A solution to the possible increment in velocity than that of light

Imagine taking grasp the larger distances in the scale of Mega-Parsec or Giga-Parsec and navigating through tunnels of time. The passageways that I would be shortly describing below are not to be misinterpreted as a wormhole although there are few similarities between the two. Theoretical physics often describes things which are beyond the scope of demonstrating experimentally. Argumently, on a theoretical standard our main weapon is to use mathematics to describe the unseenable beauties of nature. This can be easily demonstrated that a spatial cylinder of a non-trivial topology can be made or constructed across the universe passing from one corner of the observable universe to the other corner. The scale of distance if taken into account would be unimaginable and therefore, if any normal, like today’s jet engines or rocket engines are used to circumnavigate through the tunnels then the time scale that’s needed would be at least a billion years or so, million in some cases where the distances are quite small, but although being small, in theoretical cosmology small is accounted for a very arbitrarily large distances by rounding distances thereby giving them a name like ‘light years’, ‘parsecs’, etcetera. The key ingredient or the pickle used to taste up the journey by reducing the distances is by implementation of the warping of space within that tunnel, so that space gets so much twisted inside it, that the present would get unfolded into past and future and also the warping induces such a spatial shortcut, such that CTC’s or closed timelike curves tends to appear in between the cylinder shrinking the limit of ‘mega-parsecs’ to almost nothing at all. Therefore, the play with the distances, we have to manipulate the geometry of space-time, making the notion of time and space smaller and smaller until the point of departing stands a little next to post of arriving. And we have to remember that our weapon for curvature is theoretical physics and abstract mathematics. Gravity is not so important here as because it’s not like a ‘black hole’ without an event horizon or ‘Einstein-Rosen bridges’ but rather this is a simple 3-dimensional topological construction needed to make a ‘mega-parsec’ across cylinder in space and time and alter the geometry of this tunnel in such a way that there exists a ‘warp factor’ and that ‘warp factor’ would tell us precisely how much less time we can take through the tunnel to go from one point of universe to other keeping speed of light in vacuum ‘c’ as the limit paving the way for a real life time machines. Who hasn’t wondered to explore the vast cosmic distances physically rather than visually with the help of space telescopes? But, to do this, we have to construct a warped passageway that is not of higher dimensions but within the limits of our observable dimensions and thereby warping the space inside it in such a clever way so that large distances appears tiny or none at all. The main objective lies in the transformation of a linear velocity to an angular velocity provided that transformation would occur only when the linear velocity crosses the speed of the light thereby the extra or additional velocity that contributes to the existing velocity would no longer contribute in a linear way rather in an angular way creating a cylindrical domain in space-time and the warp factor related in the angular motion of the additional increment in linear velocity warps the space-time inside the cylinder with the aforesaid radius permitting the creation of CTC’s or closed timelike curves which would ultimately help in the shrinking of distances between the place of journey and destination paving the way for faster than time travel without the need for exotic matters or negative energies.

Cosmology analogues in optical systems

We discuss the possibility of exploiting polariton-exciton physics as an analogue experimental tool to study challenging ideas and existing problems arising in the context of gravity theory and theoretical cosmology. We search for cosmology analogues with specific focus on simulating non-equilibrium dynamics across cosmological phase transitions in laboratory as well as employing optical analogue horizons in Bose-Einstein condensates (BECs) and signatures of white hole radiation to study gravitational and cosmological processes. Our analysis aims to uncover conceptual similarities between condensed matter systems and various phenomena in the Early Universe such as the symmetry breaking of the vacuum energy, spontaneous production of particles, false vacuum and cosmic inflation together with a number of unsolved cosmological problems.

Introduction

A brief summary of recent developments in theoretical cosmology is given. The impact of Professor Hawking’s “A Brief History of Time” is put into perspective. Lectures on the subject by Professor Jaki, at a Symposium in Madrid (1990), a Summer Course at El Escorial (1993) and at the UAM, Madrid (2002) are introduced.

The Dark Energy Problem: An Inspiration for New Physics

As much as physics has advanced in the 20th century and the beginning of the current one, reaching astounding accuracy when comparing modern theories of particle physics and general relativity to experimental results, there has been a signi cant progress in observational and theoretical cosmology. Despite these progresses, we have not been able to account for what seems to be nearly 73% of the energy budget of the universe and hence its mystic name 'dark energy'. The dark energy problem provides an inspiration for seeking new laws or symmetries in nature: more precisely, a search for concise and fundamentally simple relationship between the 4D Planck mass and the present size of the universe (or the present value of the Hubble expansion parameter).Keywords: Observational and theoretical cosmology; Dark energy; 4D Planck massThe Himalayan Physics Vol.2, No.2, May, 2011Page: 57-60Uploaded Date: 1 August, 2011

Continual Fascination: The Oscillating Universe in Modern Cosmology

ArgumentUntil the mid-nineteenth century the age-old idea of a cyclic or oscillating universe belonged to philosophical and religious discourse, with little connection to the physical and astronomical sciences. It was only with the emergence of thermodynamics, and even more so with the general theory of relativity, that it became possible to discuss the hypothesis within a scientific context. This paper follows the development of oscillating cosmological models in the twentieth century, when they were often discussed if rarely taken very seriously. How is it that this conception of the universe was seen as both fascinating and controversial? Can the persistence of such models be explained on a scientific basis alone? The idea of an oscillating universe has been in crisis several times, but recently it has experienced a spectacular revival in the form of models inspired by string theory and other theories of quantum gravity. This paper argues that the current revival of interest in cyclic models is not primarily rooted in their “aesthetic” qualities, as used to be the case. With the maturation of cosmology following the discovery of the cosmic microwave background in 1965, the hypothesis has become part of the discourse of modern theoretical cosmology, and as such it is discussed within a normal scientific context. On the other hand, extrascientific considerations continue to play a role, and they probably always will. The heritage from the past is still visible.
