Hydro-Gravitational Dynamics of Planets and Dark Energy
Self gravitational fluid mechanical methods termed hydro-gravitational-dynamics (HGD) predict plasma fragmentation
0.03 Myr after the turbulent big bang to form protosuperclustervoids, turbulent protosuperclusters, and protogalaxies at
the 0.3 Myr transition from plasma to gas. Linear protogalaxyclusters fragment at 0.003 Mpc viscous-inertial scales
along turbulent vortex lines or in spirals, as observed. The plasma protogalaxies fragment on transition into white-hot
planet-mass gas clouds (PFPs) in million-solar-mass clumps (PGCs) that become globular-star-clusters (GCs) from tidal
forces or dark matter (PGCs) by freezing and diffusion into 0.3 Mpc halos with 97% of the galaxy mass. The weakly
collisional non-baryonic dark matter diffuses to > Mpc scales and fragments to form galaxy cluster halos. Stars and
larger planets form by binary mergers of the trillion PFPs per PGC, mostly on 0.03 Mpc galaxy accretion disks. Stars
deaths depend on rates of planet accretion and internal star mixing. Moderate accretion rates pro-duce white dwarfs
that evaporate surrounding gas planets by spin-radiation to form planetary nebulae before Supernova Ia events,
dimming some events to give systematic distance errors, the dark energy hypothesis, and overestimates of the universe

'Tilting' the Universe with the Landscape Multiverse: The 'Dark' Flow
The theory for the selection of the initial state of the universe from the
landscape multiverse predicts superhorizon inhomogeneities induced by nonlocal
entanglement of our Hubble volume with modes and domains beyond the horizon.
Here we show these naturally give rise to a bulk flow with correlation length
of order horizon size. The modification to the gravitational potential has a
characteristic scale , and it originates from the
preinflationary remnants of the landscape. The 'tilt' in the potential induces
power to the lowest CMB multipoles, with the dominant contribution being the
dipole and next, the quadrupole. The induced multipoles are aligned
with an axis normal to their alignment plane being oriented along the preferred
frame determined by the dipole. The preferred direction is displayed by the
velocity field of the bulk flow relative to the expansion frame of the
universe. The parameters are tightly constrained thus the derived modifications
lead to robust predictions for testing our theory. The 'dark' flow was recently
discovered by Kashlinsky et al. to be about which seems in good
agreement with our predictions for the induced dipole of order .
Placed in this context, the discovery of the bulk flow by Kashlinsky et al.
becomes even more interesting as it may provide a probe of the preinflationary
physics and a window onto the landscape multiverse.Comment: 7 pgs, 2 fig
UBVRI Light curves of 44 Type Ia supernovae
We present UBVRI photometry of 44 Type la supernovae (SNe la) observed from 1997 to 2001 as part of a continuing monitoring campaign at the Fred Lawrence Whipple Observatory of the Harvard-Smithsonian Center for Astrophysics. The data set comprises 2190 observations and is the largest homogeneously observed and reduced sample of SNe la to date, nearly doubling the number of well-observed, nearby SNe la with published multicolor CCD light curves. The large sample of [U-band photometry is a unique addition, with important connections to SNe la observed at high redshift. The decline rate of SN la U-band light curves correlates well with the decline rate in other bands, as does the U - B color at maximum light. However, the U-band peak magnitudes show an increased dispersion relative to other bands even after accounting for extinction and decline rate, amounting to an additional ∼40% intrinsic scatter compared to the B band
Do micro brown dwarf detections explain the galactic dark matter?
The baryonic dark matter dominating the structures of galaxies is widely considered as mysterious, but hints for it have been in fact detected in several astronomical observations at optical, infrared, and radio wavelengths. We call attention to the pattern of star formation in a galaxy merger, the observed rapid microlensing of a quasar by a galaxy, the detection of "cometary knots" in planetary nebulae, and the Lyman-alpha clouds as optical phenomena revealing the compact objects to be primordial gas planets in dense clumps that merge to form stars and globular star clusters. Radio observations of "extreme scattering events" and "parabolic arcs" are found to imply the same population of compact planet mass objects in interstellar space, and measurement of the cometary knots yield mass estimates of approximately earth mass as predicted. Estimates of their total number show that they comprise enough mass to constitute the missing baryonic matter. Mysterious radio events are explained by their pair merging in the Galaxy. Latent heat of evaporated hydrogen slowly released at the 14 K freezing transition at their surface explains the thermostat setting of the "dust" temperature of cold galaxy halos. The proportionality of the central black hole mass of a galaxy and its number of globular clusters is explained
