"There was a clue in the title of one of Albert Einstein’s most famous research papers, published in 1905: ‘Does the inertia of a body depend on its energy content?’ This was the paper in which Einstein suggested that there was a deep connection between mass and energy, through what would subsequently become the world’s most famous equation, E = mc2.
We experience the mass of an object as inertia (the object’s resistance to acceleration) and Einstein was suggesting that the latter is determined not by mass as a primary quality, but rather by the energy that the object contains.
So, when an otherwise massless particle travelling at the speed of light interacts with the Higgs field, it is slowed down. The field ‘drags’ on it, as though the particle were moving through molasses. In other words, the energy of the interaction is manifested as a resistance to acceleration. The particle acquires inertia, and we think of this inertia in terms of the particle’s ‘mass’."
