Tim Scientists Find How to Order Random Chick of Particle Movement in the Cosmos
One
of the unsolved mysteries in contemporary science is how the structures
are highly organized to emerge from the random movement of particles. This
is true in many situations ranging from astrophysical objects which
stretches over millions of light years to the birth of life on Earth.The
surprising discovery that there is an electromagnetic field
self-organizing in the ionized gas (also known as plasma) will provide a
new way for scientists to explore how order emerges from chaos in the
cosmos. The findings were published online in the journal Nature Physics, 30 September."We
have created a model to explore how the electromagnetic field helps
regulate the ionized gas or plasma in astrophysical settings, such as
the plasma flows that arise from young stars," said lead author Nathan
Kugland, a post-doctoral researcher at the High Energy Density Science Group at Lawrence Livermore National Laboratory (LLNL). "Field-This
field help to shape current and possible role in supporting the
establishment of mutual gravity of the solar system, which could
ultimately lead to the formation of planets like Earth.""This
observation is totally unexpected, because the plasma moves so quickly
that should flow freely past each other," said Hye-Sook Park, team
leaders and staff physicist at LLNL. Park
added that "experiments of laser-plasma thrusters can learn the
microphysics of the interaction of plasma and the formation of
structures under controlled conditions."Studying
astrophysics to laboratory experiments to help answer questions about
astrophysical objects that are far beyond the reach of direct
measurement. This
study was conducted as part of an international collaboration,
Astrophysical Collisionless Shock Experiments with Lasers (ACSEL), led
by LLNL, Princeton University, Osaka University and the University of
Oxford.This work was performed at the OMEGA EP laser at Lawrence Livermore National Laboratory. Additional
support is provided by the LDRD program and the International
Collaboration for High Energy Density Science (ICHEDS), supported by
Core-to-Core Program of the Japan Society for the Promotion of Science. The
research leading to these surprising results received funding from the
European Research Council under the European Community's Seventh
Framework Programme.
