Brian Clegg: Gravity

A history of gravity, and a study of its importance and relevance to our lives, as well as its influence on other areas of science.  Physicists will tell you that four forces control the universe. Of these, gravity may the … Continue reading

Core Optics

A pair of polished Advanced LIGO end mirrors (ETM’s) Core optics are the 40-kg masses that form the heart of a LIGO detector. A core optic is manufactured from fused silica, polished to a few nanometers of smoothness and coated … Continue reading

Weber Bars Ring True?

Gravitational Radiation Gravitational waves have a polarization pattern that causes objects to expand in one direction, while contracting in the perpendicular direction. That is, they have spin two. This is because gravity waves are fluctuations in the tensorial metric of … Continue reading

Gravity is Talking, LISA will Listen

It seems by measure the Interferometer has come a long way. If one recognizes how gravitational waves are measured, you come to understand how they can have a affect on laser light. Bee and Stefan of Backreaction have gone to … Continue reading

Gran Sasso and the Pyramid

What good is a universe without somebody around to look at it?Robert Dicke This summer, CERN gave the starting signal for the long-distance neutrino race to Italy. The CNGS facility (CERN Neutrinos to Gran Sasso), embedded in the laboratory’s accelerator … Continue reading

What is Dark Matter/Energy?

When Chaos Goes Quantum? All events shown here (except KEK test detector) were generated by Monte-Carlo simulation program, written by Clark. The visualizing software which produced the detector images was written by Tomasz. While the sun was easily recognizable building … Continue reading

Now, here is a SuperNova for Real

The Crab Nebula from VLT Credit: FORS Team, 8.2-meter VLT, ESO Now the “ultimate proof” is to hold in our hands the matters defined by objects. This is the culmination of all dimensional perspectives, being “condensed to the moment” we … Continue reading
