  One of the leading issues in quantum field theory and cosmology is the
mismatch between the observed and calculated values for the cosmological
constant in Einstein's field equations of up to 120 orders of magnitude. In
this paper, we discuss new methods to potentially bridge this chasm using the
generalized uncertainty principle (GUP). We find that if quantum gravity GUP
models are the solution to this puzzle, then it may require the gravitationally
modified position operator undergo a parity transformation at high energies.
