New Method to Precisely Measure Strong Interaction Between Nucleons

Within the atomic nuclei, the positively charged protons should, in fact, repel each other. However, even heavy nuclei with numerous neutrons and protons stay bound together. This is feasible due to the so-called strong interaction.

A Technique to Sift Out the Universe’s First Gravitational Waves

In the moments immediately following the Big Bang, the very first gravitational waves rang out. The product of quantum fluctuations in the new soup of primordial matter, these earliest ripples through the fabric of space-time were quickly amplified by inflationary processes that drove the universe to explosively expand.
