Rotating perfect fluid bodies in Einstein's general theory of relativity
The study of rotating astrophysical bodies is of great importance in understanding the structure and development of the Universe. Rotating bodies, are not only of great interest in their own right, for example pulsars, but they have also been targeted as prime possible sources of gravitational …

Length standards and the twin paradox in the special theory of relativity
"In this Thesis I work towards a discussion of several resolutions of the Twin Paradox by exploring the Lorentz transformations. I begin by asking what it means for a moving length to contract1 a question which obviously cannot be divorced from the propagation of length standards from one reference …

The correlation between the special theory of relativity and subsonic compressible fluid mechanics
It is of utmost importance to note that the Sound-Space approach to subsonic compressibility effects is an exact solution to the problem. That is, equation 19.5 is an exact relation between the compressible and incompressible local pressure coefficients. Nowhere in the preceding analysis was it …

Topics in modified gravity
The key element of modern cosmology is the assumption that the General Theory of Relativity (GR) is the correct theory of gravitation. It replaced the Newtonian theory of gravity which was presented in the Principia in 1687. The fundamental idea in GR is that gravity is a manifestation of the …

On aspects of infinite derivatives field theories & infinite derivative gravity
Infinite derivative theory of gravity is a modification to the general theory of relativity. Such modification maintains the massless graviton as the only true physical degree of freedom and avoids ghosts. Moreover, this class of modified gravity can address classical singularities. In this thesis …

An examination of the relation of scientific thought to changing notions of time, space and character in 20th century drama: Chekov, Beckett, Foreman
This study examines and investigates the relation of scientific thought to changing notions of time, space and character in twentieth†century drama. The aim of the study is to illustrate the influence scientific thought had on the zeitgeist of the twentieth†century and how this in turn is …

Testing CPT And Antigravity With Trapped Antihydrogen At ALPHA
… precision antihydrogen experiments allow tests of fundamental theoretical descriptions of nature. These experiments are performed with the ALPHA apparatus, where ultra-low energy antihydrogen is produced and confined in a magnetic trap. Antihydrogen spectroscopy is of primary interest for …

Does the Causal Structure of Space-Time Determine its Geometry
… is it possible to construe the causal structure of space-time as basic and from it to reconstruct the topological and metrical structure of space-time? The problem is first examined within the context of Minkowski space-time (Chapter II) and then generalized to the class of space-time models …

Gauge theories of gravity
A novel alternative to Einstein's general theory of relativity is presented, based on the gauge principle. The gravitational Lagrangian has no Einstein--Hilbert term, but is constructed from quadratic invariants of the Riemann--Cartan curvature and torsion, constituting a geometric gauge theory of …

C. G. Jung and Albert Einstein: From the physical to the psychical relativity of space and time
Despite Carl Gustav Jung’s acknowledgement of Albert Einstein’s influence on his thinking, and despite the significant number of studies into Jung’s interest in physics – and his collaboration with the theoretical physicist Wolfgang Pauli – so far there has been no thorough investigation into the …

"Moving Bodies: James Joyce and the ""New Physics"""
… was an innovator in modern literature, and many of his resources and approaches have been examined thoroughly. Albert Einstein's theory of relativity, however, is an under-explored influence on Joyce's later fiction. As he wrote Ulysses and Finnegans Wake, Joyce culled from the Einsteinian ideas …

Gravitational microlensing and the search for extrasolar planets
… microlensing events. Since the early conception of gravitational lensing before Einstein’s General Theory of Relativity, physicists and astronomers of the early 18th century speculated that light, if treated as particle, can be affected by gravitational field. Gravitational Microlensing is …

The search for gravitational wave bursts in data from the second LIGO science run
The network of detectors comprising the Laser Interferometer Gravitational-wave Observatory (LIGO) are among a new generation of detectors that seek to make the first direct observation of gravitational waves. While providing strong support for the General Theory of Relativity, such observations …

Techniques for improving the readout sensitivity of gravitational wave antennae
The detection of gravitational waves (GWs) from astrophysical sources shows promise as a new method to probe extremely energetic phenomena and test the strong field limit of the general theory of relativity. The era of the first generation of broadband interferometric GW antennae is now drawing to …

Quantifying the impact of data quality on searches for gravitational waves from binary coalescing systems with LIGO

Measurement of the mechanical loss of test mass materials for advanced gravitational wave detectors
Einstein's General Theory of Relativity (1916) predicted the existence of gravitational waves. These waves can be considered as fluctuations, or ripples, in the curvature of space-time. Until now there has been only indirect evidence, produced by Hulse and Taylor, of their existence. However, for …

Epistemic Rationality and Justification
The main thesis of this dissertation is that epistemic rationality is different from justification. While justified beliefs must be likely to be true, a belief with low probability can nevertheless be epistemically rational because informativeness is an important factor to consider in assessing the …

Modal control with state estimation for advanced LIGO quadruple suspensions
