allows us to probe the properties of the black hole itself. We numerically model the appearance of these systems in X-rays (see Fig. 1). While current X-ray observatories cannot directly image the ...

From a classical model and a “one best way” solution to the money problem ... from my perspective it was similar to my failed attempts at explaining Bitcoin to a great-grandparent. One aspect of the ...

The black hole is so enormous that it makes up roughly 40% of the total mass of its host galaxy: in comparison, most black holes in the local universe are roughly 0.1% of their host galaxy mass.

Instead, physicist [Jeff Steinhauer] and colleagues at the Technion-Israel Institute of Technology have developed an acoustic model of black holes, which is what was used to observe the equivalent ...

In 1965, British mathematician Roger Penrose proposed the cosmic censorship conjecture, a concept that suggests that singularities — regions where gravity is so strong that the fabric of ...
