Bridging the Chasm Between Quantum Physics and the Theory of Gravity — “We Have Found a Surprisingly Simple Solution”

Posted by in categories: cosmology, mathematics, quantum physics

Quantum information theory: Quantum complexity grows linearly for an exponentially long time.

Physicists know about the huge chasm between quantum physics and the theory of gravity. However, in recent decades, theoretical physics has provided some plausible conjecture to bridge this gap and to describe the behavior of complex quantum many-body systems, for example black holes and wormholes in the universe. Now, a theory group at Freie Universität Berlin and HZB, together with Harvard University, USA, has proven a mathematical conjecture about the behavior of complexity in such systems, increasing the viability of this bridge. The work is published in Nature Physics.

“We have found a surprisingly simple solution to an important problem in physics,” says Prof. Jens Eisert, a theoretical physicist at Freie Universität Berlin and HZB. “Our results provide a solid basis for understanding the physical properties of chaotic quantum systems, from black holes to complex many-body systems,” Eisert adds.

Could the Information Paradox Finally Be Resolved?

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

The information paradox may finally be resolved with the help of the holographic theory – but this time on a fractal scale.

Ever since Hawking predicted the thermal emission of black holes and their subsequent evaporation, the question arose as to where this information goes. In the context of the Copenhagen interpretation of quantum mechanics – which states that the information about a system is entirely encoded in its wave function – information is always conserved. Thus, any loss in information, like that predicted by Hawking and his evaporating black holes, would violate quantum theory. This problem is known as the information paradox.

To resolve this paradox, physicists have been actively looking for a mechanism to explain how the information of the infalling particles re-emerges in the outgoing radiation. To begin, they need to determine the entropy of the Hawking radiation.

Max Laughlin and his controversial theory: CERN sent us to a parallel universe?

Posted by in categories: cosmology, solar power, sustainability

The young man has made several statements that compromise the scientific community, but the most shocking is related to CERN and how it could have destroyed our universe.

Regarded as a genius child and listed as the “most intelligent young man in the world”, Max Laughlin surprised the world with his great intellectual abilities.

With only 13 years old he could develop from scratch its own device for energy access. A system that is capable of providing all the necessary energy without the need for oil, coal or solar energy.

Towards The Cybernetic Theory of Mind

Posted by in categories: cosmology, education, information science, quantum physics, robotics/AI

Local consciousness, or our phenomenal mind, is emergent, whereas non-local consciousness, or universal mind, is immanent. Material worlds come and go, but fundamental consciousness is ever-present, according to the Cybernetic Theory of Mind. From a new science of consciousness to simulation metaphysics, from evolutionary cybernetics to computational physics, from physics of time and information to quantum cosmology, this novel explanatory theory for a deeper understanding of reality is combined into one elegant theory of everything.

Information Could Be the 5th State of Matter, Proving We Live in a Simulation

Posted by in categories: cosmology, particle physics

If true, this idea could even help us understand all of the dark matter in our universe.


Trying to make sense of information is a universal daily experience. For physicist Melvin Vopson, this pursuit goes well beyond the mundane—he’s trying to prove that information has a physical presence. It’s a weighty task that could lead to new insights about how we can manage the future of information storage. It could also lead to a fundamental shift in how we think about the universe.

Vopson, who studies information theory at University of Portsmouth in the United Kingdom, wants to use an experiment to confirm that elementary particles have measurable mass. It would involve a matter-antimatter annihilation process that would shoot a beam of positrons at electrons in a piece of metal. Positrons and electrons are both subatomic particles, with the same mass and magnitude of charge. However, positrons are positively charged, and electrons are negatively charged.

New Clues to Earth’s Formation From Ancient Helium Leaking From the Planet’s Core

Posted by in category: cosmology

Vast stores of helium from the Big Bang lingering in the core suggest Earth formed inside a solar nebula.

Helium-3, a rare isotope of helium gas, is leaking out of Earth’s core, a new study reports. Because almost all helium-3 is from the Big Bang, the gas leak adds evidence that Earth formed inside a solar nebula, which has long been debated.

Helium-3 has been measured at Earth’s surface in relatively small quantities. But scientists did not know how much was leaking from the Earth’s core, as opposed to its middle layers, called the mantle.

Black holes found to exert a pressure on their environment

Posted by in categories: cosmology, physics

Physicists at the University of Sussex have discovered that black holes exert a pressure on their environment, in a scientific first.

In 1974 Stephen Hawking made the seminal discovery that emit thermal radiation. Previous to that, black holes were believed to be inert, the final stages of a dying heavy star.

The University of Sussex scientists have shown that they are in fact even more complex thermodynamic systems, with not only a temperature but also a .

One Lab’s Quest to Build Space-Time Out of Quantum Particles

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

The prospects for directly testing a theory of quantum gravity are poor, to put it mildly. To probe the ultra-tiny Planck scale, where quantum gravitational effects appear, you would need a particle accelerator as big as the Milky Way galaxy. Likewise, black holes hold singularities that are governed by quantum gravity, but no black holes are particularly close by — and even if they were, we could never hope to see what’s inside. Quantum gravity was also at work in the first moments of the Big Bang, but direct signals from that era are long gone, leaving us to decipher subtle clues that first appeared hundreds of thousands of years later.

But in a small lab just outside Palo Alto, the Stanford University professor Monika Schleier-Smith and her team are trying a different way to test quantum gravity, without black holes or galaxy-size particle accelerators. Physicists have been suggesting for over a decade that gravity — and even space-time itself — may emerge from a strange quantum connection called entanglement. Schleier-Smith and her collaborators are reverse-engineering the process. By engineering highly entangled quantum systems in a tabletop experiment, Schleier-Smith hopes to produce something that looks and acts like the warped space-time predicted by Albert Einstein’s theory of general relativity.

Star’s Mysterious Orbit Around Black Hole Proves Einstein Was Right— Again

Posted by in categories: cosmology, physics

Star’s mysterious orbit around black hole proves einstein was right all along—again.


The star, known as S2, has a 16-year elliptical orbit. It came near 20 billion kilometers of our black hole, Sagittarius A*, last year. If Isaac Newton’s traditional definition of gravity is correct, S2 should then continue on its previous orbit’s course through space. But it didn’t work.

Supermassive black holes put a brake on stellar births

Posted by in categories: cosmology, robotics/AI

Black holes with masses equivalent to millions of suns do put a brake on the birth of new stars, say astronomers. Using machine learning and three state-of-the-art simulations to back up results from a large sky survey, researchers from the University of Cambridge have resolved a 20-year long debate on the formation of stars.

Star formation in galaxies has long been a focal point of astronomy research. Decades of successful observations and theoretical modeling resulted in our good understanding of how gas collapses to form new stars both in and beyond our own Milky Way. However, thanks to all-sky observing programs like the Sloan Digital Sky Survey (SDSS), astronomers realized that not all galaxies in the local Universe are actively star-forming—there exists an abundant population of “quiescent” objects which form stars at significantly lower rates.
