It’s finally here! the research paper we have all been waiting for - JWST’s look at the crisis in cosmology, aka the Hubble Tension where we’re getting different answers for the expansion rate of the universe depending on what method we’re using. If you remember i did a video on this when they presents work on the conference circuit back in spring, but we didn’t have any details. Well now we do, this new paper from Freedman and collaborators appeared online today, although its still not gone through peer review, and it has essentially said that they’ve now used JWST instead of the hubble space telescope to do this, there’s no longer a problem, the values for the rate of expansion of the universe with these different methods don’t disagree anymore, at least not within the errors on the measurement. Question I still have is what changed between hubble and JWST data? So I’m going to dive into reading this research paper this week, absorb all the details, and report back in my next Night Sky News episode for August which is coming out next Thursday 22nd, so make sure you’re subscribed so you don’t miss out!
