Los científicos estadounidenses Rainer Weiss, Barry C. Barish y Kip S. Thorne ganaron hoy el Premio Nobel de Física 2017 por su “decisiva contribución al detector LIGO y la observación de las ondas gravitacionales”, según anunció la Real Academia Sueca de las Ciencias.

Los tres galardonados contribuyeron “con su entusiasmo y determinación” de forma “inestimable” para poner en marcha el Observatorio de Ondas Gravitacionales por Interferometría Láser (LIGO), la iniciativa que detectó por primera vez esas ondas.

Este proyecto en el que colaboran miles de científicos de alrededor de veinte países, fue el que detectó por primera vez, el 14 de septiembre de 2015, este fenómeno cósmico que Albert Einstein había predicho un siglo antes en su Teoría General de la Relatividad.

El jurado explicó que esa vibración, que llegó a la Tierra de forma “extremadamente débil”, provenía de la colisión de dos agujeros negros, sucedida hace 1.300 millones de años.

Esta medición “es ya una prometedora revolución en la astrofísica”, argumentó el comunicado de prensa de la academia.

La dotación del premio es de 9 millones de coronas suecas (1,1 millones de dólares), después de que este año la Fundación aumentara el monto de las distinciones Nobel por primera vez en cinco años. Weiss recibirá la mitad del premio en metálico de este Nobel y sus dos colegas compartirán el resto.

Weiss, Thorne y Barsih trabajan en la Colaboración Científica LIGO y VIRGO, que une a los detectores del LIGO localizados en Livingston (Louisiana) y Hanford (Washington) y el detector franco-italiano VIRGO, localizado cerca de Pisa (Italia)

Rainer Weiss nació en Berlín en 1932. Escapando de la Alemania nazi, su familia se trasladó a Praga, a fines de ese año, y luego a Estados Unidos en 1938. Actualmente, Weiss ejerce en el Instituto de Tecnológico de Massachusetts (MIT); mientras que Barry Barish, nacido en Omaha (Estados Unidos) en 1936, trabaja en el Instituto de Tecnología de California (Caltech) junto a su colega Kip S. Thorpe, nacido en Logan (Estados Unidos) en 1949.

La semana Nobel arrancó ayer con la concesión del premio de Medicina a los estadounidenses Jeffrey C. Hall, Michael Rosbash y Michael W. Young por sus investigaciones sobre el “reloj biológico”. Mañana se conocerá al ganador o ganadores del Nobel de Química; el jueves, el de Literatura; el viernes, el de la Paz; y el lunes siguiente, el de Economía.

A vacuum cleaner, also referred to as a vacuum or a electrical hoover, is an extremely popular and
effective machine that induces intense suction to pull debris out from drapery, upholstery, carpeted and
other surfaces. It's usually operated electrically. This sort of cleaning equipment can clean the whole house with no restriction; it will clean the carpets, carpeting, furniture and just about any
surface inside your house. It can do more than 1 thing at one
time, that's another feature of the great invention. This
type of cleaner has many advantages over the traditional forms but there
are also some disadvantages of the cleaning appliance.
