Big Steps in Gravitational Wave Detection

Today, May 19, the LIGO Scientific Collaboration (“LSC”) dedicates its second-generation gravitational-wave detectors (“aLIGO”) in a ceremony at the Hanford detector site. Researchers at the… 310 more words

Relativity and relatives

[ I assembled two new bookshelves, so I have room for my science books for the first time in a long while. In honor of the occasion, I’m writing a few personal essays inspired by books. 1,539 more words

SHARING 24 WONDROUS SPECTACULAR STAR FORMATIONS!!!

If after viewing these spectacular pictures of the universe you would have to be a little insane to still think that the universe obeys the simpleton law of general relativity!!!!!! 199 more words

Common Sense

Read Einstein

Devoted readers of this blog (assuming there are any) know that I’ve been studying relativity for some time — for why see https://luysii.wordpress.com/2011/12/31/some-new-years-resolutions/.

Probably some of you have looked at writings about relativity, and have seen equations containing terms like ( 1 – v^2/c^2)^1/2. 560 more words

GFT Condensates and Cosmology

This week I have been studying some papers and a seminar by Lorenzo Sindoni and Daniele Oriti on Spacetime as a Bose-Einstein Condensate. I have also been reading a great book ‘The Universe in a Helium Droplet’ by Volovik and a really good PhD Thesis, ‘Appearing Out of Nowhere: The Emergence of Spacetime in… 618 more words

The gravitational effect of an intense laser

METRIC INDUCED BY AN INTENSE LASER FIELD

The gravitational coupling between laser beams was examined by Scully via the Einstein-Maxwell equations, and the amplitude and phase variations of a probe pulse due to a high intensity laser pulse were obtained. 156 more words
