In eternal inflation theory, runaway cosmic expansion stops only in localized patches, giving birth to isolated 'pocket universes' like our own. Explore how this speculative framework reshapes modern cosmology, why these neighboring realms remain unobservable, and why even an infinite future still required a physical beginning.
NASA’s Hubble Space Telescope has imaged the edge-on spiral galaxy NGC 1827 in Columba. The observation is part of an ongoing multi-orbit survey studying 260 satellite galaxies around 22 Milky Way-like hosts to test and refine small-scale cosmological models.
Dark matter is supported by gravitational evidence, but no particular candidate has been confirmed. Explore what observations reveal, how experiments search, and where uncertainty remains.
