Einstein’s theory of special relativity brought us one of the most famous equations in science, E=mc2,
and showed that energy and mass are equivalent. In our modern,
high-tech world, operations involving digital information storage and
processing require huge amounts of energy. This gives way to the theory
behind the mass-energy-information equivalence principle, the idea that
because a bit of information is energy, it must have mass as well.
Landauer’s
principle links thermodynamics and digital information through logical
irreversibility. Experiments have proven the process of deleting a bit
of information dissipates heat energy, but after information is created,
it can be stored with no energy loss. Melvin Vopson proposes this
happens because once information is created, it acquires finite mass.
“This
idea is laboratory testable in principle,” said Vopson. He suggests
taking mass measurements of a digital data storage device when it has
full memory. If it has more mass than when the device’s memory is
cleared, then that would show the mass-energy-information equivalence is
correct. If the theory was to be confirmed, the implications would have an impact that could change the way we see the entire universe.
“For
over 60 years, we have been trying unsuccessfully to detect, isolate or
understand the mysterious dark matter,” said Vopson. “If information
indeed has mass, a digital informational universe would contain a lot of
it, and perhaps this missing dark matter could be information.”
Unfortunately,
taking the extremely small measurement needed to such precision may
currently be unachievable. Vopson proposes the next step to getting
answers could be developing a sensitive interferometer similar to LIGO
or an ultra-sensitive Kibble balance.

Initial studies of anti-ferroelectric materials at the University of Portsmouth and Iowa State University indicate
that these polar dielectrics can store digital information. The experimental
results are very encouraging. A
novel anti-ferroelectric random access memory chip (AFRAM) that will compete
with traditional ferroelectric random access memory (FRAM) to deliver twice the
memory storage capacity in the same volume, has been put forward. A US / EU patent on this technology has been granted: Anti-ferroelectric capacitor memory cell, Grant US-11355504-B2.
GENIES is a computer program developed to facilitate the study of genome
sequences in a comparative way using the information entropy. The
program can analyse genomes of any size by converting the genetic
information contained in a given genome into a numerical Information
Entropy Spectrum. The program allows fast detection of base point mutations from
the Information Entropy Spectra. Most importantly, the program could be
used to research and identify predictive algorithms of future genetic
mutations.
