【万物简史】PART III CH 11马斯特·马克的夸克（10）

Hints:
the Standard Model
strand
oscillate

The Standard Model is not only ungainly but incomplete. [-1-], it has nothing at all to say about gravity. [---2---] Nor, as we've just noted, can it explain mass. In order to give particles any mass at all we have to introduce the notional Higgs boson; whether it actually exists is a matter for 21st century physics. As Feynman cheerfully observed: "[---3---]"

In an attempt to draw everything together, physicists have [-4-] something called superstring theory. This postulates that all those little things like quarks and leptons that we had previously thought of as particles are actually "strings"—[---5---] The strings are very tiny—tiny enough to [-6-] point particles.
