The post describes a high-precision study using the Large Binocular Telescope on 15 pristine dwarf galaxies to measure primordial helium abundance, improving accuracy from 2% to 0.5% uncertainty by analysing multiple spectral lines.
This result aligns precisely with Big Bang nucleosynthesis predictions, confirming exactly three neutrino families in the early universe without requiring extra particles.
The work turns observations of ancient, chemically untouched gas into a 13.8-billion-year-old t...
