Einstein's Biggest Blunder? Dark Energy May Be Consistent With Cosmological Constant
November 27, 2007 — Einstein's self-proclaimed "biggest blunder" -- his postulation of a cosmological constant (a force that opposes gravity and keeps the universe from collapsing) -- may not be such a blunder after ... > full story -
Warp Speed Improves Calculations a Million Times
November 12, 2007 — Thanks to Einstein, physicists know that the world looks different depending on how fast you're moving. A new analysis shows that it a lot prettier (mathematically speaking) if you're moving at just ... > full story -
Physicist Defends Einstein's Theory And 'Speed Of Gravity' Measurement
October 3, 2007 — Scientists have attempted to disprove Albert Einstein's theory of general relativity for the better part of a century. After testing and confirming Einstein's prediction in 2002 that gravity moves at ... > full story -
What Is Dark Energy? 'Beyond Einstein' Program Aims To Investigate
September 6, 2007 — NASA and the US Department of Energy should pursue the Joint Dark Energy Mission as the first mission in the "Beyond Einstein" program, according to a new report from the National Research Council. ... > full story -
Could Physicists Make A Time Machine? It All Depends On Curving Space-Time
August 22, 2007 — Researchers have developed a theoretical model of a time machine that, in the distant future, could possibly enable future generations to travel into the past. The main question is: if, according to ... > full story -
Unravelling The Random Fluctuations Of Nothing
August 5, 2007 — The dream of theoretical physics is to unite behind a common theory that explains everything, but that goal has remained highly elusive. String theory emerged 40 years ago as one of the most ... > full story -
Bending Polymers Provides Spontaneous Way To Duplicate Beauty Of Nature
July 22, 2007 — There are many objects in nature, such as flowers, that are "pre-programmed" to develop into delicate, beautiful and intrically shaped forms. But can this pre-determined process be duplicated by man ... > full story -
Old Math Model Aids Search For Gravitational Waves
June 22, 2007 — A new way of looking at a previously abandoned mathematical model might help astronomers study and accurately identify an exotic clan of gravitational ... > full story -
Physicist Says Testing Technique For Gravitomagnetic Field Is Ineffective
June 1, 2007 — A major focus on the study of Einstein's theory of general relativity has been on confirming the existence of the gravitomagnetic field, as well as gravitational waves. A physicist recently argued in ... > full story -
Cloaking Device? Invisible Technology One Step Closer
May 3, 2007 — A unique computer model designed by a mathematician has shown that it is possible to make objects, such as airplanes and submarines, appear invisible at close ... > full story
