What Would Happen if You Fell Into a Black Hole? | Astronomy.com

Sorry, science fiction fans. You can’t actually survive a trip through a black hole. And if you tried to take a plunge into one, like Matthew McConaughey in the movie Interstellar , you’d be ripped apart long before you could find out what’s on the other side.

To fully appreciate why you can’t just swan dive or pilot your spaceship into a black hole, you must first understand the basic properties of these gravitational goliaths. Simply put, a black hole is a place where gravity is so strong that no light — or anything else, for that matter — can escape.

Many things are taking place:

Here's what would happen if a wormhole fought a black hole

Singularities – also known as black holes – are so powerful that even light cannot escape their grasp. But what happens when a black hole meets something even stronger, like a wormhole?

We know a black hole would win in a fight against Godzilla, Earth's yellow sun, and even the entire Milky Way. But a wormhole? That's a tall order. Sure, wormholes are only hypothetical so they're at a disadvantage against black holes – which we've actually observed. However that might be the black hole's only advantage.

Black holes are hiding movies of the universe in their glowing rings | New Scientist

THE picture was seen by billions: a hazy ring, glowing orange-bright, surrounding a heart of darkness. The work of many minds over decades, it was above all a tribute to the brilliance of one. Yet as the world marvelled at the first ever direct image of a black hole – one of the cosmic monsters predicted by Albert Einstein’s theories – the researchers behind it found themselves confronted with a rather basic puzzle.

“After the result was published, we were all getting together and asking: what does this thing mean?” says radio astronomer Michael Johnson at Harvard University. They had been so wrapped up in turning their data into a picture that no one had really stepped back and tried to digest what it was telling them.

Mistaken identity? Researchers uncover true nature of monster black holes | Space

Over two dozen misidentified supermassive black holes have finally been revealed in a new, sky-scanning study.

A team of researchers led by Erini Lambrides of Johns Hopkins University (JHU) in Baltimore, Maryland has spotted 28 supermassive black holes that have been masquerading as other cosmic objects using a host of telescopes including NASA's Chandra X-ray Observatory , Hubble Space Telescope and Spitzer Space Telescope . The team observed these black holes which lie 5 billion light-years or more away within the Chandra Deep Field-South (CDF-S), the deepest X-ray image ever taken.

A New State of Matter --"Black Hole Physics of Strange Metals" | The Daily Galaxy

Home » Physics » A New State of Matter –“Black Hole Physics of Strange Metals”

* * *

“The fact that we call them strange metals should tell you how well we understand them. Strange metals share remarkable properties with black holes, opening exciting new directions for theoretical physics,” says Olivier Parcollet , a senior research scientist at the Flatiron Institute’s Center for Computational Quantum Physics (CCQ) , about the quantum world of metals that dissipate energy as fast as they’re allowed to under the laws of quantum mechanics.

Lighthouse Club battles to fill £1m funding black hole | Construction Enquirer News

The charity launched a crisis appeal in April as fund-raising events across the country were cancelled.

That has currently raised £500,000. But the charity needs more as demand for its services continues to grow.

Lighthouse chiefs have published their latest annual report showing £723,000 was given to families in need last year with nearly another £500,000 spent on education, training and a helpline app.

The 24/7 Construction Industry Helpline has seen a 57% rise in demand answering 2,615 calls for help.
