Major Problem in Physics Could Be Fixed if The Whole Universe Was Spinning : ScienceAlert
Earth rotates, the Sun rotates, the Milky Way rotates – and a new model suggests the entire Universe could be rotating. If confirmed, it could ease a significant tension in cosmology.
The Universe is expanding, but exactly how fast is a…

Influence of topology on the critical behavior of hierarchical modular neuronal networks
Hierarchical network architecture
The ER and KN networks were constructed by first establishing a single module of N neurons. This module is assigned the initial hierarchical level H = 0, and additional modules are progressively created by…
