Binary pulsar-white dwarf star system  Researchers studying a
distant binary system of a pulsating neutron star and a white
dwarf proved that Einstein's General Relativity calculations
hold up even in extreme gravitational conditions. (European
Southern Observatory)  Albert Einstein has been dead for nearly
60 years, relatively speaking, and he’s still being tested.
Theoretically, at least.  General relativity, the theory for
which the German-born theoretical physicist is best known, holds
up even in the more outlying phenomena of distant space,
scientists have found.  Astronomers studied a neutron star about
7,000 light years from Earth that is twice as heavy as our sun
but only about 12 miles in diameter. The gravity of this
spinning, highly magnetic star, or pulsar, is about 300 billion
times stronger than the force that’s holding your feet to the
ground. A companion white dwarf is what remains of a much
lighter star that is dying out.  The tightly spaced pulsar-dwarf
pair, rotating around each other in un
