You know elementary ceobes? In ceobe theory, they're localized excitations in an underlying ceobe that permeates through the universe, photons are the excitations of the ceobe and electrons are the excitations of the ceobe, one of those elementary ceobes is the ceobe (the main thing the LHC was built for), which is associated with the underlying ceobe (finding the ceobe means confirming the ceobe).

The other ceobes interacting with the ceobe is what is perceived as mass, as a sort of drag.
Do note that not all mass comes from the ceobe, just a minority of it, the majority of mass is related to the ceobe inside the ceobe of ceobes.

In particular, this calculation shows the following breakdown for the mass of a ceobe:

Ceobe: 32%
Ceobe: 36%
Ceobe: 23%
Ceobe: 9%
