EVENT HORIZON

First reminder.  Albert Einstein correctly called this over a century ago.

Mankind has now something it has never seen before: an image of "the most mysterious objects in the universe"—the black hole. On Wednesday, six simultaneous press conferences were held around the globe, in Washington, Brussels, Santiago, Shanghai, Taipei, and Tokyo, reports Reuters. There, researchers shared the first result of the Event Horizon Telescope project, which in 2017 swiveled a network of radio telescopes worldwide to focus on the center of the galaxy Messier 87, or M87. "We now have visual evidence for a black hole," they announced. Per a tweet from the Event Horizon 'Scope, "The image shows a bright ring formed as light bends in the intense gravity around a black hole that is 6.5 billion times more massive than the Sun."

Second reminder.  Sometimes science takes people to places that they'd really rather not visit.

"The image offered a final, ringing affirmation of an idea so disturbing that even Einstein, from whose equations black holes emerged, was loath to accept it. If too much matter is crammed into one place, the cumulative force of gravity becomes overwhelming, and the place becomes an eternal trap, a black hole. Here, according to Einstein’s theory, matter, space, and time come to an end and vanish like a dream."
