Dear MEL Topic Readers,
Gravitational waves open 'a window on the universe,' scientists say
Homework done! It took just a century to detect what Albert Einstein
predicted to exist, the gravitational waves. They are ripples in space-time
which were created by the merging of two black holes, according to the director
who represented the observatory, LIGO in the US.
What they “heard” was the sound when two black holes clashed over a
billion years ago in a far-away galaxy. The waves created by the collision had traveled
through the universe, passing through everything before they reached Earth.
How is that possible? What is significant about this detection?
Enjoy reading and learning this 100-year pursuit of a wise-man’s
prediction.
