Why Physics Can t Totally Explain the Universe s Expansion | SciShow News

Astronomers have gotten pretty good at calculating how fast the universe is expanding, but new measurements don’t line up with the predictions of well-tested laws of physics. Now scientists have a new question to ponder: Why are these numbers so different? SciShow has a spinoff podcast! It s called SciShow Tangents.
