- Why is that hard to believe? Directional subnoise effects, given enough
- time (and we're talking teraseconds), can overwhelm noise. That was, for
- example, the principle behind COBE's recent 3K anisotropy detection.

- No kidding. What do you think I've been talking about? I have not
- specified *any* scenario, simply because no one knows, me least of all.

- Parity violation on the atomic level is currently a lively cottage
- industry. Numerous such effects are known. Without even looking, I
- ran into a new World Scientific conference proceedings on this topic
- which showed up at the Penn library this past week.
