What baryon acoustic oscillations are — sound waves frozen in the early universe that set a standard ruler

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 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 string theory proposes — fundamental objects are 1D strings vibrating in 10 or 11 dimensions

String theory posits fundamental objects as 1D strings in 10 or 11 dimensions

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 cosmological constant problem is — quantum field theory predicts vacuum energy 10^120 times too large

Quantum field theory overestimates vacuum energy by 10^120 times, causing the cosmological constant problem
