"The "frequency" of a solid object is many times that of light,..."
In general sure, but then again you didn't specify what wavelength "light" you were talking about.
Well, even a proton has a higher freq than the beefiest gamma ray, and when you get up to objects the size of a golf ball, that freq is not comparable to light.
Does not matter, because the "scientist" in the article thinks that solid matter has zero frequency. Hmm, if it did, there's an easy way to get to Absolut Zero.
