How is it possible that phi is everywhere?

Answer 1

We might be able to answer this question if you'd explain what the heck you mean by "phi", or even if you'd better define "everywhere" we might be able to guess what you mean by "phi".

For example, if you mean "Why is there a Phi Orionis, and a Phi Ursae Majoris, and ..." then it's because there are a lot of stars in each constellation and only so many Greek letters.
