How medical tests have built-in discrimination against Black people

Researchers have found direct evidence for the existence of an energetic hot wind launched from the hot accretion flow onto a weakly accreting supermassive black hole, representing a step toward understanding accretion processes around black hole.

In the vicinity of black holes, space is so warped that even light rays may curve around them several times. This phenomenon may enable us to see multiple versions of the same thing. While this has been known for decades, only now do we have an exact, mathematical expression.

We Now Have Precise Math to Describe How Black Holes Reflect The Universe
