The State of Reality

meOnce in a while somebody should hold a State of the Reality address.

As far as I know, there are at least two new problems for modern physics now:

1. If the structure of spacetime is not as foamy as thought, as indicated by the two-photon observation, what is responsible for quantum jittering?

2. If neutrinos can actually travel faster than light as some experiments suggest, does this mean a total revision of General Relativity — or an exception for special-interest particles?

If we combine these, however: that space isn’t a bumpy ride even at trans-galactic distances and that some particles can go faster than light, then FTL drive or radio doesn’t look so far away.
