Measuring Helium in Distant Galaxies May Give Physicists Insight Into Why the Universe Exists

Gizmodo

When theoretical physicists like myself say that we’re studying why the universe exists, we sound like philosophers. But new data collected by researchers using Japan’s Subaru telescope has revealed insights into that very question.
