This document provides an introduction to gravitational waves, including a brief history of their prediction and discovery. It describes their origin and how the Laser Interferometer Gravitational-Wave Observatory (LIGO) detects them using highly sensitive laser interferometers located in Hanford, Washington and Livingston, Louisiana. The document notes that detecting gravitational waves could provide insights into the formation of black holes, test theories like the Big Bang theory, and may one day enable time travel.

2. INTRODUCTION
 DESCRIPTION
• WHAT IS G-WAVES ?
• SOURCE OF PRODUCTION.
 HISTORY
• DATE OF PREDICTION AND DISCOVERY.

3. G-wave Origin

4. LIGO (Laser Interferometer Gravitational-Wave observatory)
LOCATION:-
Two LIGO observatory are present. They are situated in
1. Hanford (LIGO Hanford observatory) .
2. Livingston (LIGO Livingston observatory).

5. LIGO Observatories Description

6. • Suspension system
• Series of tiny magnets

7. Operation
• The main goal is to approach very limit down to a scale so small that
quantum laws turn the straight lines of a ruler into a tangle of fussy
impression.

8. • The laser goes through the beam splitter
• When a gravitational wave comes, it distorts the space and time
• So now the pick and the valleys of the recombined light doesn’t
remain aligned

9. • BIRTH OF BLACK HOLE
• BIG BANG THEORY
• THEORY OF EVERYTHING
• TIME TRAVEL

10. THANKING YOU
