1997)



At present … the question of what happens inside of a black hole when quantum effects are taken into account remains unresolved.

Lee Smolin (1997)



It is mathematics, more than anything else, that is responsible for the obscurity that surrounds the creative processes of theoretical physics.
