(Phys.org)—Astrophysicists Adrian Melott and Brian Thomas of the University of Kansas and Washburn University respectively, have published a "brief communication arising" piece in the journal Nature suggesting that the ...
(PhysOrg.com) -- Neutrons, the particles that along with protons, exist in the nuclei of atoms (except for hydrogen) have been intensely studied ever since their discovery in the 1930’s. And while many interesting developments ...
The first stars of the universe were monstrous beasts. Comprised only of hydrogen and helium, they could be 300 times more massive than the sun. Within them, the first of the heavier elements were formed, then cast off into ...
