Colliding Stars May Create Black Holes

A new report in The Astrophysical Journal claims that two stars may have just collided to create a black hole. If this is true, it may radically alter our understanding of how these super structures are formed. The alternative is potentially just as crazy sounding, that two neutron stars can fuse. Either way, something very […]

Stephen Hawking, One of the World’s Brilliant Minds, has died.

ARTICLE VIA BBC NEWS 

World renowned physicist Stephen Hawking has died at the age of 76.

He died peacefully at his home in Cambridge in the early hours of Wednesday, his family said.

The British scientist was famed for his work with black holes and relativity, and wrote several popular science books including A Brief History of Time.

At the age of 22 Prof Hawking was given only a few years to live after being diagnosed with a rare form of motor neurone disease.

The illness left him in a wheelchair and largely unable to speak except through a voice synthesiser.

In a statement his children, Lucy, Robert and Tim, said: “We are deeply saddened that our beloved father passed away today.

“He was a great scientist and an extraordinary man whose work and legacy will live on for many years.”

They praised his “courage and persistence” and said his “brilliance and humour” inspired people across the world.

“He once said, ‘It would not be much of a universe if it wasn’t home to the people you love.’ We will miss him forever.”

A book of condolence has been opened at Gonville and Caius College in Cambridge, where Prof Hawking was a fellow.

Is the ‘origin’ of Life a Natural Consequence of Physics?

Following on from his appearance in Dan Brown’s latest novel ‘Origin’, Jeremy English publishes more research on his hypothesis that ‘life’ is a natural consequence of the laws of physics. Original post via The Space Academy.

A few years back, a remarkable new hypothesis made its way into the scientific zeitgeist – namely, that life is an inevitable consequence of physics. The author of this concept, an associate professor of biophysics at MIT named Jeremy England, has now published the first major papers testing out this idea, and it’s looking like he might be right on the money.

England’s hypothesis is a key bridge between physics and biology. Although it’s not yet conclusively proven, it potentially holds the key to answering one of the greatest questions of all: Where did we come from?

Here’s what his work is arguing. Thanks to the second law of thermodynamics, the universe is heading towards a state of complete structural disorder. It’s tumbling towards a state where everything is essentially the same no matter how the constituent parts are arranged. READ MORE…

Could We Be Wrong About Gravitational Waves?

“In 2010, Erik Verlinde surprised the world with a completely new theory of gravity. According to Verlinde, gravity is not a fundamental force of nature, but an emergent phenomenon. In the same way that temperature arises from the movement of microscopic particles, gravity emerges from the changes of fundamental bits of information, stored in the very structure of spacetime.”

Could the Future be Influencing the Past?

Original article via Science Alert

One of the weirder aspects of quantum mechanics could be explained by an equally weird idea – that causation can run backwards in time as well as forwards.

What Einstein called “spooky” action at a distance could theoretically be evidence of retrocausality, which is the particle equivalent of you getting a stomach ache today thanks to tomorrow’s bad lunch.

Science Ideas Behind Anomaly by Caitlin Lynagh (reblogged)

Ok, so please accept my apologies, this blog has turned into an essay and it has been a long time coming. I’ve wanted to write about the ideas behind the science concepts and suggestions which feature in my book Anomaly (The Soul Prophecies) now for a while, but you know, life gets in the way, […]

Time Crystals: A New state of Matter

Sorry it’s been quiet here for a while. Exam season slows us down a little.

Original article via Science Alert

It’s official: time crystals are a new state of matter, and now we can create them – ScienceAlert:

Earlier this year, physicists had put together a blueprint for how to make and measure time crystals – a bizarre state of matter with an atomic structure that repeats not just in space, but in time, allowing them to maintain constant oscillation without energy.

Two separate research teams managed to create what looked an awful lot like time crystals back in January, and now both experiments have successfully passed peer-review for the first time, putting the ‘impossible’ phenomenon squarely in the realm of reality. More…
