Abstract:
Entertaining the possibility of time travel will invariably challenge dearly-held concepts in fundamental physics. It becomes relatively easy to construct multiple logical contradictions using differing starting points from various well-established fields of physics. Sometimes, the interpretation is that only a full theory of quantum gravity will be able to settle these logical contradictions. Even then, it remains unclear if the multitude of problems could be overcome. Yet as definitive as this seems to the notion of time travel in physics, such recourse to quantum gravity comes with its own,

Abstract:
This article introduces a groundbreaking approach to interstellar travel by drawing an analogy between a nautical manoeuvre called tacking and a proposed technique for traversing vast interstellar distances, that we termed “time tacking.” In sailing, tacking allows a vessel to move against the wind through a series of zig-zag movements. Similarly, in space travel, a comparable manoeuvre will enable spacecraft to navigate the challenges of relativistic time dilation by entering a “mirror universe” and potentially facilitating transitions into other dimensions. This theoretical framework also pr

Abstract:
This project aims to study general relativity to the extent to understand the occurrence and behaviors of closed timelike curves (CTCs) in several exact solutions of Einstein’s field equations. The rotating black hole solution, the Gödel universe and the cosmic string solutions are studied in detail to show how CTCs arise in these spacetimes. The chronology-violationing paradoxes and other unphysical aspects of CTCs are discussed. The spacetimes where CTCs arise possess properties which are argumented to be unphysical, such as lack of asymptotic flatness and being innite models. With quantum c

More seriously, does this research cast any light on the sorts of problems and puzzles that have featured in the philosophical literature on time travel?

Abstract:
Abstract How do we make a transistor faster? In other words, what can we do to reduce the time it takes to switch it on and then off again? We have already seen that the switching time must be long enough to allow a typical electron to get from one side of the gate region to the other. The simplest way to decrease this time is to reduce the distance that the electron has to travel. This is the route we followed in the previous chapter. An alternative solution is to encourage the electrons to travel faster. This requires a far more subtle approach. To see how we can achieve this we need to have

In 1935, Einstein and Rosen described what is now called the Einstein-Rosen bridge. Wheeler called this a wormhole, which could connect two distant parts of the universe. Thorne and Morris showed the wormhole cannot be traversable unless exotic matter with negative energy props it up. Using the Penrose mechanism of superradiance, one can produce rotational energy from a black hole, which could be used to detect dark matter particles. Higher dimensional objects such as branes in superstring theory have been considered as sources of gravitational waves. Black holes have even been proposed to be

Déjà Vu, the 2006 film starring Denzel Washington directed by Tony Scott, is characterised by a number of glitches, marking aspects of the time-travel media and narrative as well as the condition described in the title. The chapter opens with a consideration of the economic doctrine of perfect communication and argues that no system can be both complete and coherent, so no communication can be both universal and without noise. The glitches are traced especially through a shot-reverse-shot sequence early in the film when the African American protagonist recognises his obligation to a dead Afric

As the electron moves across a boundary, the role of central cell symmetries (i.e., Γ, X, L character) is suppressed; ii) In time dependent quantum description, once again the electron wavepacket is assumed to abruptly see different material properties across a d

Stochastic simulation of a Casimir Oscillator is presented in this paper. This oscillator is composed of a flat boundary of semiconducting oscillator parallel to a fixed plate separated by vacuum. In this system the oscillating surface is attracted to the fixed plate by the Casimir effect, due to quantum fluctuations in the zero point electromagnetic field. Motion of the oscillating boundary is opposed by a spring. The stored potential energy in the spring is converted into kinetic energy when the spring force exceeds the Casimir force, which generates an oscillatory motion of the moving plate

The equation of motion of steepest-entropy-ascent quantum thermodynamics (SEA-QT) was first postulated in the early 1980s with the intent of modeling the non-linear dynamic behavior encountered in nature, which the unitary (linear) dynamics of the Schrödinger-von Neumann equation cannot. The SEA-QT equation is used here to model the decoherence phenomenon between two distinguishable and indivisible elementary constituents of type spin–½ (e.g., quantum bits or qubits). The resulting set of non-linear, first-order differential equations is solved with a fourth-order-Runge-Kutta routine provided
