• A new preprint paper challenges a high-profile cosmology study recently published in the journal *Nature*, claiming the original research contains an "elemental" mistake. • Physicist Sawala argues that the error likely slipped through the traditional peer-review process, which relies on a small number of reviewers who may miss critical flaws. • This dispute highlights the growing importance of preprint servers like arXiv.org, which allow the broader scientific community to vet findings in real-time.
