ZA_2_08 — Modified Gravity Theories: MOND, f(R), and Alternatives to Dark Matter

Modified gravity theories attempt to explain the "missing mass" problem — the discrepancy between observed gravitational effects and visible matter — without invoking dark matter particles. The most empirically successfu

ZA_2_11 — Spacetime Foam and Quantum Gravity Effects

At the Planck scale — lengths of ~$1.6 \times 10^{-35}$ m and times of ~$5.4 \times 10^{-44}$ s — quantum mechanics and general relativity collide, and the smooth spacetime continuum of Einstein's theory is expected to b

ZA_2_14 — Penrose Twistor Theory: Spinor Geometry and Spacetime

Twistor theory — conceived by Roger Penrose beginning in 1967 — is a radical reformulation of the geometry underlying physics in which the fundamental objects are not points in spacetime but rather twistors: elements of

ZA_2_01 — Time: Physics and Philosophy

Time is arguably the deepest unsolved problem in physics and philosophy. Physics reveals: (1) time is relative, not absolute — Einstein showed it flows at different rates depending on velocity and gravity; (2) the fundam

ZA_2_09 — Wormholes and Exotic Spacetime Geometries

Wormholes — hypothetical tunnels through spacetime connecting distant regions of the universe or even different universes — are exact solutions of Einstein's field equations. First identified by Einstein and Rosen (1935)

ZA_2_03 — General and Special Relativity — Einstein's Revolution

Albert Einstein's two theories of relativity — special (1905) and general (1915) — fundamentally reshaped the understanding of space, time, mass, energy, and gravity. Special relativity, built on Lorentz invariance and t
