A few year back –
in 2002 to be precise I started getting interested with the work of Stephen
Hawkins and black holes – (thanks to Tom and Nancy Stuehler from Baltimore who gave me priceless material on this). I
have listened to his lectures and even read some of his books. It is a very
interesting topic. It is said that fact is sometimes stranger than fiction, and
nowhere is this more true than in the case of black holes. Black holes are
stranger than anything dreamt up by science fiction writers, but they are
firmly matters of science fact.
Yesterday was a
very interesting moments for those who have always gazed up with quest to probe
– what is up – or out there? Einstein theory of Relativity was finally and
practically confirmed by scientist. They demonstrated a recording of two black
holes colliding a billion light years away.
A Century Ago, Einstein’s Theory of
Relativity Changed Everything.
Worse, he had discovered a fatal flaw in his new theory of gravity, propounded
with great fanfare only a couple of years before. And now he no longer had the
field to himself.

So Einstein went
back to the blackboard. And on Nov. 25, 1915, he set down the equation that rules the universe. It
describes space-time as a kind of sagging mattress where matter and energy,
like a heavy sleeper, distort the geometry of the cosmos to produce the effect
we call gravity, obliging light beams as well as marbles and falling apples to
follow curved paths through space.
This is the
general theory of relativity. Since the
dawn of the scientific revolution and the days of Isaac Newton, the discoverer
of gravity, scientists and philosophers had thought of space-time as a kind of
stage on which we actors, matter and energy, strode and strutted.
With general relativity, the stage itself sprang into action. Space-time could curve, fold, wrap itself up around a dead star and disappear into a black hole. It could jiggle like a belly, radiating waves of gravitational compression, or whirl like dough in a mixer. It could even rip or tear. It could stretch and grow, or it could collapse into a speck of infinite density at the end or beginning of time.

A team of
scientists announced yesterday Thursday 11th February that they had
heard and recorded the sound of two black holes colliding a billion light-years
away, a fleeting chirp that fulfilled the last prediction of Einstein’s general theory of relativity.
I’m glad to be
awake in this moment of Stephen Hawkins and the confirmation of General
Relativity.
This is a big
deal and many people will read this discovery of the century millennium to
come.
I will raise my
glass to this.
