Discovery of gravitational waves would be one of century’s biggest breakthroughs in physics
According to a rumor doing the rounds in the market, physicists could have finally found ripples in the fabric of spacetime called ‘gravitational waves’. Though, nothing has been confirmed by the scientists at the Laser Interferometer Gravitational-Wave Observatory (LIGO), a California lab that is looking for these waves.
In an email, Gabriela Gonzalez, physicist and spokesperson for LIGO, told Tech Insider said, “We will share results when ready but have nothing yet — it takes months to analyze the data, interpret results and review them”. However the possibility has left many scientists thrilled.
The gravitational waves discovery would be among the biggest breakthroughs in physics, seen in a century.
Here is what gravitational waves are. Published in 1915, Albert Einstein's theory of general relativity suggested that quite huge objects can curve the spacetime fabric around them. Somehow, its alike a bowling ball sinking into and deforming a taut sheet. Thus, it’s known that spacetime can be warped, and has some crazy implications.
For example, when a huge object abruptly accelerates, it must result into creation of ripples through spacetime, known as gravitational waves, alike the ripples raindrops forms on a lake’s surface.
According to physicists we should be able to detect these ripples at the time of a star explosion, or at the time of collision between two huge objects, such as when two black holes merge.
Their detection is not at all easy. In a hope to detect them, physicists have been using quite complex instruments.
A big, L-shaped, laser-powered detector LIGO has been searching for gravitational waves since it opened in 2002, to no benefit. But in September, a more powerful, superior LIGO went online.
In case gravitational ripples have been passing by our planet, such instruments must detect disturbances in an extreme sensitive laser beam setup.
