In a new Physical Review Letters (PRL) study, scientists explore the possibility of nontrivial or exotic topologies in the universe for explaining some of the anomalies seen in Cosmic Microwave ...
The cosmic microwave background (CMB) provides a snapshot of the Universe 380,000 years after the Big Bang, revealing minute temperature fluctuations—anisotropies—that trace the primordial density ...
Cosmic microwave background (CMB) lensing refers to the subtle deflection of primordial photons by the gravitational influence of intervening matter as they travel from the surface of last scattering ...
