New research on Cepheid variable stars reveals precise distance measurements, shedding light on the universe's scale and resolving discrepancies in cosmological models. Enhanced accuracy in Cepheid measurements helps refine broader cosmic distance markers like supernovae, contributing to our understanding of galactic formations and cosmic expansion.
The Simons Observatory in Chile's Atacama Desert aims to probe the early universe's inflationary period by studying the Cosmic Microwave Background (CMB). Equipped with advanced instruments, it seeks to uncover the mysteries of the Big Bang and primordial gravitational waves, offering profound insights into cosmology.
In a groundbreaking study, scientists discovered that photons, traditionally considered massless, may possess a minuscule mass. This revelation challenges existing physics theories and holds potential for advancements in technology, cosmology, and quantum mechanics.
This article explores the hypothesis that primordial black holes, formed shortly after the Big Bang, could account for dark matter, potentially solving one of the universe's biggest mysteries.
