David Kaiser thinks the dark matter puzzle is getting closer to being solved. Nearly a century of observations, from galaxy clusters to the cosmic microwave background, have built a compelling case for dark matter's existence, but in recent years, the leading candidates for this mysterious matter have been coming up short.. Enter black holes. Tiny ones. David explains how so-called primordial black holes that formed in the first moments after the Big Bang could possibly be all our dark matter… if they exist at all. Fortunately, this is a testable theory, and David explains the exciting new experiments that could potentially lay this cosmic mystery to rest.
David Kaiser is a professor of physics and the history of science at MIT. His research spans the history of modern physics, cosmology, and the foundations of quantum theory. He is the author of several books, including How the Hippies Saved Physics, and is a frequent contributor to public conversations about science and its history. He is also featured in NOVA’s documentaries Einstein’s Quantum Riddle and Decoding the Universe.
Particles of Thought is hosted by Hakeem Oluseyi, an astrophysicist, author, STEM educator, multi-patented inventor, science journalist, TV personality, science communicator, and inspirational speaker. His research is based on "hacking stars" to understand our universe better and develop innovative new technologies. Oluseyi's work has resulted in 11 patents and more than 100 publications covering contributions to astrophysics, cosmology, and plasma physics and the development of space missions, observatories, focal plane instruments, detectors, semiconductor manufacturing, and ion propulsion.
