Is there really a Hubble tension? — mentioned by astro123

Not to go into much detail, but these author's views are not shared broadly in the cosmology community. There was a recent paper [1] put on the arxiv that talked a bit about this. I'm not an expert on supernova cosmology (I work on cosmology using other methods) but people I know who are experts claim there are issues. There are also a ton of other reasons to think that the universe is flat (see the CMB [2]) and to think that there is dark energy (large scale structure [3]). We still have no idea what DE is and it might not be an "Energy" but rather some modification of gravity or something…
