| Σύνοψη≠ | The Cosmic Microwave Background is the ancient light from when the universe first became transparent, about 380,000 years after the Big Bang. Its tiny temperature variations (anisotropies) across the sky encode a wealth of information about the universe's composition, geometry, and history. First discovered by Arno Penzias and Robert Wilson in 1965, detailed measurements of CMB anisotropies have become the most powerful probe of cosmology. | Baryon Acoustic Oscillations are imprints of sound waves in the early universe that appear as a characteristic scale in the large-scale distribution of galaxies today. First predicted theoretically by Piet Peebles and Joseph Yu in 1970, and detected observationally by the Sloan Digital Sky Survey in 2005, BAO provides a standard ruler for measuring cosmic distances and constraining the expansion history of the universe. |
