Where did the universe come from, and how is it evolving? Those questions made little sense a century or so ago, before the existence of the Big Bang theory.
"When Einstein was developing his general theory of relativity in 1915, the scientific picture of the universe was that it was static and eternal," Dr. Lawrence Krauss, professor of physics at Arizona State University and the author of "A Universe from Nothing" and other books, says in a recent interview with HuffPost Science editor David Freeman (click link above). Now, Krauss says, we know that the universe had a beginning--and that it's expanding "faster and faster."
But what is the ultimate fate of the cosmos? Will it expand forever?
"We don't know what the ultimate future is," Krauss says. But evidence suggests it may keep expanding forever, he says, ending with "a whimper instead of a bang."
