nasa glenn, why hydrogen?, https://www1.grc.nasa.gov/wp-content/uploads/asme-report-on-rl-10-1970s.pdf (about 76% of the weight of the universe's matter)., nasa science, universe glossary (https://science.nasa.gov/universe/glossary/); nasa genesis educational module, the modern periodic table (https://solarsystem.nasa.gov/genesismission/educate/scimodule/cosmic/explore_2st.pdf)., nasa/astrophysics consensus: hydrogen constitutes roughly 74% of baryonic (ordinary) matter mass in the universe, the largest share of any element, per standard cosmic abundance tables (e.g. nasa's cosmicopia / big bang nucleosynthesis figures)., nasa/big bang nucleosynthesis cosmic abundance data (standard astrophysics reference: hydrogen ~74% of baryonic mass, helium ~24%, remaining elements <2%), nasa/caltech cool cosmos and standard astrophysics references (e.g. wikipedia "abundance of the chemical elements") state hydrogen is ~74% of baryonic mass in the universe, making it the most abundant element by mass, nasa/caltech cool cosmos and standard astrophysics references state hydrogen makes up about 74% of the baryonic mass of the universe, followed by helium at about 24%, nasa/caltech cool cosmos and standard cosmochemistry references state hydrogen makes up roughly 74% of the mass of ordinary matter in the universe, followed by helium (~24%), with all other elements a small remainder, nasa/goddard space flight center imagine the universe (https://imagine.gsfc.nasa.gov/science/questions/elements.html) and nasa's baryonic composition summaries state hydrogen makes up about 74% of the universe's elemental mass, followed by helium at about 24-25%, with hydrogen being the most abundant element by mass, nasa/standard astrophysics reference (e.g. nasa cosmicopia / textbook cosmic elemental abundance tables): hydrogen is approximately 74% of baryonic mass in the universe, followed by helium (~24%), all other elements combined being a small remainder, nasa/standard astrophysics reference (e.g., nasa goddard/wikipedia 'abundance of the chemical elements'): hydrogen makes up roughly 74% of baryonic mass in the universe, more than any other element., nasa/standard astrophysics reference: baryonic matter in the universe is approximately 74% hydrogen and 24% helium by mass, making hydrogen the most abundant element by mass., nasa/standard astrophysics references (e.g. nasa cosmic composition summaries, codata/astronomy textbooks) state hydrogen makes up roughly 74% of all baryonic (ordinary) mass in the universe, with helium a distant second at about 24-25%, making hydrogen the most abundant element by mass, nasa/standard astrophysics references (e.g. nasa goddard cosmochemistry summaries, textbook big bang nucleosynthesis figures) consistently give hydrogen as ~74% of ordinary (baryonic) matter by mass, with helium second at ~24-25%; this is a well-established, unchanging physical fact not dependent on the on-chain window, nasa/standard astrophysics references (e.g. nasa goddard, chandra x-ray observatory, and standard astronomy textbooks) state hydrogen is roughly 75% of baryonic mass in the universe, with helium about 24% and all heavier elements about 1%, nasa/standard astrophysics references (e.g. nasa science pages and cosmochemistry textbooks) state that hydrogen is the most abundant element in the universe by mass (~74%), followed by helium (~24%), nasa/standard astrophysics references (e.g., nasa goddard cosmic abundance summaries) state hydrogen is roughly 74% of the universe's baryonic mass, with helium a distant second (~24%), making hydrogen the most abundant element by mass., nasa/standard astrophysics references (e.g., nasa goddard, wikipedia 'abundance of the chemical elements') state hydrogen constitutes roughly 73-75% of the universe's baryonic mass, the largest share of any element, with helium second (~24-25%), ntrs.nasa.gov, periodic.lanl.gov, science.gsfc.nasa.gov, science.nasa.gov, webelements, hydrogen: geological information, https://winter.group.shef.ac.uk/webelements/hydrogen/geology.html, www1.grc.nasa.gov, www2.lbl.gov
