•4He always
has an abundance of about 23-25%, and there are
traces of D, 3He, and 7Li. No heavier elements because no stable
isotopes with mass numbers 5 and 8. [Need stars, and triple-α process.]
•4He is
always observed to be > 23%.
•D, other light trace
elements, are destroyed in stars, not
created.
•These
results are remarkable and important!
