A Durham physicist explains gravitational waves. I can now almost understand it.
geology is so much simpler
Thursday this week saw a wonderful gift from a large international team of scientists and engineers to the rest of humankind. They reported the first detection of gravitational waves following their prediction by Albert Einstein a century before (in Einstein, A., Annalen der Physik 49, 769-822 (1916)] .
The discovery is the first-fruits of overwhelming human imagination, to conceive of such a thing as a wave that travels in the warp and weft of space and time itself, of the extraordinary talent, skill and care taken in building the exquisitely sensitive LIGO detectors, and of the deeply impressive patience, over decades, of researchers willing to devote fruitless decades to the long search in the hope that it will one day open our gravitational ‘ears’ to the sounds of the universe.
The astounding work deserves to be shared and enjoyed widely, and the scientists and science journalists have done an excellent job in…
