What gravitational time dilation means — clocks run slower in stronger gravitational fields

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 GPS satellites must correct for both special and general relativistic effects — or positions drift by 10 km/day

GPS satellites account for relativistic effects to ensure precise positioning, averting a daily drift of approximately 10 km

What the Kerr solution adds — spacetime around a rotating black hole, including frame-dragging

Kerr solution describes rotating black holes' spacetime, featuring frame-dragging effects

What the equivalence principle says — being in a gravitational field is locally indistinguishable from acceleration

Equivalence Principle: Gravity mimics acceleration, indistinguishable locally

What gravitational lensing confirms — mass curves spacetime and bends the path of light

Gravitational lensing confirms that mass warps spacetime, bending light's trajectory

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
