Richard O. Calkins, author of Relativity Revisited, has released a new study for scientific peer review: A Report on How the Optical Laser Disproves the Special Theory of Relativity. This report overturns a cornerstone of generally accepted theory and restores the universe to Isaac Newton´s common sense laws. SAMMAMISH, WASHINGTON (PRWEB) April 25, 2013 Richard O. Calkins, author of Relativity Revisited, has released a new study for scientific peer review: A Report on How the Optical...

Speed Of Light May Not Be Fixed After All

John P. Millis, Ph.D. for redOrbit.com — Your Universe Online When we talk about the vacuum of space, we imagine a complete lack of matter — a cold void, dark, and absent of all energy. Over the last century, however, physicists have come to realize that the emptiness of space is anything by empty. On the macro scale, the vacuum of empty space may appear to lack matter and energy as we normally think of it. But when we look closely, and begin to examine the quantum...

Spacetime More Like A Smooth Whiskey Than A Foamy Brew

April Flowers for redOrbit.com - Your Universe Online According to new research led by Michigan Technological University, spacetime might be less like a foamy beer and more like a smooth Einsteinian whiskey. Robert Nemiroff and his team studied the tracings of three photons of differing wavelengths to reach this heady conclusion. NASA's Fermi Gamma-ray Space Telescope recorded these tracings in 2009. About 7 billion light years from Earth, a gamma ray outburst threw the photons from...

Spacetime Is Smooth, Not Foamy

April Flowers for redOrbit.com - Your Universe Online Scientists have long believed that spacetime is foamy, like a freshly pulled draft beer, but new information from an intergalactic photo finish shows it might just be as smooth as a single malt whiskey, instead. Robert Nemiroff, a physicist at Michigan Technological University, reached this conclusion after studying the tracings of three photons of differing wavelengths that had been recorded by NASA's Fermi Gamma-ray Space Telescope...

Spacetime -- In special relativity and general relativity, time and three-dimensional space are treated together as a single four-dimensional manifold called spacetime (alternatively, space-time; see below). A point in spacetime may be referred to as an event. Each event has four coordinates (t, x, y, z). Just as the x, y, z coordinates of a point depend on the axes one is using, so distances and time intervals, invariant in Newtonian physics, may depend on the reference frame of an...

Space -- The definition of space in physics is contentious. Various concepts used to try to define space have included: -- the structure defined by the set of "spatial relationships" between objects -- a manifold defined by a coordinate system where an object can be located. -- the entity that stops all objects in the universe from touching one another In classical physics, space is a three-dimensional Euclidean space where any position can be described using three...
