In 1964 three teams proposed related but different approaches to explain how mass could arise in local gauge theories.

Its added mass arises from the added potential energy stored within it, which is bound in the stretched chemical (electron) bonds linking the atoms within the spring.

It was shown that masses of elementary particles can arise as a result of interaction with the superfluid vacuum, similarly to the gap generation mechanism in superconductors.

The blurry mass arose, crawled forward, edged past the Indian, stepped cautiously ashore.

Then, abruptly, the rockets cut off, and something dark plunged downward, and the rockets flamed again and a vast mass of steam arose from scorched ground.

One important non-collider effort is the determination of the neutrino masses, since these masses may arise from neutrinos mixing with very heavy particles.

The Higgs mechanism proposes that mass arises when particles, such as protons, interact with the Higgs field, a sort of force field that permeates everything.

In the theory of superfluid vacuum, masses of elementary particles arise from interaction with a physical vacuum, similarly to the gap generation mechanism in superfluids.

Next instant Hans vanished, and from the centre of that fluffy, stinking mass there arose a frightful yell.

Now, out of the seething, bubbling, merged mass arose a new shape, Chanchukian in form but at first hairless and featureless.
