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

GRAVITATIONAL WAVES

G-wave Origin

• Some sources of G Waves are as follows:• Binary• Supernova• Rotating neutron stars• Inflation• Cosmic strings

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).

• Vacuum system• Length• Interferometers • Vibration isolation system • Mirrors are used • A splitter• It has a photodetector.

LIGO Observatories Description

• Suspension system • Series of tiny magnets

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.

• 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

Future Implementation

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

THANKING YOU
