Hydrodynamics of structure formation

In summary, the authors of arXiv:0809.2330 argue that the standard LambdaCDM model has flaws due to its assumption of linear, collisionless, and ideal flows. Instead, they propose a turbulent big bang and top-down viscous-gravitational fragmentation from supercluster to galaxy scales, supported by observations of turbulence and linear morphology in the early universe. They also suggest that gas-protogalaxies fragment into primordial-density clumps, which could explain observations such as dimmed SNe Ia events and false gamma-ray-burst luminosity distances.

Theory and observations reveal fatal flaws in the standard LambdaCDM model. The cold dark matter hierarchical clustering paradigm predicts a gradual bottom-up growth of gravitational structures assuming linear, collisionless, ideal flows and unrealistic CDM condensations and mergers. Collisional fluid mechanics with viscosity, turbulence, and diffusion predicts a turbulent big bang and top-down viscous-gravitational fragmentation from supercluster to galaxy scales in the plasma epoch, as observed from 0.3 Gpc void sizes, 1.5 Gpc spins and Kolmogorov-fingerprint-turbulence-signatures in the CMB. Turbulence produced at expanding gravitational void boundaries causes a linear morphology of 3 Kpc fragmenting plasma-protogalaxies along vortex lines, as observed in deep HST images. After decoupling, gas-protogalaxies fragment into primordial-density, million-solar-mass clumps of earth-mass planets forming 0.3 Mpc galactic-dark-matter. White-dwarf-heated planet-atmospheres give dimmed SNe Ia events and false gamma-ray-burst luminosity distances, not dark-energy-Lambda. Quasar microlensing observations rule out no-hair black hole models and require galaxy-dark-matter to be planets-in-clumps.

So the authors believe that the universe should behave like a liquid?

sysreset, if you read down to conclusion it is explained.
 

Related to Hydrodynamics of structure formation

1. What is the definition of hydrodynamics of structure formation?

Hydrodynamics of structure formation refers to the study of the dynamics and evolution of large-scale structures in the universe, such as galaxies and galaxy clusters, driven by the interactions between gas and gravity.

2. How does the hydrodynamics of structure formation contribute to our understanding of the universe?

The study of hydrodynamics of structure formation helps us understand the processes that shape the large-scale structure of the universe, such as the formation of galaxies and the distribution of dark matter. It also provides insights into the evolution of the universe and the physical laws that govern it.

3. What are the main factors that influence the hydrodynamics of structure formation?

The main factors that influence the hydrodynamics of structure formation are gravity, gas dynamics, and the properties of the dark matter that makes up the majority of the matter in the universe. Other factors such as radiation and magnetic fields can also play a role.

4. How do scientists study the hydrodynamics of structure formation?

Scientists use a combination of theoretical modeling and observations to study the hydrodynamics of structure formation. This involves simulating the evolution of the universe using computer simulations and comparing the results to observations from telescopes and other instruments.

5. What are some current research topics in the field of hydrodynamics of structure formation?

Some current research topics in the field of hydrodynamics of structure formation include the effects of baryonic physics (such as gas cooling and star formation) on the evolution of structures, the role of feedback processes (such as supernovae and black hole activity) in shaping the structure of galaxies, and the use of large-scale surveys to map the distribution of matter in the universe.
