C1.00001: New Results on Quasar Outflows Joseph Shields A subset of quasars display broad, blueshifted absorption lines in their rest-frame ultraviolet spectra that trace high-velocity outflows that are probably ubiquitous but seen in absorption along only selected lines of sight. These outflows may play a crucial role in removing angular momentum from material that undergoes accretion onto a central black hole, thereby powering these systems. The physical properties of these outflows remain poorly defined. Studies of variability in quasar broad absorption lines provide a promising means of improving physical constraints on these sources. New results on broad absorption line variability will be presented and their implications discussed. [Preview Abstract] |

C1.00002: Gravitational Tests of Relativity Jay D. Tasson, V. Alan Kostelecky Recent studies have revealed new ways to test relativity using gravitational experiments. Results have already been obtained based on lunar laser ranging, torsion pendula, and high- sensitivity gravimetry. Proposals for many more tests exist, some of which could perform the first searches for types of relativity violation that have not yet been sought. In this presentation an outline of the modern theoretical framework for testing relativity, the gravitationally coupled Standard-Model Extension, will be provided along with a summary of recent results and proposals.

C1.00003: Laboratory Test of Newton's Second Law for Small Accelerations Brian Woodahl, Jens Gundlach, Stephan Schlamminger, Chris Spitzer, Ki Choi, Jen Coy, Ephraim Fischbach We have tested the proportionality of force and acceleration in Newton's second law, F=ma, in the limit of small forces and accelerations. Our tests reach well below the acceleration scales relevant to understanding several current astrophysical puzzles such as the flatness of galactic rotation curves, the Pioneer anomaly, and the Hubble acceleration. We find good agreement with Newton's second law at accelerations as small as 5 $\times$ 10$^{-14}$ m/s$^{2}$. [Preview Abstract] |

C1.00004: The Universe according to Schroedinger and Milo Milo Wolff The puzzling electron is due to the belief that it is a discrete particle. Schroedinger, (1937) eliminated discrete particles writing: \textit{What we observe as material bodies and forces are nothing but shapes and variations in the structure of space. Particles are just schaumkommen} (appearances). Thus he rejected wave-particle duality. Schroedinger's concept was developed by Milo Wolff using a Scalar Wave Equation in 3D quantum space to find wave solutions. The resulting Wave Structure of Matter (WSM) contains all the electron's properties including the Schroedinger Equation. Further, Newton's Law F=ma is no longer a puzzle; It originates from Mach's principle of inertia (1883) that depends on the space medium and the WSM. These the origin of all the Natural Laws. Carver Mead (1999) at CalTech used the WSM to design Intel micro-chips and to correct errors of Maxwell's Equations. Applications of the WSM describe matter at molecular dimensions: Industrial alloys, catalysts, biology and medicine, molecular computers and memories. See book ``Schroedinger's Universe'' - at Amazon.com. Pioneers of the WSM are growing rapidly. Some are: SpaceAndMotion.com, QuantumMatter.com, treeincarnation.com/audio/milowolff.htm, daugerresearch.com/orbitals/index.shtml, glafreniere.com/matter.html =A new Universe. [Preview Abstract] |

C1.00005: DM/DE revealed: The physical origin of Lambda-CDM James Beichler In the past few decades two new `crises' affecting fundamental physics have emerged in the observation of phenomena that indicate the existence of Dark Matter and Dark Energy. These are not problems which can be solved by quantum theory or particles, but rather problems that are related to gravity theory as expressed by the general theory of relativity. Numerous ideas and hypotheses have been suggested to explain these new problematic phenomena, but no particular hypothesis or resulting model has proven satisfactory. No model yet proposed seems to be able to explain either DM and DE or both even though theoretical physicists generally agree that the two should have a single common explanation. There is, however, one relatively unknown exception that can explain both DM and DE without any additional hypotheses and this model explains the physical origins of the Lambda-CDM term that others have already proposed adding to general relativity. Yet this new model is not without consequences for the rest of physics and science: Accepting this new model would mean acknowledging the existence of a higher space-like dimension in addition to our normal four-dimensions of space-time.

C1.00006: The Formation of Spaces in the Universe and Its Expansion Yong Wang This article considers multi-layered space. A model for longitudinal space is presented indicating the cause of interaction and relationship among the longitudinal spaces. An interpretation is presented for the real cause of the ``gravitational force'' phenomenon. The universe as stated in physics can be large or small. It is believed that the universe is made up of many multi-layered, independent but interacting spaces and times. Here, we want to emphasize that the interaction we speak of is a one-way interaction from higher spaces to lower spaces. The effect may also be restricted to a limited number of spaces.
