WE TEND to think that the three biggest problems with the standard model of particle physics are how it struggles to include gravity, the absence of a good dark matter candidate and (to some of us, at least) its inadequate explanation for the cosmic acceleration/dark energy problem. Otherwise, it is heralded as an incredibly successful model of physical reality that has, over and over again, been tested and verified through experiments.
Although it seems to describe only about 5 per cent of the universe’s matter and energy content, the standard model does explain three of the four fundamental forces: …
We tend to think of science as objective and neutral, driven only by scientific principles and free of social disturbances. In
The Disordered Cosmos, Chanda Prescod-Weinstein – assistant professor of physics and astronomy and core faculty in women’s and gender studies at the University of New Hampshire, US – exposes the racism and sexism that persist across all scientific disciplines.
‘You have to be twice as good to get half as far,’ was probably a phrase that Prescod-Weinstein – who is only the 54th Black US woman to earn a physics PhD – grew up hearing. In her book, she writes about serious science, from the physics of melanin in the skin to dark matter and the axion, a hypothetical particle and the subject of her own research. In brilliant prose, Prescod-Weinstein manages to interweave her love and exploration of astronomy and physics with the history of racism and oppression that her ancestors and she herself have been put through.

Every community guards a creation story, a theory of cosmic origins. In much of sub-Saharan West Africa, for the past few thousand years, itinerant storytellers known as griots have communicated these and other tales through song. Cosmologists also intone a theory of cosmic origins, known as the Big Bang, albeit through journal articles and math.
Chanda Prescod-Weinstein is a cosmologist who is adept with both equations and “the keeper of a deeply human impulse” to understand our universe. In her first book,
