The invisible substance that holds our universe together
In short: While atoms make up everything we see, they represent only a small fraction of reality. This lecture explores the evidence for dark matter and the ongoing quest to detect it.
Roughly 85% of all matter in the universe is not made of atoms. Known as dark matter, this invisible substance does not interact with light like normal matter does, yet it exerts a gravitational pull that shaped galaxies and large-scale cosmic structures.
Dr. David E. Kaplan provides historical context on how scientists identified these properties and discusses current laboratory efforts to achieve direct detection of this elusive material.
