New Machine Learning Method Raises Questions on the Nature of Reality… Again

Article by Inés Urdaneta, Physicist, Resonance Science Foundation Research Scientist

Machine learning and artificial intelligence are increasingly taking the stage, with huge philosophical implications. We have been following this issue in our RSF science blog, first through the article Between the Holographic Approach and Data Science where we addressed the potential of trained artificial neural networks to replace our scientific models, and the possibility of reality being a numerical simulation was discussed. Somehow we had anticipated the work from Vitaly Vanchurin, from the University of Minnesota Duluth, proposing that we live in a neural network and affirming that only through neural networks we could find the theory of everything and grand unification theory. So, our second article entitled Is the universe a Neural network? addressed this later possibility.  

Today it was published in Phys.org an article entitled New machine learning method raises question...

More evidence of Collective Behavior at Cosmological Scale!

Article by Dr. Inés Urdaneta, Physicist, Resonance Science Foundation Research Scientist 

Just a couple of years ago, astronomers and astrophysicists were baffled by the observation of a synchronized behavior in galaxies, which can not be explained by their individual gravitational fields. Such was the case of a study lead by Joon Hyeop Lee, an astronomer at the Korea Astronomy and Space Science Institute, and published in The Astrophysical Journal in October 2018, reporting hundreds of galaxies rotating in sync with the motions of galaxies that were tens of millions of light years away.

Given the fact that from our known theories, in principle it would be impossible that galaxies separated by megaparsecs (millions of light years) could directly interact with each other, their interaction happens across distances that are too large to be explained by their gravitational force. It is then speculated that some unacknowledged force must be acting.

This discovery came...

Graphene Proves That Brownian Motion Can Be A Source of Energy!

Article by Ines Urdaneta, Physicist, Resonance Science Foundation Research Scientist

Graphene, one of the most important nanomaterials developed so far, continues to surprise the scientific community. This time, thanks to the extraordinary phenomena found by a group of physicists from the University of Arkansas. We are talking specifically about the capacity to use the thermal motion of atoms in graphene as a source of energy!

In this recent work, published in Physical Review E under the title Fluctuation-induced current from freestanding graphene, the team of researchers have successfully developed a circuit capable of capturing graphene's thermal motion and converting it into an electrical current. 

As it is said in this article: "The idea of harvesting energy from graphene is controversial because it refutes physicist Richard Feynman's well-known assertion that the thermal motion of atoms, known as Brownian motion, cannot do work. Thibado's team found that at room...

The Big Bang: A Big Bounce?

Article by Dr. Ines Urdaneta, Physicist and Research Scientist at Resonance Science Foundation

The most spread worldview on the origin of our Universe, is that of the big explosion, commonly known as the Big Bang (BB). We have asked ourselves what happens right after, at the first instants of the universe… the most accepted view among cosmologists is that of an exponential expansion, called the inflation theory.

The BB theory results from doing a backward-in-time evolution to the universes' expansion. If it is expanding as time moves forward, this implies the universe was smaller, denser and hotter in the distant past. The BB theory predicts that the early universe was much denser and extremely hot, about 273 million degrees above absolute zero, too hot for atoms to exist, only free electrons and hydrogen nuclei – protons and neutrons- where present.  After cooling during the expansion, these nuclei and electrons...

2020 Physics Nobel Prize to Black Holes!

Article by Dr. Inés Urdaneta, Resonance Science Foundation Research Scientist

Recently awarded the Nobel prize for the discovery that black hole formation is a robust prediction of the general theory of relativity, Sir Roger Penrose had earlier developed a theory known as “conformal cyclic cosmology“ (CCC) which posits that the universe iterates through infinite cycles, from one aeon to the next, such that the universe became uniform before rather than after the Big Bang. Each cycle starts out from a singularity before expanding and generating clumps of matter, which eventually gets sucked up by supermassive black holes, which over the very long term disappear by continuously emitting Hawking radiation. This process restores uniformity and sets the stage for the next Big Bang. In CCC, the future time-like infinity of each previous iteration being identified with the Big Bang singularity of the next. Penrose popularized this theory in his 2010 book Cycles of Time:...

Blue And Green Colors On Nature Are More Intense … Why?

By Ines Urdaneta, PhD in Physics and Researcher at Resonance Science Foundation.

Image: Evan Leeson/Bob Peterson/lowjumpingfrog. None of these animals contain a single trace of blue pigment.

Colors in nature come mainly from three sources: pigments, structural colors, and bioluminescence.

Have you noticed that some colors are more intense than others in nature?
Such is the case of blue and green colors, compared to reds and the rest. The main reason is that blue and green can be structural colors, while the remaining colors seem to not be part of the team.

Structural coloring is the result of microscopically fine structured surfaces that interfere with visible light, sometimes in combination with pigments. For example, peacock tail feathers are brown pigmented, but because of their microscopic structure, they also reflect blue, turquoise and green light. And they are often iridescent. Thus, structural coloring is a classic optical effect of interference and diffraction, rather than a...

Beyond Science Fiction! Extracting Energy from Black Holes

By Dr. Inés Urdaneta, Resonance Science Foundation Research Scientist

Image Credit: NASA/JPL-Caltech

In 1969, Roger Penrose proposed a method to extract rotational energy of a rotating black hole, and suggested that an advanced civilization could achieve it by lowering and then releasing a mass from a structure that is co-rotating with the black hole. The process would occur in the region just outside the event horizon, called the ergosphere, where frame-dragging is at its strongest, being able to tear apart an object; one part would enter the event horizon while the remaining one would be accelerated outwards with an additional impulse given by the rotational energy of the black hole. The excess energy calculated by Penrose was estimated to be 21 percent more than the incoming energy.


The process is brilliantly explained in this video: https://www.youtube.com/watch?time_continue=23&v=ES2VxhRAkUM&feature=emb_logo


Inspired by Penrose’s idea, Yakov Zel’dovich...

Quantum Computing via Electroluminescence

By Dr. Amira Val Baker, Resonance Science Foundation Astrophysicist

The first steps to achieving efficient electroluminescence necessary for quantum computing have just been made.

Quantum computers encode information in quantum bits otherwise known as qubits. These qubits can exist in the form of a photon or an electron, where the polarisation state of the photon or the spin state of the electron is taken as two bits of information. However, as opposed to classical bits, qubits can also exist in a superposition of states which allows the computer to process significantly more information and at a faster rate. This rate is limited by the transfer of information, which for an electron-spin qubit has so far proven difficult. Currently this has been achieved for distances up to millimetre scales, which although large from the qubit’s perspective, it is too small for practical applications.

To achieve the long-distance kilometre-scale transfer of quantum information encoded as...

The First Image of a Black Hole is Finally Here!

black holes science news Apr 29, 2020

 By Dr. Ines Urdaneta, Research Scientist at Resonance Science Foundation.
 
For some time now we have been following the Event Horizon Telescope initiative (EHT) aiming at the obtention of the first image of the EH of a Black Hole (BH) for Sagittarius A (Sag. A*), located at the center of our own galaxy, the milky way. Given the fact that Sag. A* nuclei is much less active that Messier 87 (M87*), the image reported first is that of M87*. Even though M87* is 2000 times farther away, it is 2000 times more massive. This compensates exactly the distance, with a higher nuclei activity allowing a better resolution and faster data analysis than Sag. A*.

So finally, the day has come! The moment couldn't be more exciting. First EHT results for the shadow of the BH, which is 55 million light years away from Earth, with a mass 6.5 billion times the mass of our Sun and located at the center of M87*, have been announced worldwide today, April 10th 2019, at the same time by different...

What’s Really Going on Inside a Neutron Star

science news Mar 14, 2020
by Dr. Amira Val Baker, Resonance Science Foundation Research Scientist

Scientists are finally getting closer to figuring out the puzzle of the structure of neutron stars and revealing the nature of their ultra-dense interiors.

In theories of stellar evolution, neutron stars are considered one of the end states of stars, along with white dwarfs and black holes. As a star evolves it will enter stages of expansion as hydrogen is fused into helium and so on through the periodic table of elements. Depending on the mass of the star, a limit will be reached whereby nuclear fusion can no longer take place and the star is no longer able to overcome the immense gravitational force which it has been holding back for all these years. As a result, the star implodes, ejecting its outer layers as a planetary nova or a supernova, leaving only a mere remnant of its former self behind – or so the story goes.

For massive stars, the implosion is so great that it crushes its stellar matter to...
