What happens when a black hole destroys a star? New study reveals a chaotic doom

Posted by in category: cosmology

If you’ve ever wondered what happens when something gets sucked into a black hole, now is your opportunity to find out.


This unique look at the disruption of a star explains why astronomers haven’t seen large amounts of high-energy X-rays from this and other similar tidal disruption events.

Black Holes Finally Proven Mathematically Stable

Posted by in categories: cosmology, information science

Unstable black holes would require a rewrite of Einstein’s gravitational theory.

An international group of scientists finally proved that slowly rotating Kerr black holes are stable, a report from Quanta Magazine

In 1963, mathematician Roy Kerr found a solution to Einstein’s equations that accurately described the spacetime around what is now known as a rotating black hole.

NASA have released the sound of a black hole and it’s terrifying

Posted by in category: cosmology

NASA has dropped a remix of what a black hole sounds like — and it’s exactly what you’d expect. The hole in question sits 200 million light-years away in the Perseus galaxy cluster — an 11 million-light-year-wide set of galaxies packed with hot gas. In the clip, you can hear rumbling and groaning which feels fit for an episode of Stranger Things, but it’s actually pressure waves rippling through the hot gas.

Supermassive black hole pair nearest Earth is locked in a violent cosmic dance

Posted by in category: cosmology

At the heart of merging galaxies is the closest pairing of supermassive black holes ever found that will eventually collide and create a larger black hole.

New underground lab to shed light on dark matter

Posted by in categories: cosmology, physics

Half a mile-deep lab is shielded with 100 tons of steel.

A gold mine located over half a mile (one km) underground in Victoria, Australia, has been converted into the Stawell Underground Physics Laboratory to study dark matter, a press release from Australia’s Nuclear Science and Technology Organization (ANSTO) said.

Scientists believe that dark matter, the invisible substance largely unknown to mankind, makes up 85 percent of our universe’s mass. To know more about it, scientists have been building dark matter detectors, and one of the “most sensitive” detectors delivered some significant results last month.
