What is the origin of dark energy? Scientists reach possible answer

Posted by in category: cosmology

Astronomers have possibly found evidence that dark energy — associated with accelerating the expansion of our universe — could also be related with the mysterious black holes.

About 70% of our universe roughly comprises of dark energy and is believed to have born after the Big Bang, around 13.8 billion years ago, though the origin of the force remains unclear, according to LiveScience.

Recently, some astronomers proposed a theory that dark energy could have emerged from the core of gigantic dark abyss called the black holes while others disagreed with the theory.

Hubble watches neutron stars collide and explode to create black hole and ‘birth atoms’

Posted by in categories: cosmology, particle physics

“We can now see the moment where atomic nuclei and electrons are uniting in the afterglow,” team member Rasmus Damgaard, a researcher at the Cosmic DAWN Center, said in a statement. For the first time, we see the creation of atoms, we can measure the temperature of the matter, and we can see the microphysics in this remote explosion.”

“It is like admiring three cosmic background radiation surrounding us from all sides, but here, we get to see everything from the outside. We see before, during, and after the moment of birth of the atoms.”

Neutron stars are born when stars at least 8 times as massive as the sun exhaust their fuel for nuclear fusion and can no longer support themselves against their own gravity.

Science may have found its first dark-matter detector

Posted by in categories: cosmology, science

Scientists in Virginia are looking for mysterious dark matter — and have turned to really old rocks.

The substance, which makes up more than 80 percent of all matter in the universe, shapes and affects the cosmos. But it is entirely invisible and remains undetectable by normal sensors and techniques.

Analyzing billion-year-old rocks, researchers at Virginia Tech hope to find traces of dark matter. The idea was first proposed in the 1980s. Technological advances since then led them to revisit the idea. What if there were traces in Earth’s minerals?

Black holes could be driving the expansion of the universe, new study suggests

Posted by in category: cosmology

A radical hypothesis suggesting black holes could be behind the accelerating expansion of our universe has been stirring up controversy among astronomers. A new study may contain the first tantalizing hints it could be real.

See my new paper proved that rotating blackhole could create stable wormhole and how to build stargates

Posted by in categories: cosmology, particle physics, quantum physics

https://lnkd.in/gPGP3Q3j In this article, we propose a new Feynman’s path integral approach and extend this formalism into curved spacetime and consider its possible implications for black hole physics. While still a work in progress, this model suggests that black holes, rather than representing the final stages of gravitational collapse, might contribute to the formation of new universes. We carefully examine both Schwarzschild and Kerr metric of rotating and non-rotating black holes. We derived that rotating black hole will create a traversable worm hole without exotic particles and non-rotating back hole will create another universe by interpretation of path integral finally. We proposed the way how to create the wormhole between two interstellar space using qubits. This proved ER=EPR. John Preskill Dear Professor Preskill Please help me check it Sir.

Cosmic Inflation Explained | Cosmology 101 Episode 6

Posted by in categories: cosmology, physics

In this episode of Cosmology 101, we learn how the detection of the Cosmic Microwave Background (CMB) validated the Big Bang Theory and led to the development of the concept of cosmic inflation.

Explore the challenges and ongoing debates in cosmology as scientists seek to uncover the true nature of the early universe and the origins of cosmic structure.

Study links black holes to dark energy

Posted by in category: cosmology

Almost 14 billion years ago, at the very beginning of the Big Bang, a mysterious energy drove an exponential expansion of the infant universe and produced all known matter, according to the prevailing inflationary universe theory.

Physicists Think The Infinite Size of The Multiverse Could Be Infinitely Bigger

Posted by in categories: cosmology, quantum physics

Not only does God play dice, that great big casino of quantum physics could have far more rooms than we ever imagined. An infinite number more, in fact.

Physicists from the University of California, Davis (UCD), the Los Alamos National Laboratory in the US, and the Swiss Federal Institute of Technology Lausanne have redrawn the map of fundamental reality to demonstrate the way we relate objects in physics could be holding us back from seeing a bigger picture.

For about a century, our understanding of reality has been complicated by the theories and observations that fall under the banner of quantum mechanics. Gone are the days when objects had absolute measures like velocity and position.

Revealing the hidden universe with full-shell X-ray optics

Posted by in category: cosmology

The study of X-ray emission from astronomical objects reveals secrets about the universe at the largest and smallest spatial scales. Celestial X-rays are produced by black holes consuming nearby stars, emitted by the million-degree gas that traces the structure between galaxies, and can be used to predict whether stars may be able to host planets hospitable to life.
