New Delhi:
Are gravity and electromagnetism "two sides of the same coin"? An
Indian researcher says yes and advances the theory of the gravity
of planet Earth being linked to the electromagnetism generated
within its core. The research paper is up on a NASA site on
astrophysics and generating interest.
Ashwini Kumar Lal, an official with the Town and Country Planning
Organisation of India's urban development ministry, has in his
paper "On Planetary Electromagnetism and Gravity" said that the
gravitational pull on earth and similar planets like Mars, Venus
and Mercury is due to the generation of electromagnetism within
their interiors.
"There is an electrical dynamo working inside these planets. The
gravity on these planets is due to the electromagnetic force," Lal
told IANS.
Lal's paper was published in the June 2011 issue of the
peer-reviewed online American journal, Journal of Astronomy and
Astrophysics. It has also been put up on the Astrophysics Data
System (ADS), a digital library portal for researchers in
astronomy and physics, maintained by NASA and Harvard's
Smithsonian Center for Astrophysics.
"The outer core of the earth comprises iron and nickel, through
which electricity can pass. Since earth itself is rotating on its
axis, it creates an electric medium and the earth becomes like a
dynamo," he contends.
Lal also feels that his theory of gravity and electromagnetism
being two sides of the same coin "is a major statement in the laws
of physics" and could cause a "major upset in physics".
This is because the Standard Model of particle physics only
explains the interactions of three fundamental forces -
electromagnetic and the strong and the weak nuclear interaction,
but leaves out gravity, as it does not incorporate the theory of
general relativity.
Lal writes in his article: "Findings of the study undertaken
suggest that Earth's gravitational attraction may be attributed to
magnetic coupling experienced between Earth's electromagnetism and
all the earthly objects - electrically charged or uncharged. More
precisely, terrestrial gravity is deemed to be outcome of the
bound state of the planetary electromagnetism."
According to Professor T.V. Krishnan, a former scientist with the
Bhabha Atomic Research Centre (BARC), who is working with problems
in fundamental physics, "Dr Lal has sought to establish that
gravitation and electromagnetism are both sides of the same coin,
based on his studies of the Earth's magnetism. This has brought
into focus what is straight under our nose in particle physics,
but not noticed."
"The unit of magnetism depends on both mass and charge of the
particle (Bohr magneton). Electrostatic as well as
electro-magnetic forces depend on mass as well as charge.
"In fact every particle with energy, including the neutrino, has
mass given by Einstein's famous formula, E=mc˛ (energy equals mass
into speed of light squared). But what is true for a particle is
true for galaxies as well."
"Dr. Ashwini Kumar Lal seeks unity of concepts from the 'macro' to
the 'micro' and his conclusions that the forces are all related
deserves appreciation," says Prof Krishnan, who has authored a
book "Beyond the Barriers".
Lal has earlier authored three research papers in the fields of
astrophysics and physics that have been published in leading
European/American journals. His papers, including one on Origin of
Life, are also abstracted in the Astrophysics Data System digital
library.
