Q_1_08 — Observable Universe and Cosmic Web
The observable universe has a diameter of ~93 billion light-years (comoving distance) and contains an estimated 2 trillion galaxies (Conselice et al. 2016), ~10²⁴ stars, and ~10⁸⁰ atoms. But its most striking feature is
Q_1_14 — Vacuum Energy and the Cosmological Constant Problem
The cosmological constant problem is widely regarded as the most severe fine-tuning problem in all of physics. Quantum field theory predicts that the vacuum of spacetime is not empty but seethes with zero-point fluctuati
Q_1_24 — Cosmic Microwave Background Deep Analysis
The Cosmic Microwave Background (CMB) is the oldest observable electromagnetic radiation in the universe — thermal radiation released approximately 380,000 years after the Big Bang (redshift z ≈ 1,100) when the universe
Q_1_11 — Cosmological Redshift and the Hubble Law
The discovery that distant galaxies' light is systematically shifted toward longer (redder) wavelengths was the first observational evidence that the universe is expanding. Vesto Slipher's spectroscopic measurements (191
Q_1_03 — Ancient Cosmologies Compared: How Civilizations Understood the Universe
Every civilization on Earth constructed a cosmology — a model of how the universe began, how it is structured, and how it will end. What is remarkable is not the differences but the convergences: primordial waters as the
Q_1_13 — Cosmic Strings and Topological Defects
Cosmic strings are one-dimensional topological defects that may have formed during symmetry-breaking phase transitions in the early universe, analogous to cracks in ice or vortex lines in superfluids. Predicted by Kibble
Q_1_10 — Cosmic Inflation and the First Second
Cosmic inflation — the hypothesis that the universe underwent an exponential expansion in the first 10⁻³⁶ to 10⁻³² seconds after the Big Bang — was proposed by Alan Guth in 1981 to resolve critical problems in standard B
Q_1_01 — The Anthropic Principle & Fine-Tuning of the Universe
The universe appears to be astonishingly fine-tuned for the existence of complex life. Alter the cosmological constant by 1 part in 10¹²⁰, or the strong nuclear force by 0.5%, or the ratio of electromagnetic to gravitati
Q_1_20 — Fractal Cosmology: Is the Universe Self-Similar Across Scales?
The observable universe organises matter into a staggering fractal-like web of galaxy filaments, walls, voids, and clusters — structures visible at scales from 1 Mpc (galaxy groups) to 600 Mpc (the Hercules-Corona Boreal
Q_4_09 — Statistical Mechanics: Boltzmann, Ensembles, and Thermodynamic Emergence
Statistical mechanics is the bridge between the microscopic world of atoms and molecules (governed by classical or quantum mechanics) and the macroscopic world of thermodynamics (governed by temperature, pressure, entrop
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_02 — Gravitational Wave Astronomy
Gravitational waves — ripples in spacetime predicted by Einstein's general relativity (1916) and first directly detected by LIGO (Laser Interferometer Gravitational-Wave Observatory) on September 14, 2015 (event GW150914
Q_4_08 — String Theory: Landscape, Extra Dimensions, and M-Theory
String theory is the leading candidate for a unified theory of all fundamental forces and particles — a framework in which the fundamental entities are not point particles but tiny, one-dimensional vibrating strings (ope
Q_4_04 — Neutrino Astronomy and Neutrino Mass
Neutrinos — nearly massless, electrically neutral leptons that interact only via the weak nuclear force and gravity — are among the most abundant particles in the universe (~330/cm³ relic neutrinos from the Big Bang) yet
Q_4_07 — Entropy: Order, Disorder, and the Arrow of Time
Entropy is one of the most fundamental and far-reaching concepts in all of physics — a quantity that measures the number of microscopic configurations (microstates) consistent with a system's macroscopic properties (macr
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_13 — Classical Mechanics: Newton, Lagrange, Hamilton, and the Action Principle
Classical mechanics — the study of the motion of bodies under the action of forces — is the oldest and most mature branch of physics, tracing from Galileo's kinematics (1638) and Newton's three laws and universal gravita
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_15 — Magnetism: From Lodestones to MRI, Domains to Spin
Magnetism — the force exerted by magnets and electric currents, and the response of materials to magnetic fields — has been known since antiquity (the lodestone, a naturally magnetized iron ore, was used in Chinese compa
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
