For the first time, scientists have detected tiny, rhythmic distortions in space and time. They are gravitational waves caused by the collision of two black holes. And they were predicted by Einstein 100 years ago. The international team says the first detection of these gravitational waves will usher in a new era for astronomy. The research, by the LIGO Collaboration, has been published today in the journal Physical Review Letters.
Here is an explanation of the discovery from British physicist Dr. Ceri Brenner.
