Perhaps virtually 100% of physicists out there believe that we live in an 'accelerating universe', but as a person who's been researching the topic for a while, it seems to me the only evidence we have is based around redshift. I know redshift is a good enough argument to convince even Einstein, a radical thinker that the universe isn't static but expanding... but hey, what if there is another plausible explanation for redshift? I've been reading up on gravitational redshift, and could that be the cause of the redshift we see in absorption spectra of distant stars? Gravitational redshift is caused by time dilation, which would result in similar observations to what we see in absorption lines... A Google search yielded me this link with another possible explanation: It's on the Nature website so it's no joke!. Though the paper the article is based around isn't peer-reviewed, CTRL-F the name "Aranoff" and you'll find a comment by the person describing a similar peer-reviewed study. So, what do y'all think?
