The Laser Interferometer Gravitational-Wave Observatory (LIGO) set up to detect gravitational waves, the existence of which was predicted by Albert Einstein on the basis of his Theory of Relativity, is operated by:  Correct Answer Caltech and MIT 

The correct answer is Caltech and MIT .Key PointsHow do we know that gravitational waves exist?

  • In 2015, scientists detected gravitational waves for the very first time. They used a very sensitive instrument called LIGO (Laser Interferometer Gravitational-Wave Observatory). These first gravitational waves happened when two black holes crashed into one another. The collision happened 1.3 billion years ago. But, the ripples didn’t make it to Earth until 2015.

 Additional InformationWhat causes gravitational waves?

  • The most powerful gravitational waves are created when objects move at very high speeds. Some examples of events that could cause a gravitational wave are:
  • when a star explodes asymmetrically (called a supernova)
  • when two big stars orbit each other
  • when two black holes orbit each other and merge
  • But these types of objects that create gravitational waves are far away. And sometimes, these events only cause small, weak gravitational waves. The waves are then very weak by the time they reach Earth. This makes gravitational waves hard to detect.

 Important PointsHow are gravitational waves detected?

  • When a gravitational wave passes by Earth, it squeezes and stretches space.
  • LIGO can detect this squeezing and stretching.
  • Each LIGO observatory has two “arms” that are each more than 2 miles (4 kilometers) long.
  • A passing gravitational wave causes the length of the arms to change slightly. The observatory uses lasers, mirrors, and extremely sensitive instruments to detect these tiny changes

  • LIGO is made up of two observatories: one in Louisiana and one in Washington (above). Each observatory has two long “arms” that are each more than 2 miles (4 kilometers) long. 
  • It is made by Caltech/MIT/LIGO Lab

At an Electronic Data processing unit, five out of the eight program sets P,Q,R,S,T,U,V and W are to be operated daily. On any one day, except for the first day of a month, only three of the program sets must be the ones that were operated on the previous day.

India’s first Laser Interferometer Gravitational-Wave Observatory (LIGO) laboratory will be set up in which State?
Newton, Einstein, and Tesla working alone can do a piece of work in 20, 30, and 60 days respectively. All three of them start the work together, but after x days Newton leaves and then after y more days Einstein leaves and Tesla completes the remaining work. If Einstein had not left, Tesla and Einstein would have completed the remaining work in (y + 6) days after Newton had left. If both Newton and Einstein had stayed, the work would have been completed in (x + 6) days. What is the total number of days taken to complete the work?

The question below consist of a set of labelled sentences. Out of four options given, select the most logical order of the sentences which form a paragraph. When his parents moved to Italy in 1893, Einstein dropped out of school and renounced both his German citizenship and his Jewish faith. P. He applied to study at the Zurich Polytechnic, an advanced Swiss technical institute. Q. However, he failed the entrance examinations and was not accepted until spending a year of preparation at a Swiss secondary school. R. Between 1896 and 1900, he participated in a teachers' training program at the Zurich Polytechnic, where he met his lifelong friends Marcel Grossman and Michele Angelo Besso, as well as his first wife, Mileva Maric. S. Following the completion of his program in 1900, Einstein went on to work as a teacher and tutor in a series of posts in Germany and Switzerland. He finally settled in Bern, Switzerland, in 1902, where he received a job as a technical expert in a patent office. In Bern, Einstein married Mileva and the couple raised two sons together
