Does Information Carry Mass?

If information carries mass, could it be the dark matter physicists are craving?

The existence of dark energy and dark matter was inferred in order to correctly predict the expansion of the universe and the rotational velocity of galaxies. In this view, dark energy could be the source of the centrifugal force expanding the universe (it is what accounts for the Hubble constant in the leading theories), while dark matter could be the centripetal force (an additional gravity source) necessary to stabilize galaxies and clusters of galaxies, since there isn’t enough ordinary mass to keep them together. Among other hypotheses, dark energy and dark matter are believed to be related to the vacuum fluctuations, and huge efforts have been devoted to detecting it. The fact that no evidence has yet been found calls for a change of perspective that could be due to information theory.

How could we measure the mass of information?
Dr. Melvin Vopson, of the University of Portsmouth, has a hypothesis he calls the mass-energy-information equivalence. It extends the already existing information-energy equivalence by proposing information has mass. Initial works on Shannon’s classical information theory, its applications to quantum mechanics by Dr. Wheeler, and Landauer’s principle predicting that erasing one bit of information would release a tiny amount of heat, connect information to energy. Therefore, through Einstein’s equivalence between mass and energy, information – once created – has mass. The figure below depicts the extended equivalence principle.

In order to find the mass of digital information, one would start with an empty data storage device, measuring its total mass with a highly sensitive device. Once the information is recorded in the device, its mass is measured again. The next step is to erase one file and measure again. The limiting step is the fact that such an ultra-sensitive device doesn’t exist yet. In his paper published in the journal AIP Advances, Vopson proposes that this device could be in the form of an interferometer similar to LIGO, or a weighing machine like a Kibble balance. In the same paper, Vopson describes the mathematical basis for the mechanism and physics by which information acquires mass, and formulates this powerful principle, proposing a possible experiment to test it.

In regard to dark matter, Vopson says that his estimate of the ‘information bit content’ of the universe is very close to the number of bits of information that the visible universe would contain to make up all the missing dark matter, as estimated by M.P. Gough and published in 2008,.

This idea is synchronistic with the recent discovery that sound carries mass (, i.e., phonons are massive.

Vopson is applying for a grant in order to design and build the measurement device and perform the experiments. We are so looking forward to his results!

RSF in perspective

Both dark matter and dark energy have been inferred as a consequence of neglecting spin in the structure of space-time. In the frame of the Generalized Holographic approach, spin is the natural source of centrifugal and centripetal force that emerges from the gradient density across scales, just as a hurricane emerges due to pressure and temperature gradients. The vacuum energy of empty space – the classical or cosmological vacuum – has been estimated to be 10−9 joules per cubic meter. However, vacuum energy density at quantum scale is 10113joules per cubic meter. Such a discrepancy of 122 orders of magnitude difference in vacuum densities between micro and cosmological scales is known as the vacuum catastrophe. This extremely large density gradient in the Planck field originates spin at all scales.

Additionally, the holographic model explains mass as an emergent property of an information transfer potential between the information-energy stored in a confined volume and the information-energy in the surface or boundary of that volume, with respect to the size or volume of a bit of information. Each bit of information-energy voxelating the surface and volume is spinning at an extremely fast speed. Space is composed of these voxels, named Planck Spherical Units (PSU), which are a quanta of action. The expressed or unfolded portion of the whole information is what we call mass.

Light Photographed As A Wave And A Particle For The First Time

Scientists have long known that light can behave as both a particle and a wave—Einstein first predicted it in 1909. But no experiment has been able to show light in both states simultaneously. Now, researchers at the École Polytechnique Fédérale de Lausanne in Switzerland have taken the first ever photograph of light as both a wave and a particle. The key was a new experimental technique that uses electrons to capture the light’s movement. The work was published today in the journal Nature Communications.

To get this snapshot, the researchers shot laser pulses at a nanowire. The wavelengths of light moved in two different directions along the metal. When the waves ran into each other, they look liked a wave standing still, which is effectively a particle.

In order to see how the waves were moving, the researchers shot a beam of electrons at the nanowire, like dropping dye in a river to see the currents. The particles in the light wave changed the speed at which the electrons moved. That enabled the researchers to capture an image just as the waves met.

“This experiment demonstrates that, for the first time ever, we can film quantum mechanics – and its paradoxical nature – directly,” said Fabrizio Carbone, one of the authors of the study, in a press release. Carbone hopes that a better understanding of how light functions can jumpstart the field of quantum computing.

The ‘X17’ particle: Scientists may have discovered the fifth force of nature

A new paper suggests that the mysterious X17 subatomic particle is indicative of a fifth force of nature.

Physicists have long known of four fundamental forces of nature: gravity, electromagnetism, the strong nuclear force, and the weak nuclear force. 

Now, they might have evidence of a fifth force. 

The discovery of a fifth force of nature could help explain the mystery of dark matter, which is proposed to make up around 85 percent of the universe’s mass. It could also pave the way for a unified fifth force theory, one that joins together electromagnetic, strong and weak nuclear forces as «manifestations of one grander, more fundamental force,» as theoretical physicist Jonathan Feng put it in 2016.

The new findings build upon a study published in 2016 that offered the first hint of a fifth force.

Quantum Leaps, Long Assumed to Be Instantaneous, Take Time






When quantum mechanics was first developed a century ago as a theory for understanding the atomic-scale world, one of its key concepts was so radical, bold and counter-intuitive that it passed into popular language: the “quantum leap.” Purists might object that the common habit of applying this term to a big change misses the point that jumps between two quantum states are typically tiny, which is precisely why they weren’t noticed sooner. But the real point is that they’re sudden. So sudden, in fact, that many of the pioneers of quantum mechanics assumed they were instantaneous.

Quantum Teleportation Enters the Real World







Two separate teams of scientists have taken quantum teleportation from the lab into the real world. Researchers working in Calgary, Canada and Hefei, China, used existing fiber optics networks to transmit small units of information across cities via quantum entanglement — Einstein’s «spooky action at a distance.»Stepping Outside the LabAccording to quantum mechanics, some objects, like photons or electrons, can be entangled.
