Explaining Holographic Dark Energy
dark energy holographic principle holographic dark energy UV/IR connection bulk holography spacetime foam quantum fluctuations of spacetime
2016/6/13
The possible holographic origin of dark energy is investigated. The main existing explanations, namely the UV/IR connection argument of Cohen et al, Thomas' bulk holography argument, and Ng's spacetim...
A discrete model of energy-conserved wavefunction collapse
wavefunction collapse conservation of energy discrete time
2016/6/13
Energy nonconservation is a serious problem of dynamical collapse theories. In this paper, we propose a discrete model of energy-conserved wavefunction collapse. It is shown that the model is consiste...
The Strong and Weak Senses of Theory-Ladenness of Experimentation:Theory-Driven versus Exploratory Experiments in the History of High-Energy Particle Physics

2016/5/30
In the theory-dominated view of scientific experimentation, all relations of theory and experiment are taken on a par; namely, that experiments are performed solely to ascertain the conclusions of sci...

The physical origin of holographic dark energy (HDE) is investigated. The main existing explanations, namely the UV/IR connection argument of Cohen et al, Thomas' bulk holography argument, and Ng's sp...
On Tensorial Concomitants and the Non-Existence of a Gravitational Stress-Energy Tensor
general relativity gravitational energy tensor concomitants
2009/9/11
Based on an analysis of what it may mean for one tensor to depend in
the proper way on another, I prove that, under certain natural
conditions, there can be no tensor whose interpretation could be

Theory Construction and Experimentation in High Energy Particle Physics, Circa 1960-1970.
scientific experimentation theory-ladenness of experimentation
2008/4/21
In this paper, I address the issue of to what extent the theory-dominated view of scientific experimentation describes scientific practice. I rely on a time period from the history of High Energy Phys...
Losing energy in classical, relativistic and quantum mechanics.
Zeno supertask conservation laws
2008/4/15
A Zenonian supertask involving an infinite number of colliding balls is considered, under the restriction that the total mass of all the balls is finite. Classical mechanics leads to the conclusion th...
I consider the arguments to show that the vacuum energy density should receive a large contribution from the zero-point energy. This is the cosmological constant problem, as it was originally framed. ...
High Energy Physics and Constructive Empiricism
elementary particle physics constructive empiricism
2008/4/14
Progress in elementary particle physics in recent decades has changed the status of the visible phenomena in the context of scientific research. Empiricist positions in philosophy of science, which pu...
Dark Energy And Life's Ultimate Future
Cosmology Universe Dark Energy Cosmological Constant
2008/4/11
The discovery of the present accelerated expansion of space changed everything regarding cosmology and life's ultimate prospects. Both the optimistic scenarios of an ever (but decelerated) expanding u...
