The Royal Swedish Academy of Sciences has decided to award the Nobel Prize in Physics 2017

with one half to Rainer Weiss and the other half jointly to Barry C. Barish and Kip S. Thorne at LIGO/VIRGO COLLABORATION LIGO Scientific Collaboration

“for decisive contributions to the LIGO detector and the observation of gravitational waves”.

On 14 September 2015, the universe’s gravitational waves were observed for the very first time. The waves, which were predicted by Albert Einstein a hundred years ago, came from a collision between two black holes. It took 1.3 billion years for the waves to arrive at the LIGO detector in the USA.

The signal was extremely weak when it reached Earth, but is already promising a revolution in astrophysics. Gravitational waves are an entirely new way of observing the most violent events in space and testing the limits of our knowledge.

LIGO, the Laser Interferometer Gravitational-Wave Observatory, is a collaborative project with over one thousand researchers from more than twenty countries. Together, they have realised a vision that is almost fifty years old. The 2017 Nobel Laureates have, with their enthusiasm and determination, each been invaluable to the success of LIGO. Pioneers Rainer Weiss and Kip S. Thorne, together with Barry C. Barish, the scientist and leader who brought the project to completion, ensured that four decades of effort led to gravitational waves finally being observed.

Unasema nini?

It took more than a thousand million years for these gravitational waves to arrive here on Earth.

It was completely dark. But not completely still. Tremors from two black holes colliding shook all of spacetime. Like ripples from a pebble thrown into water, gravitational waves from the impact spread through the cosmos. It took time for them to reach us. Despite moving at the speed of light, the fastest possible, it took more than a thousand million years for these waves to arrive here on Earth. On 14 September 2015, at 11.51 CET, a gentle wobble in the light pattern at America’s twin LIGO laboratories revealed the drama that unfolded long ago and far away, 1.3 billion lightyears from Earth.(SOURCE: Nobel prize pages)

Mbona Stephen Hawking hapewi ii prize bana? Its overly due apewe bana

For what? He has advanced theories, which have not been tested.

Acha ukutwe na ilikuwa kwa thread ingine jana

I don’t believe what this scientists feed us, traveling at the speed of light and still take hundreds of millions of yrs to get here! Argggg, I give up

If it’s true then we ain’t alone in the universe. Something will find us

maybe we are already found and to “them” we are like tuthigiriri…:slight_smile:

Just wondering is speed relative to size?


Ya literature na chemistry inapewa nani? I would want to propose our very own resident chemical farter @Adeudeu

Now how did they know that it happened thousand of million years ago. They just detected the waves of which they don’t know where it originated, the initial magnitude and its speed
