Scientists studying black hole mergers and gravitational waves have discovered possibilities of existence of stars and other celestial bodies that can mimic gravitational waves. … Background. This is useful for UPSC, SSC, State PCS, Bank PO examinations. Gravitational Waves What are gravitational waves? This makes it more important for the exam. The phenomenon detected was the collision of two black holes. Friday, 21 March 2014. Already have an account? Current Affairs for UPSC IAS Prelims. Almost every year, at least 10 - 15 questions are usually asked from this section. Movement of water caused by meteorological effects (winds and atmospheric pressure changes) are called surges (storm surge during cyclones). If we could detect the waves properly, then it would enable us to “see” the development of black holes and the development of stars. The group has also contributed to the astrophysical. Gravitational waves were proposed by Albert Einstein in his General Theory of Relativity over a century ago. Already have an account? Einstein was right! If the two bodies are black holes, space-time is shaken so violently that there is a veritable tsunami in the very fabric of space-time. Gravitational waves are expected to have frequencies greater than 10 to the power -16 and less than 10 to the power 4 hertz. This lecture provides an in depth explanation of Gravitational Waves. Gravitational waves are small ripples in space-time that are believed to travel across the universe at the speed of light. MCQs on Hepatitis and multi-drug resistance microbes were asked.

Gravitational waves are distortions or 'ripples' in the fabric of space-time caused by some of the most violent and energetic processes in the Universe. Posted by teamsupersimplified March 3, 2016 March 3, 2016 Posted in Current Affairs Tags: Bank PO, CGL, Current Affairs, Gravitational Waves, Gravitational Waves UPSC, Quiz, SSC, SSC CGL, … UPSC Quiz – 2020 : IASbaba’s Daily Current Affairs Quiz 1st Dec 2020; IASbaba’s TLP (Phase 2 – ENGLISH & हिंदी): UPSC Mains Answer Writing – General Studies Paper 2 Questions[1st DECEMBER,2020] – Day 44; Day 44 – Q 5. 4. Colliding black holes send ripples through spacetime that can be detected on Earth. There is no specified syllabus for General Science and Technology, but, from the previous years’ papers, the probable boundary of the syllabus of this section can be drawn.This section is divided into 6 subsections i.e. How do they get detected? This article will talk about LIGO India, an initiative for experimentation in gravitational waves. T he Laser Interferometer Gravitational-Wave Observatory (LIGO) - India is a planned advanced gravitational-wave observatory to be located in India as part of the worldwide network, whose concept proposal is now under active consideration in India and the USA. The wind blows the surface out of equilibrium causing the restoring force of gravity to force the surface back down, while the water’s buoyancy pushes it back up. There are different types of movements of ocean water under the influence of different physical characteristics like temperature, salinity, density, etc. They are often used to make very small measurements that are not achievable any other way. Gravitational Waves: In 1916, one of the greatest scientists in the history of mankind, Albert Einstein, had proposed a theory, which was a sister to his famous Theory of Relativity. The Government has given ‘in-principle’ approval for setting up Laser Interferometer Gravitational Wave Observatory (LIGO) in India. Stay abreast of recent events in Current Affairs, by visiting the linked article. Hence a special technique called matched filtering was adapted for gravitational wave data analysis which was developed at IUCAA (Inter-University Centre for Astronomy and Astrophysics), Pune. Gravitational waves are these ripples in the very geometry of space-time.

Einstein pictured these waves as ripples in the fabric of space-time produced by massive, accelerating bodies, such as black holes orbiting each other. They were predicted to exist by Albert Einstein in 1916 as a consequence of his General Theory of Relativity. Passing gravitational waves alternately squeeze and stretch objects by a tiny amount. They can be generated, for example, by supernovas, neutron star binaries spiralling around each other, and pairs of merging black holes. The discovery can pave the way for proving the general theory of relativity, so that we can look deeper and deeper into the universe. Not registered yet? The UPSC Previous Years’ Question Papers will be of immense help for candidates preparing for the exam. Strongest sources of gravitational waves are among enigmatic objects in our universe like black holes, supernova, neutron stars and Big Bang This discovery comes 100 years after Einstein first theorized gravitational waves. In other words, gravity waves are specific to planetary atmospheres and bodies of water. Since then, scientists have been evaluating their findings to make sure they were accurate. The gravitational waves that are detectible by LIGO will be caused by some of the most energetic events in the Universe—colliding black holes, exploding stars, and even the birth of the Universe itself.
