On Thursday, astronomers announced the first observations of the effect of a black hole’s gravitational redshift — light coming from a star in the gravitational field near a black hole looked redder than it would’ve outside the black hole’s influence.
The black hole responsible was Sagittarius A* (pronounced “Sagittarius A-star�), the supermassive black hole at the center of our M ...read more
Astronomers have long had their eye on a group of stars that precariously circles just outside the supermassive black hole at the heart of our Milky Way galaxy. And, in a discovery announced by the European Southern Observatory on Thursday, scientists say they've finally spotted one of these stars as it travels through the black hole’s gravitational field. It's the first test of Albert Einstein's theory of general relativity near a supermassive black hole.
The event, recorde ...read more
High winds are the norm at the center of the Milky Way. Astronomers have now clocked suns orbiting the galactic core at a staggering 3,000 miles (4,800 kilometers) per second. At this rate, Earth would complete its orbit around the sun in a mere three days. What lurks at the galaxy’s core that can accelerate stars to such speeds?
Astronomers have considered various possibilities. Does the center of the galaxy harbor a tight cluster of superdense stellar remnants (neutron sta ...read more
Entrepreneurs are wired different than the rest of us. They’ll embrace huge financial risk to start a business despite statistics showing most startups fail.
That chutzpa often gets tied to environmental factors, like how they were raised or where they went to college, or even to an X factor — something unknown but all-important that allows them to accept risk without flinching. Other studies have even hinted at a genetic component to risk-taking, or sensat ...read more
In an eyebrow-raising new paper, neuroscientists report that they had participants wear a ball gag while watching images of people in pain. The lucky participants in this neuro-bondage were all female BDSM submissives, and their brain activity in response to the painful pictures was recorded with EEG.
Here's the article: Embodiment and Humiliation Moderation of Neural Responses to Others' Suffering in Female Submissive BDSM Practitioners
And here's some of the stimuli (I assume they we ...read more
