Half of the 2019 Nobel Prize in Physics was awarded to James Peebles for his work in physical cosmology. Come read about some of his contributions that led to this recognition!
Today’s paper looks at observations of 19 low mass galaxies which appear to contain no dark matter, potentially challenging our overall understanding of galaxy formation.
What is the role of Dark matter in the universe, and are there any alternatives to explain the phenomena we see? Today’s bite explores one such theory.
