National Virtual Observatory
scubacuda writes "According to this Technology Review article, U.S. astronomers (compliments of a $10M grant from the National Science Foundation) are building a National Virtual Observatory to make accessible terabytes of astrononomical data to a web browser. One interesting challenge is how the scientists are going to query so many *different* distributed databases (which they're leaving in their respective places to avoiding clogging network bandwidth)."
I would rather say people should look at environmental pollution and global warming if they wish to survive 500 years or so.
