Free fall in gravitational theory

Gravitational Waves in the Nonsymmetric Gravitational Theory

We prove that the flux of gravitational radiation from an isolated source in the Nonsymmetric Gravitational Theory is identical to that found in Einstein’s General Theory of Relativity.

Sub-Femto-g Free Fall for Space-Based Gravitational Wave Observatories: LISA Pathfinder Results.

We report the first results of the LISA Pathfinder in-flight experiment. The results demonstrate that two free-falling reference test masses, such as those needed for a space-based gravitational wave observatory like LISA, can be put in free fall with a relative acceleration noise with a square root of the power spectral density of 5.2±0.1  fm s^{-2}/sqrt[Hz], or (0.54±0.01)×10^{-15}  g/sqrt[Hz...

MODEL THEORY Fall 2013

In these notes I will look at that part of ”pre-Morley’s theorem era” model theory that I feel is most relevant for the current trends in model theory. Some of the topics are not chosen because of the theorems but because of the methods behind the proofs. Only the surface of each topic chosen is scratched, for more see [CK] or [Ho]. When we attach some names of persons to theorems, we just indi...

Free fall and cellular automata

Three reasonable hypotheses—homogeneity in time and space, bounded velocity of propagation of information, and bounded density of information—lead to the thesis that physical phenomena can be described and simulated with cellular automata. This implication has in fact been formalized into a theorem both in the classical [6] and the quantum case [1], albeit in flat space. Further evaluating this...
