Stephen Hawking Proposes Radical New Theory of Black Holes
Stephen Hawking has proposed a breakthrough theory in a new paper - the idea that black holes can exist without an event horizon.
In A Brief History of Time, Stephen Hawking described how an unlucky astronaut would be "stretched like spaghetti" and torn apart by the gravitational gradient. Others have argued this unlucky astronaut would be flash-fried by a firewall of energy. To solve this so-called black-hole firewall paradox, a whole cottage industry has popped up of black hole astronaut death theorizers, and at stake is the basis of Einstein's general theory of relativity.
Now Stephen Hawking has proposed a breakthrough theory in a new paper - the idea that black holes can exist without an event horizon. An event horizon is thought to be the boundary through which nothing, including light, can escape. In his paper, playfully entitled "Information Preservation and Weather Forecasting for Black Holes," Hawking argues that "gravitational collapse produces apparent horizons but no event horizons behind which information is lost." (Read the paper here.)
Hawking proposes that an apparent horizon only temporarily holds matter and energy back before eventually releasing them. For an astronaut passing through a black hole, of course, the circumstances surrounding his demise would be purely theoretical.
Hawking's paper is based on a talk he delivered remotely to a conference last year at the Kavli Institute for Theoretical Physics in Santa Barbara, California. You can watch the video of his talk here. In the meantime, Hawking's paper awaits peer review.

The Oxfam report prompted Anand Giridharadas to tweet: "Don't be Pinkered into everything's-getting-better complacency."
- A new report by Oxfam argues that wealth inequality is causing poverty and misery around the world.
- In the last year, the world's billionaires saw their wealth increase by 12%, while the poorest 3.8 billion people on the planet lost 11% of their wealth.
- The report prompted Anand Giridharadas to tweet: "Don't be Pinkered into everything's-getting-better complacency." We explain what Steven Pinker's got to do with it.
Moans, groans, and gripes release stress hormones in the brain.
Could you give up complaining for a whole month? That's the crux of this interesting piece by Jessica Hullinger over at Fast Company. Hullinger explores the reasons why humans are so predisposed to griping and why, despite these predispositions, we should all try to complain less. As for no complaining for a month, that was the goal for people enrolled in the Complaint Restraint project.
Participants sought to go the entirety of February without so much as a moan, groan, or bellyache.
- Facebook and Google began as companies with supposedly noble purposes.
- Creating a more connected world and indexing the world's information: what could be better than that?
- But pressure to return value to shareholders came at the expense of their own users.
