How to build a time-machine - or more exactly how to contemplate the possibility of its construction.
Even with a limited knowledge of physics this seems as Prof Hawking has said is impossible nevertheless we will try to do the impossible.
Now this may take place by some quirky innovation but it is likely to require a series of interaction of a set of powerful tools.
The first requirement is the have a control system that is capable of organising many layers of self-value an recursion and to hold the information in a real dynamic form - that is the aim of the language Algolx and its development AX1.
The second requirement is to have a mathematics that is able to allow for its development in real energy that is the development to real mathematics -- Mathematica Proxima.
The third requirement is access to the levels of power to generate the forces required - that is being able to work confidently at the particle level.
