对狭义相对论逻辑体系的思考
狭义相对论 逻辑体系 同时 问题
2015/6/5
1905年伟大的物理学家爱因斯坦创立了狭义相对论，这个理论推动了现代科技的飞跃发展，深刻影响了人类文明。其中狭义相对论有一个重要结论：同时的相对性。本文针对这个结论进行分析，发现狭义相对论的逻辑体系存在问题。
Relativistic analogue of the D'Alembert principle of virtual displacements and the effective actions for the spherically-symmetric charged dust shell in General Relativity
Relativistic analogue D'Alembert principle of virtual displacements effective actions spherically-symmetric charged dust shell General Relativity
2010/12/20
A simple and direct derivation of the variational principle and effective actions for a spherical charged dust shell in general relativity is offered. This principle is based on the relativistic versi...
Fitting galactic rotation curves with conformal gravity and a global quadratic potential

2010/12/21
We apply the conformal gravity theory to a sample of 110 spiral galaxies whose rotation curve
data points extend well beyond the optical disk. With no free parameters other than galactic mass to ligh...
Gravitational Wave Emission from the Single-Degenerate Channel of Type Ia Supernovae
Gravitational Wave Emission Single-Degenerate Channel Type Ia Supernovae
2010/12/21
The thermonuclear explosion of a C/O white dwarf as a Type Ia supernova (SN Ia) generates
a kinetic energy comparable to that released by a massive star during a SN II event. Current
observations an...
The Penrose Inequality and the Fluid/Gravity Correspondence
Penrose Inequality Fluid/Gravity Correspondence
2010/12/21
Motivated by the fluid/gravity correspondence, we consider the Penrose inequality in the frame-
work of fluid dynamics. In general relativity, the Penrose inequality relates the mass and the entropy ...
Reconstructing the massive black hole cosmic history through gravitational waves
massive black hole cosmic history gravitational waves
2010/12/21
The massive black holes we observe in galaxies today are the natural end-product of a complex
evolutionary path, in which black holes seeded in proto-galaxies at high redshift grow through
cosmic hi...
When pressure is not negligible in comparison with energy density, the external gravitational field and the motion of particles in it are modified. For spherically symmetric body two effective mass pa...
Black Hole Entropy, Loop Gravity, and Polymer Physics
Black Hole Entropy Loop Gravity d Polymer Physics
2010/12/20
Loop Gravity provides a microscopic derivation of Black Hole entropy. In this paper, I show
that the microstates counted admit a semiclassical description in terms of shapes of a tessellated horizon....
General formulation of general-relativistic higher-order gauge-invariant perturbation theory
General formulation general-relativistic higher-order gauge-invariant perturbation theory
2010/12/20
Gauge-invariant treatments of general-relativistic higher-order perturbations on generic back-
ground spacetime is proposed. After reviewing the general framework of the second-order gauge-
invarian...
Propagation of the relativistic charged particle in an ultracold atomic gas with Bose-Einstein condensates
Bose-Einstein condensation relativistic charged particles energy losses
2010/11/25
We study theoretically some effects caused by a propagation of the charged particle in a dilute gas of alkali-metal atoms in the state with Bose-Einstein condensates. The energy change of the high-spe...
We study the classical second law of black hole thermodynamics, for Lovelock theories (other than General Relativity), in arbitrary dimensions.Using the standard formula for black hole entropy, we con...
A thermal field theory derivation of the source term induced by a fast parton from the quark energy-momentum tensor
thermal field theory derivation of the source term fast parton quark energy-momentum tensor
2011/1/10
I derive the distribution of energy and momentum transmitted from a fast parton to a medium of
thermalized quarks, or the source term, in perturbative thermal field theory directly from the quark ene...
We consider the motion of tachyons (faster-than-light particles)in the framework of General Relativity. An important feature is the large contribution of low energy tachyons to the energy-momentum ten...
Soft gamma repeaters (SGRs) and anomalous X-ray pulsars (AXPs) are thought to be magnetars:
neutron stars powered by extreme magnetic elds. These rare objects are characterized by repeated and somet...
Energy conditions in modified Gauss-Bonnet gravity
Energy conditions Gauss-Bonnet gravity
2010/12/20
In considering alternative higher-order gravity theories, one is liable to be motivated in pursuing models consistent and inspired by several candidates of a fundamental theory of quantum gravity.
