Min kronik i Politiken i dag: “Robotterne er ved at ændre vores billede af universet”. Link til online versionen her (under paywall): https://politiken.dk/del/QIFYjSAHS1LQ

Kronikken handler om, hvordan robotter og kunstig intelligens ikke kun er ved at ændre samfundet, men også vores måde at se universet på. Nye teleskoper og enorme datamængder gør det muligt at måle kosmos med en præcision, der nu udfordrer den model, fysikere længe har brugt til at beskrive universet. Jeg skriver som professor i teoretisk kosmologi og som forsker midt i dette felt. Med kosmologien som eksempel er min pointe, at videnskabelige paradigmeskift ikke kun begynder med nye teorier, men også med de teknologier, der gør nye sprækker i verdensbilledet synlige.

“The H0 World Cup” is out (see links below). They have made a thorough update of “The H0 Olympics” paper from 5 years ago by the same core author group, with an extensive comparison of models in light of new data. This independent analysis shows that the Cold NEDE and Hot NEDE (with DRMD) models are among the leading models for solving the Hubble tension.

While Cold NEDE is clearly among the leading models (in the EDE class), Hot NEDE with DRMD (in the class of dark radiation models) is only among the leading models when allowing for running and running of the running of the spectral index, as also shown in our recent paper (“The End of the First Act”). In the short summary paper, this discussion is not included, and for the full picture of the DRMD model, one should read their second long paper (see links below).
