The Big Picture

Posted by in categories: cosmology, neuroscience, quantum physics, virtual reality

Interesting write up some fiction and some non-fiction brought together on a common theory about Quantum. I do have a huge curiosity around the work going on the parallel states research and the job postings by some companies for psychics. Wouldn’t it be funny that if all these folks who thought they saw something like a spirit really did due to Quantum parallel states? What if Musk and others who believe we’re living in VR was actually true and was because of the same thing with the psychics? Who knows; but does make one think for a minute about what if.


The theoretical physicist has written a bold book that deals with the biggest questions, taking in quantum theory and free will along the way.

Black holes on an electronic chip

Posted by in categories: computing, cosmology, nanotechnology, quantum physics

Watch out for the black holes in those QC chips.


Eindhoven professor Rembert Duine has proposed a way to simulate black holes on an electronic chip. This makes it possible to study fundamental aspects of black holes in a laboratory on earth. Additionally, the underlying research may be useful for quantum technologies. Duine (also working at Utrecht University) and colleagues from Chile published their results today in Physical Review Letters.

“Right now, it’s purely theoretical,” says Duine, “but all the ingredients already exist. This could be happening in a lab one or two years from now.” One possibility is in the group of Physics of Nanostructures in the Department of Applied Physics. According to Duine, in these labs experiments are being done that are necessary to create this type of black holes.

These powerful blazars are the most distant ever seen

Posted by in category: cosmology

Monster black holes shooting jets of gamma-ray radiation right at us have been spotted farther away than ever before, dating back to when the universe was nearly one-tenth its current age.

The five distant objects, called gamma-ray blazars, deepen the mystery of how black holes so large could have formed so early in the universe’s history.

Roopesh Ojha, an astronomer at NASA’s Goddard Space Flight Center in Maryland, presented the new results during a press conference today (Jan. 30) at the American Physical Society meeting in Washington, D.C. The results will also be published in The Astrophysical Journal Supplement. [Found: Gamma-Ray Blazars Powered by ‘Supersized’ Black Holes (Video)].

Physicists Simulate Sending Particles of Light Into the Past, Strengthening the Case that Time Travel Is Possible

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

Awesome! More news on the time crystals.


The source of time travel speculation lies in the fact that our best physical theories seem to contain no prohibitions on traveling backward through time. The feat should be possible based on Einstein’s theory of general relativity, which describes gravity as the warping of spacetime by energy and matter. An extremely powerful gravitational field, such as that produced by a spinning black hole, could in principle profoundly warp the fabric of existence so that spacetime bends back on itself. This would create a “closed timelike curve,” or CTC, a loop that could be traversed to travel back in time.

The Physics of Everything, with Michio Kaku

Posted by in categories: cosmology, information science, physics

What if we could find one single equation that explains every force in the universe? Professor Michio Kaku explores how physics could potentially shrink the science of the big bang into an equation as small as E=mc².

Plasma tidal wave may tell us if black holes destroy information

Posted by in categories: cosmology, physics

Physicists have long puzzled over whether black holes destroy information or conserve it – now a proposed lab experiment could use a plasma wave to find out.

Violations of energy conservation in the early universe may explain dark energy

Posted by in categories: cosmology, quantum physics

(Phys.org)—Physicists have proposed that violations of energy conservation in the early universe, as predicted by certain modified theories of quantum mechanics and quantum gravity, may explain the cosmological constant problem, which is sometimes referred to as “the worst theoretical prediction in the history of physics.”

The physicists, Thibaut Josset and Alejandro Perez at the University of Aix-Marseille, France, and Daniel Sudarsky at the National Autonomous University of Mexico, have published a paper on their proposal in a recent issue Physical Review Letters.

“The main achievement of the work was the unexpected relation between two apparently very distinct issues, namely the accelerated expansion of the universe and microscopic physics,” Josset told Phys.org. “This offers a fresh look at the cosmological constant problem, which is still far from being solved.”

“The Black Hole That Gave Birth to the Universe” — (Weekend “Galaxy” Stream)

Posted by in categories: cosmology, physics

The big bang poses a big question: if it was indeed the cataclysm that blasted our universe into existence 13.7 billion years ago, what sparked it? Three researchers at the Perimeter Institute for Theoretical Physics and the University of Waterloo propose that the big bang could be the three-dimensional “mirage” of a collapsing star in a universe profoundly different than our own.

Astronomers Have Discovered an Insane Galactic Particle Accelerator, Fuelled by a Black Hole

Posted by in categories: cosmology, particle physics

An international team of astronomers have discovered a ‘cosmic one-two punch’ in the night sky that has never been seen before. In one image, the team managed to spot a supermassive black hole and two gigantic galaxy clusters colliding at the same time.

Matter ejected from the black hole gets caught up inside the violent galactic collisions, turning this dynamic duo into one hell of an enormous cosmic particle accelerator.

“We have seen each of these spectacular phenomena separately in many places,” said team leader Reinout van Weeren, from the Harvard-Smithsonian Centre for Astrophysics.
