Dark Origins: Departure from an Ex-Nihilo Big Bang

With the growing body of research on Black Holes, it is becoming increasingly apparent that these celestial objects may have a stronger part to play in the universe than previously thought, shaping galaxies and influencing star formation. In this manuscript, I take these findings a step further, proposing a new set of boundary conditions to both the early and late Universe, extrapolating from thermodynamics. I propose that the Universe will collapse into a massive black hole and that the Big Bang is a result of a collision or interaction between Supra Massive Black Bodies (SMBBs, black holes at the mass scale of our ‘Universe’) of opposite matter type (baryonic and anti-baryonic) and disproportionate masses, a stark departure from the classical Ex-Nihilo creation (from nothing) approach. Such a collision, between a matter and anti-matter SMBB, with disproportionate masses could account for both the explosion referenced as the big bang, as well as the drastic baryonic asymmetry that we observe. Expulsion of black body material from the interaction could also account for Primordial Seed Black holes

Stability of Surface-Immobilized Lubricant Interfaces under Flow

The stability and longevity of surface-stabilized lubricant layers is a critical question in their application as low- and nonfouling slippery surface treatments in both industry and medicine. Here, we investigate lubricant loss from surfaces under flow in water using both quantitative analysis and visualization, testing the effects of underlying surface type (nanostructured versus flat), as well as flow rate in the physiologically relevant range, lubricant type, and time. We find lubricant losses on the order of only ng/cm2 in a closed system, indicating that these interfaces are relatively stable under the flow conditions tested. No notable differences emerged between surface type, flow rate, lubricant type, or time. However, exposure of the lubricant layers to an air/water interface did significantly increase the amount of lubricant removed from the surface, leading to disruption of the layer. These results may help in the development and design of materials using surface-immobilized lubricant interfaces for repellency under flow conditions.Chemistry and Chemical BiologyEngineering and Applied Science
