- TL;DR Summary
- Why is the discrepancy in Hubble's "constant" an exciting news which could potentially point to new Physics ( https://www.spacetelescope.org/news/heic1908/ )?
If the Hubble's constant is greater now (to the best of our estimates) than it was in the early universe, doesn't it just imply that the universe's expansion rate is increasing, which was shown by the High-Z Supernova Search team in 1998 that discovered dark energy? Wouldn't this Hubble discrepancy just validate the presence of dark energy, instead of pointing towards new Physics?
