Scientists discover novel way of detecting Einstein's gravitational waves
They built a 'super-sensitive gravitational wave detector' to check twice for the ripples in space.
More than 60 years after the passing of Albert Einstein, he continues to make waves in the scientific community. Literally.
Back in 1915, Einstein penned his theory about gravitational waves, which is basically described as a ripple in the fabric of space. Imagine space is a trampoline. Now imagine kids running around that trampoline. They're going to send ripples across that surface. This is similar to the theory of gravitational waves: two rapidly orbiting black holes will create ripples in space.
Einstein may have predicted it in 1915, but it wasn't until more than a century later, in 2016, when scientists were finally able to prove their existence. The news, dubbed a "watershed moment" in modern science, made international headlines.
Ever since then, physicists have been working on better ways to detect gravitational waves, and this week they found one. An international team of scientists have invented a super-sensitive gravitational wave detector. The novel aspect of their detector is that it's actually just a new way of operating existing detectors. It simply uses the detector twice. The new design was published in the science journal Nature this week.

This is just the latest in a string of discoveries related to Einstein's work. Just last month, his theory of relativity taught scientists how to uncover an alien planet three times the size of Jupiter. In addition, a new television series on the National Geographic Channel (which we are recapping each week) is introducing Einstein's theories to a whole new generation of budding scientists.
"The interest in Einstein does not fade into history," said Professor Hanoch Gutfreund of Hebrew University in Jerusalem, where Einstein's archives are kept. "If anything, the interest in Einstein increases with time. It's greater now."
