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

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

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

What cosmological evidence from the Cosmic Microwave Background (CMB) anisotropies observed in 2003 supports the presence of dark matter in the universe?

CMB anisotropies indicate large-scale structure formation, consistent with dark matter's gravitational influence

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

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

What the CMB power spectrum tells us — the age, composition, and geometry of the universe

CMB power spectrum reveals universe's age, composition, and large-scale structure

What type Ia supernovae revealed in 1998 — the expansion of the universe is accelerating, implying dark energy
