Description

Cosmic limit to information storage

Jacob Bekenstein to give public lecture on the limits of information and
black holes

Jacob
BekensteinIn a society increasingly concerned with information
storage and management, it is intriguing to learn that even the universe has its
own limits.

Jacob Bekenstein, the Polak Professor of Theoretical Physics
at the Hebrew University in Jerusalem, will give a public lecture at the
University of Calgary on Wed., June 2, about the absolute limit to information
storage in any region of space and time by thinking of our world as a boundary
for a larger-dimensional universe.

Bekenstein is renowned for his theory
of black hole thermodynamics, which resulted in the famous Bekenstein-Hawking
theory of black-hole radiation.

His presentation will show how the laws
of heat, disorder and gravitational collapse reveal the ultimate limits to
information storage and behaviour of complex systems.

This revelation
arises as a holographic correspondence between the laws of our universe with the
laws for the boundary of a higher-dimensional universe.

The holographic
principle is a property of quantum gravity and string theories.

The
description of a volume of space can be thought of as encoded on a boundary to
the region. The theory of holographic correspondence suggests that the entire
universe can be seen as a four-dimensional information structure 'painted' on
the cosmological horizon.
