Even phenomenally dense neutron stars fall like a feather
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.'
