Einstein’s theory confirmed again: Scientists detect gravitational waves for second time
They’ve done it again. “It really feels like we are maturing as astronomers,” said Gabriela González, a spokeswoman for LIGO’s scientific collaboration and an experimental physicist at Louisiana State University. “The actual astrophysical rate that nature has chosen is near the high end of the range spanned by the pre-LIGO estimates.” The discovery allows researchers to start taking a broader view on the diversity of black-hole merger events that may pervade the cosmos, said Kamionkowski, who predicted that thousands more would be discovered in the next decade. “There’s only so much that you can learn from one black hole merger.” These events also offer scientists a singular method for probing the limits of Einstein’s long-lived theories about the universe, Kamionkowski added. “We don’t want to just know that we saw black holes, we don’t want to just know the masses — we want to know where on the sky they came from,” Reitze said.
