TITLE
Turing machine engineering and Immortality
AUTHOR
Warren D. Smith
ABSTRACT
We address the either fundamentally important or silly
question of whether the laws of physics permit a Turing machine
(infinite computing device) to exist.
``Can life can exist forever?'' is a similar question.
Although we do not settle the question,
we propose a design which
overcomes obstacles that at first would seem insuperable.
It in fact is a Turing machine (and is an infinitely long-lived
civilization) under certain restrictions.
(Along the way we contribute several new cylindrically symmetric exact
solutions of general relativity.)
KEYWORDS
Philosophy, general relativity, Turing machine,
algorithmicity of physics.
