The breakthrough offers new insights into the feeding mechanisms of black holes, from stellar-mass systems like Cygnus X-1 to ...

While considered a mathematical possibility for many years, the first black hole wasn’t discovered until Cygnus X-1 in 1971. We now know that black holes occur frequently throughout the universe.

Working off of Albert Einstein’s theory of gravity, the Australian physicist Ludwig Flamm suggested that a spacetime conduit could connect one side of a hole to the other. While black holes suck ...

This could explain the differences between the black holes at the centre of active galaxies (like Cygnus A) and their less active cousins (like our own Milky Way): the presence or absence of a ...
