Maybe try looking into "Higgs Fields" and "Higgs Bosons."
My (very limited!) understanding is that the Higgs Field is a scalar field pervading all of space--it's interaction with particles via the Higgs Boson gives rise to Mass and is something like the "friction" you are thinking of. I believe they are hoping to observe the Higgs Boson when the latest generation of particle accelerators come online. Might be worth a google?
