The use of "handy singularities" (i.e. singularities similar to those arising in the Deutch-Politzer space) enables one to avoid (almost) all known difficulties inherent usually to creation of time machines. A simple method is discussed for constructing a variety of such singularities. A few 3-dimensional examples are cited. 
Traversable acausal retrograde domains in spacetime
In this paper we present geometry which has been designed to fit a layperson's description of a 'time machine'. It is a box which allows those within it to travel backwards and forwards through time
Global Spacetime Structure
Here, we outline the basic structure of relativistic spacetime and record a number of facts. We then consider a distinction between local and global spacetime properties and provide important
How to build a space machine
It is widely believed that causality forbids anything to move faster than light. However, recently it has been shown that this fact by itself does not preclude (almost) instantaneous communication
Turing Machines
In 1 900 David Hilbert, the preeminent mathematician of his time, chal­ lenged the world of mathematics with a list of unsolved problems, pre­ sented in Paris before the International Congress of M
