“Physicists think for purely aesthetic reasons it would have been nicer if there was an equal amount of matter and antimatter in the early universe. Trouble is, this does not agree with observation.”
Sabine Hossenfelder is a theoretical physicist who specialises in the foundations of physics. She is a Research Fellow at the Frankfurt Institute for Advanced Studies where she leads the group on Superfluid Dark Matter. She is the author of Lost in Math: How Beauty Leads Physics Astray, which explores the concept of elegance in fundamental physics and cosmology. Hossenfelder also has a popular YouTube channel called "Science without the gobbledygook" and works partly as a freelance science writer, with her work published in Scientific American, New Scientist, and Nautilus, among others.
“Hossenfelder has done physics and science more generally - and our better selves - a service.” – Jeremy Butterfield, editor of Philosophy of Physics (Handbook of the Philosophy of Science)
