It is known that the cosmic web in general and filaments, in particular, are intimately connected with galaxy formation and evolution 15, 16. Yet, owing to the challenges in characterizing and identifying such objects, potential rotation on the scales of cosmic filaments has been discussed 14 but never measured until now. Regions that are still in the linear or quasilinear phase of collapse could provide a better stage for the application of tidal torque theory.Ĭosmic filaments 13, being quasilinear extended topographical features of the galaxy distribution, provide such an environment. Although one recent study 12 has demonstrated that galaxy spin direction (that is, clockwise versus anticlockwise) can be predicted from initial conditions, revealing a critical clue to the nonlinear acquisition of angular momentum, our understanding of spin magnitude, direction and history remains in its infancy. As a collapsing region reaches turnaround, tidal torques cease to be effective and the final angular momentum of a collapsed region is far from what tidal torque theory would predict 9, 10, 11. Such an explanation is valid only in the linear regime, namely in the limit where density perturbations are small with respect to the mean and where flows are laminar. Tidal torque theory 1, 2, 3, 4, 5, 6, 7, 8, 9 provides one explanation-the misalignment of the inertia tensor of a gravitationally collapsing region of space with the tidal (shear) field can give rise to torques that spin up the collapsing material 1, 3, 8. Such a potential flow is irrotational or curl free: there is no primordial rotation in the early Universe and angular momentum must be generated as structures form. In the standard model of structure formation, small overdensities present in the early Universe grow via gravitational instability as matter flows from under- to overdense regions. How angular momentum is generated in a cosmological context is one of the key unsolved problems of cosmology. These results signify that angular momentum can be generated on unexpectedly large scales. In addition, the more massive the haloes that sit at either end of the filaments, the more rotation is detected. Filament rotation is more clearly detected when viewed edge-on. The strength of the rotation signal is directly dependent on the viewing angle and the dynamical state of the filament. By stacking thousands of filaments together and examining the velocity of galaxies perpendicular to the filament’s axis (via their redshift and blueshift), we find that these objects too display vortical motion consistent with rotation, making them the largest objects known to have angular momentum. Here we investigate the possibility that filaments of galaxies-cylindrical tendrils of matter hundreds of millions of light years across-are themselves spinning. The insights uncovered through our efforts will inform more tailored initiatives and programs to support the female population as they age.Although structures in the Universe form on a wide variety of scales, from small dwarf galaxies to large super clusters, the generation of angular momentum across these scales is poorly understood. The education level positively predicted the propensity toward a growth mindset 2) The living arrangement of cohabitation positively predicted cosmic transcendence and the arrangement of living alone positively predicted the need for solitude and 3) The frequency of attending elderly learning activities correlated positively with age, living arrangement of cohabitation, and growth mindset, but negatively with the education level. Our survey-based analysis ( N = 209) found the following: 1) The propensity toward a growth mindset could predict positively gerotranscendence, cosmic transcendence, coherence, while the lower propensity toward a growth mindset predicted the need for solitude.
The objective of the current study is to examine the mindset, lifelong learning, and gerotranscendence of Taiwanese elderly women, the relationships between them, and additional demographic factors that may impact these variables.
