The video discusses the concept of dark matter, which constitutes 25% of the universe's energy and matter, compared to the 5% made up of ordinary matter. Dark matter is detected through its gravitational effects, and its existence challenges our understanding of gravity. Historical examples, such as the discovery of Neptune and the precession of Mercury, illustrate how missing mass and revised theories have shaped our understanding of the universe. The video raises questions about whether dark matter exists or if our theories of gravity need revision.
