ESA have announced some new results on the expansion of the early universe that seem to indicate that the difference between the measurements of the Hubble - Lemaître 'Constant' as measured locally by SN1a standard candles and that measured using the cosmic microwave background may be real and not measurement errors.
The news release on the link below proposes that one reason for the change they have measured is that the density of Dark Energy increases with time. The obviously requires some new physics but then we know little if anything about the physics of Dark Energy.

The non amateur stuff. Hawking, black holes, that sort of thing
