Doomed Neutron Stars

New Tool Uses Gravitational Waves to Peer Inside Neutron Stars

Credit: NASA’s Goddard Space Flight Center/CI Lab Imagine taking a star with twice the mass of the Sun and crushing it down to the size of Manhattan. The result would be a neutron star—one of the densest objects found anywhere in the Universe. In fact, they exceed the density of any material found naturally on …

Advanced AI discovers a treasure trove of gravitational lenses

Advanced artificial intelligence has identified thousands of possible “gravitational lenses” — warps in space-time predicted by Albert Einstein — promising to enhance our understanding of dark matter and the evolution of galaxies. Einstein realized that mass warps space, and massive galaxies swear galaxy clusters can distort space around them to such a degree that they …

Deciding to Read This Article Isn’t The Result of Gravity Crushing Your Quantum Spirit

A few years ago, deep beneath the Apennine Mountains in Italy, a team of physicists hunted for flashes of light that just might suggest human consciousness is the product of gravitational forces. The fact they came up empty-handed doesn’t mean we’re all meat computers with no free will; it does make the quest for a …
