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

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 did the Pound-Rebka experiment of 1959 provide empirical evidence for the gravitational redshift predicted by general relativity?

Measured redshift of gamma rays in Earth's gravitational field confirmed gravitational redshift

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

What the Penrose-Hawking singularity theorems prove — singularities are inevitable in general relativity under certain conditions

Theorems assert black holes and singularities arise from gravitational collapse in spacetime

What the Schwarzschild solution describes — spacetime geometry around a non-rotating spherical mass

The Schwarzschild solution describes the spacetime geometry around a non-rotating spherical mass

What the Einstein field equations relate — the curvature of spacetime (Gμν) to the energy-momentum tensor (Tμν)

Einstein's field equations: Gμν = 8πTμν, relating spacetime curvature to energy-momentum
