I am working on a new paper about black holes, here is a teaser of what is coming soon. Black Holes are perhaps the perfect example of extreme environments in the universe, with massive gravity in the form of profound spacetime curvature and seemingly impossible physics at their singularity. In modern astrophysics and cosmology, it […]

This is a contemporary review of the involvement of Mileva Marić, Albert Einstein’s first wife, in his theoretical work between the period of 1900 to 1905. Separate biographies are outlined for both Mileva and Albert, prior to their attendance at Zürich Polytechnic in 1896. Then a combined journal is described, detailing significant events. In additional

Christof Wetterich, a theoretical physicist at the University of Heidelberg in Germany, posted a paper on the arXiv preprint server, that offers a different cosmology in which the Universe is not expanding but the mass of everything has been increasing over time. Although the paper has yet to be peer-reviewed, none of the experts contacted

Sep 13, 2011 Could the Sun test alternative theories of gravity? Alternatives to Einstein’s general theory of relativity can be investigated by studying the Sun. That is the claim of a group of physicists in Portugal who have found that a variation of a theory put forward nearly a century ago by Arthur Eddington is

Aug 23, 2011 Who discovered that E = mc2? It’s not as easy a question as you might think. Scientists ranging from James Clerk Maxwell and Max von Laue to a string of now-obscure early 20th-century physicists have been proposed as the true discovers of the mass–energy equivalence now popularly credited to Einstein’s theory of

NEW METHOD OF MAPPING THE UNIVERSE USING QUASARS -BOSS. The biggest 3-D map of the distant universe ever made, using light from 14,000 quasars – supermassive black holes at the centers of galaxies billions of light years away – has been constructed by scientists with the third Sloan Digital Sky Survey (SDSS-III). See the Phyorg

Jan 5, 2005 The last 30 years of his life were spent on a fruitless search for a unified field theory, but as John Ellis explains, Einstein put this “holy grail” of modern physics on the theoretical map. The definitive scientific biography of Einstein, Subtle is the Lord…, which was written by Abraham Pais in

Jan 5, 2005 Gravitational physics has become a truly experimental science as tests of the special and general theories of relativity reach new levels of precision When I was a first-term graduate student in the late 1960s, it was said that the field of general relativity was “a theorist’s paradise and an experimentalist’s purgatory”. There
