Even Dense Neutron Stars Fall like a Feather
Harnessing the exquisite sensitivity of the National Science Foundation’s Green Bank Telescope (GBT), astronomers have given one of Einstein’s predictions on gravity its most stringent test yet. By precisely tracking the meanderings of three stars in a single system – two white dwarf stars and one ultra-dense neutron star – the researchers determined that even phenomenally compact neutron stars “fall” in the same manner as their less-dense counterparts, an aspect of nature called the “Strong Equivalence Principle.”
