You can hear this breakthrough. “Whoop”. So it sounds when waves, kicked off 1.3 billion years ago in space, arrive on Earth. When, on September 14, 2015 in morning at 5 o’clock local time in two detectors in Louisiana and Washington simultaneously made “whoop”, sensation was perfect. It was proof of what Albert Einstein prophesied: that re are gravitational waves. By way, some people say that signal sounded more like “Chirp” (but listen to it). Superlatives are allowed in this history of science. Because this direct proof has stuff to change astrophysics.

A Nobel Prize for this was “overdue”, many say, and are pleased that US researchers Rainer Weiss, Barry Barish and Kip Thorne will get it. “Something unfair,” monies ors, finally, more than 1,000 scientists from all over world have worked for 40 years to capture extremely weak cosmic signals. But Nobel Prize only allows a maximum of three winners. Ors find that Einstein himself deserves Nobel Prize. But he already got one, did not seem to have any evidence, nor did he believe in his lifetime that gravitational waves could be snapped at all.

Posthumously, no one gets greatest honor in science anyway. This is also reason why Ronald Drever, one of major gravitational wave hunters, is not among honoured. Drever died in March of this year. And so American born in Berlin gets Rainer – called by many Rai – Weiss from Massachusetts Institute of Technology (MIT) which is one half of physics Nobel. The ors share his colleagues Barry Barish and Kip Thorne of California Institute of Technology (Caltech).

All three are among pioneers who have developed and built machine with which detection succeeded: Laser Interferometer Gravitational Wave Observatory Ligo. White was first to paint a highly sensitive measuring station. For decades he around how to filter out noises from universe that are not gravitational waves. In 1980s, Thorne made sure that White’s vision became a reality, and Barish saved billions of projects in 1990s before early years. This is only reason why waves 2015 discovered and Einstein’s prediction could be proven.

When he presented his general ory of relativity in year 1915, he drew a completely new image of gravitation. Previously, it had been considered that attraction would be between two masses without any time delay – no matter how far y are from each or. Einstein, on or hand, believed that gravity had arisen because mass crookednessed space and time. The decisive point is that time of day cannot be quickly bent, but only at speed of light.

Now, if re are mighty masses in universe, right dents should hit space-time, light will rush through cosmos and cross orbit of Earth. The deformations are extremely small and not perceptible to people. It is clear that y actually exist, since super detectors in Louisiana and Washington have captured decisive signal. Whooouuuup!

The waves, which were barely heard for first time for more than two years, consist of energy that radiated into space when two black holes collided and merged 1.3 billion years ago. Simply put, re was a oomph in space that was so formidable that waves of vibration were still measurable for an eternity later. Four furr echo signals of cosmic collisions registered Ligo detectors and sister project Virgo to this day. The latest signal came last week.
