Scientists discover cosmic ‘bass notes’

For the first time, scientists have detected a “cosmic bass note” of low-frequency gravitational waves thought to be produced when two supermassive black holes slowly merge, gently stretching and squeezing everything in the universe.

The astrophysics community is thrilled at the discovery as it affirms an astounding implication of Albert Einstein’s general theory of relativity (predicted a century ago) that until now has been far too subtle to detect.

Black holes sit at the center of galaxies. It is believed when two galaxies merge, the black holes at their centers come close together and circle each other in a spinning motion sending giant waves spiraling out.

The waves won’t affect our existence but would provide an insight into the physical world we live in.

According to Einstein, time doesn’t just flow in one direction and space is not empty. Instead, massive objects, including black holes, have powerful gravitational interactions that create ripples across space and time—much like ripples in a pond after you throw a pebble in it.
