Q & A
  • What is the hierarchy problem in particle physics?

    -The hierarchy problem refers to the large discrepancy between the fundamental mass scales in particle physics, specifically the Planck mass, which is around 10^19 times the mass of a proton, and the much smaller mass scales of particles we observe in the world around us.

  • What is the role of supersymmetry in addressing the hierarchy problem?

    -Supersymmetry is a theoretical concept that proposes a partner particle for every known particle, with a different quantum mechanical spin. This symmetry principle can naturally explain why particles have such low mass, potentially resolving the hierarchy problem.

  • What is the Hubble tension and why is it significant?

    -The Hubble tension refers to the discrepancy between different methods of measuring the expansion rate of the universe. It is significant because it suggests that there may be unknown physics affecting our understanding of cosmological models.

  • What contribution did Frank Wilczek make to the field of physics for which he won the Nobel Prize?

    -Frank Wilczek, along with David Gross and others, made profound contributions to the understanding of the strong nuclear force, specifically the discovery of asymptotic freedom in quantum chromodynamics (QCD), which explains why the strong force becomes weaker as quarks get closer together.
