EINSTEIN WAS RIGHT
ALL THIS TIME
A hundred years ago Einstein has predicted that the
gravitational force is in the form of waves in his general
theory of relativity and scientists have confronted and
confirmed these ripples ultimately.
An article from Nature “Einstein’s gravitational waves
found at last” states that the physicists with the help
of LIGO (Laser Interferometer Gravitational-Wave
Observatory) have revealed the awaited confirmation
on February 11 indicating that their twin detectors
have caught the ‘gravitational ringing’ caused by a
collision of two black holes 1.3 billion light-years away
from Earth. This oscillation showed up at a frequency
of 35 Hz and sped up to 250 Hz before disappearing
after 0.25 seconds according to the LIGO’s automatic
systems.
Einstein may have predicted the gravitational waves
but proving it was not easy. It took 8 decades to create
the technology that can spot the waves at ridiculous
distances and took 2 decades to spot the collision of
two massive black holes 1.3 billion years away from us.
This makes the confirmation unbelievably valuable.
The science world has gone crazy since this discovery.
“Ladies and gentlemen, we have detected gravitational
waves.” Said David Reitze, the executive director of
LIGO at a Washington DC press conference.

THE CLAPPER 2015 - 2016
“It is by far the most powerful explosion humans
have ever detected except for the big bang.” Says
Kip Thorne, a gravitational theorist at Caltech.
Undoubtedly this discovery of gravitational waves has
created a sensation but the questions await; “How is it
discovered?” and “What will be the outcome?”
