Can a Nucleus Have Four Neutrons and Two Faces?

July 25, 2017 Mbeljac 0

Two cool new results in nuclear physics that promise to extend our understanding of the nucleus have been in the news. The first relates to the possibility of a stable four neutron nucleus, and the second on the relative stability of some light nuclei with deformed shapes occasioned by energy […]

The Signal and the Noise: Revolutionary New Cosmology at LIGO?

July 23, 2017 Mbeljac 0

The discovery of gravitational waves promised to usher in a new age of empirical cosmology, with potentially significant implications for our theoretical understanding of the physical world. Roger Penrose in a new paper is claiming that this promise has been delivered. At issue is “noise” in the signal of gravitational […]
