The Restaurant at the end of the universe. Impossible!

Asked by PaulCaswell in Math & Science

Tags:

If I am not mistaken, in this article:

http://www.sciencedaily.com/releases/2007/04/070402122514.htm

they are describing a method of detecting the presence of a photon without affecting it.

Why does this sound like something impossible to me? How can a particle record the presence of another particle without affecting it? If it is affecting it, in what way?
