Racism and the black hole of gun control in the US | Racism | Al Jazeera

I will never forget the day in eighth grade when my friend pointed a pistol at my face and pulled the trigger.

I am old enough now that many of my childhood memories have faded into blurry black and white pictures, but 30 years later, that scene is a vivid colour film in my memory.

I can see the smirk in his brown eyes as he points the pistol at my forehead, the slightly blue shimmer of the metal in the afternoon light, the way that the flat side of the barrel reached a nipple of an opening, suddenly curving inward, and the explosion of sound as he pulled the trigger.

Observing 'black hole symphony' using gravitational wave astronomy | NSF - National

Shrouded in mystery since their discovery, black holes continue to be mind-boggling enigmas in our universe.

Limitations in observation technologies have kept scientists from grasping a more complete picture of black holes. One of the largest gaps lies in a certain type of black hole: intermediate-mass black holes that fall between supermassive (at least a million times greater than our sun) and stellar (smaller, though still 5 to 50 times greater than the mass of our sun) black holes.

The biggest scientific discoveries of 2019, in photos - Business Insider

In 2019, scientists around the world pulled off some impressive feats: They imaged a supermassive black hole for the first time, debuted two treatments for the Ebola virus , and launched a spacecraft into orbit that's powered by sunlight alone. 

Over the past year, researchers have also discovered a hidden continent , captured video of a giant squid in its deep-sea habitat, and sent a probe to an asteroid 5.5 million miles from Earth.

Black hole shock: New method to explore black holes explained - 'harnessing its symphony' |

German-born theoretical physicist Albert Einstein first predicted the existence of black holes in 1916, with his general theory of relativity. They remained merely theoretical objects for decades, until the first-ever physical black hole was discovered in 1971.

Then, in 2019 the Event Horizon Telescope (EHT) collaboration released the first image ever recorded of a black hole.

Like a symphony orchestra emits sound across an array of frequencies, the gravitational waves emitted by black holes occur at different frequencies and times

Physicists Finally Find a Way to Tell Certain Black Holes Apart

In the 1960s and '70s, physicists Jacob Bekenstein and John Wheeler did a bit of math and determined that black holes "have no hair."

* * *

Hair is often used to describe how a person looks — he's a blonde, she's a brunette. But Bekenstein and Wheeler determined that black holes didn't have that something scientists could use to describe their appearance.

All black holes have, according to the longstanding theory, are the three observable characteristics defined by Albert Einstein's general theory of relativity: a mass, an angular momentum, and an electric charge. The black hole's gravitational pull snatches up anything else that might be useful for differentiating one black hole from another of the same type.

New Results on Black Hole and Neutron Star X-Ray Binaries From Insight-HXMT

Scientists with the Hard X-ray Modulation Telescope (Insight-HXMT) team presented their new results on black hole and neutron star X-ray binaries during a press conference held Oct. 25 at the first China Space Science Assembly in Xiamen. Credit: IHEP

X-ray binaries are binary stars that emit X-rays and are composed of a normal star and either a neutron star or a black hole. The gravity of the very dense neutron star or black hole causes material from the normal star to fall toward it, creating a rapidly rotating accretion disk that emits intense X-ray radiation. X-ray binaries are an important research target for those trying to understand strong gravitational and magnetic fields and matter affected by them.
