The scientific community believes that their discovery will ensure them a Nobel Prize.
For years, scientists were striving to find facts proving the existence of gravitational waves. Almost a century after Einstein’ exposition of gravity, specialists detected waves for the first time and revealed them to the world as a short chirp sound. Such a sound resulted from the collision of two supermassive black holes that are 1.3 billion light-years away from the Earth.
Scientists say that when a body moves round a black hole, the energy produced in form of gravitational waves is six times as powerful as the energy generated from thermonuclear reactions.
Of course, it is our up-to-date technologies that allowed us to detect and hear gravitational waves. In 2011, gravitational wave 'hunters' were reinstalled. Advanced LIGO is four times as sensitive as the previous incarnation. It is the largest apparatus on our planet with 4-km arms.
The devices are constructed to detect a wave going through our planet as a result of a black hole merger. Green light in the picture is a wave.
LIGO (Advanced Laser Interferometer Gravitational-wave Observatory) is actually two facilities, one in Louisiana and the other in Washington state; and both of them detected these waves.

For nearly a century, the US-based weekly periodical Time has closed out the year by selecting the person who has had the most significant impact on the global stage—not necessarily a positive one. This year, the magazine's cover features Donald Trump, who recently won the US presidential election. Let's find out who else was honored by Time and in which nimonations.
Following his election victory, Donald Trump, a billionaire himself, once again decided to include prominent magnates in his administration, as he did during his first presidential term. As a result, Trump's current cabinet features seven billionaires, making it one of the wealthiest in US history. Let's find out who these billionaires are and the roles they have been assigned.
Not long ago, the United States held a presidential election, where Donald Trump emerged victorious. Today, he is recognized as the wealthiest American leader in the country's history. Let's take a closer look at other former US presidents who also achieved significant financial success.
