Paper day. In a proposal last year we minimally describe the entire dark sector using two scalar fields, motivated by an approach to the cosmological constant problem. We recently fit this model to cosmological data and find it works better than LCDM, because it resolves the Hubble tension.

This is a lovely experiment and all, but didn’t the resolution to this puzzle come from the theory side? 🧪⚛️

🚨 Oh wow. Calling the side of the world where it's still dark. Look up!! Look up!! The mega sun burp has arrived 😮 #AuroraAlert Notes: Get far away from streetlights & look for a silvery shimmer in the sky. Prop your smartphone up on a wall to take a long exposure & reveal the colours. 🤩 🔭🧪

The attack on basic science in the USA is real: The National Science Foundation just killed half of the Nobel prize winning LIGO experiments (essentially meaning: LIGO can no longer see where a gravitational wave comes from, just that it was there)

“The value today of philosophy to physics seems to me to be something like the value of early nation-states to their peoples…the insights of philosophers have occasionally benefited physicists, but generally…by protecting them from the preconceptions of other philosophers.” - Steven Weinberg

Well, looks like March 19th is going to be an interesting day in the cosmology world. Two big surveys - DESI and Euclid - have coincidentally chosen the same day to announce some data releases and related exciting results in big press releases! And the Arxiv will be flooded on March 20th ... 🔭🧪

This Harper's article is written by a woman at a social event, perhaps a cocktail party, in 1941. Who will "go nazi" when given the opportunity for gain by doing so? Remarkably, but unsurprisingly, the answer is what you're seeing in America in 2025. See for yourself. harpers.org/archive/1941...

#PlanetaryParade fans: all 7 planets are now in the sky for ~1hr after sunset. Mercury joins the pack low on the Western horizon but it's hard to see, hiding in the sunset glare with Saturn. Tried to catch it this evening, but the weather Gods had other plans so here's Venus and Jupiter instead! 🧪🔭
A view overlooking a city.  Up above the sky is clear with two bright stars (Jupiter up above and Venus to the right).  There is a big bank of clouds below Venus where Mercury and Saturn should be.
