Astronomers claim universe has "cosmic glitch"

#cosmology #physics #BigBang
Science news outlets around the world have reported a possible "cosmic glitch" in the universe.
We chatted with one of the authors of the paper that made this claim.
Niayesh Afshordi and I discuss what motivates it, how it was tested, and how it might be further tested in the future. Most importantly, what impact it might have on the very origin of the universe. Might we have to rethink cosmology and consider what was before the Big Bang?
