Controversial Stephen Hawking Predictions, From Evil Aliens to Black Hole Bets

In the 1970s, Stephen Hawking, who died on Wednesday age 76, turned the physics world upside down when he announced that black holes aren’t so black after all, and that some light can in fact escape the singularity’s edge, called the event horizon. That bombshell, which inspired a whole new way of looking at black […]

The Wall of Death Around Black Holes Could Break Down

Physicists have insisted for a long time that black holes are impenetrable ciphers. Whatever goes in is lost, impossible to study or meaningfully understand. Some small amount of matter and energy might escape a black hole in the form of “Hawking radiation,” but anything still inside the black hole is functionally disappeared from the physical […]

Could A Black Hole Be Blocking The Light From That ‘Alien Megastructure’ Star?

About 1480 light-years away from Earth, a star is doing something astronomers have never seen before. Every now and then, at random intervals, its light dips by as much as 22 percent. That’s way too much to be a planet. And the star (officially named KIC 8462852, but informally called “Tabby’s Star” or “Boyajian’s Star”) […]

This Is the Last Thing Japan’s Lost Black Hole Satellite Saw Before It Died

Earlier this year, Japan launched a groundbreaking black-hole-monitoring satellite—only to lose control of it almost immediately under strange circumstances. Now, we finally can see what Hitomi did right before it died. When JAXA launched Hitomi in February of this year, scientists were giddy over the possibilities of what the black hole monitoring satellite might tell […]

Scientists observe huge black hole shred a star, emit x-rays

They’re known as tidal disruption events: when a black hole consumes a nearby star. And now, scientists have observed a dramatic tidal disruption event in a galaxy nearly 4 billion light years away, involving a black hole that’s approximately a million times as massive as our sun. The matter that this supermassive black hole swallowed […]

Latest Space-Time Ripples Confirm New Era of Astronomy

Scientists have directly observed gravitational waves, ripples in the fabric of spacetime, for the second time—confirming the start of a new era of astronomy. Much like the historic first observation announced in February, the second event marked the cataclysmic embrace of two black holes more than a billion years ago. This fatal attraction sent shockwaves […]
