What Shape Is the Universe? A New Study Suggests We’ve Got It All Wrong https://www.quantamagazine.org/what-shape-is-the-universe-closed-or-flat-20191104/ … via @QuantaMagazine
Fascinating data, though I didn’t like how wordy it was to get to the meat of it. The geometry is calculated by how much the CMB is gravitationally lensed. New data deviates 3.5σ from ‘flat universe’ expectations. What this implies is currently being debated.

If the universe's geometry's spherical, shouldn't its expansion be decelerating? Yet it's in fact accelerating. How to reconcile?
