My congratulations to the LIGO team on their discovery of gravitational waves. It is a result that is at least as important as the discovery of the Higgs Boson. It includes the first observation of gravitational waves, and of two black holes colliding and merging. With LIGO’s increased sensitivity, we can expect many more detections, all improving our knowledge about how the universe works.
These experimental observations are consistent with my theoretical work on black holes in the 1970s. As a theoretical physicist, I have spent my life contributing to our understanding of the universe. It is thrilling to see predictions I made over 40 years ago such as the black hole area and uniqueness theorems being observed within my lifetime. -SH

Altra scoperta epocale

Altra grande giornata per la scienza! Sono state finalmente rilevate le “onde gravitazionali” che confermano ancora una volta la teoria della relatività di Einstein! 
Sono state scoperte grazie ai ricercatori dell’osservatorio LIGO e ci permetteranno di osservare l’universo non più soltanto attraverso lo studio della luce, ma anche da un punto di vista completamente nuovo che potrebbe permetterci di studiare oggetti come i buchi neri in maniera diretta.
Esse sono delle increspature dello spazio-tempo che ogni corpo nell'universo genera in ogni istante e sono solitamente impercettibili, ma gli scienziati statunitensi sono riusciti ad intercettarle osservando le increspature generate da due buchi neri super-densi intenti in un processo di fusione.
Se volete saperne di più allego degli articoli che potreste consultare. 
Dopo il “Pianeta Nove” l’anno “scientifico” si sta aprendo benissimo.

Happy 74th birthday to Stephen Hawking!

Not a year has gone past when Stephen Hawking’s achievements, both in terms of science and popular culture, have not made global headlines.
His work has revolutionized theoretical physicis and cosmology, made him the Commander of the Order of the British Empire and earned the U.S. Presidential Medal of Freedom, all while his body suffers from amyotrophic lateral sclerosis (ALS). 

Here are some of his great thoughts and moments:

“Some people would claim that things like love, joy and beauty belong to a different category from science and can’t be described in scientific terms, but I think they can now be explained by the theory of evolution.”

“The greatest enemy of knowledge is not ignorance, it is the illusion of knowledge.”

“We are in danger of destroying ourselves by our greed and stupidity. We cannot remain looking inwards at ourselves on a small and increasingly polluted and overcrowded planet.”

“It is a waste of time to be angry about my disability. One has to get on with life and I haven’t done badly. People won’t have time for you if you are always angry or complaining.”

“I have lived with the prospect of an early death for the last 49 years. I’m not afraid of death, but I’m in no hurry to die. I have so much I want to do first.”

Stephen Hawking says the Earth is pretty much screwed

Stephen Hawking, one of the world’s most renowned theoretical physicists has said that the likelihood of Earth facing a man-made disaster was a “near certainty” within the next thousand to ten thousand years.

Don’t give up all hope, he went on to say the human race will likely live on — but we need to be extra careful in the next few hundred years.

If machines produce everything we need, the outcome will depend on how things are distributed. Everyone can enjoy a life of luxurious leisure if the machine-produced wealth is shared, or most people can end up miserably poor if the machine-owners successfully lobby against wealth redistribution. So far, the trend seems to be toward the second option, with technology driving ever-increasing inequality.
