BETHLEHEM, Pa., June 9, 2014 /PRNewswire/ -- Particle Sciences, Inc.
According to conventional wisdom among physicists, gravity cannot become turbulent. However, new research has found that gravity can become turbulent, specifically around a black hole, because it behaves like a fluid.

When it comes to hurricanes, there are serious gender equality issues, according to new research which reveals that storms given feminine names tend to cause significantly more deaths than those with masculine ones.
A barometer is an instrument that measures atmospheric pressure. The barometer measures pressure exerted by the atmosphere using water, air, or mercury. Through measuring the pressure one can forecast short term weather changes. Evangelista Torricelli is credited with the invention of the barometer in 1643. However, Gasparo Berti unintentionally built a water barometer around the same time. Rene Descartes was also noted as describing an experiment to determine air pressure but there is no...
A Vortex (plural: vortices) is a spinning, often turbulent, mass of flowing fluid. Any spiral movement with a closed streamline is considered vortex flow. The speed and rate of rotation of a vortex is always greatest at the center, with progressively decreasing speed away from the center. The fluid pressure is lowest in the center of the vortex, and rises further from the center (Bernoulli's Principle). The core of a vortex is sometimes visible due to a plume of water vapor caused by...
Turbulence (or turbulent flow) is characterized by chaotic, random property changes. Turbulence occurs with low momentum diffusion (spreading of atmospheric properties), high momentum convection (vertical transference of atmospheric properties), and rapid variation of pressure and velocity in both space and time. A flow that is not turbulent is known as laminar flow. A vortex moving at low speeds will most likely cause laminar flow, and as speeds increase a transition is made to turbulent...
Comet -- A comet is a small body from the outer reaches of the solar system similar to an asteroid but composed of ice. Often described as "dirty snowballs," they are composed largely of carbon dioxide ice, methane ice, and water ice with a mixture of dust and small stony aggregates mixed in. Comets are thought to be small pieces of debris left over from the formation of the solar system, representing a sample of the original composition of the nebula that condensed to form the Sun and all...
