Question
The quantum form of this interaction motivates M-theory and names a theory that implements it with namesake “loops.” For 10 points each:
[10m] Name this interaction that gives rise to the hierarchy problem because it is 24 orders of magnitude weaker than another one.
ANSWER: gravity [or gravitation or gravitational force or gravitational interaction; accept quantum gravity or quantum gravitation or quantum gravitational force]
[10h] Loop quantum gravity seeks to reformulate GR as a background-less one of these theories. Yang–Mills theory exemplifies these field theories in which the Lagrangian is invariant under namesake local transformations in a Lie (“LEE”) group.
ANSWER: gauge theories
[10e] LQG is contrasted with theories of these hypothetical one-dimensional objects that compose all matter. Theories of these objects feature many extra dimensions.
