Event Horizon
Even our scientific heroes can’t be right about everything. Let’s learn the lessons that they never did. In the 1960s, a young theoretical physicist named Stephen Hawking rose to prominence as […]
If nothing can escape from beneath the event horizon, where do these phenomena come from? The most important feature of a black hole is that it has an event horizon: a […]
Would there be only blackness past the event horizon? Or something more? Black holes are some of the most perplexing objects in the entire Universe. Objects so dense, where gravitation […]
The Event Horizon Telescope has come online and taken its data. Now, we wait for the results. Black holes are some of the most incredible objects in the Universe. There are […]
When matter falls in, black holes grow. But Hawking radiation says that black holes decay. Who wins? “Maybe that is our mistake: maybe there are no particle positions and velocities, but […]
Falling into a black hole is forever… but could a tether to the outside pull you back out? “Nobody ever did, or ever will, escape the consequences of his choices.” –Alfred A. […]
You might think that it should be all black, but then how would we see it? “It is conceptually interesting, if not astrophysically very important, to calculate the precise apparent shape […]
We’ve never seen an event horizon, nor directly imaged a black hole. Thanks to a worldwide effort, victory may at last be in sight. “Never look down to test the ground […]
Merging black holes are some of the most extreme events in the Universe. Could a modified event horizon reveal quantum gravity? “The bedrock nature of space and time and the unification […]
And what are our prospects for observing its event horizon? “Never look down to test the ground before taking your next step; only he who keeps his eye fixed on the […]
