Atomic structure Quote by Lee Smolin
““Both loop quantum gravity and string theory assert that there is an atomic structure to space. In the next two chapters we shall see that loop quantum gravity in fact gives a rather detailed picture of that atomic structure. The picture of the atomic structure one gets from string theory is presently incomplete but, as we shall see in Chapter 11, it is still impossible in string theory to avoid the conclusion that there must be an atomic structure to space and time. In Chapter 13 we shall discover that both pictures of the atomic structure of space can be used to explain the entropy and temperature of black holes.””
About This Quote
Source Book: The Trouble with Physics, Lee Smolin, 2006
The quote explains that both loop quantum gravity and string theory propose space is made of discrete units, and that these ideas help describe black hole thermodynamics.
In simple terms: Space is made of tiny building blocks; this helps explain black holes.
