The Cosmic Mystery | The Accelerating Cosmos: Dark Energy or Alternative Cosmology?

Описание: The Cosmic Mystery: Unraveling Dark Energy
The universe is expanding—and that expansion is accelerating. This documentary explores what might be powering cosmic acceleration: dark energy in the Lambda CDM standard model or alternatives that reach beyond standard cosmology. We revisit the Big Bang and the growing cosmic web, then trace evidence across distant supernova light, the cosmic microwave background, baryon acoustic oscillations, weak gravitational lensing, galaxy clustering, redshift surveys, and structure formation. Along the way we connect the cosmological constant, evolving dark energy and quintessence, modified gravity ideas such as scalar tensor and f R, braneworld and massive gravity proposals, MOND inspired approaches, dark matter halos, cosmic voids, the Hubble constant tension, simulations, and machine learning driven analysis. We also look ahead to how the Vera C Rubin Observatory LSST, Euclid, the Nancy Grace Roman Space Telescope, DESI, JWST deep fields, Planck legacy maps, and standard sirens from gravitational waves can test whether acceleration is a property of space itself or a sign that our understanding of gravity on the largest scales needs an upgrade.
