Motion of satellite galaxies suggests younger universe
Jan 23, 2024 (Nanowerk News) In standard cosmological models, the formation of cosmological structures begins with the emergence of small structures, which subsequently undergo hierarchical merging, leading to the formation of larger systems. As the Universe ages, massive galaxy groups and clusters, being the largest systems, tend to increase in...
NIL Metalens array enabling next-generation true-3D near-eye displays
Jan 23, 2024 (Nanowerk News) Integral imaging (II) display is one of the most promising near-eye displays (NEDs) due to its compact volume, full parallax, convenient full-color display, and, more importantly, true-3D and more realistic depth perception from eliminating the vergence-accommodation conflict (VAC). However, II displays based on the conventional...
