Los Angeles was jolted awake Monday by a relatively powerful magnitude 4.4 earthquake, but there were no reports of damage or casualties. "I woke up to feel the building swaying from side to side," Wes Lashley told KCAL 9 news, while . The temblor was initially estimated as a 4.7 magnitude by the US Geological Survey (USGS), but later downgraded to 4.4.

In a major discovery for understanding the origins of the universe, US scientists said Monday they have detected echoes of the Big Bang 14 billion years ago. The "first direct evidence of cosmic inflation" was found with the help of a telescope at the South Pole, and was announced by experts at the Harvard-Smithsonian Center for Astrophysics. The detection of these gravitational waves represents the last untested element of Albert Einstein's general theory of relativity, filling in a major gap in our understanding of how the universe was born. The gravitational waves are ripples that move through space and time, and have been described as the "first tremors of the Big Bang." Their detection confirms an integral connection between quantum mechanics and general relativity.
