Why special relativity doesn't need the luminiferous aether — the Michelson-Morley null result becomes expected

What the EPR paradox challenged — Einstein argued entanglement implied either hidden variables or nonlocality

EPR paradox questioned quantum mechanics' lack of locality and determinism

Why Einstein needed Riemannian geometry — curved spacetime requires non-Euclidean mathematics

Riemannian geometry underpins general relativity, describing curved spacetime

How Eddington's 1919 eclipse observation confirmed general relativity — starlight bent by the Sun

Eddington's eclipse observation showed starlight bending due to the Sun's gravity, confirming general relativity

Why nothing with mass can reach the speed of light — the Lorentz factor γ diverges as v approaches c

As velocity v approaches c, Lorentz factor γ increases, preventing massive objects from reaching light speed

What the information paradox asks — does information falling into a black hole disappear, violating quantum mechanics

The information paradox questions: Does information vanish in black holes, contradicting quantum theory?

How do the results from LIGO and Virgo collaborations provide evidence for gravitational waves, thereby supporting the predictions of general relativity?

LIGO and Virgo detectors' measurements of gravitational wave signals confirm Einstein's general relativity predictions
