The James Webb Space Telescope will also help us to get to the bottom of the Hubble tension #JWST #HubbleTension

The story of #JWST is, I think, the story of humanity's good side. https://t.co/9dW7AnpaIR pic.twitter.com/puSQ7w7yrP

New SH0ES results find H_0 = 73 pm 1. A 5-sigma tension with Lambda-CDM. Exciting!

Can we resolve the Hubble tension with a first order phase transition in the early universe? See our paper: https://t.co/m486cvjXy9
Here the false vacuum energy of a scalar field provides a short burst of repulsion before it decays via the nucleation of true vacuum bubbles.

Gravitational atoms could form from Planckian Interacting Dark Matter (PIDM) in the early universe — we computed this and the gravitational wave signature of their decay: https://arxiv.org/abs/1903.12168

An exciting thing about NASA’s selection of the SPHEREx mission, it is that they claim to probe non-Gaussianity parameter |f_NL|<1 thus being sensitive to the simplest curvaton model f_NL = -5/4
