This is the third article in a series of four articles each with a separate explanation of different quantum phenomena. Each article is a piece of a mosaic, so every one is needed to understand the final explanation of the quantum astronomy experiment we propose, possibly using the Allen Telescope Array and the narrow-band radio-wave detectors being build by the SETI Institute and the University of California, Berkeley.

Like most of us, politicians don't know much about isotopes. But because they know something about money and jobs, lawmakers from Illinois and Michigan are locked in a battle to convince the federal government that their state and not the other one is the perfect place for a new lab devoted to these unstable atomic forms.

While subatomic particles such as electrons and protons are very small, the devices used to study them are rather large. Consider ATLAS: the particle detector, still mid-construction, is about 45 meters long, more than 25 meters high, and weights about 7,000 tons.
