2017 Nobel Prize Currently Awarded in Physics is for?

  • Far Observation of Gravitational Waves
  • Far Observation of Gravitational Weight
  • First Observation of Gravitational Waves
  • Far Objectivity of Gravitational Waves
Correct Answer: C. First Observation of Gravitational Waves

Detailed Explanation

The correct answer is First Observation of Gravitational Waves.


The Nobel Prize in Physics 2017 was awarded to three American physicists: Rainer Weiss, Barry C. Barish, and Kip S. Thorne. They received the prize for their decisive contributions to the LIGO detector and the first-ever direct observation of gravitational waves.


What are Gravitational Waves?


Gravitational waves are "ripples" in the fabric of space-time. They were first predicted by Albert Einstein in 1916 as part of his General Theory of Relativity. Einstein believed they would be so weak that they might never be detected.


The Breakthrough Discovery:


On September 14, 2015, the LIGO (Laser Interferometer Gravitational-Wave Observatory) detectors in the United States recorded a signal for the first time.



  • The Source: The waves came from a collision between two massive black holes that happened 1.3 billion years ago.

  • The Significance: This discovery opened a new window into the universe, allowing scientists to "hear" cosmic events that do not emit light, such as black hole mergers.


Comparison of the Options:




  • Far Observation... / Far Objectivity...: These are distractor terms. The word "Far" is not part of the scientific description of the award.

  • Gravitational Weight: This is a scientifically incorrect term; "weight" refers to the force of gravity on an object, whereas "waves" refer to the radiation of gravitational energy.

  • First Observation of Gravitational Waves: The correct answer. It highlights that this was the initial direct physical confirmation of a century-old theory.
