The universe began with a bang, not a bounce, new studies find

Scientific American reports on new studies which found that the universe likely began with a bang, not a bounce. The article quotes one of the studies co-authors, Will Kinney, professor of physics, and an expert on cosmology. “I feel like we’ve demonstrated something fundamental about the universe,” Kinney says, “which is that it probably had a beginning.” That implies a big bang occurred at some point, even if that event happened many bouncing universes ago, which in turn suggests that it took a singularity to get everything going in the first place.
