Latest Tests of general relativity Stories
The rotating black hole has been described as one of nature's most perfect objects.
By Anonymous A study of two unequal mass stars in close orbits has produced results in keeping with Einstein's theory of general relativity.
XMM-Newton has, for the first time, detected signals from both stars of a binary pulsar system in X-rays, unveiling a scientific goldmine. Each star of the closely-packed system is a dense neutron star, spinning extremely fast, radiating X-rays in pulses.
The same team of astrophysicists that cracked the computer code simulating two black holes crashing and merging together has now, for the first time, caused a three-black-hole collision.
For the past three years a satellite has circled the Earth, collecting data to determine whether two predictions of Albert Einstein's general theory of relativity are correct.
Is Earth in a vortex of space-time? We'll soon know the answer: A NASA/Stanford physics experiment called Gravity Probe B (GP-B) recently finished a year of gathering science data in Earth orbit.
Almost 90 years after Albert Einstein first postulated his general theory of relativity, scientists have finished collecting data to put it to a new, different kind of experimental test.
Black holes have a reputation for voraciously eating everything in their immediate neighborhood, but these large gravity wells also affect electromagnetic radiation and may hinder our ability to ever locate the center of the universe, according to an international research team.
A key prediction of Albert Einstein's general theory of relativity has been confirmed by an experiment showing that the Earth's rotation drags the surrounding fabric of space-time along with it. The phenomenon, known as frame-dragging, was one of the last untested predictions of general relativity.
