We are used to think about the universe as a structure which started with a Big Bang and then expanded. Sir Roger Penrose, who received the 2020 Nobel Prize in Physics, has developed an alternative theory of the universe based on Einstein’s Theory of General Relativity which is called "Conformal Cyclic Cosmology". In this new model we don’t have one single Big Bang, but an iteration of infinite cycles (or aeons) of expansion and cooling, each beginning with a “big bang” and ending in a “big crunch”.
Science Journalist Jens Degett interviews Professor Niels Obers, Director of the Nordic Institute for Theoretical Physics (NORDITA) and professor at the Niels Bohr Institute in Copenhagen, on Roger Penrose’s theory and how much evidence is needed in order to change the general view of a central paradigm which is written in our school textbooks. What if Penrose is right? What consequences or perspectives will it have for us?

Vores levende univers
This podcast on our living universe is recorded in Danish. We will try to make an English transcription as soon as we we can get a suitable transcription tool.
Vores levende univers
Der sker i disse år så meget inden for forskning især inden for biovidenskaberne. Vi studerer på livet løs hvordan liv fungerer, men hvad liv egentligt er, det er stadig et godt spørgsmål. Hvis man føler sig hægtet af, så er der en god anledning til at få et overblik over emnet lige nu - for Gunver Lystbæk Vestergård har skrevet en bog, som udkommer på Peoples Press i disse dage med titlen
Vores Levende Univers - videnskabens søgen efter rumvæsener og alt livs oprindelse.
Hør videnskabsjournalist Jens Degett interviewe forfatter og videnskabsjournalist Gunver Lystbæk Vestergård om hendes bog og hvad der i øvrigt sker med vores erkendelse af liv i universet.

Extreme Light Infrastructure
One of the most powerful and advanced laser research institutions in the world is situated in Hungary. It is called the Extreme Light Infrastructure (ELI) The Lasers of ELI can generate light pulses so bright that they can capture femtosecond and attosecond events in the molecular and atomic range. This can be used in a number of very different research disciplines from medicine and life science to climate and material research. More than 600 researchers work here, but many more are visiting from all over the world.

[Best of] August Krogh's Nobel Prize: Respiration is still a key research topic.
More than 100 years ago August Krogh received the Nobel Prize for showing how oxygen is transported from the lungs through the blood into the small capillaries in the muscles. Details of the mechanism and how it is regulated are still central topics of research a hundred years after and understanding respiration is still a matter of life or death.
In this interview science journalist Jens Degett had the opportunity to talk to, one of the world's leading physiologists professor Christopher Ellis from the University of Western Ontario (Canada) about how August Krogh's 1920 Nobel Prize greatly influences physiological research even 100 years later.
In addition to Nobel Prize class research, August Krogh founded one of the first biomedical companies in Denmark. The company would later become Novo Nordisk, which is now among the world's largest manufacturers of biomedicine and insulin.

Om Science Stories
Science Stories fortæller historier om videnskab baseret på nysgerrighed og fascination af viden og indsigt, men vi kan også være kritiske og stille spørgsmål ved veletablerede dogmer. Vi stræber efter at forstå grundlaget for viden og sætte den i perspektiv. Redaktionen er uafhængig og ikke underlagt udefrakommende politiske eller kommercielle interesser.
