Eureka! Gravitational waves are finally detected!!
Laser Interferometer Gravitational-Wave Observatory(LIGO) scientists have directly detected presence of gravitational waves!
This is one stupendous achievement for astronomy and mankind which is first of its kind in history!
Gravitational waves are ripples caused in fabric of space-time (they are linked and appear like a sheet together) by some cosmic event caused by heavy objects like explosion of heavy stars or collision of black holes. Its same effect like if you drop a heavy object in water pond or dropping a ball on mattress, it will create outward waves simultaneously stretching and compressing matter (mattress or water body) while passing through it.
Einstein first proposed presence of gravitational waves 100 years back in his theory of general relativity, and today he ptoved himself correct yet again! This tells what kind of genius he was!
LIGO captured this landmark observation when gravitational waves passed through their detectors, created by collision of black holes 1.3 billion light years away and which sent ripples in space-time worth energy equivalent to mass of 3 suns!
They told that width of stretching of observation arm due to passing of wave was less than width of atomic nuclei! Implying if detectors arm is stretched some 41 trillion kilometers(distance between sun and its closest star), stretching would be equal to width of human hair! This is level of observations needed to pull off one of the most fascinating discovery of modern times! Bravo guys!!
This will open a new way to observe cosmic events which happen far away where we can not observe them directly, as gravitational waves do not get altered by anything in their path unlike light waves and hence carry pure and correct info about their creator!
I am quite excited as we might finally decode big bang some day as its ripples might be still playing around which we couldn't fathom until now!
Hopeful!!
