physics produced no direct implications for everyday physics.
However, it is expectable that the most fundamental level of
reality, described by the yet to be found theory of quantum gravity,
may have consequences for everyday reality. The latter theory,
which is to unify the quantum theory with the theory of gravity,
may change our notions of space-time dramatically and the demand
that a theory is obtainable as an effective, low-energy description
of quantum gravity may impose substantial limitations on quantities
appearing in that theory. In the talk, I will describe some
implications of a single known law that has origins in the theory
of quantum gravity: the generalised second law of thermodynamics.
The law generalises the usual second law to situations where black
holes are present. The resulting entropy and viscosity bounds will
be considered.
