5、in Switzerland. After the startling news spread out, scientists in the West who were indulged in the research of anti-matter were greatly excited. While they were attempting to produce and store anti-matter as the energy

6、 for spacecraft, they raised a new question: Many of the mysterious nuclear explosions in the recent one hundred years are connected with anti-matter. That is to say, these hard-to-explain explosions are tricks played by

7、 anti-matter. They are the “destruction” phenomenon caused by the impact between matter and anti-matter.V. GroupingA. Uncertainty:what if, illusory, indescribable, puzzle, speculation, seemingly, in some mysterious wayB.

11、he pieces are there, and even unfinished, it is arguably the most brilliant opus in the literature of physics. With great precision, it describes all known matter – all the subatomic particles such as quarks and leptons

12、– as well as the forces by which those particles interact with one another. These forces are electromagnetism, which describes how charged objects feel each other’s influence: the weak force, which explains how particles

13、 can change their identities, and the strong force, which describes how quarks stick together to form protons and other composite particles. But as lovely as the Standard Model’s description is, it is in pieces, and some

14、 of those pieces – those that describe gravity – are missing. It is a few shards of beauty that hint at something greater, like a few lines of Sappho on a fragment of papyrus.V. GroupingA. Particle physics:supersymmetry,
