Macroscopic Traversable Spacewarp (REAL PHYSICS)-Mohammad Mansouryar

This thing is quite technical but a gem for sure. Absolutely no idea where i found this sorry. For that reason I left the original name of the pdf intact in case you wanted to do further research.

Abstract:
A design of a configuration for violation of the averaged null energy condition (ANEC)
and consequently other classic energy conditions (CECs), is presented. The methods of
producing effective exotic matter (EM) for a traversable wormhole (TW) are discussed.
Also, the approaches of less necessity of TWs to EM are considered. The result is, TW and similar structures; i.e., warp drive (WD) and Krasnikov tube are not just
theoretical subjects for teaching general relativity (GR) or objects only an advanced civilization would be able to manufacture anymore, but a quite reachable challenge for current technology. Besides, a new compound metric is introduced as a choice for testing in the lab.

1. Introduction:
It is clear that if a method of faster than light (FTL) travels would be discovered, its most natural consequences, such as contact to probable intelligent entities & colonizing the earth-like planets, could solve many problems of human race [1]. Even if within researching on FTL methods of communication, the related by-products could lead to rapid (not necessarily FTL) ways of transporting humans or things, that situation would be so profitable too [2].
Herein, TWs [3] are considered as the desired spacetime configurations that are able to satisfy the above requests. The main drawback of TWs hinges on their energy implications. In fact, if you want a TW, you need negative energy (NE) – energy less than vacuum energy of Minkowski 4D spacetime – with special conditions.
The stress-energy tensor of a TW metric violates both kinds of CECs [4]; pointwise & averaged. The "pointwise CECs" state, there cannot be local negative energy densities (NEDs) in physical spacetimes, while "averaged CECs" might permit violations of CECs in
some points of spacetime but forbid negative values for energy measurements on the curves related to path of physical objects.
However this is not whole of the story; the re are known violations of CECs, most famous of them – which would be base of present paper – is the experimentally observed Casimir effect (in parallel plate geometry with Dirichlet boundary conditions) [5].
In this paper, I have tried to review the literature , in the spirit of whether the TWs in practice are far reaching or constructible by present knowledge & technology. The
conclusion is they are quite possible to manufacture provided a sufficient determination of investment on improving computation tools & necessary materials.
The basic assumption is a generalization of a research done by Graham & Olum [6]. The calculations supporting my claims are too complicated, so the description will be mostly qualitative, but the principles are standard.
