Gravitational Wave Astronomy is a fascinating discovery made a few years ago that changed the notions of modern physics. This presentation won the 3rd Prize in the SPIE student chapter's Oral Presetation in my college.

GRAVITATIONAL WAVE ASTRONOMY A NEW GATEWAY TO THE UNIVERSE A Presentation by
What does this actually mean?
Gravity! Waves! Newton Sir! Yup slight stress on your memories? The Water Tub? In your backyard? Astronomy Time to get back to the balcony! Unravel the Mystery
Newton’s Universal Law of Gravity It states that a particle attracts every other particle in the universe using a force, but how actually the force got implemented? Why is the moon revolving around the Earth instead of striking it? Who asked the moon to do so? Kepler’s Laws : Check! What about mercury changing its orbit?
Shifting in the Mercury’s orbit
Call him in! Einstein decided to answer the questions, and he inferred that Newton’s Laws are valid only till inertial frame of reference is used. The Theory of relativity.
The Space-TimeMesh “Spacetime tells matter how to move, And matter tells spacetime how to curve” Einstein Proposed
Space Time – The Trampoline model
Gravitational Waves-Illustration
Gravitational Waves? What is its use to us? Existence of Black Holes Its distance and Characteristics Dark Matter’s Characteristics, its mass and complexities Making The universe a Laboratory! (we cannot replicate stars here :D)
Arewe in? Dothese waves exist? How canwe be so sure? The Laser Interferometer
The Laser Interferometer Gravitational Wave Observatory(LIGO) HANFORD ,WASHINGTON
Demonstration of The working of The LIGO
September 2016. The D-day. 0.2 seconds = Centuries of Knowledge Gravitational Waves formed by Binary Black holes Waveforms matched predictions. And A new window opened.
Why bother? Its up in the space! The LIGO required Technological advancements, a boon for our future. • Seismic Isolation --- feed 1 billionth the energy of normal ground vibration into our instruments . • we have required and received the most precisely polished mirrors. • we have developed new suspension and control systems to stabilize our optics.
Why bother at all? We are a very small part of the Universe, but we are a part of it nonetheless. Understand Universe= Understand Yourselves.
