On February 11, 2016, a team of scientists announced that they had heard and recorded the sound of two black holes colliding 1.2 billion years ago, proving the last prediction of Einstein’s general theory of relativity in which the space-time continuum is not static but dynamic, able to stretch and shrink.
This research finding makes me re-realize what an amazingly exceptional mind Albert Einstein possessed. Such a slightly kooky and weird theory (though it can be easily applied to smaller-scoped physical entities) could have been formed only by a mind that can transcend humdrum and trivial (compared with the unfathomable vastness of universe) human struggles and worries. I am also amazed by more than 1,000 scientists from all over the world involved in the LIGO (the Laser Interferometer Gravitational-Wave Observatory) scientific project, who must have made selfless and almost obsessive efforts to accomplish the objective. Time, which humans tend to think of as rigidly inexorable, is actually fluid, being influenced by great energy and mass. All is flux; nothing stays still, as Heraclitus said.
