Hello. On the "Ask an Astrophysicist" page on the NASA site, one can read the following: This raises three questions for a layman such as me: 1. Do the scientific community agrees with this answer? 2. Can the virtual gnomes break any rule and fulfill any wish as long as we don't detect them ? 3. Should I trust the rest of the site? EDIT: Somehow the virtual photons transformed into virtual gnomes. I guess it corroborates that they can pretty much "do" whatever they like.
