To measure the universe’s expansion do scientist need new physics?
Studies prove almost unanimously that the universe is, indeed, expanding. However, different measurements of the rate by which it expands consistently yield different results. Could this mean we need new physics to understand what's going on?
A CONSTANT DISCREPANCY
As far as astronomers can tell, the universe is continuing to expand — and our understanding of how it is doing this needs to expand as well. In fact, recent findings from researchers partnering with NASA suggest that we may need to discover new physics to explain discrepancies between measurements of universal expansion.
