Hi Kevin, just wanted to ask,
I was following some public lectures by several professors last week,
and the last one was about the Higgs boson.
In that space is not empty and filled with the Higgs field.
Today I have been studying that stuff..
and found some interesting mass related problems.
Did you have thoughts about that?

Ever met the man?
