Two University of Hawaii at Manoa researchers have identified and corrected a subtle error that was made when applying Einstein’s equations to model the growth of the universe.
Wednesday, August 21st 2019, 8:45 pm – Astronomers detect gravitational waves that may point to a colossal collision
How are black holes born? Astrophysicists have theories, but we don’t actually know for certain. It could be massive stars quietly imploding with a floompf, or perhaps black holes are born in the explosions of colossal supernovas. New observations now indicate it might indeed be the latter.
The incredible space event happened about 900 million years ago.
Observations of light coming from a star zipping in orbit around the humongous black hole at the center of our galaxy have provided fresh evidence backing Albert Einstein’s 1915 theory of general relativity, astronomers said on Thursday.
Albert Einstein’s theory of general relativity, which suggests that gravity is due to the curvature of space and time, is more than 100 years old. And it’s holding up as researchers analyze the behavior of gravity in space — but it may not last forever, according to a new study.
This supermassive black hole weighs approximately 250 million times more than the Sun
The Hubble Space Telescope, which is operated by NASA and the ESA, is fantastic for spotting objects residing in the distant reaches of space. Black holes, which are impossible to actually see, give their position away thanks to the galaxies that often surround them, but a new survey has revealed a black hole with a disc of material that, according to what we think we know about black holes, shouldn’t even be there.
Black holes have traditionally been believed to have formed exclusively from stellar remnants. New indirect evidence suggests otherwise.
Black holes are engines of destruction on a cosmic scale, but they may also be the bringers of life.
