The two physics stories that dominated the news in 2011 were questions rather than solid scientific results, namely "Do neutrinos travel faster than light?" and "Has the Higgs boson been found?". However, there have also been some fantastic bona fide research discoveries over the last 12 months, which made it difficult to decide on the Physics World 2011 Breakthrough of the Year. But after much debate among the Physics World editorial team, this year's honour goes to Aephraim Steinberg and colleagues from the University of Toronto in Canada for their experimental work on the fundamentals of quantum mechanics. Using an emerging technique called "weak measurement", the team is the first to track the average paths of single photons passing through a Young's double-slit experiment – something that Steinberg says physicists had been "brainwashed" into thinking is impossible.

General relativity or the general theory of relativity is the geometric theory of gravitation published by Albert Einstein in 1916. [ 1 ] It is the current description of gravitation in modern physics . General relativity generalises special relativity and Newton's law of universal gravitation , providing a unified description of gravity as a geometric property of space and time , or spacetime .

Alan Kostelecky: Background information on Lorentz/CPT violation We have shown in our publications that arbitrary Lorentz and CPT violations are quantitatively described by a theory called the Standard-Model Extension, which is a modification of the usual Standard Model of particle physics and Einstein's theory of gravity, General Relativity. The Indiana University Center for Spacetime Symmetries (IUCSS) Our basic premise is that minuscule apparent violations of Lorentz and CPT invariance might be observable in nature.

The Mystery of Empty Space , 9.4 out of 10 based on 39 ratings Get ready to re-think your ideas of reality. Join UCSD physicist Kim Griest as he takes you on a fascinating excursion, addressing some of the massive efforts and tantalizing bits of evidence which suggest that what goes on in empty space determines the properties of the three-dimensional existence we know and love, and discusses how that reality may be but the wiggling of strings from other dimensions.

Gravitational microlensing - Wikipedia, the free encyclopedia Microlensing is based on the gravitational lens effect. A massive object (the lens) will bend the light of a bright background object (the source).

Spacetime around a massive object (such as a galaxy cluster or a black hole ) is curved, and as a result light rays from a background source (such as a galaxy ) propagating through spacetime are bent. The lensing effect can magnify and distort the image of the background source. Gravitational lens - Wikipedia, the free encyclopedia

10 Strange Things About The Universe One of the longest outstanding mysteries in physics is how gravity is related to the other fundamental forces, such as electromagnetism. One theory, first proposed in 1919, showed that if an extra dimension is added to the universe, gravity still exists in the first four dimensions (three space dimensions and time), but the way this four dimensional space curves over the extra fifth dimension, naturally produces the other fundamental forces. However, we cannot see or detect this fifth dimension, so it was proposed that the extra dimension was curled up, and hence became invisible to us.
