Nothing Escapes From a Black Hole, and Now Astronomers Have Proof (Synopsis) [Starts With A Bang]

“Where we’re going, we won’t need eyes to see.” -Sam Neill, Event Horizon

Are event horizons real? With data taken from around a dozen observatories earlier this year, simultaneously, the Event Horizon Telescope is poised to put together the first-ever direct image of the black hole at the center of our galaxy Sagittarius A*. If event horizons are real, this data should be able to create the first-ever image of it, proving that nothing escapes from inside a black hole once you’ve been swallowed.

But why wait? Through a very clever technique, a team of astronomers used data from the Pan-STARRS telescope to test the alternative: that there’d be a hard surface exterior to where the event horizon is supposed to be. If that were the case, stars that collided with these hard surfaces would create a transient signal in the visible and infrared, which is exactly what Pan-STARRS is sensitive to.

The lack of such signals, even though a significant number would be expected, shows that the alternative to event horizons cannot stand. Event horizons are real, and now we have indirect proof!
