Laser Interferometer Gravitational-Wave Observatory (LIGO) doesn’t stop to amaze us. After their last-year discovery, perhaps the biggest one in this century, detection of gravitational waves, they went a step further. Now LIGO can produce it!
To make things even more astonishing, exactly on this day in 2016 Laser Observatory announced the whole world the biggest discovery in the 21st century. They manage to detect ripples in the fabric of space-time, known as gravitational waves, after tracking the merging of two black holes. The coincidences don’t stop here: almost 100 years ago, Albert Einstein predicted ripples that are produced when massive objects warp spacetime.
The supersensitive detectors which are consists of a pair of crossed, 4-kilometer-long rulers, now turn out to be the best producer of gravitational waves. Physicists assumed as the detector were able to capture waves that also means it can generate them. So they developed a quantum mechanical model of how the stretching of space affects to light waves bouncing back and forth in one of LIGO’s arms. Then they set up detectors sensitivity to produce ripples.
After the test, detector indeed generated tiny, optimally efficient ripples. The challenging experiment succeed. These waves aren’t large, but the fundaments of detectors confirmed: when it couple to gravitational waves, it’s going to go both ways.
Further experiments might give us a better view of quantum activity, which then leads to outstanding possibilities, such as building quantum computers or revolutionary change in understanding the physical universe. LIGO is in the process of upgrading their technology, so we can only imagine what new they can bring us. Perhaps even find the clues about dark matter and dark energy.
