引力流体动力学与空洞、金斯星系团和MACHO暗物质的观测
Gravitational hydrodynamics vs observations of voids, Jeans clusters and MACHO dark matter
摘要:
引力流体力学承认流体力学本质上是非线性和粘性的。在等离子体中,在$z=5100$,粘性长度进入视界并导致分裂成被空隙包围的等离子体团块。后者现在已经扩大到38 Mpc,解释了宇宙空洞尺度$30/h=42$ Mpc。在退耦之后,金斯机制将所有物质分裂成约40,000太阳质量的团块。由于地球重量的毫褐矮星的粘性,它们中的每一个都碎裂,因此每个金斯星系团都包含数十亿个这样的星系团。Jeans团簇在等温模型中充当理想气体粒子,解释了旋转曲线的平坦化。老球状星团中的第一批恒星是由毫棕矮星聚集而成的,没有暗周期。当吉恩星系团彼此靠近并加热冷却的毫褐矮星时,恒星也会形成,然后膨胀并合并形成新的恒星。这解释了Tully-Fischer和Jackson-Faber关系,以及星系合并中年轻球状星团的形成。在类星体微透镜中观测到了数千颗毫褐矮星,在赫胥黎行星状星云中观测到了大约40,000颗。而毫棕矮星,即,暗重子,构成银河系的暗物质,团簇暗物质可能由1.5 eV的中微子组成,在退耦处自由流动。这两种类型的暗物质解释了大量的观测结果。
英文摘要:
Gravitational hydrodynamics acknowledges that hydrodynamics is essentially nonlinear and viscous. In the plasma, at $z=5100$, the viscous length enters the horizon and causes fragmentation into plasma clumps surrounded by voids. The latter have expanded to 38 Mpc now, explaining the cosmic void scale $30/h=42$ Mpc. After the decoupling the Jeans mechanism fragments all matter in clumps of ca 40,000 solar masses. Each of them fragments due to viscosity in millibrown dwarfs of earth weight, so each Jeans cluster contains billions of them. The Jeans clusters act as ideal gas particles in the isothermal model, explaining the flattening of rotation curves. The first stars in old globular clusters are formed by aggregation of milli brown dwarfs, without dark period. Star formation also happens when Jean clusters come close to each other and agitate and heat up the cooled milli brown dwarfs, which then expand and coalesce to form new stars. This explains the Tully-Fischer and Jackson-Faber relations, and the formation of young globular clusters in galaxy mergers. Thousand of milli brown dwarfs have been observed in quasar microlensing and some 40,000 in the Helix planetary nebula. While the milli brown dwarfs, i.e., dark baryons, constitute the galactic dark matter, cluster dark matter consists probably of 1.5 eV neutrinos, free streaming at the decoupling. These two types of dark matter explain a wealth of observations.
