- There is some speculation that tests of Planck-scale physics may be closer
- than is usually thought. See recent papers by Ellis, Mavromatos, and
- Nanopoulos (some in Physics Letters, and some on the hep-ph bulletin board).
- The part that I understand is that M(K)/M(P) ~ 10**-19, while
- dM/M(K) ~ 10**-17, only a factor of 100 larger. M(K) is the mass of the
- K-meson, dM is the KL/KS mass difference, and M(P) is the Planck mass. If
- the speculation is correct, then tests could be performed in the next decade.
