Defining Dark Matter
Professor Graham Kribs research into dark matter highlighted in an Around-the-O article:
Defining dark matter isn’t easy. It is thought to be particles that can only feebly interact with the known particles of the universe. The particles, whatever they are, are tied to the expansion of the universe, beginning with the Big Bang.
Scientists have strong evidence from observations of the first light, when the universe became transparent to visible wavelengths of light. So far, however, the evidence has been revealed only through dark matter’s gravitational effects on galactic and larger scales.
Finding dark matter, Kribs said, is about advancing fundamental knowledge about the universe.
