Q_1_09 — Fate of the Universe

How will the universe end? This question has moved from philosophy and eschatology into hard physics, driven by the 1998 discovery that the universe's expansion is ACCELERATING (Riess et al. 1998; Perlmutter et al. 1999

Q_4_05 — Modified Gravity Theories

Modified gravity theories propose that the observed discrepancies between luminous matter and gravitational dynamics — traditionally attributed to dark matter — instead result from a breakdown or modification of Newtonia

Q_4_06 — Baryon Asymmetry and Matter-Antimatter

One of the deepest unsolved problems in physics is the baryon asymmetry of the universe — the observed predominance of matter over antimatter. For every ~10⁹ photons in the cosmic microwave background, there is approxima

Q_4_11 — Acoustics: Sound Physics, Resonance, and Wave Phenomena

Acoustics is the science of sound — mechanical pressure waves propagating through matter (gases, liquids, solids). Unlike electromagnetic waves, sound requires a medium and cannot travel through vacuum. Sound is characte

Q_4_01 — Primordial Gravitational Waves and B-Mode Polarization

Primordial gravitational waves — ripples in spacetime generated during cosmic inflation — represent one of the most sought-after signals in cosmology. Their detection would provide direct evidence that inflation occurred

Q_4_32 — The Fundamental Constants: Physics, Life, and Mathematics

The universe runs on numbers — and not arbitrary ones. A small set of fundamental constants, mostly dimensionless, determines every property of matter, energy, space, and time. Change any of them by a fraction and atoms

Q_2_08 — Quasars and Active Galactic Nuclei

Quasars (quasi-stellar objects) and active galactic nuclei (AGN) are the most luminous persistent objects in the universe, powered by accretion of matter onto supermassive black holes (SMBHs, 10⁶–10¹⁰ M☉) at galaxy cente

Q_2_20 — Black Hole Information Paradox & Hawking Radiation

The black hole information paradox is arguably the deepest unsolved problem in theoretical physics, lying at the intersection of general relativity, quantum mechanics, and thermodynamics. In 1974, Stephen Hawking showed
