Supernovae and black holes, although they surprise scientists, are gradually being studied and recorded. Scientists are much more concerned with strange places in the Universe, which are difficult to explain by the laws of physics and nature we know. The Bootes Void is one such place. It is not considered to be emptiness by chance – there is absolutely nothing in it. Astronomers for a long time could not believe their own eyes, because in a colossal area of 300 million light years there was not a single galaxy or star. Solid blackness extends over unimaginable distances. Like anomalien.com on Facebook…

We discuss the possibility to predict the QCD axion mass in the context of grand unified theories. We investigate the implementation of the DFSZ mechanism in the context of renormalizable SU theories. In the simplest theory, the axion mass can be predicted with good precision in the range ma = (2–16) neV, and there is a strong correlation between the predictions for the axion mass and proton decay rates. In this context, we predict an upper bound for the proton decay channels with antineutrinos, τ p → K + ν ¯ ≲ 4 × 10 37 $$ \tau \left(p\to {K}^{+}\overline{
u}\right)\lesssim 4\times {10}^{37} $$ yr and τ p → π + ν ¯ ≲ 2 × 10 36 $$ \tau \left(p\to {\pi}^{+}\overline{
u}\right)\lesssim 2\times {10}^{36} $$ yr. This theory can be considered as the minimal realistic grand unified theory with the DFSZ mechanism and it can be fully tested by proton decay and axion experiments.

And the “Local Bubble” continues to grow in size.

14 million years ago a series of supernovae exploded pushing gas outwards and making a bubble that had conditions ideal for the formation of new young stars that we see around us. These are the findings from researchers at the Center for Astrophysics (CfA) Harvard and Smithsonian, an institutional press release said.

Where did the material come from that created the Big Bang, and what happened in the first instance to create that material?

It depends.

Warp drive. Site-to-site transporter technology. A vast network of interstellar wormholes that take us to bountiful alien worlds. Beyond a hefty holiday wish-list, the ideas presented to us in sci-fi franchises like Gene Roddenberry’s “Star Trek” have inspired countless millions to dream of a time when humans have used technology to rise above the everyday limits of nature, and explore the universe.

NASA’s new X-Ray Observatory will unlock the universe’s most explosive secrets.

The IXPE mission could change our understanding of black holes, nebulae, and supernovas.

Scientists have come closer than ever before to creating a laboratory-scale imitation of a black hole that emits Hawking radiation, the particles predicted to escape black holes due to quantum mechanical effects.

The black hole analogue, reported in Nature Physics¹, was created by trapping sound waves using an ultra cold fluid. Such objects could one day help resolve the so-called black hole ‘information paradox’ — the question of whether information that falls into a black hole disappears forever.

😮 circa 2021.

The fundamental forces of physics govern the matter comprising the Universe, yet exactly how these forces work together is still not fully understood. The existence of Hawking radiation — the particle emission from near black holes — indicates that general relativity and quantum mechanics must cooperate. But directly observing Hawking radiation from a black hole is nearly impossible due to the background noise of the Universe, so how can researchers study it to better understand how the forces interact and how they integrate into a “Theory of Everything”?

Today’s Google Doodle honors the late physicist Stephen Hawking on his 80th birthday. Hawking was a renowned cosmologist, and he spent his career theorizing about the origins of the universe, the underlying structure of reality, and the nature of black holes. But he became a household name for the way he communicated those ideas to the public through books and TV appearances.

“My goal is simple,” he once said. “It is a complete understanding of the universe, why it is as it is and why it exists at all.”

One of Hawking’s best-known ideas is that black holes slowly regurgitate information about all the matter they’ve swallowed — but it comes out in a jumbled form called Hawking radiation. In 1974, Hawking proposed that the event horizon of a black hole emits energy. Because energy can be converted into mass, and vice versa (that’s what Albert Einstein’s famous equation E=mc² tells us), emitting all that energy into space will shrink the black hole. Eventually, it will run out of mass and disappear.
