The precursors of heavy elements might arise in the plasma underbellies of swollen stars or in smoldering stellar corpses.

What we saw in the DESI experiments, and now strengthened by our South Pole Telescope observations, is that dark energy is ...

Richard Feynman, a famous theoretical physicist who won the Nobel Prize, said that if he could pass on only one piece of ...

Modern re-run shows that Arthur Ruhlig’s conclusions, which probably influenced early thinking about fusion energy, were ...

Jun 03, 2025 Memory matters for quantum atomic motion on metals New method simulates electronic friction effects on quantum motion, explaining hydrogen diffusion on copper with relevance to catalysis ...

Even when they are in their lowest possible electronic energy level (i.e., the electron's ground state), these two nuclei can still rotate and vibrate, producing a wide range of rovibrational states.

At some point during the dawn, the first stars shone brightly enough to prevent hydrogen nuclei from recombining with electrons into neutral atoms, ending the dark ages for good.

The Sun uses a “too big to fail” fusion regime—its sheer mass (330,000 times more than that of the Earth) is enough to fuse hydrogen nuclei into helium.

Hydrogen-like ions, i.e. atomic nuclei to which only a single electron is bound, are theoretically particularly easy to describe. In the case of heavy nuclei with a high proton number – bismuth ...
