matter modelAbstract
A new model for dark matter is put forward which consists of uniform droplets of Bose Einstein condensate.
In this model, structure forms rapidly, shortly after the hot big bang plasma de-ionises.
The model also produces modifications to the expansion rate before droplet formation that affect the measurement of cosmological parameters from Cosmic Microwave Background data.
The model could contribute to explaining why observations at high redshift see anomalously high structure formation and predict low values for the Hubble constant.
