First Sloth in space! Zero-G indicator on today’s mission to the space station was a Sloth 🦥
Quote from today’s review of the local H0 measurements: JWST “observations provide the strongest evidence yet that systematic errors in HST Cepheid photometry do not play a significant role in the present Hubble Tension”: https://arxiv.org/abs/2308.10954
Groningen group with a new paper *not* finding evidence of unknown systematics being the source of the Hubble tension. This further strengthens the case for early times (pre-recombination) new physics, like New Early Dark Energy (NEDE): https://arxiv.org/abs/2308.05157
A reminder not to believe we know it all and not to stop exploring the wonders that nature might hide for us.
