What are gravitational waves?
#Einstein predicted in 1916.
It took almost a century to realize that.
He was "way ahead of his time".
When a gravitational wave passes through objects will elongate and shrink alternatively.

But #GravitationalWaves are tiny so does the elongation and shrinking.
So scientists build an "L" shaped tunnel and sending laser from the middle point to both the edges and back continuously.
The length of the L shaped tunnel is 2.5 miles each side.

#gravity 2/n
The idea is when #gravitationalwaves pass through the L shape tunnel, one side will shrink and the other side will elongate bcoz they are diagonally opposite to each other.
The instrument is so sensitive that it can measure a change in length as small as 1/1000 of a proton. 3/n

1. Modest attempt to summarize PhD thesis in 10 tweets. It presented a theoretical, observational & astrophysical perspective on black holes 
2. Thesis had 3 parts (10 Ch.): #NumericalRelativity (Einstein on supercomputers), blackhole search in #LIGO & #GravitationalWave universe👇🏻
3. #NumericalRelativity simulation gives us EXACT spacetime physics when 2 black holes collide. It takes 50k hours on fastest supercomputers
