1. Novelty
2. it`s Novelty because its something unusual, which draws people in.
4. In a landmark achievement, scientists say they have seen ripples in the weave of the universe, which would provide the first direct evidence that the universe underwent a massive and incomprehensibly fast growth spurt in its earliest infancy.
If the new findings are confirmed, they could very well earn their discoverers the Nobel Prize, says astrophysicist Xavier Siemens of the University of Wisconsin, Milwaukee. Researchers have sought to detect these ripples, known as gravitational waves, for years, and more than a dozen telescopes have been looking for them. Though Einstein predicted gravitational waves, he thought they might not be detectable, and their existence was in some doubt.
Outside scientists' early reaction included some skepticism but also amazement and admiration.
The signs in the data pointing to gravitational waves are "extraordinarily strong, huge huge news … wow," tweeted Dominique Aubert, an astronomer at the University of Strasbourg in France.
The new research provides a glimpse of the universe just after the Big Bang, when it was an infinitesimal fraction of a second old and smaller than the period at the end of this sentence. To explain how the universe evolved from that state to the form it has today, scientists have posited an event just after the Big Bang called "inflation," when space expanded violently and exponentially in the merest sliver of a second.
